Free Statins with Fast Food could Neutralize Heart Risk
Fast food outlets could provide statin drugs free of1so that customers can reduce the heart disease dangers of fatty food,researchers at Imperial College London 2in a new study.
Statins reduce the3of unhealthy“LDL” cholesterol in the blood. A wealth of trial data has proven them to be highly effective at lowering a person's heart attack4.
In a paper published in the American Journal of Cardiology,Dr Darrel Francis and colleagues calculate that the reduction in heart attack risk offered by a statin is5to offset the increase in heart attack risk from6a cheeseburger and drinking a milkshake.
Dr Francis,from the National Heart and Lung Institute at Imperial College London,who is the senior author of the study,said:“Statins don't cut out all of the7effects of cheeseburgers and French fries. It's better to avoid fatty food altogether. But we've worked out that in terms of your8of having a heart attack. Taking a statin can reduce your risk to more or less the same9 as a fast food meal increases it.”“It's ironic that people are free to take as many unhealthy condi-ments in fast food outlets as they10,but statins,which are beneficial to heart health,have to be prescribed. It makes sense to make risk-reducing statins available just as easily as the unhealthy condiments that are 11 free of charge. It would cost less than 5 pence per/u>12一not much different to a sachet of sugar.”Dr Francis said.
When people engage in risky behaviours like driving or smoking,they're encouraged to take13that lower their risk,like14a seatbelt or choosing cigarettes with filters.
Taking a statin is a rational way of15some of the risks of eating a fatty meal.
