Blueberry Juice Enhance Memory »

You’ll likely be hearing (if not already) juice makers and berry growers tout the benefits of blueberry juice on memory. For the first time researchers have shown that a few daily glasses of blueberry juice can boost memory in older adults with early signs of memory loss. Blueberries, like tomatoes, grapes and tea, contain polyphenols which are known to have antioxidant and anti-inflammatory properties. Therefore, it’s theorized that these substances can combat oxidative stresses that can lead to cardiovascular and neurodegenerative diseases. The recent study is published in the current issue of the American Chemical Society’s Journal of Agricultural and Food Chemistry. However, it must be noted that the researchers only studied a total of 18 patients – 9 were given blueberry juice and 9 given placebo – making this an extremely small study which may not necessarily extrapolate to an entire population of people. Therefore, the jury is still out on this one. Although drinking blueberry juice will likely not worsen your memory, there are other means that have been shown to slow memory loss, including keeping mentally active, exercise, cultivating a strong social network, stopping smoking, and getting plenty of sleep.

Red Wine Spills Its Secrets »

How many times have you heard that red wine is good for your health? We know that polyphenols (powerful antioxidants that are believed to be protective against cancer and heart disease) are abundant in red wine. But how they exert their beneficial influence was a mystery – until now. New research led by Dr. Joseph Kanner of the Hebrew University of Jerusalem has shown that polyphenols can act inside the stomach to reduce the formation of malondialdehyde, toxic byproducts produced during digestion of meats and high-fat foods. Based on these results, Dr Kanner and his colleagues argue that previous research looking for antioxidants from wine in the bloodstream was a mistake. They do not need to be in the blood to be useful. They just need to be in the stomach at the time the toxic metabolites are produced. Therefore, they recommend drinking wine with your meals. Their research also suggests that eating fruit at the end of a meal is a healthy habit since fruits are rich in polyphenols. Full story.
