Health Benefits of Avocados
Avocados earn their all-star rating by offering many health benefits. They are an excellent source of potassium, several B vitamins, vitamin E and fiber. One avocado contains as much potassium as two or three bananas. Potassium is an important mineral and electrolyte that helps enzymes involved in carbohydrate metabolism and is essential for heart contraction. In addition, studies suggest that for people with high blood pressure, diets high in potassium can help to lower blood pressure1.
In addition to potassium, avocados are great sources of dietary fiber and vitamin E. Dietary fiber can improve digestive health and bowel regularity. Vitamin E is a fat-soluble vitamin and a powerful antioxidant that protects the body from damaging free radicals1.
Not all Fats are Created Equal
Avocados can boast heart-healthy fat. Although all fats contain the same amount of calories, they affect the body very differently. Avocados are high in fat, but they contain the heart healthy monounsaturated fat. Diets higher in monounsaturated and polyunsaturated fats may decrease the risk of heart disease2.
Monounsaturated fats have also been shown to lower the “bad” LDL cholesterol and increase the “good” HDL cholesterol. The oils contained in avocados include oleic and linoleic acids. Studies show that those oils may help to lower cholesterol levels2.

History of Avocados
The avocado originated in south-central Mexico between 7,000 and 5,000 B.C. This wild avocado tree was not domesticated until several thousand years later. Domesticated avocado seeds have been found buried with Incan mummies dating back to 750 B.C. and avocados may have been cultivated in Mexico around 500 B.C. Spanish conquistadores in central America could not pronounce the Aztec word ahuacatl, so they changed it to aguacate. Sir Henry Sloan first mentioned the avocado by its English spelling in 1696.
Where are Avocados Grown?
The avocado tree can only grow in tropical and subtropical climates. Most of the world’s avocados are grown in the United States (California and Florida), Mexico, Dominican Republic, Brazil and Columbia. California produces about 90% of the avocado crop in the United States. A single avocado tree in California can produce up to 500 avocados each year.
Avocado can be used as a spread on sandwiches and toast or slices can be added to a salad or burrito. Avocado is the base ingredient for guacamole – a mashed avocado dip that originated in Mexico.
A ripe avocado is slightly soft, but with no dark sunken spots or cracks. A firmer, less mature fruit can be ripened at home and will be less likely to have bruises.
One serving of avocado is 1 ounce or about 1/5 of a medium avocado.
