Avocados
 

Avocados were once a luxury food reserved for the tables of royalty, but now avocados are enjoyed around the world by people from all walks of life.  Research published in the January 2005 issue of the Journal of Nutritional Biochemistry indicate that nutrients in avocados can work together to inhibit the growth of prostate cancer cells.

The analysis was conducted at UCLA where researchers discovered that avocados are the richest source of lutein among commonly eaten fruits. Lutein is a carotenoid that acts as an antioxidant and has been linked to a reduced risk of prostate cancer in previous studies.

According to Dr. David Heber, director of the UCLA Center for Human Nutrition, the study focused on inhibition of human prostate cancer cell growth when exposed to an extract of whole avocado fruit versus treatment with pure lutein. UCLA lab tests showed that when avocado extract was added to two types of prostate cancer cells, cell growth was inhibited by up to 60%, whereas purified lutein alone was ineffective. In other words, when a single nutrient, lutein, was extracted from avocados it did not offer the same anti-cancer results as the whole avocado extract.

Dr. Heber commented: "What's really exciting about this study is that the results indicate that the carotenoids, vitamins, and diverse compounds in avocados might have additive or synergistic effects against prostate cancer compared with pure lutein alone".

The moral of this story seems to be that whole foods, in their original whole form, offer the best nutrition possible for the human body

Prunes
 

Prunes are a good source of fiber and have long been recognized as a nutrient-rich fruit with multiple health benefits. But according to a recent study from Tufts University in Boston, prunes may also help slow the aging process in both the body and brain. The study ranked the antioxidant value of commonly eaten fruits and vegetables using an analysis called ORAC (Oxygen Radical Absorbency Capacity). Prunes topped the list with more than twice the antioxidant capacity as other high-scoring fruits such as blueberries and raisins.
 
ORAC is a test tube analysis that measures the total antioxidant power of foods and other chemical substances. Early findings suggest that this same antioxidant activity translates to animals, protecting cells and their components from oxidative damage.

"If these studies are borne out in further research, young and middle-aged people may be able to reduce their risk of diseases of aging - including senility - simply by adding high antioxidant foods to their diets," said Floyd P. Horn, administrator of the USDA's Agricultural Research Service, in Beltsville, Md.

The role of fruits and vegetables in health promotion and disease prevention may also be related to nutrients, other than the vitamins, minerals and fiber, found in these plant-based foods. In addition to well-known antioxidant vitamins A and C and beta-carotene, there are over 1,800 other biologically active compounds that have been identified in foods. Research is just beginning to identify these nutrients and to describe their activity in the human body; however, many are believed to offer the protective benefits of antioxidants.

At The Wholefood Farmacy, prunes can found in Phi Plus and DetoxiPhi, which are two of the most popular foods amongst the family of Wholefood Farmacy Wholesale Club Members.
