Avocados act as ‘Nutrient Booster’- research
Allow the body to absorb significantly more heart-healthy and cancer-fighting nutrients like alpha-carotene, beta-carotene and lycopene found in fruits and vegetables.
04/03/05 Research findings published in this month's issue of the Journal of Nutrition indicate that avocados act as a "nutrient booster," allowing the body to absorb significantly more heart-healthy and cancer-fighting nutrients like alpha-carotene, beta-carotene and lycopene found in fruits and vegetables.
The study was conducted at Ohio State University where adult men and women consumed salad and salsa with and without fresh avocado. The subjects who consumed the meals with 75 grams of avocado (equivalent to 2.5 tablespoons) absorbed 8.3 times more alpha-carotene and 13.6 times more beta-carotene, both of which may help protect against cancer and heart disease. The subjects also absorbed 4.3 times more lutein, which contributes to eye health and may protect against macular degeneration, the leading cause of blindness in the elderly.
The subjects who consumed salsa with 150 grams of avocado absorbed 4.4 times more lycopene, which has been linked to prostate cancer protection, while absorption of beta-carotene doubled. Researchers concluded that the monounsaturated fat in the avocados boosted the participants' ability to absorb the beneficial nutrients.
According to Dr. Steven Schwartz from Ohio State University: "Many fruits and vegetables are rich in beneficial carotenoids, but most fruits and vegetables are virtually fat-free, which may limit the body's ability to absorb some of these nutrients. Our latest research shows that the natural fat content in avocados increases carotenoid absorption, which offers nutritional advantages over other sources of fat such as salad dressings."
Ounce-per-ounce, avocados rank highest in monounsaturated fat, vitamin E, folate, potassium, magnesium, lutein, beta-sitosterol and glutathione, compared to other commonly eaten fruits. According to the Food and Drug Administration, diets rich in fruits and vegetables may reduce the risk of some types of cancer and other chronic diseases. California avocados are a part of the National Cancer Institute's National 5 A Day program.
