Grapes, especially red varieties, contain several beneficial plant compounds. The one you’ve probably heard about is resveratrol, otherwise known as a great excuse to drink red wine. Resveratrol helps the liver by reducing inflammation and protecting against damage by free radicals. Regular consumption is thought to lower your risk of developing cancer, too.
A small research study in people with non-alcoholic fatty liver disease (NAFLD) indicated that daily consumption of grape seed extract over three months improved their liver function. Of course, grape seed extract is way more concentrated than what you’d get in whole grapes, or wine for that matter.
