19 Iron Zinc Vitamin B-6 Vitamin A Calcium Vitamin C In some areas the foods fed to children have a low energy density and children have difficulty consuming enough to meet their needs.

21 An internet search of Moringa and nutrition results in a large number of sites, some making extraordinary claims A lot of the information on the web is derived from just a few sources Some of the comparisons are based on 100 grams of food, which can be quite different from the amounts humans typically consume. Some of the comparisons are based on information from the early 1950 s, and the techniques for assessing the nutrient content of food have improves since then. A comparison of nutrient content based on a more typical portion sizes follows. This comparison reveals that Moringa leaf powder does provide significant amounts of some of the nutrients often lacking in human diets.
