Nov. 24, 2017; by Briana McDonald- Staff Writer, Silver Bulletin e-News Magazine (UtopiaSilver.com) Did you know blueberry extracts have demonstrated robust DNA repair properties?? That’s right, blueberries! Cellular DNA endures relentless injury through internal and external factors. The fundamental problem with aging is faulty DNA repair, so by incorporating healing foods like blueberries into our diet that help perfect internal DNA repair process we can help ourselves become more resistant to degenerative diseases. You can assist DNA repair process with blueberries and blueberry extracts which have been proven to augment memory and cognitive abilities and decelerate the aging process in many organs.
Life Extending Properties of Blueberries
How do blueberries prolong life and assist DNA repair process? Although there is not a definitive answer given the complexity of the blueberries biochemistry their polyphenol components appear to be exceptionally good at promoting repair of DNA strands and optimizing immunity at the cellular level. Both of these functions are important in preventing cancer, cardiovascular disease, obesity, and diabetes.
DNA is the molecular blueprint that contains instructions for all life functions and is a delicate molecule that readily suffers damage from oxidation, radiation, toxic chemicals and even from everyday stress. All living organisms have evolved mechanisms to identify and repair broken DNA strands, which left un-repaired promote the onset of cancer and early cell death.
In an impressive human study, healthy volunteers ingested either 300 grams of ground blueberries or a control jelly with no blueberry components. Blood samples were taken before, and one, two, and 24 hours after the subjects took the study supplement. At the end of the hour the amount of oxidation induced DNA damage in blueberry supplemented volunteers fell by 18% compared with control subjects. This is particularly impressive in that this one large dose of blueberries was able to suppress the amount of DNA damage so quickly. (1)
Blueberries Boost Natural Killer Immune Cells
As we age, the actions of many immune system components can decline in a degenerative process called immunosenescence. Controlling and slowing this process is a means of prolonging life and health. Blueberry extracts have been shown to have powerful anti-aging benefits on both cellular and molecular components of the immune system. At the cellular level, blueberries boost the actions of natural killer cells charged with identifying and destroying abnormal cells such as those infected with viruses or those showing malignant shifts. Blueberry anthocyanins decreased activation of nuclear factor kappa-beta, which is an inflammation-generating molecule associated with cancer, heart disease, and other manifestations of chronic inflammation.
Blueberries and Cardiovascular Health
Oxidative damage is not limited to our cells and DNA, it is also problematic when our circulating lipoproteins, the “bad” cholesterol are oxidized. The oxidation of LDL is a crucial step in the heart disease process but fortunately for us, the antioxidants in blueberries are strongly linked to reduced levels of oxidized LDL. A daily 50 gram serving of blueberries lowered LDL oxidation by 27% in obese participants after a period of 8 weeks and another study showed that 75 grams of blueberries with a main meal significantly reduced the oxidation of LDL.

Blueberries and Brain Health
Oxidative stress will also affect the health of our brains, but have no fear blueberries can help in that department as well. According to animal studies, the antioxidants in blueberries accumulate in the areas of the brain that are essential for intelligence and they appear to directly interact with aging neurons which lead to improvements in cell signaling. In human studies with mild cognitive impairment, those that consumed blueberry juice every day for 12 weeks saw improvements in several markers of brain function. And a 6 year study of over 16,000 elderly patients found that blueberries and strawberries were linked to delays in cognitive aging by up to 2.5 years! (3)
