Some Natural and Synthetic Antioxidants as Stabilizers of b -Carotene Conversion into Vitamin A S. B. Gomboeva

dioxygenase (CDO) from rat intestinal mucosa was studied.
The activity of CDO decreased in the presence of oxidants.
Antioxidants protected both the substrate and the enzyme.
The extent of the protection depended on the antioxidant type.
The combined injection of antioxidants and b -carotene to animals completely or partially prevented the inhibition of the intestinal CDO which was caused by products of non-enzymatic oxidation of b -carotene.
were found to be the most efficient protectors of b -carotene conversion into retinal.

ABSTRACT: Egg albumen coatings with natural antioxidants fenugreek, rosemary, and vitamin E were evaluated for their antioxidant activity in diced raw and diced cooked poultry breast meat.
These 3 materials were selected for investigation in this coating study because of their history of consumption without adverse health effects and their documented antioxidant activity.
One explanation for the enhanced oxidation inhibition of EAS coating compared to antioxidant coatings is the presence of antioxidants on the surface of the product rather than homogenized throughout the product.
Frozen products showed no evidence of oxidation over a storage period of 6 mo (Table 2).

Mean vitamin C intake and blood levels of vitamin C in this population were higher than that reported in the US.
The positive association between blood levels of lycopene and increased risk of cataract was an unexpected result, which may have been an artifact of analysis.
Tea consumption and the reduced risk of colon cancer - results from a national prospective cohort study.
The authors examined the relationship between tea consumption and risk of colon cancer over 10-20 years of follow-up in two cohorts from the NHANES I Epidemiologic Follow-up study, a probability sample of men and women from the non-institutionalized US population.

1. Understand how to reduce risk for cardiovascular disease.
2. Make changes in their lifestyles that will reduce that risk.
Handouts: "How Are You Doing on Reducing Your Risk for a Heart Attack or Stroke?"
Possible answers: smoking, sedentary lifestyle, too much salt, eating foods full of cholesterol and saturated fat, eating trans fatty acids from foods made with shortening or partially hydrogenated oil, being overweight, being stressed, male gender, having diabetes.
Smoking increases the heart rate and blood pressure.
After just 1 year of not smoking, the risk of a heart attack goes down 50 percent.
Some of you also mentioned that you cut fat from your diet to reduce risk.

Put some lemon juice on the apple as soon as it is cut and it will not darken.
The apple is then protected from free radical activity by antioxidants in the lemon juice.
As we age our self-made supply is inclined to dwindle so we must rely more on antioxidant-rich foods and supplements.
Here are some other techniques to perk up your health.
The above report is a condensation of information on how to stay healthy and enjoy life from my book, Live Younger Longer with these Eleven Keys.
As a self-test, check off how many of these fruits and vegetables, frozen or fresh when in season, you eat regularly (more than two times in a month).

Researchers at the U.S. Department of Agriculture have determined that herbs are higher in antioxidant levels than fruits, vegetables and even spices such as garlic.
Antioxidants have become a synonym for good health in recent years.
This is because antioxidants are a class of components that fight off the charged molecules known as free radicals that cause chemical damage in the human body.
North American Herb and Spice has introduced the world to Oreganol P73 and Oregacyn P73: the most concentrated and effective source of antioxidants, period.

These countries' cuisines often include high levels of fat, which has been shown to be linked to heart disease.
Some studies have shown more deaths from strokes in those groups taking vitamin supplements.
Selenium supplementation was also found to reduce prostate cancer in a small group of men, but again the evidence is not yet strong enough to recommend routine supplementation.
Tomatoes have had a good press recently in relation to the prevention of prostate cancer.
This is because they contain not only vitamins C and E, but also another antioxidant called lycopene.
Soya beans have also been in the news recently due to their anti-cancer potential.

Antioxidants are typically defined as substances that delay or inhibit oxidative damage to a target molecule.
Furthermore, oxidative damage can be defined as the attack upon biological molecules of oxygen-containing free radicals such as superoxide and hydroxyl radicals, as well as the attack of nonradical oxygen derivatives, such as singlet oxygens and ozone.
Proteolytic enzymes exist to hydrolyze oxidatively associated with the antioxidant vitamins---vitamin C; vitamin E; and the precursor to vitamin A, beta carotene.
In addition, we find that the general inherent antioxidant defenses are commonly insufficient to repair or replace all of the oxidative damage.
Alpha-lipoic acid is a naturally occurring antioxidant; however, marketed supplements containing this antioxidant generally include the synthetic racemic mixture of the active and inactive enantiomers.

If you're adding berries to your diet only as an immune enhancer during cold and flu season, you may be missing out on berries' big benefits.
Berries, like many other fruits and vegetables, contain potent antioxidants that fight free radicals, molecules created during the cellular process of converting oxygen to energy.
It's been well substantiated that calcium is an essential nutrient for the body.
After protein, fat and carbohydrates, calcium is the body's most abundant nutrient.
Calcium is required to form bones and teeth and is also required for blood clotting, transmission of signals in nerve cells, and muscle contraction.

Oil soluble antioxidants, mainly vitamin E and carotenoids.
Although there is a great multiplicity of methods developed for antioxidant testing, such as the ORAC assay employed in our laboratory, all the methods must be conducted in an aqueous system; therefore none of the methods are suitable for fat soluble antioxidants.
Brunswick Laboratories has overcome these barriers by introducing cyclodextrin as a host to enhance the solubility of fat-soluble antioxidants in aqueous solutions.
