Avocados contain nearly 20 vitamins and minerals, including vitamin C, vitamin E, potassium, and folic acid. They are rich in dietary fiber, and are known for being a good source of monounsaturated fat, second only to olives among fruits in oil content. Avocados have earned the nickname “nutrient-boosters” because they can enable the body to absorb more fat-soluble nutrients of other foods served in combination with the avocado.
