Grapefruit
Grapefruit is high in antioxidants, which protect the liver naturally. Naringenin and naringin are the two primary antioxidants found in grapefruit. Both have been shown in animal studies to help protect the liver from injury. Grapefruit has been shown to have two defensive properties: it reduces inflammation and protects cells. These antioxidants have also been shown to aid in the prevention of hepatic fibrosis, a dangerous disease in which excessive connective tissue grows up in the liver. Chronic inflammation is usually the cause.
Furthermore, in mice fed a high-fat diet, naringenin reduced the amount of fat in the liver and increased the number of fat-burning enzymes, which may help prevent the accumulation of excess fat. Finally, naringin has been demonstrated to increase the ability to metabolize alcohol and counteract some of the negative effects of alcohol in rats. Recent data also suggests that grapefruit can help maintain your liver healthy by preventing damage and inflammation.
