NEW YORK (MedscapeWire) Apr 26 ? There may be new truth to the slogan that milk does a body good, at least if that body is overweight. Results from the Coronary Artery Risk Development in Young Adults (CARDIA) study linking dairy intake to reduced risk of insulin resistance syndrome (IRS) are reported in the April 24 issue of The Journal of the American Medical Association.

 

 

"Our study suggests that dietary patterns characterized by increased dairy consumption may protect overweight individuals from the development of obesity and IRS, which are key risk factors for type 2 diabetes and cardiovascular disease," write Mark A. Pereira, PhD, of Children's Hospital and Harvard Medical School in Boston, and colleagues.

 

This population-based, multicenter prospective study involved 3157 black and white adults aged 18 to 30 years followed in the CARDIA study from 1985-1986 to 1995-1996.

 

Among individuals who were overweight, but not among leaner individuals, dairy consumption was inversely associated with the incidence of all IRS components, including obesity, glucose intolerance, hypertension, low high-density lipoprotein cholesterol levels, and high triglyceride levels. Overweight individuals who ate 35 or more dairy servings weekly had a 72% reduction in risk of developing IRS compared with those who consumed fewer than 10 servings weekly. Each daily occasion of dairy consumption lowered odds of IRS by 21%. These associations were similar for blacks and whites and for men and women.

 

Milk intake has decreased significantly over the past 3 decades while the prevalence of obesity and type 2 diabetes has increased. "For most of the past 3 decades, the US Department of Agriculture and the American Heart Association have recommended low-fat diets in the prevention and treatment of cardiovascular disease," the authors write. "Some have questioned these recommendations out of concern that high-carbohydrate consumption might promote IRS."

 

Because this was an observational study, the authors could not rule out residual confounding and could not infer a causal relationship between increased dietary intake and decreased incidence of IRS.
