(May 14) David Heber, director of the UCLA Center of Human Nutrition, recently presented new findings on the nutritional value of avocados to the California Avocado Commission's annual Nutrition Advisory Committee meeting in Santa Barbara, Calif., according to a news release.

Heber's research found that avocados contain twice as much vitamin E as previously believed, making avocados the best fruit source for vitamin E. This antioxidant is known to slow the aging process and protect against heart disease and several common forms of cancer by eliminating free radicals, which cause cell damage.

The study also showed that avocados are one of the highest fruit sources of lutein, a phytochemical that prevents against eye diseases such as cataracts and macular degeneration.
