In low- and middle-income countries (LMICs), malnutrition is widespread, especially among women and children. Direct or immediate causes of malnutrition include malnutrition and disease, leading to poor growth, micronutrient deficiency and death. At least 45% of children under 5 years of age in LMS are malnourished.

Dietary-oriented agricultural policies and interventions that improve the availability and accessibility of nutritious foods, as well as family, community and national income generation potential, can be a gateway to addressing malnutrition. A variety of diets based on the consumption of traditional and local foods can not only ensure adequate nutrition and biodiversity safety, but also prevent unintended, health consequences. However, there is insufficient evidence of nutritional impact on food-vulnerable agricultural interventions.

General purpose

To provide evidence for stable isotope techniques to define and evaluate the role of balanced agro-food systems in health and nutrition.

Participating in the IAEA Integrated Research Project (CRP E43029), researchers from Africa, Asia, Latin America, Europe and North America explored the contribution of various agro-diets to health and nutrition in Bangladesh, Cuba, Haiti, and Myanmar. , Peru, Senegal and Tanzania United Nations.

Specific purposes

  1. To better understand the impact of agricultural diversity on nutrition, to evaluate the role of stable isotope techniques
  2. Evaluate the role of stable isotope techniques in raising awareness of unintended, dietary changes or changes in dietary intake.
  3. Evaluate the role of stable isotope techniques to better understand the effects of dietary-based agricultural interventions aimed at improving nutritional quality.
  4. To better understand the link between body composition and dietary differences, food frequency, and other dietary intake and quality indicators

Diet was the first indicator of nutritional status and was evaluated using a non-invasive stable isotope technique called detoxification dialysis.


A community-based community-based project involving ethical education and poultry and crops such as oranges, oranges, oranges, fruits and vegetables has been carried out in three Senegalese villages. Social, economic, dietary and health data were collected through questionnaires; Dietary status was assessed by anthropometry and body composition and low mineral content (vitamin A and iron). Dietary differences were assessed using the MDD-W tool, a small food gap developed by the Food and Agriculture Organization of the United Nations (FAO). CRP provides an opportunity to implement MDD-W in a diverse population.

A joint team of Mexican and Haitian researchers has examined the effectiveness of the Food Security and Nutrition Program in rural Haiti, focusing on vitamin A and iron levels in mothers and children. Researchers in Senegal and Haiti found improved iron and vitamin A levels among mothers produced under CRP. In Senegal, children who ate a lot of different foods had more fat deposits during the intervention period.

Introducing high-quality paddy rice seeds, fertilizers and houseplants A long-term study was conducted in Myanmar to compare infant nutrition, which includes home-grown food before agricultural intervention. In Peru, children between the ages of 6 and 72 have been assessed for nutritional benefits associated with a sustainable agricultural program that can produce mineral and vitamin-rich vegetables along with iron supplements.

In general, and unexpectedly, there were no significant differences in diet and body composition between mothers and children who received intervention. This is partly due to the fact that malnutrition, low-intensity and short-term agricultural interventions are not statistically significant. The complex and indirect nature of agri-food interventions limits any visible impact.

The body composition information generated by CRP may contribute to the future of the global database. The simplest methods for measuring body composition and blood retinol are also proven in CRP, which promotes academic training at the undergraduate and postgraduate levels and between countries.


Deuterium dilution, non-invasive stable isotope technique

An indicator of changes related to dreaming (malnutrition, obesity and obesity), a stable system for evaluating body composition, ie body fat and fat without fat. Deuterium depletion is a method of assessing body composition and the impact of altered diet and exercise on the risk of dementia.

One drinks balanced water with deuterium, a stable hydrogen isotope. The water is non-radioactive and has no serious health consequences. After a few hours, the isotope is evenly distributed throughout the body, which may be in the form of saliva or urine. The enrichment of Deuterium in saliva is measured using a Fourier transform infrared spectrophotometer (FTIR) or isotope ratio mass spectrometer (IRMS). Since the amount of diuretic is known, the total amount of water can be calculated from enrichment. Based on the assumption that fat is free of water, scientists can accurately determine the ratio of fat to fat-free tissues. This nuclear technique is accurate and safe to use in all age groups; It is not associated with any radiation hazards and is suitable for use in field settings.
