Antioxidant Nutrition – A Guide

nutritional supplements

Antioxidant is a broad term used to describe a group of minerals, vitamins, carotenoids and polyphenols. They protect the body from cell-damaging free radicals. Vitamins A, E, C and the mineral selenium are well known antioxidants. Lutein, lycopene and beta-carotene are carotenoids that have high antioxidant nutrition and give many vegetables and fruits their color. Beta-carotene is found in carrots and pumpkins and is what gives them their vibrant orange color. You can find lutein in leafy green vegetables. It is important in eyesight. Red fruits and vegetables, like tomatoes, contain lycopene. Eating a colorful diet gives you the variety and nutritional value you need.

So why are they called antioxidants? The name represents the mechanism by which they help prevent disease. In humans, a small but significant percentage of oxygen molecules in the body will become electrically charged due to natural cellular activity and/or exposure to environmental factors like tobacco smoke and radiation. The oxygen molecule becomes a “free radical” as it undergoes this process of oxidation. Free radicals are highly reactive as they try to steal electrons from other molecules, including DNA and cellular membranes. This chain reaction of free radicals can damage cells, which may play a role in the development of certain conditions like heart disease and cancer. Antioxidants, however, stop the chain-reaction by giving up electrons and neutralizing free radicals so that they cannot induce any more oxidative damage.

Many studies have shown the link between free radicals and several degenerative diseases associated with aging. Thus, it is possible that antioxidant nutrition can be beneficial in reducing the incidence of cancer, cardiovascular disease, cognitive impairment, Alzheimer’s disease, immune dysfunction, cataracts, stroke, and macular degeneration.

There is an abundance of Vitamin A in liver, dairy and fish. Vitamin C is found in bell peppers and citrus fruits while Vitamin E is plentiful in oils, fortified cereals, seeds and nuts. The mineral selenium can be found in Brazil nuts, meats, tuna and plant foods. You will find lutein in green vegetables like broccoli, Brussels sprouts, peas and kale. Tomatoes, watermelon, pink grapefruit and papaya are all good sources of lycopene. Beta-carotene is abundant in sweet potatoes, carrots and squash. If you are not getting enough in your diet, the next step you may want to consider is nutritional supplements.

You can find more information on antioxidant nutrition by doing a web search or doing some research at your local library. Finding the right combination of nutritional supplements for you may be as simple as arming yourself with the right data. The best source of information may come from a nutritionist. They can evaluate your diet and make suggestions regarding supplementation.

Free Radical Fighter – Alpha Lipoic Acid

Posted on October 27th, 2008 by Healthy in General

nutritional value

You’ve heard of antioxidants and how they neutralize harmful chemicals called free radicals in the body. You may not be aware of an antioxidant that occurs naturally inside every cell of the body and is found in some green vegetables, organ meats, rice bran and Brewer’s yeast. Alpha lipoic acid (or ALA) is produced in small amounts by our bodies. Used in nutritional supplement form, it treats such ailments as diabetic neuropathy, coronary heart disease and other serious illnesses.

What makes ALA unique and gives it nutritional value is that it is both water and fat soluble, unlike the more common antioxidants vitamins C and E, and it appears to be able to recycle and extend the metabolic lifespan of antioxidants such as of vitamin C, glutathione, and coenzyme Q10, and it indirectly renews vitamin E. Vitamin C lessens oxidative stress while glutathione helps detoxify the liver. Coenzyme Q10 helps convert food energy into energy inside every cell while vitamin E helps with nerve conduction.

Alpha lipoic acid helps treat the symptoms of a common complication of diabetes called peripheral neuropathy. By speeding the removal of glucose from the bloodstream, ALA enhances insulin function and reduces insulin resistance. A large number of cases of coronary heart disease and obesity are a direct or indirect result of those two factors. Symptoms such as prickling sensations, numbness, burning and sharply cutting pain are relieved by this very useful nutritional supplement.

Free radical damage is thought to contribute to aging and chronic illness. ALA helps neutralize those harmful chemicals. ALA can cross the blood-brain barrier; a wall of tiny vessels and structural cells, and pass easily into the brain. It is thought to protect brain and nerve tissue by preventing free radical damage and is used to treat Alzheimer’s disease. Because of those reasons, ALA is also used to treat a myriad of other illnesses and diseases like cataracts, hardening of the arteries, hepatitis, glaucoma, multiple sclerosis, high cholesterol levels, and even human immunodeficiency virus (HIV).

Though very few, a small number of side effects have been reported when using alpha lipoic acid as a nutritional supplement. They include muscle cramps, skin rash, tingling or a “pins and needles” sensation, or headache. Because ALA can improve blood sugar control, diabetics who take medication to lower their blood sugar should be monitored by their health care provider when taking ALA. People on thyroid medications should also be under the supervision of their healthcare provider if they take this supplement as it can alter thyroid hormone levels.

Is Lipoic Acid A Powerful Antioxidant?

Posted on October 25th, 2008 by Healthy in General

nutritional value

Lipoic acid or alpha lipoic acid (ALA) is a fatty acid found naturally inside every cell of the body. It is a powerful antioxidant; a substance that neutralizes potentially harmful chemicals called free radicals in the body. Our bodies produce it in very small amounts and it is also found in foods such as spinach, Brewer’s yeast, Brussels sprouts, broccoli, peas, organ meats and rice bran. It converts glucose (or blood sugar) into energy. Let’s take at look at this widely touted supplement.

What makes ALA unique and gives it nutritional value is that it is both water and fat soluble, unlike the more common antioxidants vitamins C and E, and it appears to be able to recycle and extend the metabolic lifespan of antioxidants such as of vitamin C, glutathione, and coenzyme Q10, and it indirectly renews vitamin E. Vitamin C lessens oxidative stress while glutathione helps detoxify the liver. Coenzyme Q10 helps convert food energy into energy inside every cell while vitamin E helps with nerve conduction.

Used to treat a common complication of diabetes called peripheral neuropathy, Lipoic acid speeds the removal of glucose from the bloodstream. It enhances insulin function and reduces insulin resistance, which are the basis of most cases of obesity and coronary heart disease. ALA quickly and greatly reduces the severity and incidence of symptoms like burning and sharply cutting pain, numbness and prickling sensations felt in diabetic neuropathy.

Very few side effects have been reported when taking lipoic acid. A small number of people reported a tingling or “pins and needles” sensation, muscle cramps, headache or skin rash. People with diabetes who are taking medication to lower their blood sugar should take ALA under the supervision of a qualified health professional and have their blood sugar levels monitored as ALA may improve blood sugar control. Some studies have shown that ALA used as a nutritional supplement may alter thyroid hormone levels, so those taking thyroid medications and ALA should be monitored by their healthcare provider.
