Replacing carbohydrate consumption with mixed nuts consumption improves glycaemic control and lipid risk factors among individuals with type 2 diabetes (T2D), according to a new study published in the journal Diabetologia.
For many years there has been a move towards replacing refined carbohydrates with unsaturated vegetable oils. Cohort studies have indicated benefits for lower carbohydrate diets of plant origin in terms of cardiovascular disease (CVD) and diabetes incidence. Specifically, these benefits have been attributed to the use of nuts as a source of vegetable oils.
Data were included for 117 men and postmenopausal women with type 2 diabetes taking oral glucose-lowering agents and with HbA1c between 6.5 and 8.0%. Participants were randomized to full-dose nut diet (477 per 2,000 kcal energy provided as mixed nuts), full-dose muffin diet (471 per 2000 kcal energy provided as whole-wheat muffins, with similar protein content as the nuts), or half-dose nut diet (474 of 2000 kcal energy provided as half portions of nuts and muffins). Post-intervention data were available for 108 participants.
- The full-dose nut diet provided 9.2% greater total energy intake from monounsaturated fat compared with the full-dose muffin diet.
- The full-dose nut diet reduced HbA1c by −0.19% compared with the full-dose muffin diet.
- After the full-dose nut diet there were also reductions in the estimated cholesterol levels in LDL particles with a diameter <255 ångströms and apolipoprotein B.
“Nut intake as a replacement for carbohydrate consumption improves glycemic control and lipid risk factors in individuals with type 2 diabetes,” concluded the authors.
