After enjoying a greasy meal, many people may drink a cup of coffee. But a Canadian study found that this could double the increase in blood sugar, even from normal to the risk of diabetes.
Researchers from the Department of Human Health and Nutrition Sciences at the University of Guelph in Canada used the "fat cocktail" method to discover the effect of caffeine on blood sugar. The results were published in the Journal of Nutrition (the Journal of Nutrition) in early April.
The researchers first designed a fat-only drink, drank it with the same effect as fat intake, and asked the subjects to drink it to simulate the fat intake of a big meal. Six hours after drinking, each subject drank another glass of sugar water and then checked their glycemic index.
The subjects' blood sugar levels were normal before the test. The results showed that the average blood sugar value of drinking sugar water after a big meal was 32% higher than that of healthy people who drank sugar water only after not eating a big meal.
The researchers further asked the subjects to drink two cups of coffee five hours after the meal and another cup of sugar water an hour later. Blood sugar measurements found that the average blood sugar value was 65% higher than that of healthy people who drank only sugar water without a big meal. It means that caffeine exacerbates the health damage of a high-fat diet and can last for hours. In addition to blood sugar levels, the researchers also tested the release of incretin hormone from the intestines of the subjects, which was also associated with the secretion of insulin to help remove sugar from the blood. They found that after eating fat, secretin also became slow to respond to carbohydrates.
"We can conclude that a combination of fat and caffeine weakens the link between the intestines and the pancreas, making it impossible for subjects to easily remove sugar from the blood and lower blood sugar," study leader Bolton (Marie-Soleil Beaudoin) stressed, especially for people at risk of metabolic diseases and type 2 diabetes.
She suggests choosing low-caffeinated drinks or eating less red meat, processed foods and fast food to reduce saturated fat and improve glucose tolerance (the body's level of glucose metabolism).
