Whey protein helps combat metabolic syndrome

Researchers in a metabolic syndrome study said earlier research showed dairy foods reduced chances of obesity and hoped to find that whey protein from dairy—rich in essential amino acids—could improve metabolic syndrome. Seventy overweight or obese people, aged 18 to 65, took 27 grams of whey protein, casein protein or a glucose placebo twice per day up to 30 minutes before breakfast and evening meals. Researchers asked participants to maintain their normal diet and physical activity. After 12 weeks, compared to placebo, those in the whey protein group had 22 percent lower blood levels of a fat known as triacylglycerol and fasting insulin levels were 11 percent lower.
