New study has been able to demonstrate that both the perception of sweet food and bitter food is changed by enjoying coffee.

‘Coffee impacts short-term taste sensitivity and, consequently, the way we sense and perceive food following coffee intake.
’

In the study, 156 test subjects had their sense of smell and taste-tested before and after drinking coffee. The researchers found no changes tin their sense of smell, but they found that the sense of taste was affected.




"When people were tested after drinking coffee, they became more sensitive to sweetness and less sensitive to bitterness," says an associate professor at Aarhus University Alexander Wieck Fjældstad, who was involved in carrying out the study.
To rule out the possibility that caffeine in the coffee could be a factor, the researchers repeated the experiment using decaffeinated coffee. With the same result.
We are easily affected by sweetness and bitterness
"It’s probably some of the bitter substances in the coffee that create this effect," says Alexander Wieck Fjældstad.

According to the researcher, the study sheds some light on a new aspect of our knowledge about our senses of smell and taste.

According to Alexander Wieck Fjældstad, the results maybe provide us with a better understanding of how our taste buds work.
"More research in this area could have significance for how we regulate the way in which we use sugar and sweeteners as food additives.
Improved knowledge can potentially be utilized to reduce sugar and calories in our food, which would be beneficial for a number of groups, including those who are overweight and diabetes patients," he explains.
