Avocados are a cholesterol-free, sodium-free, low saturated fat food with only 5.0 grams of fat per serving - a level usually acceptable for inclusion in a low fat diet. In fact, most of the fat found in an avocado is monosaturated, believed by some scientists to protect against heart disease and certain kinds of cancer.

Further, avocados are "nutrient dense" in that they supply more of your daily nutrient requirements for fewer calories spent. Avocados are nutrient dense in potassium, folate, dietary fiber, vitamin C, vitamin E, riboflavin and vitamin B6.
