11 Facts About Antioxidants You Need to Know!

What do sunburns, Alzheimer’s Disease, and wrinkled skin all have in common? The simple answer; free radicals.

Free radicals are a natural by-product of life. We create them when we’re stressed, when we eat foods fried at a high temperature, and when we breathe. They’re simply a part of life.

At a molecular level, they’re unstable molecules that are missing an electron, and steal one from an unsuspecting stable molecule making it unstable.

This microscopic game of finder’s keeper’s can damage cells and even our DNA, and can accelerate many disease processes including Alzheimer’s Disease and Diabetes.

But! Our body is full of antioxidant superheroes to the rescue!

We’ve all heard of antioxidants, but what are they really? In short, antioxidants have an extra electron, and can donate it to an unstable free radical without becoming unstable. They create a beautiful balance.

While free radicals are produced by many important bodily functions, like breathing (we need to breathe!), antioxidants come from the food we eat. Colourful fruits and veggies are the most potent source of antioxidants. Every colour contains a different antioxidant superhero. Vitamins A, C, & E, as well as selenium also contain potent antioxidant superpowers.

Superfoods get their “super” name mostly due to their huge amount of antioxidants.
