Mechanisms Of Blueberries’ Life-Extending Properties
How do blueberries manage to prolong life and improve function so dramatically? We’re nowhere near a definitive answer, given the complexity of the berries’ biochemistry, but some key points are beginning to emerge, centered on the body’s own ability to repair itself.
Blueberries and their polyphenol components appear to be exceptionally good at promoting repair of DNA strands and at optimizing immunity at the cellular level.7,21,22 Both of these functions are essential for preventing senescent and environmental impacts that lead to cancer,23,24 cardiovascular disease,25,26 and loss of metabolic control,27,28 that underlies obesity and diabetes.
DNA, the molecular blueprint that contains instructions for all life functions, is a delicate molecule that, despite many protective mechanisms, readily suffers damage from oxidation, radiation, toxic chemicals,29,30 and other sources of stress. All living cells have evolved mechanisms to identify and repair broken DNA strands, which if left unrepaired, promote cancer and early cell death.31 Numerous studies now reveal that blueberry extracts both prevent DNA damage and promote its rapid and accurate repair.7,32-40
Human Study Corroborates DNA Protection
In an impressive human study, healthy volunteers ingested either 300 grams of ground blueberries or a control jelly with no blueberry components.41 Blood samples were taken before, and one, two, and 24 hours after the subjects took the study supplement. At the end of one hour, the amount of oxidation-induced DNA damage in blueberry-supplemented volunteers fell by 18% compared with control subjects. What makes this study particularly impressive is that this single, albeit large, serving of blueberries was able to suppress this amount of DNA damage so quickly.
