ORAC (oxygen radical absorbance capacity) indicates the antioxidant capacity of different foods. ORAC values can be measured in a laboratory. The highest ORAC values can be found in cocoa beans, followed by aronia berries.
Oxidative stress is understood to mean constant attacks to the body by free radicals that cause minimal yet permanent destruction. Degenerative diseases like type 2 diabetes, Alzheimer’s, rheumatism, arthrosis and arteriosclerosis are often triggered by oxidative stress. Oxidative stress can also cause mutations (and therefore cancer) in the body.
