Like watermelon, pineapple is low in calories and has a high water content, so you can eat quite a lot of it. Shapiro likes to squeeze lime juice and sprinkle sea salt on top for a combo that promotes healthy digestion.
"Foods with a high water content keep us feeling full so we eat less, and few natural foods have more water than melon," says Ansel. One cup is around 90 percent water and has only about 45 calories. The addition of balsamic vinegar helps activate pepsin, a digestive enzyme that breaks down proteins into amino acids.
