Avocados May Prevent Oral Cancer,
Nutrients taken from avocados are able to thwart oral cancer cells, killing some and preventing pre-cancerous cells from developing into actual cancers, according to researchers at Ohio State University.
Studies have long associated the consumption of fruits and vegetables with a reduced risk for various types of human cancer. The protective effect is attributed to the high levels of phytonutrients or phytochemicals — plant compounds thought to have health-protecting qualities — that are often found in dark colored fruits and vegetables.
Avocados are chock-full of beneficial antioxidants and phytonutrients, including vitamin C, folate, vitamin E, fiber and unsaturated fats. They are naturally sodium-free, contain no trans fats and are low in saturated fat, making them a healthy addition to any diet.
Avocados are also rich in glutathione, a powerful antioxidant that attacks free radicals in the body by blocking intestinal absorption of certain fats. They also supply even more potassium than bananas and are a strong source of beta-carotene. Scientists believe that avocados may also be useful in treating viral hepatitis (a cause of liver cancer), as well as other sources of liver damage.
