A nice cup of coffee after dinner is allowed, as long as you have not had a meal with a high fat content. The combination of fat and coffee leads to a higher blood sugar level, resulting in an increased risk of diabetes.
Researcher Marie-Soleil Beaudion, who works at the University of Guelph in Canada, concluded that the blood sugar level of healthy people rises after eating a high-fat meal. This effect doubles by drinking a cup of coffee after dinner. The blood sugar level then rises to a level similar to that of people with an increased risk of diabetes.
Long lasting effect
The results of the study show that saturated fats affect insulin , the substance that lowers blood sugar levels. This effect can last for hours. A prolonged elevated blood sugar level can affect the organs and increases the risk of diabetes.
