New study says Orange Maize improves Vitamin A in children

The latest study by the American Journal of Clinical Nutrition (AJCN)  has established that ‘orange’ vitamin A maize increases vitamin A storage in the body, NaijaAgroNet Reports.

This maize, NaijaAgroNet gathered has been orthodoxly bred as non- Genetically Modified Organisms (GMOs) to have higher levels of beta-carotene, a naturally occurring plant pigment that the body then converts into vitamin A.

Experts from AJCN affirmed to NaijaAgroNet that lack of sufficient vitamin A blinds up to 500,000 children annually and increases the risk of death from disease (such as diarrhea in children). Thus, Vitamin A deficiency is widely prevalent in Sub-Saharan Africa.

NaijaAgroNet also gathered that foods that are good sources of vitamin A, such as orange fruits, dark leafy vegetables, or meat, are not always available, or where they are they could be too expensive in some regions. 

Just as in many African countries, people eat large amounts of staple foods like cassava or maize. 

The efficacy study,  NaijaAgroNet learnt revealed that children from the Eastern Province of Zambia were randomly assigned to three feeding groups and received either white maize, orange maize, or a daily vitamin A supplement. After three months, both groups that received either the orange maize or vitamin A supplements showed significant increases in their total body stores of vitamin A, with no changes observed in the group that received white maize. 

Lead scientist Sherry Tanumihardjo said “we were surprised to find that most of the children in this study already had substantial stores of vitamin A. We attribute this to the success of fortifying sugar with vitamin A, the provision of vitamin A supplements to young children, and perhaps better diets. Yet, despite having adequate vitamin A stores, we still saw this store increase in children as a result of eating the orange maize. So, I’m confident that orange maize would be especially effective in increasing body stores of vitamin A in populations suffering from vitamin A deficiency.” 

Unlike the form of vitamin A found in supplements and fortified foods, Sherry said, the body regulates conversion of beta-carotene into vitamin A, and consuming high levels of beta-carotene is not harmful to health. 

Additionally, Sherry said several orange maize varieties have been released by the governments of Zambia and Nigeria. 

HarvestPlus Country Manager for Zambia, Eliab Simpungwe, stated in a press statement made available to NaijaAgroNet that in Zambia, they provided orange maize to more than 10,000 farming households and is now working with the private sector with the goal of reaching 100,000 farmers by 2015. 

“The orange maize has been embraced by consumers once they have had a chance to taste it. When they also understand the benefits of vitamin A in the diets they are all the more enthusiastic about orange maize”  Simpungwe said.

Pointing out that the orange maize varieties released are also high yielding, disease and virus resistant, and drought tolerant. 

The Zambian Government has officially recognized biofortification, which it includes in the National Food and Nutrition Strategic Plan for Zambia 2011-2015. 

Additionally, the Acting Executive Director of the National Food and Nutrition Commission in Zambia, Musonda Mofu, who was also on the study team, said “there are still many pockets where vitamin A deficiency remains a problem in Zambia. 

"Food-based approaches such as orange maize can provide people—especially women and children—with a good portion of their daily vitamin A needs through nshima or other traditional foods made from maize, that we Zambians eat every day. For us, this is cost-effective and a safe approach to improving nutrition,”  Mofu assured.
