Ontario, Canada, Eating foods that contain fat are not necessarily good for the body, but if you consume coffee after eating fatty foods, the negative impact will be greater again.The study conducted by the University of Guelph showed that the combination of fat and caffeine in coffee can be very harmful to the body. Researchers found that healthy people who drink coffee after eating fatty foods increase blood sugar until doubled. The increase in blood sugar is even equivalent to those at risk of diabetes.
"The study tells us that saturated fats can interfere with the body's ability to clean the sugar in the blood, and when combined with caffeine-containing coffee, then the impact could be worse," said Marie-Soleil Beaudoin, who conducted the study along with the professor of University of Guelph, Lindsay Robinson and Terry Graham, as reported by preventdisease, Tuesday (19/04/2011).
According to Beaudoin, the combination of saturated fat and caffeine can make blood sugar stays in for long periods of time, the impact can be very dangerous.
This study is the first study to find out about the influence of saturated fat and caffeine in coffee on blood sugar levels. Studies performed using cocktails (a novel fat cocktail) containing only fat. The drink is specifically designed to enable researchers to accurately mimic what happens to the body when people swallow fat.
In this study, healthy men were asked to drink about 1 gram of fat for each kilogram of beverage weight. Six hours later they were given the next menu that consists of sugar drinks.
As a result, the subject of blood sugar levels rose to 32 percent higher than people who do not mengonsumi fat.
The researchers also tested the effect of caffeinated coffee in combination with fatty foods. For this test, the researchers gave participants caffeinated coffee drinks 5 hours after ingesting the fat. An hour later given a sugar drink.
The results showed that blood sugar levels increased by 65 percent compared with participants who did not consume coffee and fat.
"This shows that the effects of fatty foods combined with a coffee can last for hours. Even the effect can be doubled compared to people who eat fatty foods only," said Beaudoin.
In addition to a blood test blood sugar levels, researchers also saw the effects of gastro-intestinal tract by measuring the incretin hormone released by the intestine after swallowing fat. These hormones signal the pancreas to release insulin to help cleanse the blood of sugar.
"In the end we have found that fatty and caffeinated coffee can destroy the communication between the intestine and pancreas, is why the participants can not clean from their blood sugar easily," said Beaudoin.
According to Beaudoin, the results of this study is very important for people at risk for metabolic disease and type 2 diabetes.
"We've known for years that people with or at risk of type 2 diabetes should limit their caffeine consumption. Drinking decaffeinated coffee is one way to increase one's glucose tolerance. Limit intake of saturated fatty acids found in red meat, processed foods and food fast food is also beneficial, "lid Beaudoin.
The results of this study have been published in the Journal of Nutrition.
