More Antioxidants in Loose Tea or Tea Bags?

Tea (from the Camellia sinensis plant) is a rich source of flavonoid phytonutrients, which function as antioxidants. The amount and relative proportion of these compounds in tea leaves depends on a variety of factors, including growing conditions, post-harvest processing (including the fermentation that converts green tea to oolong and black teas) and storage time before brewing. The form of tea, whether as loose leaf or the broken leaf (pekoe) and even smaller particles (fannings or dust) in bags, is not a clear determinant of its antioxidant capacity.

New Dietary Approach Against Alzheimers

While both a Mediterranean-style diet and the DASH eating plan are associated with brain benefits, a hybrid dietary pattern that combines the best of both with the latest cognitive research may protect memory and thinking even better. A new study reports that the MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) diet was associated with a slower rate of cognitive decline-equivalent to 7.5 years of younger age. Those with the highest MIND diet scores were 53% less likely to develop Alzheimers disease than those with the lowest scores.

Is Chocolate Actually Good for Your Heart?

Chocolate lovers are turning their candy wrappers into celebratory confetti over recent headlines (The More Chocolate, the Better) linking chocolate consumption to lower risk of cardiovascular disease and stroke. While previous studies have suggested the flavonoid compounds in dark chocolate might have heart benefits, the findings also associated milk-chocolate consumption with reduced risk.However, this result is not unexpected, says Jeffrey Blumberg, PhD, director of Tufts HNRCA Antioxidants Research Laboratory, because milk chocolate does contain flavonoids (about 75 milligrams per 100 grams)-more than found in a comparable amount of red wine or tea, though less than dark chocolate (170 milligrams per 100 grams). Flavonoids in milk versus dark chocolate vary markedly by brand, however; these values are averages.

New Evidence of Brain Benefits from Following a Mediterranean-Style Diet

A newly published followup to findings from a study of the so-called Mediterranean diet adds to the evidence that such an eating pattern, especially when it includes nuts and olive oil, may help protect the aging brain. Results from a subgroup of the Spanish PREDIMED study showed that those assigned to a Mediterranean diet held steady in cognition while a control group declined. While previous observational studies have linked a traditional Mediterranean-style dietary pattern to cognitive protection, this is the first such evidence from a large randomized clinical trial.
