8. Grapes
Grapes are a delicious snack, but they contain a high level of fructose, which is frequently malabsorbed when eaten in large amounts. There are a couple of other elements in grapes that can cause digestive issues, too.
One is salicylates, which occur naturally in the skin of fruits as a form of defense against insects. If you are sensitive to salicylates, you may experience headache, rapid heartbeat, and anxiety when you eat grapes.
Another substance that can lead to nausea and cramps in some people are tannins. Tannins are polyphenols that are healthy for most people, but aggravate folks who are also sensitive to tannin-heavy things like green tea and wine.
