A balanced diet remains a central pillar in the treatment and prevention of type 2 diabetes. On the occasion of World Food Day, experts from the German Diabetes Center (DDZ) have analysed the scientific evidence on current dietary trends such as intermittent fasting, low-carb and vegan food. According to the study, each of the diets examined can help to improve blood sugar and weight, provided that it is tailored to personal needs and concomitant diseases and can be implemented in the long term.

According to studies, intermittent fasting improves insulin sensitivity in the short term and promotes weight loss, but in the long run it shows no advantages over continuous calorie reduction. The method carries risks for certain patient groups, including the occurrence of hypoglycaemia during insulin therapy, and should only be carried out under medical supervision. A low-carb diet has a positive effect on blood sugar profiles and blood lipid levels, but in the long term the effects are closer to other diets. For people with kidney disease, a strict low-carb diet is unsuitable and the quality of the nutrients supplied is crucial.

A vegan diet can improve metabolism, blood pressure and blood lipids, but requires careful planning to prevent deficiency symptoms. This includes the additional intake of vitamin B12 and a targeted supply of iodine, iron and omega-3 fatty acids. According to current observational studies, a plant-based diet without completely avoiding animal products also reduces the risk of secondary diseases in type 2 diabetes.

The DDZ concludes that no single diet covers all aspects of diabetes treatment. Individual coordination with medical professionals and long-term integration into everyday life are crucial.
