Have you ever heard of polyphenols? These powerful natural compounds are found in foods like blueberries, green tea, dark chocolate, olive oil, and red grapes — and science shows they play a vital role in protecting brain health as we age.
Recent studies confirm that polyphenols have strong antioxidant and anti-inflammatory effects. They help neutralize free radicals and reduce oxidative stress — one of the key drivers of cognitive decline and neurodegeneration.
According to research from the Harvard T.H. Chan School of Public Health, regular consumption of polyphenol-rich foods is associated with a lower risk of Alzheimer’s and other forms of dementia. They also support better blood flow to the brain and short-term memory.
The most researched types include:
Resveratrol (in red wine and grapes)
EGCG (in green tea)
Curcumin (from turmeric)
Quercetin (found in apples and onions)
💡 Adding these foods to your daily routine could be one of the easiest and most effective ways to keep your brain sharp and vibrant well into your golden years.
