There is no intrinsic reason African countries should be importing, rather than exporting, basic staples like rice or higher value products like frozen chicken, cooking oil, or instant noodles.
Sweetcorn, mushy peas, beans, lentils, are all basic staples that can be thrown together into a variety of surprising meals.
I was raised almost entirely on turnips and potatoes, but I think that the turnips had more to do with the effect than the potatoes.
Most of us cannot afford to store a year's supply of luxury items, but find it more practical to store staples that might keep us from starving in case of emergency.
If we went back to the basics of vegetables, legumes, grains - the things closer to the Earth - it's a lot better for the Earth and for other people. We can feed more people, we can feed the starving people.
