The health industry is most certainly one of the biggest in the world. People will do just about anything to make sure that they are healthy and that they are at reduced risk for the contraction of disease. The problem is that most consumers do not really know the answer to questions such as what is an antioxidant. They simply rely on advertisements that tell them that they need it.
In order to survive every living entity needs oxygen. The oxygen plays an important role in providing the entity with energy. This is done by metabolizing the nutrients that the entity consumes. In the case of humans this may be carbohydrates, fats and a variety of proteins. Unfortunately, oxygen can become dangerous. This happens when it becomes part of potentially dangerous molecules called free radicals.
The human body has billions of cells. A molecular bond sees to it that the cells are held together, but if the bond becomes weak, the molecules can split apart. In the process, free radicals are created. Free radicals are unstable molecules that miss an electron. This happens during extreme exercise, during times of stress, and when the body is exposed to pollution and certain medicinal drugs.
Unfortunately, free radicals try to compensate for the missing electron by attacking healthy cells, and in this way a chain reaction is created when the cell that was attacked loses an electron. A new free radical is created and the process repeats itself over and over again. In this way millions of molecules can be destroyed. In humans, this can lead to a host of diseases such as cancer, arthritis and heart disease, to name just a few.
With free radicals raging through the body, causing damage and disease, only antioxidants can cause the process to cease. They are able to give an electron to free radicals without the danger of turning into a free radical themselves. This is because they will remain stable regardless of whether they possess the additional electron or not. In this way the chain reaction can be broken and the free radicals are absorbed into the antioxidants.
There are many foods that are rich in this miracle substance. Not all foods contain the same level, however. Tomatoes, all types of berries, green vegetables, beans, broccoli and prunes are just a few foods that contain high levels. The potency of the various foods to absorb free radicals is measured on the ORAC scale. Tomatoes, for example, enjoy a score of sixty while cherries score a hundred points, making the latter more powerful.
The pace of modern life, the excessive use of preservatives and the fact that so many types of food are processed makes it almost impossible for the human body to produce enough to deal with free radicals. The pace of modern life and the high stress levels that are becoming common also contribute in a negative way. That is why it is necessary to consume foods that are rich in this almost miraculous substance.
The most useful answer to the question on what is an antioxidant is perhaps that it is something everybody needs to consume every single day in order to stay healthy. Rampaging chains of free radicals can cause disease but small lifestyle changes can also go a long way in helping to prevent health problems. Food rich in this substance also hold many other positive advantages.
