Oxidative damage is not limited to your cells and DNA.

It is also problematic when your “bad” LDL cholesterol is oxidized.

The antioxidants in blueberries are strongly linked to reduced levels of oxidized LDL. This makes blueberries very good for your heart (15).

A daily 2-ounce (50-gram) serving of blueberries lowered LDL oxidation by 27% over eight weeks in obese people who were obese (16).

Another study determined that eating 2.5 ounces (75 grams) of blueberries with a main meal significantly reduced the oxidation of “bad” LDL cholesterol (17).
