Is the green veggie powder craze hype or good for health?
Research from Ghana just published in June wanted to study the effects of giving greens powder made from green leafy vegetables to children. This was especially important in Ghana where anemia and vitamin-A deficiency are common health issues. The adverse effects of not getting enough are even worse during dry seasons when green vegetables, rich-sources of iron and vitamin-A, are scarce in that country.
Researchers were trying to find something that could be readily shipped, non-perishable and easy to give to kids that would keep them healthy.
For three months, children four to nine years old with deficiencies in vitamin A and iron received nutrient-dense dehydrated green vegetables each day. Although during the first couple of months there was no significant difference in the kids who did take the powder to those who didn’t, at the end of the study those who had received it increased their red blood cell mineral content (showing reduced anemia) and retinol concentrations (vitamin A) over 12%. This is considered a significant difference especially just three months after taking a minimal amount of the greens.
What about kids in Canada and the US that don’t get enough veggies in their diet? It can be assumed that greens powders would benefit them in a similar way to children in underdeveloped countries.
