The study was published in the European Journal of Nutrition.
The study made use of 3,200 British dietary and health data for people over 16 years of age collected between 2008 and 2016.
Based on the results, participants were more likely to be diagnosed with diabetes the less carbohydrates and the more fat in their diet. A similar relationship was seen in HbA1c levels, which indicate blood sugar balance.
The findings suggest that reducing carbohydrates and adding fats do not help prevent diabetes and may, in the worst case, even expose it to diabetes. Reducing carbohydrates can be detrimental if it also means reducing fruits, vegetables and whole grains. They are rich in, among other things, fiber and antioxidants, which are known to reduce the risk of diabetes.
In the light of current knowledge, the quality of carbohydrates is more important than their quantity. The same applies to fats up to a certain limit.
