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.
Contrary to popular belief, higher coffee consumption is not associated with an increased risk of arterial stiffness. Drinking up to 25 cups of coffee a day has little impact on heart health.
Researchers report there is no real relationship between how many cups of coffee you drink per day and an increased risk of developing any particular cancer. They also ruled out a link between coffee intake and dying from the disease.
People who drink six or more cups of coffee a day have a 53% increased risk of developing dementia and a higher risk of stroke, a new study reports.
