Oxidative damage is believed to be one of the mechanisms behind aging and many diseases. It involves free radicals, highly reactive molecules with unpaired electrons. Free radicals tend to react with important organic substances, such as fatty acids, proteins or DNA.
The main reason antioxidants are so beneficial, is that they protect our bodies from free radicals. Curcumin happens to be a potent antioxidant that can neutralize free radicals due to its chemical structure (15, 16).
In that way, curcumin delivers a one-two punch against free radicals. It blocks them directly, then stimulates the body’s own antioxidant mechanisms.
