It's a known fact that burgers and fries are bad for health but researchers say that there is something that doubles the trouble. Eating fast food and topping it up with coffee.
According to a study published in the 'Journal of Nutrition' adding coffee to high-fat meal elevates blood sugar levels.
There is a spike in the blood sugar level after eating a fast food meal but the “spike doubles” if fatty meal is washed down with coffee.
“Ultimately we have found that fat and caffeinated coffee are impairing the communication between the gut and the pancreas, which could be playing a role in why participants couldn’t clear the sugar from their blood as easily.”--Marie-Soleil Beaudoin, lead researcher and PhD student at the University of Guelph in Canada
Effect of fat cocktail studied
To reach the study findings, Beaudoin along with two professors Lindsay Robinson and Terry Graham conducted a study.
They analyzed the effect of saturated fat and caffeinated coffee on blood sugar levels using a lipid-rich beverage.
This fat cocktail enabled researchers to examine what happens in the body when we take in fatty meals.
In the first phase of study, the subjects, who were healthy men, drank the specially formulated fat beverage. Six hours later, they took a sugary drink.
In second phase, the participants drank and fat cocktail, and five hours later they got caffeinated coffee. An hour after that they took sugary drink.
Analyzing the participants, researchers found that in the first phase of the study, men's blood sugar levels rose 32 percent after drinking the fat cocktail, indicating that fatty meal hinders body's ability to clear sugar from blood.
"Having sugar remain in our blood for long periods is unhealthy because it can take a toll on our body's organs,” said Beaudoin.
In phase two, they found that men's blood sugar levels were up 65 percent.
“Ultimately we have found that fat and caffeinated coffee are impairing the communication between the gut and the pancreas, which could be playing a role in why participants couldn’t clear the sugar from their blood as easily,” added Beaudoin.
Decaffeinated coffee recommended
The research findings are specifically important for people suffering from metabolic diseases and type 2 diabetes.
Considering that oral “consumption of lipids and caffeinated coffee can independently and additively decrease glucose tolerance” researchers recommend decaffeinated coffee, as it “one way to improve one's glucose tolerance."
