Glycaemic control not improved by high protein

HIGH-protein diets are no more effective than high-carbohydrate diets for improving glycaemic control in people with type 2 diabetes, Australian research shows.

Baker IDI Heart and Diabetes Institute researchers compared a high-protein diet with a high-carbohydrate diet in 99 overweight or obese type 2 diabetes patients over 12 months.

The patients received advice to follow a low-fat diet in which protein made up 30% of total energy, or carbohydrate was 55% of total energy.

There was no difference between the two groups in HbA1c, which fell by 0.23% in the high-protein group and by 0.28% in the high-carbohydrate group in the first three months.

Patients in the high-protein group lost 2.23 kg after 12 months compared with 2.17 kg for those in the high-carbohydrate group, a non-statistically significant difference.

Serum triglycerides, total cholesterol and HDL-cholesterol all improved over time in both groups, but there was no
