Avocado
It is a powerful antioxidant and a strong source of phytochemicals - betacarotene, vitamin C, folate, vitamin E and unsaturated fats. Recent studies (2007) at the Ohio State University, says that extracts from Hass avocados could kill oral cancer cells as well as arrest their growth. The phytochemicals present in avocado either kill the pre-cancerous cells or stop the growth of pre-cancerous cells in the body without affecting normal cells.
Avocados provide nearly 20 essential nutrients, including fiber, potassium, Vitamin E, B-vitamins and folic acid. They also act as a "nutrient booster" by enabling the body to absorb more fat-soluble nutrients, such as alpha and beta-carotene and lutein, in foods that are eaten with the fruit
Avocados and Cardiovascular Disease
Cardiovascular disease is the leading cause of death in the United States, but a healthy diet and exercise plan may help reduce your risk of developing the life-threatening illness.
The American Heart Association (AHA) Dietary Guidelines recommend a diet that has at least five servings of fruits and vegetables, contains up to 30% of calories from fats (primarily unsaturated) and is low in saturated fat, cholesterol, trans fats and sodium while being rich in potassium. Avocados can help you meet the AHA dietary guidelines because they have both monosaturated and polyunsaturated fat and contain potassium.
