Anti-oxidants

 

Hello everyone!  This month we shall talk about some things call anti-oxidants. Oxidation is a process that adds oxygen to something else. So, when oxygen is added to hydrogen it produces something very common that is water or H2O. Similarly, when wood is burnt it is oxidized it is called burning. Our bodies are good at burning foods to produce energy. The food we eat is ‘burnt’ slowly in a controlled manner to produce energy the body needs. During this ‘burning’ process things called ‘free radicles’ are produced, these ‘free radicles’ like the term implies are very reactive and interfere with normal metabolic processes. Normally these ‘free radicles’ are cleared and neutralized by the body using things called free radicle scavengers, and under normal circumstances there is a balance between these free radicles and free radicle scavengers. However, this balance is not always stable and the amount of free radicles exceed the amount of scavengers required for clearing. This imbalance is what creates problems.

Unfortunately, ‘free radicles’ are also formed from external sources such as exposure to X-rays, ozone, cigarette smoking, air pollutants, industrial chemicals and so on including certain diets. So increasing the amount of antioxidants in one’s diet can help regain this balance.

Now what are these anti-oxidants? By definition antioxidants are molecules that inhibit the oxidation of other molecules. One of the most common antioxidant is vitamin C also called ascorbic acid. Vitamin C is an essential nutrient and is shown to be involved in tissue repair. Some of the common foods that are rich in vitamin C are citrus fruits, tomatoes, red peppers and so on. Sometimes vitamin C is added to common foods such as chips to prevent rancidity and preserve flavor. Oils turn rancid due to oxidation and vitamin C prevents this oxidation.

Numerous studies have shown that vitamin C can deeply inhibit the growth of several cancer cell lines making it an important vitamin that the body needs. The best way to take this supplement is through vitamin C rich foods such as fresh fruits and vegetables. So like I always say, “Eat healthy, eat wise, exercise daily and lead a happy life”.
