Avocados are highly nutritious and contain about 20 different vitamins and minerals per serving, according to WebMD. They are high in infection- and disease-fighting B vitamins and also contain a healthy amount of vitamin E and vitamin C, which are believed to have cancer-preventing qualities.
Avocados also contain fiber, are low in sugar and are high in healthy monounsaturated fats, which are helpful in lowering bad cholesterol. Even though avocados are nutritious, they are high in calories, so they should be eaten in moderation. In order to gain the full benefits from avocados, it is important to store them at room temperature, wash them thoroughly and only eat them when they are fully ripened.
