Drinking Coffee Will Make You Desire Sweet Things

If you can't get past the morning without a cup of espresso, you might need to turn away now, because your caffeine addiction could alter your taste buds.

Caffeine works by suppressing the adenosine receptors. These things play a major part in sleep and can affect how you feel during your sleep, which explains why a shot of coffee makes you alert and more energized.

The thing is, it also lower your ability to taste sweet food. Frustratingly, this may make you crave sugar more.

Scientists at Cornell University ran a blind study to test how caffeine affects our sense of taste. The outcomes were published in the Journal of Food Science earlier this month.

The team split the 107 participants into two groups: One was given a sample of decaffeinated coffee spiked with 200 milligrams of caffeine – generally a similar sum you'll find in a strong cup of coffee – while the second part drank decaffeinated coffee.

Interestingly, despite the fact that coffee drink had been sweetened with a similar amount of sugar, those with decaf ranked their coffee sweeter than those who'd had caffeine added.

"When you drink caffeinated coffee, it will change how you find taste – for however long that impact keeps going," says senior author Robin Dando, assistant professor of food science, in a statement. The coffee, nonetheless, did not have an effect on bitter, sour, salty, or umami perception.

That isn't all. Researchers at that point asked participants how alert they felt after drinking the coffee. Individuals from the two groups reported similar levels of alertness. They weren't even ready to work out if they'd been given the decaff or caffeinated coffee.

It appears that act of drinking coffee is enough to produce the alertness we associate with the drink.
