想問牛油果(水果)有甚麼益處?

The fruit of horticultural cultivars ranges from more or less round to egg or pear-shaped, typically the size of a temperate-zone pear or larger, on the outside bright green to green-brown (or almost black) in color. The fruit has a markedly higher fat content than most other fruits, mostly monounsaturated fat. A whole medium avocado contains approximately 15% of the United States FDA's recommended daily amount of saturated fat. Avocados also have 60% more potassium than bananas. They are also rich in B vitamins, as well as vitamin E, vitamin K, and folate.[4] A ripe avocado will yield to a gentle pressure when held in the palm of the hand and squeezed. The flesh is typically greenish yellow to golden yellow when ripe. The flesh oxidizes and turns brown quickly after exposure to air. To prevent this, lime or lemon juice can be added to avocados after they are peeled. The avocado is very popular in vegetarian cuisine, making an excellent substitute for meats in sandwiches and salads because of its high fat content. The fruit is not sweet, but fatty, strongly flavored, and of smooth, almost creamy texture. It is used as the base for the Mexican dip known as guacamole, as well as a filling for several kinds of sushi, including California rolls. Avocado is popular in chicken dishes and as a spread on toast, served with salt and pepper. In Brazil, Vietnam, and Taiwan, avocados are frequently used for milk-shakes and occasionally added to ice cream. In the Philippines, Jamaica and Indonesia, a dessert drink is made with sugar, milk, and pureed avocado. In Central America, avocados are served mixed with white rice. The fruit is also pressed for avocado oil production. In Chile, it is often used in hamburgers, hot dogs and celery salads. Avocado flesh has also been used by some Native American tribes in the Southwestern United States in the mixing and application of adobe, a natural building material[citation needed].

Avocado is also thought to promote physical beauty and is used in cosmetics to this day. The Aztecs ate the fruit as an aphrodisiac.
