The avocado tree is native to Mexico, and bears the avocado fruit. Technically, the fruit is a single large berry, which contains a large seed. The Inca, the Olmec and the Maya all cultivated avocado trees, and believed the fruit to be an aphrodisiac. Avocado is the main ingredient in guacamole.
Avocados are highly nutritious, being particularly rich in vitamin K, necessary for good bone health; and in B vitamins such as vitamin B5 and B6. The fruit is also an excellent source of folic acid and vitamin E.
There is more potassium in an avocado than in an equivalent weight of bananas. Potassium is essential for maintaining healthy electrical activity in the body, and many people don't get enough of this vital mineral.
Avocados are also very high in healthy fats, particularly oleic acid, which is known to help reduce inflammation in the body. These fats can also help the body to absorb nutrients from other food eaten at the same time as the avocado.
As part of a healthy diet, avocados can be eaten in many ways. Avocado supplements can be taken as a pill or capsule; avocado oil is also available, which can be used for cooking, taken internally or used in skin and hair care for its nourishing properties.
