What exactly are these free radicals? 

Well, we call so free, unpaired oxygen electrons that arise in the body as a result of metabolic changes. Their presence is related to defense mechanisms, but the excess is definitely harmful. Free radicals are endowed with a negative charge and strive to connect with a positive molecule, and the course of this molecular linking reaction is called oxidation. This causes damage to proteins, fats and nucleic acids of healthy cells, as well as havoc in our oxygen resources. The effect of this action may also be damage to DNA and cell membranes. Currently, it is believed that this may be the beginning of various diseases and also affect the aging process of the body.

I know what these antioxidants are, but now how do I give them in the diet? 

The answer is very simple by increasing the consumption of fruit. 

They contain the highest antioxidant properties to the ability to absorb oxygen radicals (ORAC). The daily recommended dose of ORAC values ​​is from 3 to 5,000 units. 


Sample fruit values ​​in ORAC units per 100 grams of product 

dried plums 5770 

raisins 2830 

blueberries 2400 

blackberries 2036
