Vitamin E
Preventing Allergies with Vitamin E
Although several environmental influences, including diet, appear to contribute to allergies (asthma, rhinitis and hayfever), the specific relationship between diet and objective markers of disease has not yet been determined.
Because evidence from animal studies suggests that vitamin E reduces IgE (the allergy-related antibody) responses to allergic stimuli, the authors of this study investigated whether high vitamin E intake is associated with lower IgE serum levels and a reduced frequency of allergen skin sensitization in humans.
Data were derived from a random sample of 2,633 adults (18-70 years old). Subjects reported any history of asthma or hayfever symptoms and completed food frequency questionnaires, providing estimates of dietary intake of vitamin E, vitamin C, magnesium, polyunsaturated fats, and other nutrients. Study participants were also tested for skin sensitivity to various allergens, including grass, pollen and cat fur, and serum IgE levels were measured.
Results showed that increased intake of vitamin E reduced serum IgE levels; this relationship proved incremental, such that each one-milligram increase (up to seven milligrams per day) reduced antibody levels by more than five percent. No additional benefit was noted with daily intake higher than seven milligrams. The authors recommend additional research to investigate the potential utility of vitamin E in the primary and secondary prevention of asthma and allergies.

Vitamin E Protects the Prostate
A Finnish study of 29,133 male smokers, aged 50 to 69, found that the incidence of prostate cancer, as well as the mortality rate from the disease, was significantly reduced among those participants who took vitamin E supplements.
Patients followed one of four daily regimens:
* 50 mg of vitamin E;
* 20 mg of beta-carotene;
* both supplements in combination; or
* an inactive pill.
The incidence of prostate cancer diagnosis was 32% lower among men who took vitamin E alone or in combination with beta-carotene. Additionally, the death rate from the disease was 41% lower among those same patients. This observation suggests that vitamin E may have the potential to prevent one of the most common and deva
