People who are especially sensitive to bitter compounds in broccoli and other foods tend to be thinner than others.

A Rutgers University study of nearly 50 women in their 40s, found that supertasters were 20% thinner than those not sensitive to bitter tastes. They generally perceive sweet, sour, salty, and bitter, more intensely and generally have more papillae, the parts of the tongue holding taste buds.

Supertasters appear to eat less food overall, and on average have a lower body mass index than non-tasters, who tend to like fattier, sweeter, hotter and more bitter foods, leading to higher body weights.

An earlier Rutgers study revealed that non-taster preschoolers preferred full-fat milk and ate more added fats such as butter and salad dressing.
