Why Blueberries Are Good For Your Brain
Blueberries are nothing short of magic for your body. Blueberries have the highest antioxidant capacity of any food tested so far1. This means that the chemicals in blueberries help prevent your body AND brain from deteriorating better than any other food on the planet. Every day your body takes a serious beating from the foods you eat, the air you breathe, chemicals you encounter, sunlight, and even cosmic radiation flying at you from outerspace (it's true!). All of these things produce "free radicals", molecules that are just plain mean and go around destroying important things inside your cells like DNA and proteins, ultimately damaging and killing your cells. This means not only cells in your skin, but also in your muscles, bones, organs, and BRAIN! But blueberries, with their incredible antioxidant capacity, fight and destroy these "free radicals" to keep your cells healthy and happy. They are the ultimate soldiers.
When rats were fed blueberries some amazing things happened. The blueberries PREVENTED age-related declines in movement and brain function! The rats' cells were more responsive and healthier, and THE RATS COULD LEARN FASTER and had BETTER MEMORIES2,3,4. Not even rats that were fed Vitamin E did better. This is because blueberries contain OTHER molecules besides vitamins that fight to keep your body's and brain's cells healthy.
A few other amazing things about blueberries have been found as well: some results show that blueberries INCREASE THE NUMBER OF NEW NEURONS YOUR BRAIN MAKES EVERY DAY5, increase the ability of your neurons to talk to each other6, and even improve the survival and function of grafted neurons in rats with Parkinson's Disease7. How incredible is that? Can you imagine how much we DON'T KNOW about blueberries yet?
This is why blueberries are nothing short of magic for your body.
