WHAT ARE THE HEALTH BENEFITS OF ANTIOXIDANTS?
All cells need oxygen to live and work but is the same oxygen that can be responsible for the damage of cells through a process known as oxidation. When oxidation takes form "free radicals" that have the ability to damage cells. Free radicals are substances that contain unpaired electrons as they have lost or gained an electron. Free radicals are formed as a result of infection or inflammation determined by certain environmental conditions such as smoking or air pollution due to exposure to pesticides and insecticides. When free radicals are able to do damage for prolonged periods of time, this can lead to diseases such as cancer. Antioxidants are vitamins, minerals and enzymes that are sometimes used to reverse to some extent the effects of oxidation. In this article we will explore what are antioxidants, they work for our health and what are some of the best sources of antioxidants.
HOW DOES AN ANTIOXIDANT?
Our bodies need a constant supply of antioxidants due to the fact that antioxidants are oxidized by the body naturally during the day. We have often seen use lemon juice to prevent oxidation of sliced \u200b\u200bfruit and avoid dark. The color change from white to brown due to oxidation. With the lemon juice antioxidant that contains the fruit does not turn brown, but retains its original color. It 'so important to take antioxidants with food so that this supplement may protect the cells in our body. An antioxidant works in practice by neutralizing free radicals that are generated during oxidation.
HOW DOES AN ANTIOXIDANT?
When a free radical is formed during the oxidation it is in an unstable state. He, therefore, the tendency to absorb or release electrons from other living cells. Each time an electron is released or absorbed, forming another free radical. 'S why we need a constant supply of antioxidants to our bodies. Free radicals are still doing the same thing, forming a chain. If you allow free radicals to reproduce for an extended period of time, this will damage living cells. When an antioxidant like vitamin C or vitamin E is introduced into the body, it will convert the free radical in its unstable form in a more stable molecule.
This process breaks the chain of free radicals and stop the oxidation process. In the case of some antioxidant enzymes, the process is a bit different. Enzymes such as catalase and glutathione slow down the speed with which they form the chain of free radicals. Once the already formed free radicals are stabilized, the process of oxidation can be stopped. The mechanism of each antioxidant only on some specific types of free radicals. On other types of free radicals the antioxidant may not have the same effect.
What are the sources of antioxidants?
The brightly colored fruits and vegetables are rich in antioxidants. There are literally thousands of different antioxidants in the food we eat and each has its own mechanism for neutralizing free radicals, while working as a team. Some of the most common and well-known antioxidants we consume in our diets are vitamin C, vitamin E, selenium and beta carotene. These are often referred to as anti-aging antioxidants that help keep young people through skin care. Nutritionists stress the importance of fruit and vegetables in our diet, because they are rich in antioxidant properties. The best sources of dietary antioxidants are the colorful fruit, vegetables such as broccoli, red grapes, beets, carrots and tomatoes to name a few.
In conclusion, it is very important that we continue to take anti-oxidants in our body through proper diet and with integration. We have mentioned the positive influence they may have with regard to aging, but also for protection against diseases such as cancer, heart disease, Alzheimer's disease and arthritis.
