New data suggest that supplementing with vitamin E can help lower rates of asthma, rhinitis and hayfever.
Researchers in Nottingham surveyed the vitamin E intake of a random sample of 2633 adults, aged 18 to 70. Each of the individuals supplied information on their intake of vitamins E and C, magnesium, polyunsaturated fats and other nutrients, via a food frequency questionnaire.
The participants also underwent measurements to determine their sensitivity to grass pollen, cat fur and other allergens, as well as to provide information on the nature of their asthma and hayfever.
On putting all of the information together, the researchers found that those with the highest daily intake of vitamin E were least likely to suffer from allergen sensitive atopic conditions such as asthma, rhinitis and hayfever.
In addition, none of the other nutrients measured appeared to have the same protective effects nor did vitamin E appear to be more effective in combination with any other nutrient (Lancet, 2000; 356: 1573-4).
