    Enriching diets for childhood mental and physical development
    (AOSIS OpenJournals, 2001) Kruger, H. S.; Labadarios, D. L.; Dhansay, M. A.
    Malnutrition is a public health problem in South Africa, especially among rural black children. Intakes below 67% of the Recommended Dietary Allowance (RDA) are common for calcium, iron, zinc, selenium, vitamin A, C, D, E, riboflavin, niacin and vitamin B6. Key nutrients for growth and development include calcium, iron, zinc, vitamin A, folate and other B-vitamins. Calcium is essential for bone mineralisation during the adolescent growth spurt. Iron deficiency is associated with impaired growth, delayed psychomotor development and impaired immunity. Zinc is associated with normal growth, bone mineralisation and neuropsychological function. Vitamin A is essential for normal growth, eyesight and immunity. Folate is necessary for the development of new cells, especially during phases of accelerated growth. Other B-vitamins are linked to a variety of behavioural and cognitive outcomes. Factors compromising the nutritional status of children include amongst others, an inadequate nutrient intake due to poverty, inadequate nutrition education, diarrhoeal diseases, teenage dieting and allergies. To ensure optimal growth and development, strict diets should be discouraged and sound meal patterns should be encouraged, including starting the day with breakfast, and eating a variety of foods to ensure adequate intakes of nutrients and fibre. Regular physical activity promotes a healthy body weight and normal bone mineralisation.
