Iron deficiency continues to be one of the most persistent nutritional challenges worldwide, especially in populations that rely heavily on plant-based diets. While the diet provides iron either through iron-rich dietary diversity or food fortification, the problem isn’t only how much iron we eat - It is also how much iron our bodies can absorb. This is where one simple nutrient, Vitamin C, plays a crucial role. Decades of nutrition research have consistently highlighted Vitamin C (ascorbic acid) as the most potent enhancer of non-heme iron absorption, especially in diets that are naturally high in inhibitors like phytates and polyphenols. How Does Vitamin C Improve Iron Absorption? Vitamin C improves iron absorption through two powerful biochemical actions:
This makes Vitamin C uniquely effective in the Indian dietary context, where most iron comes from cereals and pulses, and inhibitors are naturally high. Research shows that even small amounts of Vitamin C can make a big difference. An intake of about 25–50 mg per meal or an AA: Fe molar ratio of 2:1 to 4:1 can increase absorption by 2–7 times depending on the meal composition. Higher ratios are especially helpful in meals that are rich in phytates. In everyday diets, these benefits show up more evidently. For example:
What Do Fortification Trials Show? Recent studies reinforce Vitamin C’s role not just on the plate, but also in food fortification. Laboratory trials on wheat flour fortification show that adding Vitamin C can substantially boost iron uptake. A 2025 study on whole wheat flour (WWF) found that fortifying flour with Vitamin C significantly improved iron solubility and bio-accessibility:
These improvements were greater than those achieved by NaFeEDTA before cooking. However, once chapatis were cooked, Vitamin C’s advantage dropped sharply due to heat degradation, sometimes performing similarly to or lower than NaFeEDTA. The study concluded that Vitamin C fortification is effective and surprisingly economical (≈₹87.5/tonne), but its benefits depend heavily on how the food is processed. Further evidence from other fortified foods shows a clear synergistic effect of ascorbic acid.
Together, these studies show that Vitamin C can substantially enhance iron absorption in fortified foods, but the extent of benefit depends on processing conditions, especially heat exposure. Why Is Vitamin C Not Added to Flour? Despite its clear synergistic benefits, Vitamin C is rarely used in the mass fortification of cereals. The reason is simple but significant: Vitamin C is highly unstable. It degrades rapidly when exposed to: heat, light, oxygen, and moisture. This means that 50–80% of added Vitamin C can be lost during storage, cooking, or even during transportation in warm, humid climates. In wheat-based foods - typically baked, roasted, or boiled- Vitamin C often degrades too quickly to improve absorption. Because of this instability, fortification programs worldwide (and FSSAI’s fortification regulation in India) do not include Vitamin C in their flour fortification guidelines. Can Vitamin C Still Play a Role in Fortification? Vitamin C can strengthen iron absorption in fortified foods, but only under the right conditions. Its use depends on how the food is processed, stored and delivered. Here are the specific cases in which Vitamin C can still be used effectively in fortification: 1. When Processing is Controlled Fortified foods like infant cereals, ready-to-eat cereals, powdered beverages, or food-aid blends have successfully used Vitamin C and have been shown to improve iron absorption efficiency. These products are produced under low-oxygen conditions and packaged to protect the vitamin, keeping it intact until consumption. 2. Through Microencapsulation Encapsulating Vitamin C (e.g., ethyl cellulose coating) helps protect it from oxidation. Microencapsulation refers to wrapping Vitamin C in a protective layer so it survives heat, moisture and storage until the food is eaten. This method improves stability in food-aid blends, but increases cost and requires specialised processing. 3. Point-of-use Addition Micronutrient powders (‘Sprinkles’) combine iron and Vitamin C in single-use sachets. When added directly to cooked food, Vitamin C remains active and boosts iron absorption. This works well for targeted interventions, but is difficult to scale in large public systems like the Public Distribution System (PDS) and large-scale fortification in the open market. 4. Food-to-food Fortification Adding Vitamin C–rich ingredients (e.g., tomato, amla, guava, citrus) or natural powders directly to meals remains the simplest, most sustainable method. This approach works because the Vitamin C comes from fresh or minimally processed foods, which keeps it stable and highly effective at boosting iron absorption. The Bottom Line on Vitamin C and Iron Fortification Vitamin C is one of the most powerful and reliable enhancers of iron absorption we know. It can double or even triple iron uptake and can meaningfully improve haemoglobin when paired with iron-rich foods. But its fragility means that mass fortification of flour or cereals with Vitamin C is challenging and often not cost-effective. However, with further technological innovation and targeted research, more effective and practical ways to include Vitamin C could become feasible in the future. Vitamin C may not be the simplest fortificant, but when used smartly, it can be a game changer for iron nutrition. References:

By Tony Senanayake The National Convening on Food Fortification to Reduce Iron-Deficiency Anaemia was held in Delhi on November 4, bringing together leaders from academia, government, civil-society organisations and the private sector to discuss how to eliminate the scourge of hidden hunger that continues to weaken the nation. Hidden hunger—micronutrient deficiency—is an invisible disease affecting more than two-thirds of Indian children under five and over half of pregnant or lactating women. It robs millions of physical strength, learning potential and economic productivity. Anaemia, the most prevalent form, stems largely from a lack of iron in the diet and leads to fatigue, developmental delays and poor maternal outcomes. India has taken major steps to address this crisis through the nationwide rollout of rice fortification across social-safety-net programmes—an initiative that the Government of India recently extended through 2030. Yet a large gap remains: nearly 40 per cent of Indians, particularly in northern and western states, consume wheat rather than rice as their staple food. Mr Pawan Agarwal, CEO of the Food Future Foundation and former CEO of the Food Safety and Standards Authority of India (FSSAI), noted that India has already done the hard work—building regulatory frameworks, testing systems, supply-chain infrastructure and training mechanisms to scale rice fortification. “The next logical step,” he said, “is to build on this success to reach populations that primarily consume wheat.” The convening carried an unmistakable tone of optimism. Dr Rajan Sankar, former Senior Advisor at Tata Trusts, reminded participants that fortification is not a new idea: “The challenge now is scale, speed and urgency to truly eliminate hidden hunger.” Mr Alok Ranjan, former Chief Secretary of Uttar Pradesh, argued that nutrition must be viewed as a long-term investment in human capital, demanding political will, administrative leadership and efficient implementation. Private-sector representatives from The Akshaya Patra Foundation to premix vendors, equipment suppliers, and the Wheat Promotion and Production Society underlined their readiness to contribute, recognising that businesses are central to ensuring India’s nutritional security. Speakers agreed that scaling wheat-flour fortification will require four key enablers. 1. Leadership and Policy Coherence Participants highlighted the absence of a clear nodal department, either at the Centre or in states, to lead the anaemia-reduction agenda. Alignment among public-distribution and school-meal schemes and the Ministries of Health, Education, and Women and Child Development is essential. Political and administrative coherence can ensure that fortification moves from aspiration to implementation. 2. Implementation Quality and Evidence Success will depend on strong regulation, rigorous quality assurance and credible local evidence. Co-conveners IIT Delhi and the Central Food Technological Research Institute (CFTRI) noted that while abundant global evidence demonstrates the benefits of wheat-flour fortification, India must build its own data through high-quality evaluations and well-designed pilot programmes. Dr Prashanth Thankachan of St John’s Research Institute stressed embedding evaluation design in all future pilots, while Dr Sirimavo Nair of MS University reminded participants that fortification must complement, not replace, existing supplementation programmes. 3. Cost-Effectiveness, Innovation and Technology Fortification remains among the most cost-effective public-health interventions. Wheat flour can be fortified for less than ten paisa per kilogram—cheaper than rice fortification—while delivering comparable health gains. The economic logic is compelling: minimal cost, enormous social and productivity benefits. Technological innovation is making the process even more efficient. Ms Kalpana Bessabathuni of Hornbill Technologies shared an AI-based breakthrough that measures iron content in flour samples in real time, dramatically improving speed and accuracy. Equipment manufacturer, along with testing agencies demonstrated that India’s technical ecosystem is already capable of supporting large-scale implementation. 4. Public Awareness and Data Communication Hidden hunger must be made visible. Policymakers and citizens alike need to understand both its scale and its cost. Drawing on lessons from rice fortification, participants called for creative strategies—national awareness campaigns, visible labelling in school-meal programmes and collaborations with chefs and social influencers—to transform fortification from a policy initiative into a public movement. Ms Vedeika Shekhar of NITI Aayog emphasised that India’s nutrition story must be told through clear, relatable data drawn from the National Family Health Survey (NFHS) and the Household Consumption and Expenditure Survey (HCES). Communicating progress transparently can sustain political attention and citizen engagement. From Momentum to Movement The National Convening marked a pivotal step forward. India has already demonstrated bold leadership through rice fortification. Now, a coalition of government, academia, industry and civil society stands ready to complete the mission. The path ahead is clear: strengthen institutional leadership, invest in quality and evidence, harness innovation and affordability, and communicate the urgency of ending hidden hunger. If rice fortification laid the foundation for a healthier India, wheat can be its next frontier. With collective resolve and political will, the country can eliminate hidden hunger within the decade—ensuring that every household, in every state, enjoys not only food security, but true nutrition security.

Insights from the The Lancet Haematology Commission At Kilifi Hospital, Kenya, two mothers, Fatuma and Halima, shared the strain of caring for children hospitalised with severe anaemia. Both children received blood transfusions, but the mothers recalled not being given a clear explanation of what anaemia was. The emotional toll included tears, worry, and the constant stress of budgeting for food, transport, and hospital visits (Mutua & Atkinson, 2025). Their voices echo those of millions of families worldwide, including in India, where anaemia silently shapes futures. It is not just a clinical diagnosis, but an emotional, financial, and social burden falling most heavily on women and children. The Global Picture: Ambitious Goals vs Stark Realities Anaemia affects an estimated 1.9 billion people worldwide, primarily children, adolescent girls, and women of reproductive age. Yet, most countries remain off track to achieve the World Health Assembly and Sustainable Development Goal target of reducing anaemia prevalence by 50% by 2030 (Atkinson et al., 2025).  According to the recently published Lancet Haematology Commission, current global targets are unrealistic; health-economic modelling suggests a more feasible reduction of 12–22% by 2030 (Blythe et al., 2025). The World Health Organisation (WHO) and UNICEF have established the Anaemia Action Alliance (2021) and, in 2023, launched a Comprehensive Framework for Action. Yet measurable progress remains limited, with only 18 countries showing improvement (Rogers et al., 2025). Climate change is intensifying anaemia by lowering crop nutrient content, disrupting health systems, and driving disease risks. A study from Sub-Saharan Africa shows how even a 1°C rise is linked to a 13.8% increase in childhood anaemia (Fanzo & Carducci, 2025). The poorest, least able to adapt, bear the greatest burden, making nutrition central to climate resilience. India at the Epicentre India bears one of the highest burdens across all age groups. NFHS-5 shows more than half of women and two-thirds of children are anaemic, underscoring the scale of the challenge. To address this, Anaemia Mukt Bharat (AMB) was launched in 2018 as a paradigm shift, adopting a lifecycle, health-system approach. Anaemia Mukt Bharat incorporated the National Centre for Excellence and Advanced Research on Anaemia Control (NCEAR-A) at AIIMS as its technical hub. The centre leads research, training, digital innovation, and advocacy through strong partnerships. Future success depends on decentralised district-level implementation, sustained political commitment, and next-generation champions to ensure long-term impact. (Yadav, 2025) Why Fortification is India’s Best Bet Anaemia reduction strategies must balance effectiveness with affordability, especially in a country as large as India. A costing study (Oliver et al., 2025) estimated the per-person unit costs of six WHO-recommended interventions for women of reproductive age across 193 countries. The key finding was that “in most countries, food fortification and deworming were the lowest cost interventions, with population-weighted average costs of less than US$1 per person per year.” For India, this means fortification is not only cost-effective but also scalable, reaching millions through existing food systems without requiring radical infrastructure changes. Building on USAID’s Lessons: Why Sustained Commitment Matters Since 1961, USAID has shaped global nutrition through pioneering efforts in food fortification, vitamin A supplementation, and salt iodisation, contributing to reductions in anaemia and child mortality. It helped establish indicators, supported large-scale surveys, and fostered partnerships with WHO, UNICEF, and governments worldwide. Its closure in 2025 marked a major setback, risking the loss of decades of technical expertise and fragile program gains (Dary & Peniston, 2025). The lesson is clear: sustainable progress in anaemia control depends on long-term, consistent investment without which even the most effective strategies risk unravelling. Towards an Anaemia-Free Future Anaemia is the quiet thief of strength and dreams, draining lives in silence. Fortification stands out as one of the most cost-effective and scalable solutions. What is needed now is collective will, smart investment, and integrated action to ensure that no woman, child, or community continues to carry this burden. Fortify Health is working to turn this vision into reality by enabling access to wheat flour fortification by partnering with open-market millers and governments, so that every meal can carry the quiet power to fight anaemia and safeguard futures.

Iron deficiency doesn’t make headlines, but it should. Silently impacting millions across India, especially women and young children, iron deficiency is one of the main causes of anaemia and a major contributor to maternal deaths. The numbers speak for themselves: nearly three in five children under five, and half of all women of reproductive age, are anaemic. One of the most cost-effective ways to tackle this problem is by adding iron to everyday foods like wheat flour - a strategy backed by the World Health Organization. But there’s a catch: making sure the right amount of iron is added to the flour is no easy task. While there are advanced lab tests that can measure iron accurately, they’re expensive, time-consuming, and require skilled personnel. On the other hand, cheaper tests such as the iron spot test can be easily done at mills but rely heavily on human judgment, which can lead to errors. To bridge this gap, Fortify Health turned to technology to explore whether AI could help. In partnership with a graduate student from Georgia Institute of Technology (HaLim Jun), the team developed an early prototype of an AI-based solution in 2023. It uses simple images from the iron spot test and machine learning to estimate iron content more reliably. Encouraged by the advances in AI, Fortify Health collaborated with Hornbill Agritech, an AI specialist in food and agriculture, to develop a robust AI product that enhances quality control, making it smarter, faster, and more scalable, a crucial step toward reducing iron deficiency across the country. This is the first in Fortify Health’s series of blogs on our experience with AI. Enhancing Iron Fortification: AI for Accurate and Scalable Quality Control For many mothers in India, the consequences of iron deficiency and anaemia are life-threatening. Anaemia is a major contributor to maternal mortality in India, where the rate stands at 97 deaths per 100,000 live births. In 2020 alone, this resulted in around 20,000 women losing their lives due to pregnancy-related causes. Recognising the scale of the problem, the Government of India launched an initiative called Anaemia Mukt Bharat (Anaemia-Free India), which promotes a range of strategies to combat anaemia, including fortification of staple foods like wheat flour with iron and other essential micronutrients. In India, wheat flour (atta) is the second most widely consumed staple food, eaten daily by millions. It is one of the most powerful vehicles for delivering iron at scale. However, the effectiveness of flour fortification depends heavily on one crucial factor: ensuring the correct amount of iron is added in line with the Food Safety and Standards Authority of India (FSSAI)’s regulatory standards. If iron levels are inconsistent or incorrect, fortified foods may lose their intended health benefits and, in cases of excess, even pose safety risks. Despite this, flour producers often rely on a manual ‘iron spot test,’ which is quick and low-cost but can be inaccurate since it depends on human judgment. More accurate lab tests exist, but are expensive and slow, often taking over a week to deliver results. To advance quality control for iron-fortified flour, we have developed a machine-learning-based image processing pipeline that improves accuracy in measuring iron content in fortified wheat flour.. Our AI solution analyses images from the iron spot test, a quick but low-accuracy method, to predict iron levels with greater accuracy and objectivity. It can flag samples that fall outside safe ranges early, making quality control not only more precise but also faster and more affordable, while removing delays caused by laboratory testing. How Our AI Measures Iron in Flour or AI Methodology: Image Processing and Iron Content Estimation  Image processing pipeline An iron spot test image is first cropped and brightness-normalised to eliminate unnecessary background images and lighting bias; regions above a calibrated brightness threshold are masked to suppress glare. We then apply OpenCV’s multi-scale blob detector to isolate the iron-reaction spots and extract key features such as count and size. These descriptors feed a supervised learning model that estimates the flour’s iron concentration in real time. We tested two different models:
We tested five different models, including Gradient Boosting Regressor, K-neighbors regressor, Randomforest, Catboost Regressor, LGBM regressor, and support vector machine and statistical model for confidence interval.  We utilised a total of 213 datasets consisting of iron spot test images paired with their corresponding ground truth iron content. These datasets were created using two distinct methodologies:
Improved Accuracy and Impact: AI-Enhanced Quality Control High accuracy was achieved when training solely on the operational samples, with an error rate of just 12%. However, as more synthetic data was introduced, model performance declined. This was due to the synthetic samples including a wider range of iron concentrations, many of which rarely appear in real-world operational settings. This broader range caused a weaker correlation between the image features and the actual iron content. To address this, we adopted a multi-model classification strategy by overlaying two binary classifiers: one specialised in detecting whether a sample exceeds the safe iron concentration threshold, and another that identifies whether it falls below. By combining multiple models, we made the system more reliable, and it correctly identified results nearly 8 out of 10 times.[1]. (F1score - 77.8%) This innovative approach directly supports global and national guidelines recommending flour fortification as a cost-effective strategy to enhance nutrition and combat micronutrient deficiencies. By improving the reliability and efficiency of quality assurance, Fortify Health strengthens its ability to ensure regulatory compliance with standards like those set by the Food Safety and Standards Authority of India (FSSAI). This has a direct and meaningful impact on the lives of millions of people across India, particularly in regions where Fortify Health is actively working with 160+ open market millers to produce more than 40,000 MT of wheat flour each month. Next Steps: Scaling AI for Reliable Fortification Given the success of the early pilot, Fortify Health is now collaborating with Hornbill Agritech to build on this momentum and develop a large-scale, validated version of the AI tool. The goal is to develop a reliable and scalable product that can be made available as a public good to enhance quality control in wheat flour fortification. While this technology represents a significant advancement, like any new system, there are areas for continued refinement. Limitations identified include the need for ongoing training with new data, especially for flour samples with higher iron content. This is necessary to ensure accurate prediction across the full regulatory range. Furthermore, environmental variations during image capture, such as differing lighting, can affect the model's performance and require ongoing attention and mitigation strategies. Addressing these points through continued development and collaboration will be key to maximising the tool's potential.

(Source) -It means that with an estimated 20 thousand maternal deaths in 2020 (Link)  Tackling Iron Deficiency Anaemia Through Fortified Wheat Flour Iron deficiency anaemia affects millions in India, yet a simple, proven solution remains underutilised. Fortifying wheat flour with iron, folic acid, and vitamin B12 is a cost-effective and scalable way to address this public health challenge. According to the National Family Health Survey (NFHS-5), anaemia among children under five rose from 58.6% to 67.1% between 2015–16 and 2019–21. Among women of reproductive age, it increased from 53.1% to 57.0%. Despite the urgency, wheat flour fortification has seen slow uptake because of regulatory hurdles, limited market incentives, and low consumer awareness. To understand these barriers and identify what drives adoption, Fortify Health partnered with DevSol Research Consultant Pvt. Ltd. for a qualitative study. Insights From Seven States The study aimed to understand the factors that influence the adoption and sustainability of wheat flour fortification. It was conducted across seven Indian states: Maharashtra, Madhya Pradesh, West Bengal, Telangana, Karnataka, Rajasthan and Delhi, through in-depth interviews with 42 stakeholders. These included small, medium, and large-scale millers, regulatory officials, premix vendors, and members of the Fortify Health team. This broad approach provided a detailed view of the challenges and enablers across diverse operational contexts. Key Challenges in Wheat Flour Fortification While wheat flour fortification holds strong potential for improving public health, millers face a range of challenges that make adoption and sustainability difficult in the absence of external support. These challenges are not just technical or financial, but they’re shaped by a combination of market dynamics, consumer perceptions, and regulatory pressures. Understanding these barriers is key to creating more effective support systems and enabling wider adoption.
Despite these concerns, several millers acknowledged that repeated engagement, technical assistance, and high-quality premix quality from Fortify Health had helped rebuild their trust in fortification. A few millers noted that seeing other millers successfully sustain fortification efforts encouraged them to consider it more seriously. Key Enablers That Support Fortification While millers face several hurdles in adopting wheat flour fortification, many also pointed to strong enablers that supported their decision to fortify. These enablers were not limited to financial incentives or technical fixes; they reflected a mix of values, strategic goals, and confidence-building measures. Recognising and strengthening these enablers can help expand and sustain fortification efforts across India.
The Road Ahead for Wheat Flour Fortification Scaling up fortification requires greater awareness, stronger technical support, and a more enabling policy environment. Many millers said that more consumer education was essential and suggested running campaigns similar to those for iodised salt. “People are not aware of fortified flour. If they knew its health benefits, demand would increase—and more millers would be willing to fortify,” one miller said. Consistent technical support remains vital for ensuring compliance and quality control. A Fortify Health team member shared, “Millers often struggle with calibration, and regular support helps them maintain consistency.” To boost adoption, it’s crucial to reduce the cost burden and simplify regulatory processes, especially in the absence of strong consumer demand. As one non-partnered miller remarked, “Fortification adds to production costs, and without consumer demand, it’s hard to sustain.” Collaboration is key. Government agencies, regulators, industry players, and development organisations must work together to make fortification standard practice. With stronger cooperation and clear policy direction, fortification can become a widely adopted, sustainable solution. A Path to Better Nutrition Wheat flour fortification is a cost-effective and impactful strategy to improve nutrition in India. But its success depends on addressing operational, regulatory, and consumer awareness challenges. Fortify Health remains committed to supporting millers through technical assistance, capacity-building, and advocacy. By closing knowledge gaps and promoting cross-sector collaboration, we can move closer to reducing iron deficiency anaemia and achieving better public health outcomes. Stay connected with us!

Why India Removed Warning Labels on Fortified Foods for Thalassaemia and Sickle Cell Anaemia7/22/2025 Until recently, iron-fortified food packages in India carried this advisory: "People with Thalassemia may take it under medical supervision, and persons with Sickle Cell Anaemia are advised not to consume iron-fortified food products." But in July 2024, the Food Safety and Standards Authority of India (FSSAI) removed this advisory. Why the change? Fortified Foods Are Not the Real Concern Are fortified foods safe for everyone? This question often arises, particularly in the context of inherited blood disorders like Thalassemia Major and Sickle Cell Anaemia.
A common concern for people with these conditions is the risk of iron overload (too much iron in the body), primarily caused by frequent blood transfusions. Excess iron can damage vital organs, and many worry that consuming iron-fortified foods could add to this risk. However, the primary source of iron overload in these conditions is transfusion therapy, not foods like fortified wheat or rice. Here’s what the numbers say:
 The main reason for iron overload in these conditions is regular blood transfusions, not food like fortified wheat or rice. The amount of iron from fortified wheat or rice is too small to significantly increase iron levels. Plus, the body has its own way of controlling how much iron it takes in from food, which makes the risk from daily meals even lower. What Does Global Evidence Say? Iron fortification is not new. It has been extensively studied by experts across the world and is recognised as a proven, cost-effective strategy to combat iron deficiency - the leading cause of anaemia globally. Globally, over 90 countries have adopted wheat or rice fortification to tackle iron deficiency and anaemia. The scientific consensus is clear:
Most individuals with these conditions receive targeted medical care based on their needs, and very few countries have special dietary restrictions in place. This reinforces global evidence that fortified foods, when part of a balanced diet and proper treatment, pose minimal risk—even for people with blood disorders. Managing Iron Overload Through Clinical Care, Not Food Restrictions Iron overload is a complex condition that cannot be managed by avoiding iron-rich foods alone. It requires consistent medical care. Doctors often prescribe iron chelation therapy, which uses medication to safely remove excess iron from the body. This is typically supported by other treatments such as folic acid supplementation, pain management, and, in some cases, bone marrow transplants—all of which help improve health outcomes and quality of life. Screening programmes like prenatal tests and newborn checks help catch these conditions early. India’s Sickle Cell Anaemia Elimination Mission plays an important role in early detection. People screened for the condition are given colour-coded cards—blue for men, pink for women—indicating whether they are carriers or have the disease. These cards help healthcare workers provide targeted care and support couples in making informed decisions around marriage or pregnancy.  With early diagnosis, regular monitoring, and appropriate treatment, iron levels can be effectively controlled. Fortified foods, providing only a small fraction of daily iron needs, do not cause overload. Instead, they can support better nutrition in people with or without these conditions, when backed by the right care.
Removing Labels Helps Avoid Unwarranted Fear Since 2021, iron-fortified food packages in India have carried warning labels advising individuals with Thalassaemia Major and Sickle Cell Anaemia to either avoid them or consume them only under medical supervision. However, in July 2024, India’s food authority—the Food Safety and Standards Authority of India (FSSAI)—revoked this advisory. The decision followed a review conducted by a committee chaired by the Director General of the Indian Council of Medical Research (ICMR) and approved by the Ministry of Health and Family Welfare. Evidence shows that the small quantity of iron added during food fortification does not pose a genuine risk of iron overload. Fortified foods help fill critical nutritional gaps and typically provide only a fraction (30–50%) of the recommended daily iron intake. Removing these labels enables individuals to consume fortified foods without undue concern, while still emphasising the importance of medical care where required. It represents a shift towards science-based policy and improved public understanding. The Way Forward India’s removal of caution labels on iron-fortified foods reflects a growing consensus that, with stronger evidence, we can shift from broad warnings to informed decision-making. The way forward lies in the balance—not in blanket restrictions or blind reassurance, but in thoughtful action grounded in science, compassion, and care.
Fortified foods are a safe and effective tool to combat iron deficiency when supported by medical care and clear communication. Removing caution labels is a step toward more inclusive, evidence-based nutrition policies. Could Fortified Staples Fill the Gap? Mapping Iron Intake Across India: What the Data Reveals India has made a strong push toward food fortification in its efforts to combat iron deficiency and anaemia. But how much iron are Indians consuming from their daily diet? And how much iron does fortification add? Even though vegetables, cereals, and pulses are a big part of Indian diets, our analysis shows that they often don’t provide enough iron, especially for women and children in many states. When fortified staples, wheat flour, rice, and double fortified salt (DFS), are consumed regularly, they can contribute iron amounts nearly equal to those from the regular diets., Fortification has the potential to almost double total daily iron intake and close the nutritional gap in states with high staple consumption. This has major implications for rural areas and vulnerable groups, where nutritional needs and anaemia prevalence are high and dietary diversity is limited. The impact of fortification isn’t equal across the country - it varies by region, diet, and food access, making a case for more targeted and data-driven nutrition strategies. Our recent analysis, using national consumption data (HCES 2011-12), estimates iron intake across Indian states from the regular diet, based on food iron values from the Indian Food Composition Tables (IFCT) and ICMR-NIN RDA 2024 It also models the additional contribution from fortified staples (wheat flour, rice, and salt) using Indian standards recommended by FSSAI. The results highlight key rural-urban and state-wise patterns in total iron availability. How Much Iron Are We Getting? At the national level, rural and urban populations show similar iron intake from the regular diet (intrinsic/natural iron from the food source) (~20 mg/day), but fortification significantly increases iron intake. As shown in Figure 1, the contribution from fortification is almost equivalent (an additional 15–18 mg/day) to that of the regular diet, underscoring its significance.  Where Is the Iron Coming From? - Major Contribution of Food Groups Iron from natural diet comes from a wide range of food groups like vegetables, cereals, pulses and legumes, fruits, dairy, meat, egg, nuts and oil seeds. Vegetables and cereals are the primary contributors to iron intake in rural and urban diets, jointly accounting for nearly 90% of total iron. However, urban diets tend to show a higher share of iron from vegetables, reflecting greater access to a variety of fresh produce, and a more diverse intake across food groups like pulses, milk, meat, and fruits. (Figures 2a & 2b). This dietary diversity in urban areas may be influenced by better market access, higher income levels, and changing food preferences, which collectively support a more balanced iron profile beyond staple cereals.  How Does This Compare with Iron Requirements? According to the ICMR-NIN 2024 recommendations, the daily iron requirement (RDA) varies by age, sex, and physiological status. Women of reproductive age have higher iron intake requirements - 29 mg/day for adult women, 27 mg/day for pregnant women, and 23 mg/day for lactating women, with a Tolerable Upper Limit (TUL) of 45 mg/day for most adults. Our modelling analysis shows that in many states, women of reproductive age, including pregnant and lactating women, fall short of these recommended intake levels when relying solely on dietary sources in the regular diet (Figure 3a & 3b). Given their increased physiological demand and high risk of iron deficiency, fortified staples serve as a critical intervention to bridge this gap and improve iron adequacy in these vulnerable populations. State-wise Trends in Iron Intake Our analysis of diets across states shows big differences in how much natural and fortified iron people get. This is mainly due to the types of staples they eat, how varied their diets are, and how easily they can access fortified foods. Some states show relatively high total iron intake, largely due to higher consumption of iron-rich cereals like wheat and widespread fortification coverage. Iron intake from fortified staples is closely linked to the consumption patterns of wheat and rice (Figures 3a and 3b). States with high rice consumption, such as Tripura, Manipur, Nagaland, Mizoram, Arunachal Pradesh, and Assam and those with high wheat consumption, like Rajasthan, Punjab, Haryana, and Madhya Pradesh, show relatively higher total iron intake when fortification is layered on top of their staple diets. In contrast, states like Kerala, Goa, and many northeastern states tend to have lower total iron availability, especially in rural areas, due to lower staple consumption and/or comparatively reduced dietary diversity. Fortification’s Role in Bridging the Gap The inclusion of fortified staples like wheat flour, fortified rice, and DFS (double fortified salt) plays a pivotal role in closing this gap in many states (Figure 3a & 3b). In several regions, fortification provides an additional intake of iron almost equal to natural iron received from the regular diet, significantly improving adequacy without causing excess iron intake crossing the TUL. This helps fill the shortfall of required dietary intake, especially for rural populations who consume large quantities of staples but have limited dietary diversity and women and children with higher requirements (Figure 1 shows the additional contribution of iron from different fortified staples for the All India Population).   Key Implications for Food Fortification Policy and Programmes
Final Thoughts Fortification is a significant public health tool, but data-driven strategies are key to maximising its impact while avoiding excess intake.

How much iron is being added to wheat flour during fortification? And how do we know if it’s enough, or too much? This remains one of the biggest technical challenges in India’s fortification landscape. While India has clear standards from the Food Safety and Standards Authority of India (FSSAI) for iron levels in fortified wheat flour, measuring the actual added iron, not just the total iron content, is a complex process. Accurate measurement is essential to ensure both the safety and effectiveness of wheat flour fortification. Why measuring added iron matters Getting the amount of added iron right matters because it directly affects health outcomes. Iron deficiency anaemia is one of India’s most persistent public health challenges, affecting millions, particularly women and children. When iron levels in fortified flour are too low, the intervention may fail to make an impact. Too high, and it may pose health or regulatory concerns. Methods for detecting Iron in fortified wheat flour There are various methods, ranging from advanced laboratory techniques to simpler field-based approaches, to help determine iron levels in fortified wheat flour. Table 1. Methods for detecting Iron in wheat flour  Key challenges in determining added iron in wheat flour 1. Natural vs. Added Iron: A Complicated Distinction Wheat contains natural iron. The challenge lies in accurately determining how much iron has been added during fortification. Most of the laboratory methods determine only the total iron content. When these methods are used to test fortified wheat flour, they provide the total iron content, which includes natural iron from wheat and added iron. 2. Challenges in Sampling Fortified and Unfortified Flour There is one way to determine the added iron content using these conventional methods. We can test fortified wheat flour samples and unfortified wheat flour samples from the same batch. Subtracting the total iron content of the unfortified sample from that of the fortified sample will give us the added iron content. But the key challenge here is that the natural iron content in wheat flour can vary from lot to lot and getting both the fortified and unfortified samples from the same lot every time is difficult. This limits the accurate estimation of the added iron content. 3. Testing Limitations: Qualitative vs. Quantitative Methods Although most of the laboratory methods like AAS and ICP-OES, measure only the total iron content, there is one test that can detect the added iron. It is known as the Iron Spot Test (IST). It produces red coloured spots in proportion to the added iron present in the sample. However, the problem is that counting these spots and estimating the exact amount of added iron is very difficult. Thus, we can use IST only in a qualitative manner. Colourimetric methods offer better detection of added iron and iron salt types but have sensitivity limits. Techniques like EDXRF show promise for rice but might have limitations on powdered materials like wheat flour and hence need validation.

Variability in Iron Fortificants Different iron compounds used in fortification, such as ferrous sulfate, ferrous fumarate, and NaFeEDTA, interact differently with wheat flour. Some dissolve easily and are more bioavailable, while others are less soluble and harder to detect. Encapsulated iron, which prevents changes in flour colour and taste, further complicates measurement. Inconsistencies in testing methods across different laboratories and regions lead to discrepancies in reported iron levels. Without standardised protocols, comparing results becomes difficult, making regulatory compliance more complex. Overcoming the challenges To make sure that fortified wheat flour meets the right amount of added iron, a reliable testing method is essential. Colourimetric methods can differentiate between iron forms and can determine added iron. Unlike expensive and complex lab instruments, colorimetric tests are affordable and portable. This makes them practical for field testing, especially in regions where access to high-end lab equipment is limited. Fortify Health is working on identifying and validating a method that can selectively determine added iron in fortified wheat flour. By refining analytical techniques, the organisation aims to develop an accurate and accessible testing method that differentiates between natural and added iron. This approach will improve fortification monitoring, enhance quality control, and support regulatory compliance, ensuring that fortified wheat flour delivers its intended nutritional benefits effectively.

A new meta-analysis by Fortify Health explores the impact of NaFeEDTA (sodium iron ethylenediaminetetraacetate) fortification on iron levels and anaemia prevalence. NaFeEDTA is a highly bioavailable form of iron that binds to a compound (EDTA) to improve iron absorption, especially in diets rich in grains and legumes, where natural inhibitors can block iron uptake. The findings suggest that adding NaFeEDTA to staples like wheat flour and rice significantly improves iron absorption and reduces the risk of anaemia.
What did the research find? The meta-analysis findings from the seven selected studies reveal that fortifying foods with NaFeEDTA leads to an average increase of 3.93 g/L in haemoglobin levels. Haemoglobin, the crucial component in red blood cells responsible for carrying oxygen, when available in sufficient levels, means better energy and overall well-being for those consuming fortified foods. This increase suggests that fortified foods could boost the iron status of those who consume them regularly. Furthermore, our analysis indicates a significant 16% reduction in the risk of anaemia. This suggests that by fortifying staple foods with NaFeEDTA, we could see a substantial decrease in the number of people affected by anaemia, which can lead to fatigue, weakness, and other health problems. The research also found that a weekly intake of at least 20 mg of NaFeEDTA is essential for effective results in reducing anaemia. Lower amounts appear less impactful in reducing anaemia. How was this research conducted? The Fortify Health team followed a structured methodology for this meta-analysis, which included five stages :
This meta-analysis was undertaken to provide more specific evidence on the effectiveness of NaFeEDTA, as previous broader analyses may have included studies with different iron fortificants and varying methodologies. Understanding the impact of NaFeEDTA is important for informing public health interventions aimed at reducing iron deficiency. Why does NaFeEDTA work so well? The meta-analysis highlights NaFeEDTA as a particularly effective fortificant. But why is that?
While the results of this meta-analysis are encouraging, the researchers note some areas for future research. Many of the included studies focused on children, and further research involving adults and pregnant women would be valuable. Additionally, investigating the long-term effects of NaFeEDTA fortification and exploring optimal dosages for various populations could provide further insights. Examining the application of NaFeEDTA fortification in a wider variety of staple foods beyond wheat and rice may also be beneficial. In conclusion, this meta-analysis suggests that fortifying staple foods with NaFeEDTA can lead to improvements in haemoglobin levels and a reduction in anaemia prevalence. These findings contribute to the evidence base for using food fortification as a public health strategy to address iron deficiency.

Wheat consumption patterns in India are changing, and so is the fight against anaemia. The latest Household Consumption and Expenditure Survey (HCES) 2022-23 reveals shifts in cereal consumption across states, impacting how we approach wheat flour fortification. In 11 Indian states, wheat consumption accounts for more than 50% of the total cereal consumption. Understanding these trends is critical to strengthening Fortify Health’s fortification program and tackling iron deficiency anaemia effectively. About the HCES survey The Household Consumption and Expenditure Survey (HCES) is a crucial dataset published by the Government of India once every decade. It provides detailed information on the monthly per capita consumption of various food items, consumer goods, and the Monthly Per Capita Consumption Expenditure (MPCE) for these items. The most recent HCES survey was conducted in 2022-23, and the preliminary report (Report no. 591) was released in June 2024. Importance of HCES data for Fortify Health’s chakki atta fortification program Understanding consumption patterns of wheat and wheat flour in India is crucial for Fortify Health’s initiatives as it provides state-wise information on food consumption, including wheat. We have used this information to calculate the beneficiaries we reach through consumption of fortified chakki atta. The HCES data serves as a reliable source for this information and we also use it for the strategic planning of the expansion of wheat flour fortification efforts in India. Key takeaways from HCES 2022-23 1. Cereal Consumption in India is Declining (Fig. 1 and 2) Data from the survey shows that overall cereal consumption has dropped significantly between 2011-12 and 2022-23. On average:
The most significant decline was observed in rice consumption among the rural population, while coarse grains such as millet saw a reduction in both rural and urban areas. Wheat consumption also declined slightly across both groups.  Fig. 1: Cereal consumption in rural India  Fig. 2: Cereal consumption in urban India 2. Wheat is the Staple in 11 Key States (Fig. 3 and 4) While India is diverse in food habits, wheat remains the primary staple in 11 states, where it accounts for more than 50% of total cereal consumption. A total of 38% Indian population resides in these 11 states in 2023, as per the population projection report 2020 by the National Commission on Population. Rajasthan, Haryana, Madhya Pradesh, and Punjab have the highest per capita wheat consumption. However, wheat consumption in these states decreased from 2011-12 to 2022-23, with the exception of Gujarat, where wheat consumption increased in both rural and urban populations.  Fig. 3: States with more than 50% contribution of wheat in cereal consumption rural India  Fig. 4: States with more than 50% contribution of wheat in cereal consumption in urban India 3. Anaemia prevalence in top wheat-consuming states (Fig.5) According to the National Family Health Survey (NFHS-5, 2019-21), top wheat-consuming states also have high rates of anaemia among women aged 15-49. Gujarat has the highest prevalence of anaemia, while Haryana, Chandigarh, and Punjab have anaemia rates above the all-India average. In all of these states, wheat consumption accounts for more than 55% of total cereal consumption. Other states also show anaemia prevalence rates of 50% or higher, except Uttarakhand.  Fig. 5: Wheat consumption and Anaemia status in top wheat consuming states What this means for Fortify Health
The HCES 2022-23 data plays a crucial role in shaping Fortify Health's strategies and action plans. Chakki atta contains an average of 41 mg/kg of iron, according to the Indian Food Composition Table 2017. The decline in wheat consumption across major states indicates a lower intake of dietary iron from wheat. Expediting Fortification Efforts: The HCES 2022-23 data helped Fortify Health expedite fortification efforts in states like Gujarat, Haryana, Uttar Pradesh, and Rajasthan through open-market wheat flour mill partnerships, and toward Chandigarh and Punjab via government partnerships. The combination of higher wheat consumption and high anaemia prevalence in these states made them priority areas for our chakki atta fortification program to achieve maximum impact. Strategic Expansion: Looking ahead, we plan to expand our efforts in Himachal Pradesh and Uttarakhand. Given its high anaemia prevalence and increasing wheat consumption, Gujarat can be a key focus for our work moving forward. These strategic decisions are directly informed by the detailed consumption and health data provided by the HCES 2022-23. Our strategies are guided by data and aimed at making fortification accessible where it’s needed most.
