Fast food link to obesity confirmed
04/01/2005 - Young adults who eat frequently at fast-food restaurants gain more weight and have a greater increase in insulin resistance in early middle age, according to a large multi-center study published in the January 1 issue of The Lancet.
After 15 years, those who ate at fast-food restaurants more than twice each week compared to less than once a week had gained an extra ten pounds and had a two-fold greater increase in insulin resistance, a risk factor for type 2 diabetes. Diabetes is a major risk factor for heart disease.
Obesity and diabetes are on the rise around the world and the study highlights the value of healthy eating habits.
"It's extremely difficult to eat in a healthy way at a fast-food restaurant. Despite some of their recent healthful offerings, the menus still tend to include foods high in fat, sugar and calories and low in fibre and nutrients," said lead author Mark Pereira, assistant professor of epidemiology at the University of Minnesota .
