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 > or =25 kg/m(2)) at baseline but not among leaner individuals (body mass index < 25 kg/m(2)). The adjusted odds of developing IRS (2 or more components) were 72% lower (odds ratio, 0.28; 95% confidence interval, 0.14-0.58) among overweight individuals in the highest (> or =35 times per week, 24/102 individuals) compared with the lowest (<10 times per week, 85/190 individuals) category of dairy consumption. Each daily occasion of dairy consumption was associated with a 21% lower odds of IRS (odds ratio, 0.79; 95% confidence interval, 0.70-0.88). These associations were similar for blacks and whites and for men and women. Other dietary factors, including macronutrients and micronutrients, did not explain the association between dairy intake and IRS. 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.

BACKGROUND: Diet and lifestyle modifications can substantially reduce the risk of type 2 diabetes. While a strong inverse association has been reported between dairy consumption and the insulin resistance syndrome among young obese adults, the relation between dairy intake and type 2 diabetes is unknown. METHODS: We prospectively examined the relation between dairy intake and incident cases of type 2 diabetes in 41,254 male participants with no history of diabetes, cardiovascular disease, and cancer at baseline in the Health Professionals Follow-up Study. RESULTS: During 12 years of follow-up, we documented 1243 incident cases of type 2 diabetes. Dairy intake was associated with a modestly lower risk of type 2 diabetes. After adjusting for potential confounders, including body mass index, physical activity, and dietary factors, the relative risk for type 2 diabetes in men in the top quintile of dairy intake was 0.77 (95% confidence interval [CI], 0.62-0.95; P for trend, .003) compared with those in the lowest quintile. Each serving-per-day increase in total dairy intake was associated with a 9% lower risk for type 2 diabetes (multivariate relative risk, 0.91; 95% CI, 0.85-0.97). The corresponding relative risk was 0.88 (95% CI, 0.81-0.94) for low-fat dairy intake and 0.99 (95% CI, 0.91-1.07) for high-fat dairy intake. The association did not vary significantly according to body mass index (< 25 vs > or = 25 kg/m(2); P for interaction, .57). CONCLUSION:
Dietary patterns characterized by higher dairy intake, especially low-fat dairy intake, may lower the risk of type 2 diabetes in men.
Eating dairy products may reduce the risk of insulin resistance syndrome

Insulin resistance syndrome (IRS) refers to a combination of conditions: obesity, glucose intolerance, high blood pressure, and dyslipidemia (low blood levels of HDL cholesterol and high blood triglyceride levels). IRS increases your risk of developing type 2 diabetes and heart disease. Diet, physical activity, and smoking are all believed to play roles in the development of IRS. Now, research recently published in the Journal of the American Medical Association suggests that overweight people may be able to
reduce their risk of IRS by consuming
dairy products.
unk: :agree: personally I prefer low fat organic milk, taste so much better.....
