Here is good news for people who like to scoff down piles of grapes and blueberries; you could be doing your brain a favour, and whose brain, today, does not need a favour?

“Polyphenol extracts from grapes and blueberry help reduce cognitive decline, according to a study published in The Journals of Gerontology; Biological and Medical Sciences. In the study, French and Canadian researchers examined the effects of the consumption of polyphenol grape and blueberry extract on memory. The researchers conducted an earlier study in a mouse model in which they found that berries, berry extracts, or isolated flavonoids could hamper age-related cognitive decline. For the current study, the researchers recruited 215 healthy people aged between 60 and 70 years old and whose body mass index (BMI) ranges from 20 to 30. The participants either consumed 300 milligrams (mg) of the grape and blueberry extract or a placebo in two capsules every day for six months. They also had three visits with the researchers: a screening visit, a baseline measurement session, and a final visit. Moreover, they performed memory function tests. Results revealed that the supplementation with the grape and blueberry extract enhanced the memory of participants with a lower level of memory performance. The researchers emphasized that the poorer performing participants exhibited the most improvements. “Subjects who were performing like 83-year-olds at the beginning, they were performing like 69-year-olds at the end,” said Barry Ritz, one of the researchers.
I suppose it could be possible to put together the ultimate brain health sweet, consisting of grapes, blueberries, topped with brain-saving turmeric and cinnamon, to keep our ageing brain cells running like a two bob watch, instead of a shilling watch.
