In the linked randomised controlled trial (doi:10.1136/bmj.c3337), Coppell and colleagues assess the effect of an intensive dietary intervention on glycaemic control and risk factors for cardiovascular disease in patients who are hyperglycaemic despite optimised drug treatment.1 The authors found that patients who received individualised dietary advice had significantly lower glycated haemoglobin (A1c) (−0.4%, 95% confidence interval −0.7% to −0.1%), body mass index, and waist circumference at six months.
The study adds to the small amount of literature on long term (longer than six months) dietary interventions in patients with type 2 diabetes who are on medication, including insulin, but whose diabetes is relatively poorly controlled, with a haemoglobin A1c of more than 7%. A systematic review of 18 dietary interventions of six months or more in people with type 2 diabetes found no high quality data on the efficacy of the dietary treatment of type 2 diabetes.2 Four recent large studies (three of which have been published since the review) are worth comparing …
