"Seventy-five percent of the U.S. avocado crop is made up of Haas avocados grown in California. These are the avocados most people in the U.S. are familiar with and are, most likely, the only variety they can even name. But, it turns out there are other varieties of avocados – and one of them even has half the fat of a Haas avocado.
Fuerte avocados are grown in Florida and are actually larger than Haas avocados. Traditional Haas avocados have about 22 ½ grams of fat and 250 calories. The Fuerte varieties have only about 11 grams of fat and 125 calories.
Additional varieties of avocados include Zutano, Bacon and Cocktail. The Cocktail avocados are only one or two ounces each and do not contain the pit found in most other varieties."
