Drinking up to three cups of coffee a day can help decrease the risk of stroke and cardiovascular disease, researchers report.
New studies have identified an association between daily high coffee consumption, brain shrinkage and an increased risk of dementia. However, researchers were unable to identify a causal relationship between caffeine consumption and dementia. The study also found moderate coffee consumption was associated with lower dementia risk than high consumption, or abstaining from caffeinated drinks.
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.
Contrary to popular belief, moderate coffee consumption does not increase the risk of cardiac arrhythmias or other heart health problems. Researchers found daily coffee consumption was associated with a 3% lower risk of certain cardiac conditions. Findings add to the growing body of evidence that coffee consumption can help reduce the risk of several health problems including Parkinson's disease and some cancers.
A caffeine jolt may give you a little more energy following a restless night of sleep, but it doesn't necessarily help with boosting cognition. Researchers found that while caffeine helped sleep deprived students to perform better at some simple cognition tests, it had no effect on improving performance on more challenging tasks, like placekeeping tests.
Study reveals a causal genetic link between cardio-health and coffee consumption. Those who subconsciously prefer decaffeinated coffee are more likely to be prone to the adverse effects of caffeine and have risk factors for high blood pressure.
Drinking a cup of strong coffee an hour before exercise, especially in the afternoon, increases fat-burning.
While drinking coffee during the day improves alertness and concentration, especially when a person is sleep-deprived, decreasing consumption six hours prior to sleep diminishes the effects of caffeine on sleep disturbances.
For carriers of the Parkinson's related LRRK2 gene, coffee consumption can help lower the risk of developing symptoms of the disease.
While poor sleep can have some impact on metabolism, drinking coffee immediately after waking can harm glucose control. Strong black coffee consumed before breakfast increased blood glucose response to food by 50%.
Consuming coffee immediately before taking a nap can help reduce sleep inertia in night shift workers who can take a brief nap on the job.
Women aged between 20-44 who drank two to three cups of coffee a day had 3.4% lower adiposity than those who did not consume coffee. Older women who drank four cups per day had an adiposity level 4.1% lower. Overall, total body fat percentage was 2.8% lower in women of all ages who drank two to three cups of coffee a day.
