Western-style fast food, such as hamburgers, French fries, and pizza, contain a lot of fat. The study found that healthy people’s blood sugar levels will rise after eating a high-fat diet, and if they are accompanied by caffeine drinks, the blood sugar level will double, reaching the blood sugar level of diabetic patients. Studies have shown that saturated fat can hinder the body’s ability to remove sugar from the blood. If taken with coffee, this risk can be further increased and the effect can last for several hours. Long-term high blood sugar levels can cause damage to human organs.
The research director said the new study is significant for people at high risk for metabolic diseases and type 2 diabetes. It is recommended that these people do not take too much caffeine; try to eat less red meat, processed food and Western-style fast food.
