Having spent many years in Africa, I have to agree.
In most parts of Africa they have stripped the habitat of game animals to the point that they have very little protein in their diets.
That's the reason you see so many pictures of little pot-bellied African children - they survive on a high carbohydrate diet of yams.
In most villages along the rivers there are a few avacado trees that belong to the village, and the fruit is harvested communally.
These trees are huge, and they provide the only dependable source of protein.
That and maize. But if it's used for making pomba beer, there's no mealie meal for the kids, as is often the case.
