Antioxidants, Why do you need antioxidants, sourcing antioxidants, how to source antioxidants

Free radicals are naturally formed molecules in your body that can cause heart disease, cancer and other diseases. Antioxidants work to defend your body against free radical accumulation. Free radical accumulation can cause oxidative stress, which can damage your DNA and cell structure, causing diseases. Antioxidants help your body fight off oxidative stress caused by free radicals, thereby reducing the risk of disease. 

Antioxidants are integral components in fighting the damage caused by free radicals. Free radical build-up in your body could cause premature ageing further to other diseases as mentioned; heart disease and cancer. 

With all the benefits of antioxidants, you may be wondering where to source them. Antioxidants such as vitamin C and E and carotenoids are found in fruits, vegetables, grains and nuts. A diet rich in antioxidants should contain all four components including, seeds, herbs and spices. A plant-based diet is most effective when sourcing antioxidants. We will look at the specific sources of antioxidants as we list out 14 high antioxidant sources, which you can acquire through your diet.

Considered essential for survival, it is integral to your health that you understand the importance of antioxidants and find comfortable sources in order to get a wholesome amount of antioxidants from your diet.

What Are Antioxidants

Antioxidants refer to molecules that are found in food, that protect your cells from oxidation. Oxidation, the more serious phenomenon of oxidative stress can have a damaging effect on your cells including your DNA and various proteins in your body,

Damaged DNA can lead to various concerns for they prevent your cells from functioning normally, thereby causing your cells to malfunction or even die. As mentioned prior, oxidative stress is caused by the build-up of free radicals in your body. 

Antioxidants work to neutralise the effects of free radicals, thereby ensuring that your health is preserved. Though there are antioxidant supplements in the market, it is not always easy to find a reliable source of supplements, hence a diet rich in antioxidants is recommended to maintaining optimum health. 

High doses of antioxidants as found in supplementation can have a damaging effect on your body. A study conducted on 100,000 people using antioxidant supplements found no reduced risk of developing diseases such as cancer and heart disease. Further to this, supplementing high doses of antioxidants such as beta-carotene may actually increase the chances of developing lung cancer in smokers. Hence we do not recommend that you supplement your diet in search of a miracle cure through antioxidants. Instead opt for a natural diet, which is high in antioxidants, to reap all the benefits of low concentrations of the various types of antioxidants. 

There are various types of antioxidants that you find in varying concentrations in your food. Here are a few types of antioxidants to get a better idea of the variety involved. Vitamin C and E are antioxidants that are considered great for your hair and skin. Selenium, another antioxidant helps fight cancer and boosts your immune system. Carotenoids are an integral component in maintaining optimum eye health. Carotenoids come in various forms, such as beta-carotene, lycopene, lutein and zeaxanthin. 

Antioxidants can be subdivided into three categories based on the functions they perform. Primary antioxidants help eliminate free radicals in your body as mentioned above. Secondary antioxidants are known as preventive antioxidants, which stunts chain initiation, the first step in the free radical reaction mechanism. Secondary antioxidants thus work to prevent the formation of free radicals in your body. Tertiary antioxidants work to repair the damage caused, by restoring the health of biomolecules and cells in your body. 

Antioxidant deficiency is also known as increased oxygen species (ROS). Antioxidants can further be categorised into two main types, small molecule antioxidants and large molecule antioxidants. Small molecule antioxidants work to neutralise antioxidant deficiency or ROS, enabling the proper expelling of free radicals from your body. Small molecule antioxidants include vitamin C, vitamin E, carotenoids and glutathione.

Large molecule antioxidants help absorb free radicals, thereby preventing them from attacking other essential cells and proteins in your body. These include enzymes such as superoxide dismutase, catalase and glutathione perioxidases. 

Ferric reducing ability of plasma, also known as FRAP is a great test in understanding the content value of antioxidants in food. The higher the FRAP value, the more antioxidants a food contains. We will look at the various sources of antioxidants further down this article.

How do Antioxidants Work

The science behind how antioxidants work is rather simple. Antioxidants work to generously give up electrons to free radicals, without turning into electron-scavenging substances themselves. 
 
 
Thus, antioxidants work to repair the damage caused at the cell level by the works of free radicals. They also work to completely break down free radical molecules in your body thus rendering them harmless. Further to this, antioxidants work to stop the chain reaction which leads to the formation of free radicals, which works to help boost your immune system. 
 
 
They also work in restoring the cell damage caused by free radicals.
