Fast Food and Metabolic Syndrome
Young adults who eat fast food more than twice a week tend to gain more
weight and have a greater increase in insulin resistance in early middle age
than those who frequent fast-food restaurants less than once a week, according
to a study reported in the January 1, 2005, issue of Lancet.
A group of researchers analyzed data from the Coronary Artery Risk
Development in Young Adults (CARDIA) study, which included more than 3,000
young adults who were 18–30 years of age in 1985–1986. According
to the study, men visited fast-food restaurants more often than women, and
blacks visited more often than whites. After 15 years, those who ate fast food
twice a week or more frequently gained an extra 10 pounds of weight and had
twice the risk of insulin resistance as those who ate fast food less often.
The difference held even when physical activity and other variables were
accounted for.
People need to evaluate how often they eat fast food, and should consider
cutting back, the authors suggest.
