Acai Berry extract was added to human leukemia (HL60) cells. The higher the concentration of Acai the greater the inhibition of leukemia. The Acai inhibited the proliferation of leukemia cells by 56% to 86% depending on the amount used.

In aging there is an accumulation of damage to DNA and diverse deleterious changes in the cells that lead to increased risk of diseases. Damage by free radicals (the opposite of antioxidants) contributes to age-related damaging DNA protein cross-linkages in the brain and spinal chord (the central nervous system). Aged rats were compared to aged rats supplemented with Grape Seed Extract for 30 days.

Harvard scientists in conjunction with researchers from the University of Nottingham's Institute of clinical research have just finished a very interesting experiment examining the benefits of cocoa with the help of two populations of Kuna Indians. One group of Kuna's still lives on their ancestral home and drink large quantities of flavanol-rich Cocoa every day. The second group has migrated to a city and instead of drinking flavanol-rich Cocoa on a daily basis they drink a commercially processed cocoa that would therefore be much lower in Cocoa flavanols; these flavanols are lost during processing.

Humans (and some other primates) see color differences through an interaction between three types of color sensing cone cells located in the retina of the eye. It was found that giving individuals the carotenoids Lutein and Zeaxanthin not only improved the thickness of the macular tissue pigment but also improved the ability to discern the differences between the red and green spectrum of vision (but had no effect on yellow/blue). In this study it was found that Lutein and Zeaxanthin improve macular pigment density and improve color vision.

Blockage of a main artery leading to the heart (coronary artery) decreases the blood supply to the heart and decreases heart function; this ultimately leads to an enlarged heart and heart failure. During blockage of major arteries leading to the heart, the body actually produces collateral blood vessels to reestablish and maintain blood flow to the heart. These researchers and others have shown that the formation of these new small capillaries leading to the heart, a process called angiogenesis, protect the heart from a lack of oxygen and protect the heart muscle from cell death.
