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.
