Why Blueberries are Irritatingly Good for You

Blueberries - we’ve all heard about how they’re a wonderful superfood, that they are a good source of antioxidants, and that they are delicious. They can be helpful for blood sugar regulation, help to prevent oxidative damage in different parts of the body, and have been touted as a healthful food for many years.

But why are they so great? Once digested do blueberry constituents turn into little molecules of unicorn dust that help magic away all of our ails? Almost, but not quite. 😉

The main active constituent in blueberries is a group of molecules called proanthocyanidins - these are the ones that get all the credit for this antioxidant and anti-inflammatory activity. These molecules are actually slightly toxic to humans! It’s a little weird that something slightly toxic would be considered a superfood, right?

Here is what happens: we eat the blueberries, and we digestively absorb the active constituents into our bloodstream for a period of 15-20 minutes. This short time period is enough for our bodies to up-regulate its own anti-inflammatory and antioxidant pathways to counteract the slight toxicity of the blueberries. So, it may seem that the blueberries themselves are helping you be a little healthier every time you eat them, but it’s your own body doing the important work!
