Since 1961 in Zambia there has been a notable decline in the availability of milk, meat, eggs, and beans, and an increase in cassava and vegetable oils.
Adding livestock to poor households in developing countries such as Zambia is shown to improve their financial status, but how the addition of milk and meat to their diet effects their nutrition has not been studied.
This research finds that adding a small amount of milk and meat to the diet dramatically improves the supply of nutrients--specifically protein, calcium, zinc, iron, vitamin A, B2, B12, and D.
