Antioxidants that are reducing agents can also act as pro-oxidants. For example, vitamin C has antioxidant activity when it reduces oxidizing substances such as hydrogen peroxide; [93] however, it will also reduce metal ions such as iron and copper [94] that generate free radicals through the Fenton reaction.
Antioxidants are important because they fight free radicals (i.e., harmful molecules) that would otherwise damage healthy cells. Antioxidants also reduce inflammation and the risk of chronic ...
Pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate): A primary antioxidant consisting of sterically hindered phenols with para-propionate groups. Primary antioxidants (also known as chain-breaking antioxidants) act as radical scavengers and remove peroxy radicals (ROO•), as well as to a lesser extent alkoxy radicals (RO•), hydroxyl radicals (HO•) and alkyl radicals (R•).
Antioxidant compounds reduce reactive oxygen species (ROS), which reduces emitted free-radicals. When ROS function is impaired, there is more susceptibility to atopic disorders or diseases due to impairment of the attack-kill-present-respond behavior of the Th-1 immune response chain. Over-consumption of antioxidants could thus lead to ...
“The Mediterranean diet supports brain health by reducing inflammation and oxidative stress through its rich antioxidants, healthy fats like omega-3s from fish and olive oil, and high polyphenol ...
For example, if you want to up the fiber ante even further and bring in some antioxidants — which help protect cells from damage caused by free radicals — add strawberries, blueberries ...
Vitamins that are reducing agents can be pro-oxidants. Vitamin C has antioxidant activity when it reduces oxidizing substances such as hydrogen peroxide, [6] however, it can also reduce metal ions which leads to the generation of free radicals through the Fenton reaction.

Beets are one of the most antioxidant-rich foods available, meaning they help fight free radicals that could damage our healthy cells and lead to chronic disease.
