Genetic taste sensitivity to the bitterness of 6-n-propylthiouracil (PROP) is a potential marker for food selection. Compared with non-tasters, PROP tasters, especially super-tasters, are less accepting of cruciferous and other green vegetables, bitter citrus, added fats and chili pepper. If super-tasters avoid these foods, it may be hypothesized that they ...
