Drinking three or more cups of coffee a day can trigger the onset of a headache for patients with episodic migraines.
A new study reports caffeine plus another compound found in the waxy coating of coffee beans may help protect the brain against Parkinson's disease.
Study reveals caffeine may be a useful tool to study information and cognitive processing.
Researchers question why many of us are unable to live without our daily cup of coffee. According to a new study, bitter tastes are a natural warning system to protect the body from harmful substances, yet people with heightened ability to detect the bitter taste of coffee learn to associate it with positive things and tend to drink more than those with lower sensitivity. Researchers say this sensitivity is caused by genetic variants.
A taste for black coffee and dark chocolate is possibly a genetic trait, a new study reports. Coffee drinkers who have a genetic variant that reflects faster caffeine metabolism prefer bitter, black coffee. The same genetic variant is found in those who prefer dark chocolate.
