Drinking coffee with a high-fat meal 'can raise blood sugar to harmful levels'

Drinking coffee after a high-fat meal can raise your blood sugar to potentially harmful levels, a study has found.

Not only are blood sugar levels increased after a fatty meal, but the rise doubles if the meal is followed by caffeinated coffee, researchers discovered. The study used a specially prepared drink containing molecules of fat, known as lipids, enabling researchers to mimic what happens to the body when fat is ingested.

Healthy men drank about one gram of the fat beverage for every kilo of body weight. Six hours later they were given a sugar drink. Typically when sugar is ingested, the body produces insulin, which takes the sugar out of the blood and distributes it to muscles.

But the researchers, from the University of Guelph in Canada, found fat affected the body’s ability to do this. Blood sugar levels were 32 per cent higher than they were when the men had not ingested the fat cocktail.
