Dark green, leafy vegetables enhances vitamin A in Children

A randomized, double-blind, controlled study was conducted to determine whether the consumption of leafy vegetables by preschool children would enhance their serum vitamin A concentration to acceptable levels.

The importance of these findings in alleviating and/or controlling vitamin A deficiency in developing countries is discussed.

Preschool children in Saboba, northern Ghana, were randomly assigned to five feeding groups, differing essentially in the amount of fat and beta-carotene, fed once per day, 7 days per week, for 3 months.

The consumption of dark green, leafy vegetables (with fat- 10 g/100 g) significantly enhanced serum retinol; consequently, the percentage of children with adequate retinol status increased from after feeding.

Dark green leafy vegetables are good sources of many vitamins and minerals your body needs to stay healthy, such as vitamins A, C, and K, folate, iron and calcium. They are also great sources of fiber. Research suggests that the nutrients found in dark green vegetables may prevent certain types of cancers and promote heart health. It is recommended that teenage girls eat 3 cups of dark green vegetables per week, or about ½ a cup every day.

Dark Green Leafy Vegetables

Dark green vegetables are also high in fat-soluble vitamins such as vitamins A, K, D, and E. These vitamins require a little bit of dietary fat in order for the body to absorb them. When you eat dark green vegetables, make sure to add a teaspoon of dietary fat, such as flax oil, olive or sunflower oil, avocado or seeds and nuts to make sure your body absorbs all of the vitamins you eat.
