Study finds consuming dairy products may reduce risk of metabolic syndrome

20 March 13

A study published in Food and Nutrition Sciences has investigated whether 18-25 years olds not meeting the dairy recommendation of 3 servings per day are at greater risk for metabolic syndrome.  The paper by Teran-Garcia et al. reports that obesity is increasing in Mexico, reaching similar levels to that found in the USA.  Rates are not just increasing in adults but also in children and the authors speculate that the increased consumption of high calorie beverages may be associated with overweight and obesity in children, with consumption of milk being replaced with these high energy drinks. To determine whether the reduction of dairy consumption and increase in high calorie beverages is associated with increased risk of metabolic syndrome, Teran-Garcia et al. recruited 339 Mexicans involved in the 2009 UP AMIGOS Cohort.  The participants involved in the study, were chosen as they had data available from a health clinic assessment including a complete lipid profile.  The scientists collected data on weight, BMI, waist circumference (WC) and physical activity amongst others.  Blood pressure was measured and fasting blood samples were collected.  Fasting glucose, serum triglycerides, and hypertriglyceridemia were determined.  Metabolic syndrome was defined as having three or more of the following: increased WC, elevated blood pressure, increase fasting glucose, hypertriglyceridemia and low high density lipoprotein-cholesterol (HDL-C).   The participants completed a food frequency questionnaire, recording their intake of commonly consumed foods and beverages in Mexico.  Metabolic syndrome was found in 10.5% of the individuals, with low HDL-C being the most common risk factor followed by increased WC. The prevalence of metabolic syndrome and individual metabolic risk factors between individuals who were not meeting the daily recommendation was 2.6 to 4.1 times higher compared to those meeting the recommendations.  Absolute values of lipid, glucose or other metabolic syndrome parameters were not different between participants meeting and not meeting daily dairy recommendations.  Teran-Garcia et al. report that they did not observe a displacement of milk by sugar sweetened beverages (SSB) in those not meeting dairy recommendations; in fact they found that individuals meeting dairy recommendations consumed slightly more SSB. Those consuming more dairy product consumed more calories, however, there was no difference in BMI or risk factors between those who met recommendations and those who did not.  Although the scientists believe that dairy products guard against obesity and the health problems that accompany extra weight, they are not sure how it happens.  They note that it may be the calcium or it may be the proteins; however previous studies have indicated that increased dairy consumption has been associated with lower body fat in children as young as 2 to 5 years.
