Abstract

People who are overweight may be able to lower their risk of insulin resistance by eating dairy products. Insulin resistance is considered a precursor of type 2 diabetes. In a study of 3,157 people who were followed for 10 years, the benefit of dairy products was seen in blacks, whites, men, and women, but not in people with normal weights.<br />Context Components of the insulin resistance syndrome (IRS), including obesity, glucose intolerance, hypertension, and dyslipidemia, are major risk factors for type 2 diabetes and heart disease. Although diet has been postulated to influence IRS, the independent effects of dairy consumption on development of this syndrome have not been investigated. Objective To examine associations between dairy intake and incidence of IRS, adjusting for confounding lifestyle and dietary factors. Design The Coronary Artery Risk Development in Young Adults (CARDIA) study, a population-based prospective study. Setting and Participants General community sample from 4 US metropolitan areas of 3157 black and white adults aged 18 to 30 years who were followed up from 1985-1986 to 1995-1996. Main Outcome Measure Ten-year cumulative incidence of IRS and its association with dairy consumption, measured by diet history interview. Results Dairy consumption was inversely associated with the incidence of all IRS components among individuals who were overweight (body mass index [greater than or equal to]25 kg/[m.sup.2] at baseline but not among leaner individuals (body mass index Conclusions Dietary patterns characterized by increased dairy consumption have a strong inverse association with IRS among overweight adults and may reduce risk of type 2 diabetes and cardiovascular disease.
