drink whey protein can control the erratic glucose levels associated with diabetes type 2 -
glucose surges - glucose after meals "points" - can be life threatening for the 29 million Americans with diabetes. Diabetic sugar spikes in the blood have been associated with cardiovascular disease, cancer, Alzheimer's disease, kidney failure and retinal damage. Now a new study from Tel Aviv University, published in Diabetologia , suggests a new way to remove these post-meal glucose surges mortal: whey protein consumption concentrated, found in separate aqueous part milk cheese curds, before breakfast.
According TAU Prof. Daniela Jakubowicz and Dr. Julio Wainstein Unit Diabetes Wolfson Medical Center, Professor Oren Froy of Hebrew University of Jerusalem and Professor Bo Ahr-n of Lund University in Sweden, protein consumption whey before a meal can even keep the need for insulin treatment for diabetics Bay.
"What is remarkable is that the consumption of whey protein before meals reduces blood sugar spikes seen after meals. It also improves insulin response of the body, put it in the same range or even higher than that produced by the new anti-diabetic medications, "said Professor Jakubowicz. "High intake of milk has long been associated with a lower risk for type 2 diabetes and cardiovascular disease, and milk whey protein increases the production of intestinal hormone glucagon-like peptide-1 (GLP -1) which stimulates insulin secretion. This, in turn, reduces the level of glucose in the blood increases after meals. "
a Whey Before Breakfast Cocktail
"We assumed that the GLP-1 production stimulation by consuming whey protein before a meal would improve insulin secretion and have beneficial hypoglycemic effects in type 2 diabetes," said Professor Jakubowicz.
the study was conducted on 15 people with type 2 diabetes well controlled at Wolfson Medical Center. participants were randomized to receive either 50 grams of whey in 250 ml of water or a placebo, followed by a white breakfast standardized high glycemic index of three slices of bread and sweet jelly - a meal designed to produce the maximum peak postprandial blood glucose.
Blood samples were collected 30 minutes before the meal, when the whey protein or placebo drinks were consumed. Other blood samples to evaluate plasma glucose concentration, concentrations of GLP-1 and insulin intact, were taken when breakfast was served and at 15, 30, 60, 0, 0 , 150 and 180 minute intervals after the meal.
the most important meal of the day?
researchers found that glucose levels were reduced by 28 percent after pre-load whey on the 180 minutes after the meal, with a uniform reduction in the early and late phases. precharge whey, insulin and GLP-1 responses were also significantly higher (105 and 141 percent, respectively), producing an increase of 96 percent in the early insulin response.
"The early insulin response which is generally insufficient in type 2 diabetes was significantly higher after whey protein than with placebo, and reduced preload of whey protein significantly elevated blood sugar after breakfast, "said Professor Jakubowicz. "Whey protein may therefore represent a new approach to improve the glucose lowering strategies in type 2 diabetes"
Based on the results of this study, the authors envisage a long-term clinical trial to test the lasting benefits of whey protein consumption for diabetics.
