Independent studies confirm blueberries as the world's healthiest food
Blueberries just might be the world's healthiest food. Scientists at the U.S.
Department of Agriculture Human Nutrition Research Center on Aging stated
that blueberries were one of the healthiest foods one could eat. They studied
over 100 different kinds of food which included fruits, nuts, vegetables, dried
fruits as well as herbs and spices. Specifically, they measured total
antioxidant capacity of each food and blueberry was found to have the
greatest amount of
antioxidants of any fruit or vegetable.
Research indicates that blueberries are packed with unique antioxidants that
help prevent radical damage. They contain pigments that enhance the effects of
vitamin C, support capillary integrity and stabilize the collagen matrix which
is the structural substance of all body tissues. Blueberry extracts also seem to
inhibit LDL oxidation and reduce inflammation.
A study in the August 2005 issue of the Journal of Medicinal Food concluded that:
"Whole wild blueberries may have implications in blood pressure regulation and could prove to have a therapeutic role in improving cardiovascular health."
A study reported in the April 2005 issue of Nutritional Neuroscience
indicated that improvements in memory and learning may be enhanced. An analysis of the brains of rats fed blueberry for 8 to 10 weeks
found that blueberry phytochemicals had crossed the blood-brain barrier and were
found in regions of the brain related to memory and learning. Another study to
substantiate that finding is found in the September 1999 issue of the Journal
of Neuroscience. That particular study found that rats supplemented with
blueberry showed reduced age-related declines in cognitive and brain function.
Additional evidence also comes from scientists at Tufts University when in 2005
they found a mechanism whereby a diet supplemented with blueberries was able to
reverse signs of neurological aging.
There are two main components that give blueberry it's potent antioxidant
effects. Anthocyanins and pterostilbene have properties that go well beyond
neutralizing free radicals such as maintaining DNA structure within cells. It
has been found in studies with rats that brain damage related to aging can be
minimized and in some cases even stopped. In fact the effects seen in these
studies are closely related to the same positive effects seen in studies with
calorie restriction which is also closely related to delaying the effects of
aging.
It is important to note that wild blueberries show greater antioxidant
potency that cultivated blueberries.
