Whey protein controls after breakfast blood sugar levels
Researchers from Tel Aviv University in Israel studied the effects of pre-breakfast whey protein in 15 participants with well controlled type 2 diabetes. The participants chosen were those on a diet only regimen or taking only metformin and/or sulphonylureas.
The 15 study participants were randomly assigned to have a different drink before their breakfast on two different days. On one day they drank 50g of whey protein in 250 ml of water and on the other day a placebo drink of 250 ml of water. Breakfast was the same on each day, a high-glycaemic index breakfast which would normally raise blood sugar levels rapidly. The researchers reviewed blood glucose levels and levels of the hormones insulin, c-peptide and glucagon-like peptide-1 (GLP-1) over 3 hours following breakfast.
The results showed significant evidence that a whey protein drink may help the bodys metabolism following a high-glycaemic meal. When the participants had whey protein before their breakfast, they experienced 28% reduction in blood glucose levels, compared with the placebo results, over the course of the 3 hour post-breakfast period. Average peak blood glucose 60 minute after breakfast was around 11 mmol/l on the whey protein day and was around 16 mmol/l on the placebo …read more
