What Are Antioxidants For?
Antioxidants play a crucial role in the processes within the human body. Without them, disease will flourish through inflammation and oxidation of our cells. Antioxidants remove metals from our body, detoxify our system, improve the immune system, and influence certain genes. Antioxidants are chemical substances found in nature and created synthetically that donates an electron to a free radical to make it harmless. The known functions are
1. They scavenge free radicals
2. They decrease markers of proinflammatory cytokines
3. They alter gene expression profiles
4. They alter protein kinase activity
5. They prevent release and toxicity of excessive amount of glutamate
6. They act as cofactors for several biological reactions
7. They induce cell differentiation and apoptosis in cancer cells
8. They induce cell differentiation in normal cells but not apoptosis
9. They increase immune functions
I believe if a person is unable to obtain all the necessary antioxidants through farm fresh food then yes supplementation is necessary to maintain homeostasis. Supplements are so readily available in every pharmacy and vitamin shop. Sometimes a person can be allergic or restricted from foods due to medication would supply the antioxidant but not the antioxidant itself so a supplement would be an excellent way to absorb this.
