More women than men dying of heart disease |
More women than men dying of heart disease
Tue July 07, 2009
According to the most recent data collected on heart-related deaths, 50.5 percent of all deaths caused by heart attack, stroke and heart failure occur in women - slightly higher than the 49.5 percent in men. While this may not seem like a significant difference, Dr. Jack Tu, senior scientist at Toronto's Institute for Clinical Evaluative Sciences says that this represents a "seismic" shift in what has always been considered a disease of middle-aged men.
The reasons for the spike are unclear, but scientists believe there are three key factors. The number of women who smoke is now equal to the percentage of male smokers. There are disparities in the care that women and men receive, primarily because the medical profession has not typically considered women at high risk for heart disease. In addition, symptoms of heart disease in women and men can be quite different - and in fact, the Heart and Stroke Foundation is currently conducting an education campaign that points out these differences.

What Form of Vitamin E is Best? |
What Form of Vitamin E is Best?
By: Dr. George Obikoya
Wednesday, March 11, 2009
There is no denying that vitamin E is extraordinarily beneficial for your body in many different ways. Researchers discovered Vitamin E about eighty years ago, but only in the past few years have we started to appreciate its power as an antioxidant.
Research studies have shown that Vitamin E fights oxygen free radicals, and helps stave off diseases and enhance our overall health. Yet most of us do not get even the recommended daily allowance of 30 International Units. Unless you want to drink two quarts of corn oil and eat a pound of sunflower seeds everyday, the only way to increase your Vitamin E intake is with supplements, preferably in liquid form due to better absorption than pill form. Vitamin E deactivates potentially damaging oxygen free radicals, and prevents heart diseases and other related complications. People with exiting heart disease who take Vitamin E have a 77% lower risk of subsequent (non-fatal) heart attack that those who do not.

Are Tocotrienols Essential? |

Tocopherol-Free Tocotrienol: Are Tocotrienols Essential?
by Dr. Barrie Tan
Lately, interest in a vitamin E product called tocotrienol has been growing. Is it new? What about this sub-component has revitalized interest in this much studied nutrient as it relates to health?
THE DELTA-GAMMA POWERHOUSE
Delta- and gamma-tocotrienols have been proven to be the most potent, and when there is a difference between the two, delta-tocotrienols ranks higher on potency. Thus, with the absence of alpha-tocopherol in a tocotrienol product, you receive the maximum benefit offered by tocotrienols. Their high bio-availabilty have been shown in research on cholesterol, triglycerides, blood hypercoagulation, and cancer.
Just think "delta" and "gamma," especially those tocotrienols as found in UNIQUE E® Tocotrienol. This tocopherol-free tocotrienol from A.C. Grace Company delivers the highest concentrate at 125 mg per beef softgel. Also available is UNIQUE E® Mixed Tocopherols Concentrate - a pure form of high-gamma, high-alpha, beta- and deltatocopherols completely free of fillers of any kind.
TOCOTRIENOLS vs. TOCOPHEROLS?
A mix of both tocopherol forms of vitamin E (especially high gamma and alpha) and tocotrienols are beneficial to the human body. It is highly recommended to take a regimen of pure mixed tocopherols in the morning with your meal, and Annatto tocotrienol taken either at lunch or dinner with your meal. All vitamin E isomers are lipidsoluble supplements and are best taken with a meal, preferably dinner. Absorption is poor when these supplements are taken on an empty stomach.

Human Prostate Cancer Cells |
Gamma-Tocopherol or combinations of vitamin E forms induce cell death in human prostate cancer cells by interrupting sphingolipid synthesis
Contributed by Bruce N. Ames, November 9, 2004
Cancer is one of the leading causes of mortality. Radiation or chemotherapy, although often effective in causing remission, frequently lead to deleterious side effects. It is therefore important to develop effective anticancer agents with high selectivity for malignant cells and low toxicity. We suggest that some vitamin E forms may fall into this category, as well as being beneficial in human disease prevention.
Vitamin E is a generic term for at least eight structurally related molecules: alpha-tocopherol, beta-tocopherol, gamma-tocopherol, delta-tocopherol, alpha-tocotrienol, beta-tocotrienol, gamma-tocotrienol, and delta-tocotrienol. Among them, alpha-tocopherol is the predominant form of vitamin E in plasma and tissues and is the form that has drawn most attention in the past. Benefit from alpha-tocopherol for cancer prevention has been suggested in some studies, but contradictory results exist in both animal and human intervention studies.
Recently, studies by us and others have indicated that other forms of vitamin E appear to have unique properties that are not shared by alpha-tocopherol but may be important to human health.
