Posted November 29, The report is requisitely lengthy to fully document the problem to the scientific community and other demanding reviewers. For time-pressed readers, the first four pages cover the main findings of this report. The issue of whether zinc is involved in the etiology of hypertension has been mired in confusion for years as various animal and human studies employed overdoses of zinc, which actually does induce hypertension.

Although many people take isolated nutrients as antioxidant supplements, they may not be getting the benefits they hope for.

While isolated nutrients have powerful antioxidant abilities in vitro, they rarely have significant antioxidant benefits in vivo.

High antioxidant containing foods have proven benefit in humans in vivo and high antioxidant effects in vitro as well. High antioxidant containing plants and other herbs are recommended for those interested in obtaining true antioxidant benefits.

Introduction We live in a world where free radicals can come from many sources and contribute to deterioration of health. Each day, each cell in the human body endures hits from free radicals—that is about three hundred trillion hits to the body per day!

Antioxidants can inhibit oxidation by giving away an oxygen molecule without requiring much energy. Oxidation is the addition of oxygen or the removal of hydrogen and can be caused by free radicals.

An antioxidant can slow down or even stop the chain reaction of oxidation by giving away an electron without changing its stability. Many believe that since real antioxidants can prevent free radical damage, that perhaps aging and various chronic conditions can, to some degree, be slowed down through the consumption of isolated antioxidant nutrients.

Is this belief correct? It is true that free radical damage to the skin contributes greatly to the aged appearance of the skin [2]. It is true that the consumption of high antioxidant containing foods is associated with a decreased risk of cancer and cardiovascular disease [3]. Yet, it is also true that every large clinical trial, which has used isolated antioxidant supplements, has failed to show benefit for cancer and cardiovascular disease [6,7].

Isolated Form Nutrients It should be understood that some who have concluded that antioxidant vitamins have little positive effect in vivo have normally failed to realize that the chemical forms of antioxidants used in these trials are often not quite the same as the form found in food. However, the differences are more than absorption or antioxidant effectiveness.

Carrots, a food high in betacarotene, do have high antioxidant ability [5,16]. Natural betacarotene, as found in foods, is composed of both all-trans and 9-cis isomers, while synthetic betacarotene is all-trans isomers [17].

Carrots, yellow and green leafy vegetables, and turmeric contain natural betacarotene along with multiple carotenoids. Natural betacarotene was found to significantly decrease serum conjugated diene levels for children exposed to high levels of irradiation, though it is not known if synthetic betacarotene would provide similar benefits [17].

The potential contribution of beta-carotene supplementation to increased risk of lung cancer in smokers has been raised as a significant concern.

Now, although the consumption of both synthetic betacarotene and food betacarotene raise serum vitamin A levels about the same, this obscures the fact that synthetic betacarotene tends to mainly increase serums all-trans betacarotene, while food betacarotene increases other forms as well [19].

In a consumer-directed publication, Stephen Sinatra M.

The bottom line is: Less is more when it comes to beta-carotene. In my opinion, betacarotene in carrots, however, is safer than even Dr. Sinatra suggests there is about 12, i. The reason for this is because betacarotene in carrots is attached to lipoproteins which appear to aid in preventing toxicity.

Vitamin C in foods exists in at least two distinguishable forms with accompanying food factors [22]. Yet, regular ascorbic acid as well as mineral ascorbates are too incomplete to be properly called vitamin C as they do not contain both forms i.

Foods contain both natural forms of vitamin C [22]! Also, foods containing vitamin C are normally less acidic than ascorbic acid. In vitro studies found that food vitamin C has negative oxidative reductive potential [23], while isolated ascorbic acid had positive ORP [24].

Why is that so important? Because while antioxidants can stop free radical damage, only those substances with proper oxidative reductive potential can actually 'clean up' the damage that the free radicals cause.STUDIES ON THE EFFECT OF TEMPERATURE ON THE CATALASE REACTION.

Introduction This article is about red and near-infrared light therapy for healing recent injuries and a few other possible things like fibromyalgia pain, dementia, retinal injuries, and wrinkles. By Dr. Mercola. While there are many different ways to rid your body of accumulated toxins, from detoxifying foods and chemical and/or natural detox agents to saunas, a biological process known as autophagy plays a key term autophagy means "self-eating," and refers to the processes by which your body cleans out various debris, including toxins, and recycles damaged cell components.
