The evidence keeps piling up that certain foods are associated with health, while other foods (e.g., soda, ultra processed foods) are associated with chronic diseases. A recent article reported the results of several studies finding certain foods linked to cardiovascular health, including lowering blood pressure.

But guess what? They are popular foods available to everyone - cocoa, green tea, black tea, apples, grapes, and berries.

There is strong evidence certain plant compounds (flavan-3-ols, also known as flavanols or catechins) in these foods have beneficial effects on cardiovascular health. These compounds can lower blood pressure and improve endothelial function (functioning of the blood vessels). Two to three cups of tea daily! One to two servings of dark chocolate daily! Instead of chips for a snack, have an apple.

By the way, rather than focusing on eating just certain foods, it's better to improve your entire diet by eating more fruits, vegetables, whole grains, legumes, seeds, and nuts. All these foods are linked to good health and are considered part of a heart-healthy diet.

From Medscape: From Apples to Cocoa: Everyday Foods Linked to CV Benefits

The term “healthy diet” is often used but frequently remains vague. This is why scientific research into specific food components with preventive potential is gaining importance. Current studies suggest that certain plant compounds found in everyday foods such as apples, cocoa, and tea may have beneficial effects on cardiovascular (CV) health. ...continue reading "Common Foods Linked to Improved Heart Function"

 Well, it looks like the researchers devised a nutritional supplement, which they then tested and found beneficial effects on the thinking processes of older adults - so some bias there, but still interesting. What was in the supplement they called NT-020? Extracts of blueberries, green tea, vitamin D3, and amino acids such as carnosine. Science Daily:

Nutritional supplement improves cognitive performance in older adults, study finds

Now a University of South Florida (USF) study reports that a formula of nutrients high in antioxidants and other natural components helped boost the speed at which the brains of older adults processed information.

The USF-developed nutritional supplement, containing extracts from blueberries and green tea combined with vitamin D3 and amino acids, including carnosine, was tested by the USF researchers in a clinical trial enrolling 105 healthy adults, ages 65 to 85. The two-month study evaluated the effects of the formula, called NT-020, on the cognitive performance of these older adults, who had no diagnosed memory disorders.

Those randomized to the group of 52 volunteers receiving NT-020 demonstrated improvements in cognitive processing speed, while the 53 volunteers randomized to receive a placebo did not. Reduced cognitive processing speed, which can slow thinking and learning, has been associated with advancing age, the researchers said. Blueberries, a major ingredient in the NT-020 formula, are rich in polyphenols, a type of antioxidant containing a polyphenolic, or natural phenol substructure.

In several preclinical trials, researchers gave aging laboratory rats NT-020 to see if it boosted memory and other cognitive performance by promoting the health of neurons in the aging brain. Those studies demonstrated that NT-020 promoted the growth of stem cells in the brain, produced an overall rejuvenating effect, benefited animals with simulated stroke, and led to better cognitive performance.
