Oxidative stress occurs when compounds that are not useful for life are produced in our bodies.

When Rafael decided to order a plate of beans during dinner at a work conference, a colleague told him: Today you are going to make your erythrocytes (also called red blood cells) work!

The comment surprised him, since he had always understood that beans had an antioxidant character that helped improve oxidative stress procedures.

This develops in the body over the years. But reality shows that beans also contain oxidants or pro-oxidants such as vicin or convicin, so their consumption produces an increase in oxidative stress.

What is oxidative stress?

Oxidative stress is inherent to life on planet Earth.
