Everybody is talking about antioxidants these days. The miracle nutrient which is responsible for helping us stay young, warding off chronic disorders to fighting toxic elements in our system. What exactly are these and where are they available?? I have tried explaining antioxidants in a simple manner which I hope will help you understand it a little better.
Understanding Antioxidants
Nutritionists and Medical Professionals are excited about “Antioxidants” since more and more research tells us that these nutrients provide more than the “classical help” needed for the “Young to grow” and “Old to maintain”. You may have heard about the health benefits of antioxidants too, but what is an antioxidant and how do they actually work?
What do they do?
“Antioxidants” are dietary substances, including nutrients which prevent the damage to your body cells or repair the damage that has been done. They are called so indicating the mechanism by which they prevent disease. In humans, a small but significant percentage of oxygen molecules in the body become electrically charged due to natural cellular activity and/or exposure to environmental factors such as smoking, radiation etc. This oxygen molecule becomes a free radical as it undergoes a process of oxidation. When an oxygen molecule becomes electrically charged or "radicalized" it tries to steal electrons from other molecules, causing damage to the DNA and other molecules. These free radicals continue to damage cells which may play a role in the development of certain conditions like cancer, CVD, Cognitive impairment, Alzeimers disease, Immune dysfunction, cataracts and ageing. Antioxidants, by their very nature, are capable of stabilizing free radicals before they can react and cause harm, in much the same way that a buffer stabilizes an acid to maintain a normal pH. They neutralize the free radical and prevent them from taking electrons from other molecules.
Where are they available?
Antioxidants are present in foods as vitamins, minerals and in distinctive colours of fruits and vegetables called “Phytochemicals”. They are abundant in fresh fruits and vegetables, as well as in other foods including nuts, whole grains, fish and some Indian spices. Given below is a list of antioxidants found in various foods
Vit A ---------- Fish, Liver and dairy products
Vit C-----------Citrus fruits like oranges and sweet lime
Vit E-----------Found in oils, fortified cereals, legumes and nuts
Selenium-----Mineral found in nuts, meat and plant food
Omega 3 Fatty Acids ------- Fatty fish, nuts, soya bean and Flax seeds
Phytochemicals-----The rich colour found in various fruits and vegetables are due to pigments which act as antioxidants. Not only do they look and taste good, they also help us to be healthy. Given below is a list of colours found in foods which act as antioxidants.
Carotenoids ------Carotene, Lutein, Zeaxanthin ----------Carrots,spinach
Lycopene -------------Tomato
Flavanoids --------- Anthocyanidines ----------- Berries, Cherries and Red grapes
Flavanols --------Catechins, Epicatechins --------- Apples, Grapes, Cocoa, Onions, Broccoli
Sulphides -------- Diallyl Sulphide ------- Garlic, Onions, Leeks
Thioles ---------- Cruciferous Vegetables ------ Cabbage, Broccoli, Collards
How to increase the intake of Antioxidants in the diet?
- Eat a variety of foods as Antioxidants are widely distributed in nature
- Add colour to your plate. Dark coloured fruits and vegetables are good sources of Antioxidants. Increase the consumption of fruits and vegetables. Your plate should look like a box of crayons!!
- For optimal health, eat them regularly
Supplement or not to supplement?
Read any fitness/health magazine, watch a few TV ads or simply pass by your local health food store, and notice the benefits of the latest supplements touted. While new products emerge frequently, it is best to remember that supplements are not to be used as substitutes for a healthy diet. In fact, due to many conflicting studies on the effects of antioxidant supplementation, the American Heart Association currently does not recommend using antioxidant supplements unless absolutely necessary. It is also important to note that we can “Over supplement” taking more than what is recommended, creating a risk of toxicity. Besides a good diet offer multiple benefits.
Bottom line
Remember! In your body, the antioxidant process is similar to stopping an apple from browning. Once you cut an apple, it begins to brown. But if you dip it in orange juice which contains vit C, it stays white. Your eating plan should contain plenty of fruits, veg, whole grains and nuts which can supply all the anti oxidants that your body needs!!!
