3. Grapes
Like berries, grapes contain fiber and antioxidants. Specifically, grapes contain an antioxidant called resveratrol, which may help prevent further liver damage in people with NAFLD. Studies show that people with NAFLD who take resveratrol supplements made from grape extract may have less inflammation.

Studies show that these compounds, including catechins, can also help lower the risk of NAFLD. Green tea catechins may also help prevent liver cancer.
