Pottenger's Cats: Study found that poor diet will affect future generations

In the 1930s, Dr. Francis Marion Pottenger, Jr., a physician in Monrovia, California, worked at the Pottenger Sanatorium and Clinic, a center founded by his father and two uncles, that specialized in tuberculosis (TB). Pottenger hypothesized that tuberculosis was caused by deficiencies in the adrenal gland, and he used cats in the process of standardizing the potency of the adrenal extracts with which he was treating patients. Pottenger fed cats both cooked and raw meat. To his astonishment, he observed very different health outcomes. Out of curiosity, Pottenger began a ten-year study focused on variations in the diets of cats. The variables in his experiments included either raw milk versus cooked or raw meat versus cooked. Throughout the entire study and four generations of cats, Pottenger diligently recorded his observations of the health, weight, calcium and phosphorus levels, skeletal structures, and dispositions of the cats. The differences were quite striking.
