Dairy products and metabolic effects in overweight men and women: results from a 6-mo intervention study
Slide 1
The objective was to investigate the effects of an increased intake of dairy products on factors related to the metabolic syndrome in individuals with a habitually low intake.
Slide 2
Subjects
* 121 individuals (80 women and 41 men) * Healthy males or postmenopausal women (30-65 years) * Had to be low habitual consumers of dairy products ( 2 or less products daily) * Meet at least 2 criteria for metabolic syndrome according to the National Cholesterol Education Program Expert Panel
Slide 3
Exclusion
BMI >38 known type 1 diabetes or treated type 2 diabetes glycated hemoglobin (Hb A1c) ≥7.5% known abnormal thyroid hormone concentrations or high thyroid stimulating hormone (TSH) concentrations signs of impaired liver or renal function blood pressure >160/100 mm Hg Individuals with a recent episode of myocardial infarction, stroke, or any other severe pathology that was considered to possibly pose a risk to the individual or to confound the results of the study were all excluded Slide 4
Metabolic syndrome:
-plasma glucose ≥6.1 mmol/L
-serum triglycerides ≥1.7 mmol/L
-HDL cholesterol <1.0 (men) or <1.3 (women) mmol/L
-blood pressure ≥130/85 -waist circumference >94 cm (men) or >88 cm (women)
Slide 5
Intervention
* 6 month randomized, parallel group study * Subjects assigned to milk (intervention) or control group * Intervention group instructed to include 3-5 extra daily sources of dairy products. They could choose from a range of the most common dairy products * Control group retained regular diet * Instructed to not alter lifestyle * Subjects kept diaries and recorded any anomalies in their diet opposed to their group * Dietary records and analyses of a serum biomarker for intake of milk fat were used to verify subjects had significantly increased their milk
