| Quality Protein Maize (QPM) is an affordable option for alleviating protein malnutrition and reducing animal feed costs. QPM looks and tastes the same as normal maize but contains higher levels of the essential amino acids lysine and tryptophan. Eating QPM is especially beneficial for children who survive on a maize-dominated diet. |
