“Feed” Your Skin Antioxidants for a Glowing Complexion

Monday, January 31st, 2011

Although there is no conclusive proof that antioxidants keep skin from aging, experts do agree they have the ability to ‘capture’ free radicals and may protect us from certain diseases. Antioxidant-rich foods can also give us a healthier, glowing complexion.

According to Susan M. Kleiner, R.D., Ph.D, a Seattle-based nutritionist, eating foods rich in antioxidants is best. “There’s no substitute for getting nutrients through food. The body absorbs and assimilates them far better than in supplement form.”

Kleiner suggests following the U.S. Department of Agriculture’s Food Guide Pyramid, and eating three to five servings of vegetables and two to four servings of fruit each day. Choose at least one citrus fruit, such as an orange, a tangerine, or a grapefruit, for vitamin C. To increase beta-carotene intake, eat at least two orange-yellow or leafy green vegetables each day.

Antioxidants Are Found In Broccoli Sprouts

Sunday, June 6th, 2010

A high dose of antioxidants has extremely beneficial effects on the body. Its almost impossible to get too much. First of all, the antioxidants in broccoli sprouts are great for stopping both aging and cell decay, thus resulting in a healthier body. They can even help reduce your risk of cancer.

There are few things as packed with antioxidants as broccoli sprouts, and so many people have jumped on to the current health craze by eating them. It’s not just broccoli sprouts; from Green tea to Vitamin C, antioxidants are the biggest thing in health nowadays. And its no wonder.

Sprouts are a risky proposition for many people. If they are commercially grown, they can carry food-borne diseases which are especially likely to effect the old and very young, as well as people with compromised immune systems. Fortunately, if you grow your broccoli sprouts at home, you can ensure that they are not over-saturated and that you use safe fertilizers which will not infect you with e. coli.

Amazing Antioxidants

Sunday, March 14th, 2010

The prefix ‘anti’ means against, in opposition to, or corrective in nature. In this case, the ‘anti’ in antioxidant describes the effect these chemicals have against oxidants.

Oxidants, usually referred to as ‘free radicals’ are produced as a natural by-product of the millions of biochemical processes undertaken by the body every minute. The same life-giving oxygen that supports all the functions of the body creates these harmful by-products which cause cell damage, usually to DNA, fats and proteins.

Free radicals also enter the body through external influences such as exposure to the sun, pesticides and other kinds of environmental pollution. In addition, their levels are increased by mental and physical stress, the consumption of alcoholic beverages, unhealthy foods, and cigarette smoke.

In much the same way as oxidation causes rust on cars, oxidation inside the body causes a breakdown of cells. If the amount of free radical oxidation in the body is allowed to rise to an unhealthy level, it can result in extensive damage to cellular components and can accelerate the ageing process.

More importantly, it may contribute to a wide range of degenerative illnesses and reduce the body’s ability to deal with other problems, including cardiovascular malfunction, eye disease, and cancer.

Additionally, it may result in a compromised immune system, leading to immunological disorders and a lessening of the body’s ability to heal wounds and overcome infections. Some studies indicate possible links to arthritis and similar chronic conditions.
Antioxidants counter these effects by binding with free radicals before they can cause damage. They then convert them into non-damaging biochemical substances, assisting enormously with the reparation of cellular damage.

Certain antioxidant enzymes are produced within the body. The most well known of these are catalase, superoxide dismutase and glutathione:

Catalase coverts hydrogen peroxide into water and oxygen.

Superoxide dismutase breaks antioxidants down into hydrogen peroxide.

Glutathione is a detoxifying agent, changing the form of toxins so that they are easily eliminated by the body.

Antioxidant Supplement

Thursday, October 22nd, 2009

The focus of research on vitamins these days is how antioxidant supplements may play a role in reducing the risk of cardiovascular disease. Antioxidant supplements – E, C, and beta-carotene (a form of vitamin A) – have potential when it comes to health promotion. However, most data available about such health promoting properties of antioxidant supplements are incomplete. And only up to 30 percent Americans are taking some form of antioxidant supplements.

But what exactly are antioxidants and how important are they?

Antioxidants come in two forms. They can either be vitamins or minerals. They help prevent oxygen from reacting with other chemicals in cells. Such reactions – called oxidation – could lead to cell damage which may result in heart disease and cancer.

Antioxidants can be found in a variety of foods, but they are far more common in fresh fruits and vegetables. A health diet of fresh produce could lead to high levels of antioxidants in your body, which could only mean one thing – less free radicals (those harmful molecules that cause cell damage) and a healthier you.

When antioxidants start to work, they destroy the free radicals or break the chain. You see, here’s what happens when you have lots of free radicals in your body. Because they are highly unstable, these free radicals have the tendency to steal or get electrons from stable molecules and in so doing, make those molecules unstable as well, turning them into free radicals. This becomes a long chain and will go on and on until such a chain in broken. This is where antioxidants come in whose sole function is to break the chain and neutralize free radicals.
