Effects of Antioxidants in Cellular Aging -part 5-

effects of antioxidants in cellular agingThe body constantly replaces old and worn out cells with new ones and vitamin A is needed to produce healthy replacement cells. The only way to get it was through food of animal origin such as eggs, liver, chicken, milk and dairy products that contain retinol naturally but then discovered another way to get this vitamin and was eating plant foods ue Pertenecena containing carotene carotenes carotenoid family of plants. The body can convert it into vitamin A in the small intestine. Jointly owns the properties of vitamin A and antioxidants that act on free radicals.

It has demonstrated its role in preventing cataracts and their beneficial effect in inflammatory processes and those related to aging. Foods rich in beta-carotene, green vegetables or orange-red-yellow (carrots, spinach, broccoli, squash, tomatoes, etc..), And certain fruits (apricots, cherries, bananas, melon and peach) beta- carotene is especially good for removing oxygen in each molecule it helps to prevent cataracts by eliminating free radicals before they can damage the lens of the eye, preventing the oxidation of LDL (low density lipoprotein), which helps keep normal cholesterol levels and reduces the risk of developing atherosclerosis and heart disease.

Vitamin E (Tocopherol)

Vitamin E is considered “the first line of defense against damage to the membrane of cells that cause oxidation.

It acts as an antioxidant as well because it is soluble in fat and cell membranes are made mostly of fat. Vitamin A penetrates the membranes and remove any free radicals trying to pass. Alpha tocopherol is the most common and active, it works best to eliminate free radicals. Helps prevent or delay heart disease by limiting the oxidation of LDL (bad cholesterol) is also preventing the formation of blood clots that could lead to a heart attack. It also blocks the formation of nitrosamines, which are carcinogens formed in the stomach from nitrites consumed in the diet. (more…)

Carotene and Vitamin A:

When it was discovered vitamin A, was called the “anti-infective agent” is a fat soluble vitamin that fights infection and disease, as first-line barriers helping the epithelial tissue of the body to grow and repair itself. Without enough vitamin A, these cells become stiff, dry and likely to lower our guard favoring the entry of germs into the body. It is essential for healthy eyes.

The body constantly replaces old and worn out cells with new ones and vitamin A is needed to produce healthy replacement cells. The only way to get it was through food of animal origin such as eggs, liver, chicken, milk and dairy products that contain retinol naturally but then discovered another way to get this vitamin and was eating plant foods ue Pertenecena containing carotene carotenes carotenoid family of plants.

effects of antioxidants in cellular agingANTIOXIDANTS

Antioxidants are substances of various kinds, that prevent or slow the oxidative damage by free radicals. For a substance to act as an antioxidant should be able to easily and specifically react with a free radical, neutralizing it and preventing oxidative damage to cells.

This is a group of vitamins, minerals, natural dyes and other plant compounds and enzymes that block the harmful effects of free radicals. Most of the antioxidants found in plant foods, which explains that include fruits, legumes, vegetables or whole grains in our diet is so beneficial.

The first antioxidant defense within the cell is given by antioxidant enzymes such as catalase, glutathione peroxidase and superoxide dismutase. Are endogenous, that is synthesized within the organism and its action depends on the presence of metals such as copper, magnesium, zinc or selenium. (more…)

INTRODUCTION

All our cells are programmed from birth to live a specific period of time, but not all reach as some live for a relatively short time.

The life we are exposed to large numbers of harmful substances that damage our cells, this will lead to the development of chronic diseases that shorten its duration as atherosclerosis, arthritis, diabetes, dementia and cancer, as well as the biological process of aging that is associated with the oxidative damage.

The body has an elaborate defense mechanism in which the vitamins, minerals play an important role. This defense mechanism known as an antioxidant.

Antioxidants come to be substances that react chemically with free radicals making them safe and at the same time prevent their creation that is the cause of cell death. (more…)

- Oxidize:

The natural aging of our body is not nothing but a slow and gradual process of oxidation. Oxygen, essential for life, is also the element that triggers the mechanism by which we oxidize.

In our body occur between 3500 and 5000 chemical reactions per minute, creating energy, protein synthesis or conversion of sugars and other substances in food for the cells produce a number of wastes that result in free radicals, oxidative items that cause aging. (more…)

Natural antioxidants to be younger (II)

On the side there are several minerals that will help us to protect our own cells attack the passage of time. A clear example is zinc, which are conferred upon cell regenerative effects. We found in foods such as meat, fish, whole grains, eggs …

Selenium also has many antioxidant qualities as their consumption is linked to the prevention of certain cancers. The containing foods such as meat, fish, shellfish, eggs … Copper is important consideration for being an important cellular regenerator and stimulating the nervous system. Is found in foods like liver, fish, whole grains, green leafy vegetables …

On the side of the amino acids highlighted one that has an important role in purifying the body. This is the cysteine, which is the body responsible for eliminating all traces of chemicals and heavy metals. We found in meats, eggs, fish and dairy products, and helps mitigate the effects of aging on body substances.

There are other natural substances such as flavonoids that have an important protective function in cells. The can be found in green leafy vegetables, cabbage, red berries, citrus … obtained isoflavones in soy are also another potent antioxidant that helps your body to stay young longer.

Natural antioxidants to be younger (I)

Natural antioxidants

We have repeatedly spoken of the risks that involve free radicals to the body and the importance to protect our cells with natural antioxidants. It is important to know which ones can help in protecting our cells.

A good and proper nutrition can bring us good health. It is important to take this into account and upload your diet of foods that are going to help on the way to protect our cells. Many people take hold of artificial antioxidants and vitamins, when not necessary provided that we obtain through food. It is therefore important that we know we know what nutrients will help.

Vitamins are one of the best-known antioxidants, specifically vitamin C found in fruits and vegetables such as citrus, papaya, strawberries, kiwi … Vitamin E is another important antioxidant found in wheat germ, olive oil , soybeans, green leafy vegetables, nuts … On the other hand include vitamin A or beta-carotene present in vegetables and green leafy vegetables and those that have an orange or yellow.
