It is not uncommon for adult men and women to experience post-meal glucose spikes. Jill A. Kanaley, from the University of Missouri (Missouri, USA), and colleagues enrolled 12 type-2 diabetic men and women, ages 21 to 55 years, in a study to assess whether increased protein consumption at breakfast could stabilize blood levels of glucose and incretin. Subjects ate either a high-protein or high-carbohydrate breakfast, and the lunch included a standard amount of protein and carbohydrates. The researchers found that eating more protein at breakfast lowered individuals’ post-meal glucose levels. Insulin levels were slightly elevated after the lunch meal, which suggested that their bodies were working appropriately to regulate blood-sugar levels. Observing that: “In type 2 diabetic individuals, compared with a high-carbohydrate breakfast, the consumption of a high-protein breakfast meal attenuates the postprandial glucose response and does not magnify the response to the second meal,” the study authors write that: “Insulin, C-peptide, and [glucose-dependent insulinotropic peptide] concentrations demonstrate the second-meal phenomenon and most likely aid in keeping the glucose concentrations controlled in response to the subsequent meal.”
Simple Way to Stabilize Blood Sugar
30 grams of protein at breakfast may help reduce glucose spikes, among type-2 diabetic adults.
