Studies find blueberries help with healthy aging
Scientists have found yet another health benefit of eating blueberries.
The Gerontological Society reports that a number of recent studies indicate they aid healthy aging.
One study suggests that consuming about one cup of blueberries daily can improve blood vessel function and decrease systolic blood pressure. That ability is said be associated with the phytochemicals that give blueberries their dark colour.
According to the society other studies documented the cognitive benefits of eating blueberries.
One linked the fruits' high polyphenol count to improve performance on memory tests by a group of older adults, while another provides a review of several clinical studies focusing on benefits of blueberry supplementation with a focus on specific memory effects in children, as well as older adults with mild cognitive impairment.
"Since the 1990s, research on the health benefits of blueberries has grown exponentially," wrote guest editor Donald K. Ingram, PhD, FGSA, in an opening editorial.
"Studies have documented that this fruit ranks highest in antioxidant activity compared to many other popular fruits. Moreover, other mechanisms for the health benefits of blueberries, such as their anti-inflammatory properties, have been identified."
The group of articles also featured a rodent study, which presents data on the improved memory performance of blueberry-supplemented aged rats compared to rats on a control diet.
