Polyphenols are a type of antioxidants present in plant-based foods such as cranberries, grapes, olives, walnuts, and other healthy foods, confer significant health benefits. These benefits include protection against Alzheimer’s disease and other memory problems and protection against cancer via DNA protection. Other benefits include shortened recovery time for colds, flu and other viral infections, and better physical appearance via better skin appearance.
One benefit of polyphenols is protection against Alzheimer’s disease and other memory problems. Though susceptibility to memory degradation has many contributing factors, including family history, presence or absence of mental stimulation, and general lifestyle, free radicals also play a role. Free radicals are harmful oxygen molecules that form as a result of exposure to environmental toxins and as a result of the normal human aging process. These particles damage the brain. Polyphenols deactivate free radicals before they can erode memory.
Polyphenols may also be able to help with cancer protection. The afore-mentioned free radicals, in addition to damaging the brain, can also cause harm to the DNA contained within all body cells. Sometimes, this causes damage to the DNA codes that control cell replication and cellular lifespan. When this happens, cells can start multiplying out of control, forming masses that eventually form cancerous tumors. Polyphenols can help lower cancer risk by deactivating free radicals, thus preventing DNA damage.
A third benefit of polyphenols is quicker recovery from colds, flu, and other minor viral infections. Apple skins, as well as other bright red or purple-colored fruits such as cranberries, dark grapes and raspberries, contain specific polyphenols that are antagonistic to viruses. Specifically, these compounds interfere with virus’ ability to attach to cells; a key part of the virus life-cycle. When viruses can’t reproduce, the body has an easier time eliminating them, shortening recovery time.
Finally, these antioxidants can help create a better physical appearance through improved appearance of the skin. Walnuts, olives and other foods rich in healthy vegetable-based polyunsaturated fat contain polyphenols that protect the skin from environmental damage, such as solar radiation. These compounds also help skin maintain its elasticity and natural vibrancy. That reduces the appearance of wrinkles and improves overall skin tone, though it remains a good idea to wear sunscreen.
