Standard. American. Diet. It's no coincidence the acronym is S.A.D. - "The standard American diet rates 11 out of 100. According to estimates from the U.S. Department of Agriculture, 32% of our calories comes from animal foods, 57% comes from processed plant foods and only 11% comes from whole grains, beans, fruits, vegetables, and nuts. That means on a scale of 1-10, the American diet would rate about a 1." (Greger 6) Sad, indeed.
