Bill Bryson Corn Quotations

Out of the thirty thousand types of edible plants thought to exist on Earth, just eleven—corn, rice, wheat, potatoes, cassava, sorghum, millet, beans, barley, rye, and oats—account for 93 percent of all that humans eat, and every one of them was first cultivated by our Neolithic ancestors.

The human diet consists of just nine plants: corn, rice, wheat, potatoes, cassava, sorghum, millet, beans, barley, rye and oats.
