Prebiotic Contents in Indian Food at NIN (2017- 2018)

This is a study of prebiotic content of Indian foods using NIN database.


Optimal Vitamin D Supplementation Strategies for Vitamin D Deficient Boys
With Type 4 & 5 Skin (2016-2018)

This study evaluated the optimal daily dose of vitamin D in Indian children 9-15 years of age with type 4 & 5 skin. It estimated the vitamin D content of commonly consumed foods by Indians and studied the nutritional status of healthy school going children with regard to intake of calcium, vitamin D and other micronutrients. This study concluded that vitamin D deficient children seem to benefit maximum with the daily dose of 2000 IU/day with 95% achieving serum levels of ≥ 20ng/ml following supplementation.


Midlife Factors that Influence the Aging Process: An Indian Perspective (2015- 2017)

Increasing number of oldest old worldwide has made human longevity a major area of scientific research. It is a well-established fact that the health of an individual and the population in general are the result of interactions between genetics and a number of environmental factors; nutrition and physical activity being of major importance. The Asian Indian phenotype predisposes Indians to NCDs, more so at an earlier age. Indian diets are in a state of transition with increasing amounts of refined carbohydrates and fats being consumed. Physical activity levels are markedly low. Concomitantly, a sharp rise in the prevalence of non-communicable diseases (NCDs) like diabetes, hypertension, cardiovascular diseases and cancers has been observed. Although some of the physiological changes experienced by older adults occur primarily as a result of the biological process of aging, lifestyle factors – such as diet and physical activity – are important modulators of the risk factors associated with chronic disease and even age related decline. Most NCDs have shared risk factors (tobacco use, unhealthy diet, physical inactivity, alcohol use) and integrated interventions targeting these risks from middle age will not only help to prevent and control NCDs, but also ensure a good quality of life in advancing years.


Under this study information was collected on broad profile of people 60 years and above. Factors contributing to healthy vs. pathological aging in India were identified. The study is a review of published articles and government reports. 273 articles and reports have been studied.


The Report includes following components:

  • Demography of ageing in India; concepts of ageing;
  • Health and morbidity status of Indian elderly; nutritional status, physical activity and lifestyle  of Indian elderly;
  • Midlife factors that influence the ageing process: the Asian Indian phenotype, non- communicable diseases, intrauterine and perinatal nutrition, physical activity, overweight/obesity, dyslipidaemia;
  • Best practices that promote healthy and successful ageing and
  • Identification of  gaps, research and policy needs for India to achieve healthy and successful ageing

The study has been published in the Journal of Aging Research & Clinical Practice.


Evaluation of UV Index in Different Regions in India (2013- 2015)

This study revealed that the peak UV-B radiation was between 11 AM and 1 PM in all the 7 different zones of the country; South (Madurai), North (Delhi, Leh), East (Guwahati), West (Pune and Goa) and Central (Hyderabad). The maximum UV irradiation was recorded during monsoon/autumn season suggesting role of pollution in blocking adequate UV-B rays reaching the earth surface. There was no increase in the serum 25(OH) D levels following sun exposure for one month in winter necessitating the need for vitamin D supplementation during these months.


Survey on Nutrition Labeling and Health Claims in
India, Bangladesh, Nepal and Sri Lanka (2013- 2014)

The survey looked at the current regulations on nutrition labelling and health claims in South Asian Countries.


Growth Velocity Reference Standards in Healthy School Going Children Aged 5-16 years (2012- 2014)

This study reports, for the first time in India, normative centile charts for height, weight and annual height velocity of apparently healthy school children in the age group of 4-17 years from northern India. This will help in   early detection, timely investigation and treatment of children with short stature and poor growth velocity.


The Effect of A Short Term Lysine Supplementation in Improving
Muscle Strength in Pre-Pubertal Indian Girls (2013)

The purpose of this study was to evaluate the effect of a short term lysine supplementation in improving muscle strength in pre-pubertal Indian girls. The researchers have concluded that the supplementation increased the lysine score from 45mg/g to 74mg/g protein / day in the experimental arm. There was significant increase in the non-dominant muscle strength in the lysine supplemented group compared to control group. This was independent of the haemoglobin status. There was an increase in height also in the lysine supplemented group although it was not significant.


Impact of Vitamin D Fortified Milk Supplementation on Vitamin D Status of Healthy
School Children Aged 10-14 Years (2011 – 2012)

The study was conducted in Delhi schools.  Primary objective of the study was to investigate the impact of vitamin D fortified milk on serum 25(OH) D levels. Primary outcome measure included: changes in vitamin D status as measured by serum 25 (OH) D levels. The study concluded that supplementing milk fortified with vitamin D is an effective and safe method of addressing the major public health issue of vitamin D deficiency in children. The study has been published in the International Journal of Osteoporosis.


Exploratory Study on Need and Feasibility of a Food Fortification Intervention in the
Mid-Day School Meal Programme in North Karnataka (2012)

This study assessed the quantity of specific macro and micronutrients (protein quantity and quality, iron) supplied to school children under the mid-day school meals scheme in Northern Karnataka. It also looked at the processes involved in mid-day school meal programme such as distribution of food grains, food preparation and transport, distribution of cooked food to school children, intake of food by children, wastage and financing mechanisms.
