Fat and energy needs of children in developing countries

Area of Science:

• Nutritional Science
• Pediatric Nutrition
• Global Health

Background:

• Childhood fat requirements are determined by metabolic fuel needs, energy density, essential fatty acids, and fat-soluble vitamin absorption.
• While similar to affluent nations, developing countries face additional fat needs due to environmental stresses like recurrent infections.
• Low energy density of weaning foods is a significant factor in growth faltering and malnutrition in developing nations.

Purpose of the Study:

• To compare fat intake and requirements in children from developing and affluent countries.
• To investigate the impact of weaning practices on fat intake and nutritional status.
• To highlight the challenges in meeting children's fat needs in resource-limited settings.

Main Methods:

• Comparative dietary analysis using data from rural The Gambia and Cambridge, UK.
• Review of evidence from doubly labeled water studies on diet adequacy during illness and recovery.
• Assessment of fat and essential fatty acid contributions from breast milk, weaning, and adult foods.

Main Results:

• Breast milk is a crucial source of fat and essential fatty acids for Gambian children up to two years old.
• Weaning and adult foods in The Gambia are low in fat, leading to a sharp decline in intake post-weaning.
• Diets adequate for healthy children in developing countries may not support catch-up growth after infections.

Conclusions:

• Low fat intake after weaning is a critical issue for children in developing countries, potentially impacting growth and recovery.
• The transition from breast milk to low-fat complementary foods requires further study regarding its long-term effects.
• Investigating the impact of low fat intake on immune function in these populations is essential.
