The team concludes it's all to do with the high glycaemic index of starchy potatoes, which quickly turns into sugars in the body, making blood sugar levels spike.
They said that potatoes have a high glycaemic index compared with other vegetables, so can trigger a sharp rise in blood sugar levels, which could explain the findings.
Refined or processed carbohydrates like white rice and flour have a high glycaemic index, but staple foods that are less processed have a lower glycaemic index.
Beans, lentils and similar foods have a low glycaemic index, which means they are digested slowly and do not cause potentially harmful "spikes" of the hormone insulin.
These can leave you feeling shaky and anxious so steer clear of refined sugars and carbohydrates with a high glycaemic index, which can cause you to crash and burn.
