Free Radicals and What Vitamin E Does to Combat Them
In today's health conscious society, you may have heard about free radicals and the possible effects that they can have on the body. But how much do you really know about them? Most likely you don't know as much information about free radicals as you need to. To ensure your health, you should know as much as possible about free radicals, their effects, and how you can combat them. It is important to have the most complete and accurate information so that you can take the steps necessary to remain healthy.
To fully understand free radicals, it is necessary to first understand how they are created. As you probably learned in high school, the body is made up of thousands and thousands of cells. These cells are made of molecules, which are made of up atoms bonded together. Inside each atom is a nucleus along with a certain number of neutrons, protons, and electrons. The numbers of protons, which are positively charged, present in the nucleus, also dictate the number of electrons that are also present. The electrons, negatively charged, are a part of the many chemical reactions that take place to bond the atoms together. This bond is necessary to form molecules.
Within the atom, the protons and neutrons are located in the nucleus. The electrons are located within several rings that surround the nucleus. Each ring contains a specific number of electrons. With the exception of the inner most ring, each ring holds up to eight electrons. The atom always seeks to have its outer most ring filled with electrons. To make sure this outer ring is filled, each atom gains or loses electrons to fill the outer ring or bonds with another atom so that the outer ring of each atom is filled. The most common way is for atoms to bond with other atoms and share electrons.
For now, be sure to read all the information available on Herb Alpert Fandango and Pediatric Nutrition so that you can make an informed decision. Don't just do the job half way.
A Snapshot On The History Of VitaminsSince the very beginning, man has known to eat. As knowledge evolved, he soon found that by eating different foods he could cure different ailments such as ... Once atoms have bonded together, it is highly unusual for them to split apart because this leaves the molecules with an odd number of electrons. In some instances, however, when there is a weak bond between the atoms, it is possible for them atoms to split apart. This is how free radicals form. Free radicals have an instability that leaves them vulnerable, seeking an extra electron so that it can once again become stable. Typically, free radicals steal an electron from a stable molecule that is closest to it. This, in turn, causes this new molecule to also become a free radical. There is a chain reaction of free radicals forming and taking electrons from other molecules. If the process continues, a living cell can be disrupted.
Sometimes free radicals are created normally during the metabolism process. They are also created by the immune system as a way to combat viruses and bacteria that are present in the body. Although these natural body processes create free radicals, there are some factors present in the environment that cause free radicals to form. These include cigarette smoke, herbicides, radiation, and pollution.
In most cases, the human body can naturally combat free radicals using antioxidants that are present in the body. When there are no antioxidants present, free radicals can begin to produce excessively and cause damage, especially with age.
Vitamin E is thought to be the most plentiful antioxidant present in the human body. The presence of Vitamin E helps to break the chain reaction that free radicals create. Antioxidants, Vitamin E included, have electrons of their own. They can help to neutralize the free radicals that are present in the body by giving up an electron. By doing this, Vitamin E ends the free radical process of stealing electrons from other molecules. After giving up an electron, the antioxidants do not become free radicals themselves. This is because they are stable even without a balance of electrons.
Getting Energy From VitaminsThe biggest complaint that doctors often hear from patients is a lack of energy, or the constant feeling of fatigue. Due to these types of complaints, it really isn't a surprise that ...
The best way to ensure that free radicals do not replicate excessively is to have a healthy amount of Vitamin E present in the body. A balanced diet consisting of at least five to eight servings of fruits and vegetables is ideal for fighting free radicals. Be careful not to overdo it though. Though the exact effect of large doses of antioxidants is not known, many nutritionists believe that too much Vitamin E can be unhealthy.
Understanding The Various Uses Of Herb PlantsHerb plants are part of the botanical world that provides to the zoological world many benefits. Some of the benefits and uses of herb plants include the use of herbs in cooking, in providing various scents and in the ...
