Cognitive Health creased following the oral administration of grape seed extract. Similar studies on other favonoids—including epigallocatechin gallate (EGCG) from green tea, favanones from citrus and tomatoes, favonols from Ginkgo biloba, and anthocyanins from berries—show that these compounds also penetrate brain tissue (Free Radical Biology & Medicine, 2012). In addition to crossing the blood-brain barrier, studies indicate that favonoids actually accumulate in areas of the brain that are critical for neural functioning and memory, and areas that play a role in pathological processes associated with dementia and other diseases. Tis is a critical aspect of their ability to confer biological efects. As an example, Cristina Andrés-Lacueva and colleagues from the University of Barcelona and the USDA Human Nutrition Research Center on Aging at Tufts University found that the administration of blueberries to rats led to detection of anthocyanins in the cerebellum, cortex, hippocampus, and striatum of the brain (Nutritional Neuroscience, 2005). Mechanisms for Brain Support In the context of Alzheimer's disease, Robert Williams from the University of Bath, and Jeremy Spencer from the University of Reading in the United Kingdom, authored a review summarizing the potential therapeutic utility of favonoids for cognitive function and dementia (Free Radical Biology & Medicine, 2012). While conventional wisdom regarding the biological activity of favonoids centers on their direct antioxidant potential, the authors proposed that antioxidant activity is not the primary mechanism of favonoid benefts to the central nervous system; Solutions for Healthy Aging. Zinc. Magnesium. Selenium. These minerals contribute to brain and nervous system health and psychological functions. But the human body needs proper absorption of these vital nutrients to gain their benefits. We have the solution.

Brain-Cell Signaling Research on the interactions between favonoids and brain cells reveals that native favonoids and their intestinal metabolic byproducts actively bind to neurons. Several favonoid binding sites have been discovered on brain cells, while a specifc binding SEPTEMBER 2013 ■ NUTRITIONAL OUTLOOK ES315725_NO1309_036.pgs 09.04.2013 04:16 UBM
