Avocados are considered to be healthy foods because they are nutrient-dense, containing almost 20 vitamins and minerals, including folate, vitamin B, Vitamin E and potassium. The fruits are also high in fiber and healthy fats and low in sugar.
Avocados have more potassium than bananas; a medium avocado has 14 percent of the recommended daily allowance of potassium versus the 10 percent provided by a medium banana. Additionally, a medium-sized avocado contains 7 grams of fiber.
Although avocados have no cholesterol, sodium or saturated fat, they contain high amounts of monounsaturated fat, which helps to lower bad cholesterol. Moreover, the fat content helps the body to absorb fat-soluble vitamins, such as vitamins E and K, more readily. This makes avocados a heart-healthy option when eaten in moderation and in combination with other nutrient-rich foods.
Avocados also provide health benefits that target cancer cells and may help to improve arthritis, according to Mercola.com. Avocados further offer a friendly food option to individuals trying to lose weight. The high fiber content helps people who eat avocados to feel more satisfied and less hungry over time.
A single serving of avocado is equal to one-fifth of a medium avocado and contains approximately 50 calories.
