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.

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…)
