Letter: Combatting car fumes

Sir: There are mitigating circumstances surrounding recent findings that every year 6,000 people suffer from heart attacks as a result of traffic pollution.

I, for one, will never have a heart attack despite living in central London. Why such a bold statement? Because, as a vegan, I have a cholesterol level of 122 mg/dl.

The Framingham Heart Study, which has been running for over 40 years, has shown that nobody with a cholesterol level under 150 mg/dl will have a heart attack. Incidentally, as a result of not eating animal products, almost all vegans have cholesterol levels below 150.
