Antioxidants: Mechanism

Let us rewind to the basic lesson from the science class, where you were introduced to atoms’ main components, protons, electrons, and neutrons. Now, molecules are made up of two or more atoms and require electrons to remain stable. Failing to do that, molecules might turn into free radicals which can disrupt the balance of good molecules.

Health Benefits Of Antioxidants

Antioxidants work in the same mechanism, they fight off the free radicals in your body and promote harmony in bodily functions. Exposure to air pollution, heavy metals, chemicals, and harmful smoke, can give rise to free radicals in your body. With the right amount of antioxidants present in your body, your body’s natural response to fight off infections and diseases is increased.

The imbalance of the antioxidants in your body can lead to oxidative stress which is the root cause of many chronic diseases. Like autoimmune disorders, Parkinson’s disease, diabetes, Cancer, and Alzheimer’s disease. Our body’s natural response to any danger is what helps us overcome it.

Health Benefits Of Antioxidants

Now that we understand the mechanism of antioxidants in our body, let us understand its role in keeping our body healthy.

1. Protects Cell From Free Radical

The primary instinct of antioxidants is to neutralize the free radicals in your body to maintain optimal function. When the free radicals increase it has the potential to damage the cells and their structure. To avoid this, antioxidants help to counteract the attacks from the free radicals. In some cases, the free radicals are not fought off completely, but their ability to destroy the cells is executed.

2. Decreases Inflammation From Our Body

 When you get hurt or have had recent surgery, your wound is open and starts to heal on its own. Yes, there is an added effect of medicine, but the purpose of that medicine is to ensure faster recovery, your cells are already at work to heal the wound. Antioxidants play a major role in reducing inflammation of any kind in our body. 

3. Good For Heart Health

Individuals suffering from heart conditions are often patients with high cholesterol. Antioxidants help to prevent the oxidation process of the bad cholesterol. When LDL or low-density lipoprotein is oxidized it can lead to blockage of an artery, blood clots in the blood vessels, or worse a stroke. These conditions can be avoided if the antioxidant levels are ideal in the body.
