High-protein diet may enhance glycemic control by boosting peripheral insulin levels, finds study
A study published in Diabetes, Obesity, and Metabolism found that a high-protein diet may enhance glycemic control by boosting peripheral insulin levels.
High-protein diets have been recognized as a potential strategy in the nutritional management of type 2 diabetes (T2D). Mycoprotein is a high-fibre, high-protein food ingredient previously shown to improve acute glycaemic control.
We determined whether incorporating mycoprotein into a high-protein vegan diet would improve glycaemic control to a greater extent than an isonitrogenous omnivorous diet in people with T2D.
Seventeen adults (f = 5, age = 58.3 ± 8.3 years, BMI = 32.9 ± 4.7 kg∙m−2, HbA1c = 60 ± 15 mmol∙mol−1) with T2D were randomly allocated to a 5-week eucaloric high-protein (30% energy from protein) diet, either an omnivorous diet (OMNI; 70% protein from omnivorous sources) or an isonitrogenous, mycoprotein-rich, vegan diet (VEG; 50% protein from mycoprotein). Glycaemic control was assessed using a two-step hyperinsulinaemic-euglycaemic clamp (HEC) with D-[6,6-2H2] glucose infusion, a mixed-meal tolerance test (MMTT) and continuous glucose monitoring.
