Effects of co‐ingesting glucose and whey protein on blood glucose, plasma insulin and glucagon concentrations, and gastric emptying, in older men with and without type 2 diabetes
Authors' conclusion
The ability of whey protein to reduce carbohydrate-induced, postprandial hyperglycaemia is retained in older men with T2D compared with those without T2D, and whey protein supplementation may be a useful strategy in the prevention and management of T2D in older people.
Study context
- Population
- Older men with T2D (n = 10, 77 ± 1 years; 31 ± 1.7 kg/m²) and without T2D (n = 10, 78 ± 2 years; 27 ± 1.4 kg/m²)
- Comparison
- Glucose plus whey protein vs glucose, whey protein or control drink
- Outcome
- Blood glucose and plasma insulin over 180 min
- Follow-up
- 180 minutes
Main finding
As reported in the abstract
180 minutes
- GP vs G: P < 0.001
- GP vs G: P < 0.001
- Mixed model analysis
Further findings
- Glucose concentrations higher in men with T2D than without; insulin and glucagon largely unaffected by T2D
- Gastric emptying faster in men with T2D than without
