Large-scale food fortification has great potential to improve child health and nutrition.

PURPOSE OF REVIEW: Undernutrition, including micronutrient deficiencies, continues to plague children across the world, particularly in low and middle-income countries (LMICs). The situation has worsened alongside the SARS-CoV-2 pandemic because of major systemic disruptions to food supply, healthcare, and employment. Large-scale food fortification (LSFF) is a potential strategy for improving micronutrient intakes through the addition of vitamins and minerals to staple foods and improving the nutritional status of populations at large. RECENT FINDINGS: Current evidence unquestionably supports the use of LSFF to improve micronutrient status. Evidence syntheses have also demonstrated impact on some functional outcomes, including anemia, wasting, underweight, and neural tube defects, that underpin poor health and development. Importantly, many of these effects have also been reflected in effectiveness studies that examine LSFF in real-world situations as opposed to under-controlled environments. However, programmatic challenges must be addressed in LMICs in order for LSFF efforts to reach their full potential. SUMMARY: LSFF is an important strategy that has the potential to improve the health and nutrition of entire populations of vulnerable children. Now more than ever, existing programs should be strengthened and new programs implemented in areas with widespread undernutrition and micronutrient deficiencies.

Management of severe acute malnutrition by cow milk in resource constraints settings: experience of the Nutritional Centre of the University Clinics of Graben.

BACKGROUND: Severe acute malnutrition is defined as a weight for height z-score < - 3 standard deviation. Since 2000, joint efforts of the World Health Organization and United Nations Children's Fund allowed to standardize the management of acute malnutrition by improving outcome and preventing complications with the introduction of therapeutic milk and ready-to-use therapeutic foods. However, in the Democratic Republic of Congo, many health facilities face therapeutic milk shortage while managing severe acute malnutrition. At the University Clinics of Graben, cow milk with porridge made of maize, soybean, vegetal oil and sugar is used during stockouts periods. This study was carried out to analyse the efficiency and safety of this treatment compared to the conventional one in SAM patients. METHODS: This study is based on the experience of the University Clinics of Graben in eastern Democratic Republic of Congo whose nutritional centre is often confronted with stockouts in nutritional supplements. During a three months shortage in 2015, patients received cow milk alternating with preparations made from sugar-maize-soybean- vegetal oil. The study compared the evolution of these children with those who had previously been treated with the WHO conventional preparations by analysing weight changes, oedema resolution, gastrointestinal tolerability and clinical outcome over 21 days. Data were analysed with SPSS 20. We used the ANOVA, Chi-square test, odd ratio and p-value to compare the differences. RESULTS: Seventy-nine patients had received cow milk while fifty-seven were submitted to classical therapeutic milk. There was no significant difference between the two groups regardless the type of malnutrition in terms of weight changes, oedema resolution, gastrointestinal tolerability and clinical outcome over 21 days. CONCLUSION: Cow milk alternately with sugar-maize-soybean- vegetal oil preparations is an acceptable alternative in case of stockouts in conventional therapeutic milk in these settings.

[Effectiveness of the program "School Milk" for the prevention of iodine deficiency].

Republic of Bashkortostan refers to iodine-deficient regions of Russia. The incidence of endemic multinodular goiter in 2012 in the Republic amounted to 33.2 per 100 thousand of the population. The purpose of the study is to evaluate the effectiveness of group iodine prophylaxis of schoolchildren through the use of iodized milk. The study included 181 children of primary school (pre-pubertal) age (8-10 years), it has been carried out in accordance with the recommendations of the WHO and the International Council for Control of iodine deficiency disorders using a unified system of identification of iodine deficiency states. Level of physical development was assessed according to anthropometric measurements, which were conducted by centile distribution tables according to age and sex, and the individual assessment of physical development was determined by the level of feature by its position in a number of centile. Assessment of iodine deficiency was carried out by determining levels of iodine excretion in a single urine sample. Iodine concentration in urine was determined by ceric ion-arsenious acid method. Frequency of iodine deficiency varying degrees before the iodine prophylaxis among urban children was 57.0%, among rural-92.3%. Urban junior schoolchildren showed severe iodine deficiency in 12.7% and moderate one in 16.4% of the cases, while in the countryside their prevalence was higher--27.4 and 35.2%, respectively. It was revealed that the number of children whose body growth values are within the average values is 36% in urban children, and 48.4% in rural areas. It should be noted that the low and very low body height predominate in rural students, it makes up 16.1% (while in the town it makes-up 2.3%). Iodine prophylaxis contributed to a significant reduction of iodine deficiency in children. In the town the median urinary iodine exceeded 100 mg/L and amounted to 159.4 mg/L. After iodine prophylaxis 82.5% of urban children and 72.1% of rural showed normal urinary iodine. When comparing the results of clinical and laboratory studies before and after the group prevention of iodine deficiency there has been revealed a positive trend in terms of reflecting the tensions of thyroid status.

Modern India and Dietary Calcium Deficiency-Half a Century Nutrition Data-Retrospect-Introspect and the Road Ahead.

Calcium and vitamin D are inseparable nutrients required for bone health. In the past half a century, the dietary calcium intake of rural, tribal, and urban India has declined. Though India is the largest producer of milk and cereals, the major source of calcium in India is through non-dairy products. The highest intake of cereals and lowest intake of milk & milk products was observed in rural and tribal subjects whereas, the intake of cereals, milk & milk products were similar in both urban and metropolitan subjects. One of the reasons for lower calcium intake was the proportion of calcium derived from dairy sources. Over the past half a century, the average 30-day consumption of cereals in the rural and urban population has declined by 30%. The Per Capita Cereal Consumption (PCCC)has declined despite sustained raise in Monthly Per capita Consumption Expenditure (MPCE) in both rural and urban households. The cereal consumption was the highest in the lowest income group, despite spending smaller portion of their income, as cereals were supplied through public distribution system (PDS). About 85% of the Indian population are vitamin D deficient despite abundant sunlight. Dietary calcium deficiency can cause secondary vitamin D deficiency. Though India as a nation is the largest producer of milk, there is profound shortage of calcium intake in the diet with all negative consequences on bone health. There is a decline in dietary calcium in the background of upward revision of RDI/RDA. There is a gap in the production-consumption-supply chain with respect to dietary calcium. To achieve a strong bone health across India, it is imperative to have population based strategies addressing different segments including supplementing dietary/supplemental calcium in ICDS, mid-day-meals scheme, public distribution system, educational strategies. Other measures like mass food fortification, biofortification, bioaddition, leveraging digital technologies, investments from corporate sector are some measures which can address this problem. India is a vast country with diverse social, cultural and dietary habits. No single measure can address this problem and requires a multi-pronged strategic approach to tackle the dietary calcium deficiency to achieve strong bone health while solving the problem of nutritional deficiency.

Effects of food supplementation on cognitive function, cerebral blood flow, and nutritional status in young children at risk of undernutrition: randomized controlled trial.

OBJECTIVE: To assess the effects of food supplementation on improving working memory and additional measures including cerebral blood flow in children at risk of undernutrition. DESIGN: Randomized controlled trial. SETTING: 10 villages in Guinea-Bissau. PARTICIPANTS: 1059 children aged 15 months to 7 years; children younger than 4 were the primary population. INTERVENTIONS: Supervised isocaloric servings (≈1300 kJ, five mornings each week, 23 weeks) of a new food supplement (NEWSUP, high in plant polyphenols and omega 3 fatty acids, within a wide variety and high fortification of micronutrients, and a high protein content), or a fortified blended food (FBF) used in nutrition programs, or a control meal (traditional rice breakfast). MAIN OUTCOME MEASUREMENTS: The primary outcome was working memory, a core executive function predicting long term academic achievement. Additional outcomes were hemoglobin concentration, growth, body composition, and index of cerebral blood flow (CBFi). In addition to an intention-to-treat analysis, a predefined per protocol analysis was conducted in children who consumed at least 75% of the supplement (820/925, 89%). The primary outcome was assessed by a multivariable Poisson model; other outcomes were assessed by multivariable linear mixed models. RESULTS: Among children younger than 4, randomization to NEWSUP increased working memory compared with the control meal (rate ratio 1.20, 95% confidence interval 1.02 to 1.41, P=0.03), with a larger effect in the per protocol population (1.25, 1.06 to 1.47, P=0.009). NEWSUP also increased hemoglobin concentration among children with anemia (adjusted mean difference 0.65 g/dL, 95% confidence interval 0.23 to 1.07, P=0.003) compared with the control meal, decreased body mass index z score gain (-0.23, -0.43 to -0.02, P=0.03), and increased lean tissue accretion (2.98 cm2, 0.04 to 5.92, P=0.046) with less fat (-5.82 cm2, -11.28 to -0.36, P=0.04) compared with FBF. Additionally, NEWSUP increased CBFi compared with the control meal and FBF in both age groups combined (1.14 mm2/s×10-8, 0.10 to 2.23, P=0.04 for both comparisons). Among children aged 4 and older, NEWSUP had no significant effect on working memory or anemia, but increased lean tissue compared with FBF (4.31 cm2, 0.34 to 8.28, P=0.03). CONCLUSIONS: Childhood undernutrition is associated with long term impairment in cognition. Contrary to current understanding, supplementary feeding for 23 weeks could improve executive function, brain health, and nutritional status in vulnerable young children living in low income countries. Further research is needed to optimize nutritional prescriptions for regenerative improvements in cognitive function, and to test effectiveness in other vulnerable groups. TRIAL REGISTRATION: ClinicalTrials.gov NCT03017209.

[Folic acid fortified foods available in Spain: types of products, level of fortification and target population groups]. / Alimentos fortificados con ácido fólico comercializados en España: tipo de productos, cantidad de ácido fólico que proporcionan y población a la que van dirigidos.

INTRODUCTION: Folic acid is a potentially relevant factor in the prevention of a number of pathologies (congenital abnormalities, cardiovascular disease, colorectal cancer and neurocognitive decline). This has led to the introduction of different strategies in order to increase folate intake: nutritional education, pharmacological supplementation and mandatory or voluntary fortification of staple foods with folic acid. In Spain there is a growing number of folic acid fortified products on a voluntary basis, but there is also a lack of reliable data to assess their impact on the population's dietary folate intakes. OBJECTIVE: To gather a better knowledge of folic acid food fortification practices in Spain. METHODS: A Food Composition Database was developed using data from a market study. Also, previously published data of unfortified staple foods from Food Composition Tables was reviewed. RESULTS AND DISCUSSION: The Database included 260 folic acid fortified food items and it was periodically updated. Food groups included were primarily "Cereals and derivatives" (52%) followed by "Dairy products". Most of these foodstuffs lacked a target population for their consumption (37%) or were aimed at "Weight control" (28%) and "Children" (23%), but only 2% targeted women at a reproductive age. Number of unfortified foods included was 690. Fortification levels declared by manufacturers ranged between 15 and 430% of the Recommended Dietary Allowances (RDA) for folic acid per 100 g/ml, and simultaneous addition of B6 and B12 vitamins was observed in 75% of the products. Currently, Spain market offers a significant number of folic acid fortified products on a voluntary basis and at a level > or = 15% of the RDA per 100 g/ml or serving declared by manufacturers.

Iodine status of non-pregnant women and availability of food vehicles for fortification with iodine in a remote community in Gulf province, Papua New Guinea.

Adequate iodine status of women of childbearing age is essential for optimal growth and development of their offspring. The objectives of the current study were to assess the iodine status of non-pregnant women, availability and use of commercial salt, extent to which it is iodised, and availability of other industrially processed foods suitable for fortification with iodine. This prospective cross-sectional study was carried out in 2018 in a remote area in Gulf province, Papua New Guinea. Multistage cluster sampling was used to randomly select 300 women visiting local markets. Of these, 284 met study criteria of being non-pregnant and non-lactating. Single urine samples were collected from each of them. Discretionary salt intake was assessed; salt samples were collected from a sub-sample of randomly selected households. A semi-structured, pre-tested questionnaire to assess use and availability of commercial salt and other processed foods was modified and used. Salt was available on the interview day in 51.6% of households. Mean iodine content in household salt samples was 37.8 ± 11.8 ppm. Iodine content was below 30.0 ppm in 13.1% and below 15.0 ppm in 3.3% of salt samples. Mean iodine content of salt available at markets was 39.6 ± 0.52 ppm. Mean discretionary intake of salt per capita per day was 3.9 ± 1.21 g. Median UIC was 34.0 µg/L (95% CI, 30.0-38.0 ppm), indicating moderate iodine deficiency. For women with salt in the household, median UIC was 39.5 µg/L (95% CI, 32.0-47.0 µg/L), compared to median UIC of 29.0 µg/L (95% CI, 28.0-32.0 µg/L) for those without salt. This community has low consumption of iodised salt, likely due to limited access. Investigation of other industrially processed foods indicated salt is the most widely consumed processed food in this remote community, although 39.8% of households did use salty flavourings.

Prevention of Micronutrient Deficiencies in Young Children: Consensus Statement from Infant and Young Child Feeding Chapter of Indian Academy of Pediatrics.

JUSTIFICATION: Micronutrient deficiencies have significant impact on the overall health and well-being of society and potential targets for supplementations. It is important to formulate a consensus statement in view of current evidence, and put in place strategies to meet targets. OBJECTIVE: To formulate by endorsement or adoption and disseminate a consensus statement for prevention of micronutrients deficiencies in young children for office practices from an Indian perspective. PROCESS: A National Consultative Meeting was convened by Infant and Young Child Feeding Chapter (IYCF) of Indian Academy of Pediatrics (IAP) on 17 December, 2016 at Mumbai. IYCF chapter, IAP, United Nations Children Fund, National Institute of Nutrition and Government of India were the participating agencies; and participants representing different parts of India were included. CONCLUSIONS: Micronutrient deficiencies are widespread. For its prevention proper maternal and infant-young child feeding strategies need to be practiced. Encourage delayed cord clamping, dietary diversification, germinated foods, soaking and fermentation processes. Existing Iron, Vitamin A, Zinc supplementation and universal salt iodization programs need to be scaled up, especially in high risk groups. Universal vitamin D supplementation need to be in place; though, the dose needs more research. Vitamin B12 deficiency screening and supplementation should be practiced only in high-risk groups. Availability of appropriately fortified foods needs to be addressed urgently.

[Dietary iodine provision of the population in the Krasnoyarsk Territory].

The paper analyzes the time course of changes in the intake of staple foods in the Krasnoyarsk Territory in 1998-2005. It is shown that the ingestion of iodine-rich foods has not increased greatly and it is low and does not provide the population with this essential micronutrient. The actual content of iodine in the study samples of food and its raw material is several times less than the tabulated values. The contribution of the staple foods to the provision of the Krasnoyarsk Territory's population with iodine is assessed. The total level of dietary iodine deficiency is estimated. Iodine-fortified salt and foods should be widely used under special conditions providing the transportation and storage of biologically value foods, during which there are inevitable losses of the trace element occur.

A 2017 global update on folic acid-preventable spina bifida and anencephaly.

BACKGROUND: Spina bifida and anencephaly are largely preventable birth defects through mandatory folic acid fortification. Our objective was to estimate the proportion of folic acid-preventable spina bifida and anencephaly (FAP SBA) prevented worldwide through mandatory fortification of wheat and/or maize flour with folic acid during the year 2017. METHODS: Using existing data, we identified countries with mandatory fortification policies that added at least 1.0 ppm folic acid to wheat and/or maize flour and had information on percentage of industrially milled flour that is fortified. We assumed mandatory folic acid fortification at 200 µg/day of folic acid fully protects against FAP SBA, reducing the prevalence of spina bifida and anencephaly to 0.5 per 1,000 live births. RESULTS: Overall, 59 countries met our criteria for implementing mandatory folic acid fortification of wheat and/or maize flour in 2017. These countries prevented about 50,270 out of 280,500 FAP SBA births in 2017. Thus, we have only achieved 18% prevention of FAP SBA worldwide. Several countries in Africa and Asia with a high number of FAP SBA-affected births do not have mandatory fortification. CONCLUSION: About 230,000 children unnecessarily developed FAP SBA globally in 2017. There is an urgent need for all countries to implement mandatory folic acid fortification, a proven, safe public health intervention that saves money and prevents infant mortality and disability. Prevention of FAP SBA can play an important role in helping countries to achieve their Sustainable Development Goals for health.

The Availability and Nutritional Adequacy of Gluten-Free Bread and Pasta.

Management of coeliac disease (CD) requires the removal of gluten from the diet. Evidence of the availability, cost, and nutritional adequacy of gluten-free (GF) bread and pasta products is limited. GF flours are exempt from UK legislation that requires micronutrient fortification of white wheat flour. This study surveyed the number and cost of bread and pasta products available and evaluated the back-of-pack nutritional information, the ingredient content, and the presence of fortification nutrients of GF bread and pasta, compared to standard gluten-containing equivalent products. Product information was collected from four supermarket websites. Standard products were significantly cheaper, with more products available than GF (p < 0.05). GF bread products were significantly higher in fat and fiber (p < 0.05). All GF products were lower in protein than standard products (p < 0.01). Only 5% of GF breads were fortified with all four mandatory fortification nutrients (calcium, iron, niacin, and thiamin), 28% of GF breads were fortified with calcium and iron only. This lack of fortification may increase the risk of micronutrient deficiency in coeliac sufferers. It is recommended that fortification legislation is extended to include all GF products, in addition to increased regulation of the nutritional content of GF foods.

Targeting the pains of food insecurity and malnutrition among internally displaced persons with nutrient synergy and analgesics in organ meat.

Living with pain is one of the distressing effects of food insecurity and malnutrition among millions of internally displaced persons (IDPs) worldwide. Vulnerability to emotional pain, metabolic imbalance, chronic illnesses and non-communicable diseases by IDPs are associated with stressed livelihood and restricted access to balanced diets in their camps. Tackling the complexity of issues related to internal displacement is challenging as 45% are globally trapped in protracted conditions. In this review, a diet-based intervention is proposed considering the potential benefits of nutrient synergy and analgesic constituents in organ meat. Providing an affordable, value added and well packaged nutrient dense diet is suggested to meet daily protein and micronutrient requirements from organ meat. Also, unlocking health-promoting bioactive substances and analgesics in restructured organ meat product is proposed as personalized dietary remedy to exert opioid bioactivity in food matrix. Exploiting the nutrient synergy of this animal by-product will not only improve the nutritional status or wellbeing but also raise the composite score of dietary diversity or food security index among IDPs by 2030.

Iron deficiency anemia (IDA) perceptions and dietary iron intake among young women and pregnant women in Jordan.

To determine Iron Deficiency Anemia (IDA) perceptions and iron dietary practices of Jordanian female students and pregnant women, a descriptive quantitative questionnaire was administered to 271 participants: 206 female students and 65 pregnant women. This pilot study found that most participants can identify foods containing iron, but lack appropriate iron intake, because of eating habits and finances; more than 50% report daily symptoms of IDA, including dizziness, fatigue, depression, headaches, and loss of concentration and memory. There are no statistically significant differences in IDA perceptions and iron-related dietary practices based on education, and relatively few based on where participants live, their available financial resources, or their position (pregnant women or young women). Culturally sensitive intervention research, which addresses application of IDA education principles, temporary supplementation, and adequate income for dietary modification and long-term iron supplementation to prevent IDA is warranted.

A comparison of substrate oxidation during prolonged exercise in men at terrestrial altitude and normobaric normoxia following the coingestion of 13C glucose and 13C fructose.

This study compared the effects of coingesting glucose and fructose on exogenous and endogenous substrate oxidation during prolonged exercise at altitude and sea level, in men. Seven male British military personnel completed two bouts of cycling at the same relative workload (55% Wmax) for 120 min on acute exposure to altitude (3375 m) and at sea level (~113 m). In each trial, participants ingested 1.2 g·min-1 of glucose (enriched with 13C glucose) and 0.6 g·min-1 of fructose (enriched with 13C fructose) directly before and every 15 min during exercise. Indirect calorimetry and isotope ratio mass spectrometry were used to calculate fat oxidation, total and exogenous carbohydrate oxidation, plasma glucose oxidation, and endogenous glucose oxidation derived from liver and muscle glycogen. Total carbohydrate oxidation during the exercise period was lower at altitude (157.7 ± 56.3 g) than sea level (286.5 ± 56.2 g, P = 0.006, ES = 2.28), whereas fat oxidation was higher at altitude (75.5 ± 26.8 g) than sea level (42.5 ± 21.3 g, P = 0.024, ES = 1.23). Peak exogenous carbohydrate oxidation was lower at altitude (1.13 ± 0.2 g·min-1) than sea level (1.42 ± 0.16 g·min-1, P = 0.034, ES = 1.33). There were no differences in rates, or absolute and relative contributions of plasma or liver glucose oxidation between conditions during the second hour of exercise. However, absolute and relative contributions of muscle glycogen during the second hour were lower at altitude (29.3 ± 28.9 g, 16.6 ± 15.2%) than sea level (78.7 ± 5.2 g (P = 0.008, ES = 1.71), 37.7 ± 13.0% (P = 0.016, ES = 1.45). Acute exposure to altitude reduces the reliance on muscle glycogen and increases fat oxidation during prolonged cycling in men compared with sea level.

Neural tube defects: Risk factors and preventive measures.

For the last 25 years, it has been proven that the occurrence or recurrence of neural tube defects can be prevented with the administration of folic acid before and early pregnancy. At present, over 80 countries in the world, except Japan, have mandated the fortification of wheat flour and/or rice with folic acid, which has resulted in a significant reduction in the prevalence of neural tube defects. In 2000, the Japanese government recommended folic acid 400 µg daily for young women of childbearing age and women who are planning to conceive. In 2002, the government started to present information about the importance of folic acid in the development of fetuses in the Mother-Child Health Booklet annually. Despite these endeavors, the prevalence of neural tube defects has remained unchanged. We discuss the risk factors of neural tube defects and propose preventive measures to decrease the number of neonates with neural tube defects. We believe that the government should implement the fortification of staple food with folic acid very soon, which will eventually decrease not only the neonatal mortality and morbidity, but also the economic burden on our health care system.

Evaluation of the implementation of the folate-neural tube defect health claim and its impact on the availability of folate-fortified food in Australia.

OBJECTIVE: To evaluate the implementation of the folate-neural tube defect (NTD) health claim and its impact on the availability of folate-fortified food in Australia. METHODS: During late 2005, a survey was conducted in 16 supermarkets across all Australian capital cities to identify the use of the folate-NTD health claim on the labels of the 128 food products listed in food standard 1.1A.2: 'Transitional standard--Health claims' and the number of products fortified with folic acid. RESULTS: Seventy-nine per cent of existing listed food products were found and two of these were implementing the folate-NTD health claim. Forty-four per cent of these listed products, previously fortified with folic acid, were no longer fortified. One hundred and seventeen generally available food products were fortified with folic acid, predominantly breakfast cereals (73%). Twenty-seven per cent of these folate-fortified products were listed in the transitional standard. CONCLUSIONS: The health claim was not used widely to inform women of child-bearing age of the importance of periconceptional folate intake. The increased availability of folate-fortified products generally has occurred independently of the health claim. Deficiencies in the verification system of the tested regulatory framework are identified. The voluntary regulatory provisions for both folate fortification and the use of the health claim diminished the States' influence over their implementation of public health tools.

Prevalence of Vitamin D deficiency in Pakistan and implications for the future.

BACKGROUND AND AIMS: vitamin D deficiency (25-hydroxyvitamin D) affects over one billion people worldwide. Vitamin D deficiency results in progression of osteoporosis as well as other conditions. Previous studies have shown high rates of vitamin D deficiency in Pakistan despite appreciable levels of sunshine. However, none have assessed vitamin D deficiency across all age groups, genders, incomes, and locations to guide future strategies. METHODS: Questionnaire and blood sampling among 4830 randomly selected citizens. RESULTS: High levels of deficiency among all age groups, genders, income levels, and locations. Amongst the selected citizens, 53.5% had vitamin D deficiency, 31.2% had insufficient vitamin D, and only 15.3% normal vitamin D. CONCLUSION: High rates of vitamin D deficiency in Pakistan despite high levels of sunshine and previous Food Acts asking for food fortification with vitamin D. Public health strategies are needed to address high deficiency rates, including food fortification, i.e. nurture, alongside increasing exposure to sunlight, i.e. nature. This will involve all key stakeholder groups.

Food patterns, flour fortification, and intakes of calcium and vitamin D: a longitudinal study of Danish adults.

STUDY OBJECTIVE: Deficiencies in calcium and vitamin D intakes are involved in the aetiology of osteoporosis, and health authorities recommend that the population consume a diet providing sufficient calcium and vitamin D. However, in 1987 the Danish Government withdrew a mandatory fortification of flour with calcium. This study examines intakes of calcium and vitamin D over time, in relation to food patterns, recommendations, and legislation. DESIGN: Food and nutrient intakes were measured by a short food frequency questionnaire (FFQ) and a thorough diet history interview, in 1987/88, and again six years later. SETTING: Copenhagen County, Denmark. PARTICIPANTS: 329 men and women, aged 35-65 years at first examination in 1987/88. RESULTS: At both examinations the non-enriched median intakes of calcium in men as well as women were above the recommended 600 mg/day. However, apparently the fortification of flour supplied up to 30% of the total calcium intake, and without the mandatory fortification, the percentage of adults with intakes below this recommendation increased from 6% to 22%. This group of subjects consumed cheese, milk, and oatmeal less often than those who had calcium intakes over 600 mg/day. During the study period the median intakes of vitamin D, which were well below the recommended 5 micrograms/day, did not change significantly. Associations between foods and vitamin D intakes were, in general, weak and insignificant, except for a positive association with fish intake. CONCLUSIONS: Data on calcium intakes suggest that the decision to stop the mandatory fortification of flour with calcium may have been premature. The short FFQ may be used for a rough classification of people in relation to their calcium intake, while this method seems insufficient for ranking vitamin D intakes.

Iodine prophylaxis programme in rural area of Kolhapur district of Maharashtra.

It is well established that iodine deficiency is the principle cause of goiter and widely prevalent nutritional problem in India. A great number of subjects living in iodine deficient conditions have appeared to develop adequate adaptive mechanism without clinical evidence of thyroid hyperplasia. Also govt. of India has implemented compulsory use of iodized salt all over the nation since 1985 as a prophylactic measure. But the programme is criticised through various channels of publications, stating that the long term consumption of iodised salt may result in toxic effects of iodine, such as thyrotoxicosis and other thyroid related complications. A survey was carried out therefore to study the effects of prophylaxis programme among the rural community of Kolhapur district of non-endemic area and ill-effects if any, due to prolonged use of iodised salt were studied. Our study concludes that use of iodised salt has beneficial effects towards prophylactic measures against goiter. Also prolonged consumption of iodised salt in non-endemic area has not resulted in any ill-effects due to extra iodine.
