Is Too Much Coffee Bad For You?
People around the world drink billions of cups of coffee.
Studies suggest that drinking a moderate amount of coffee might be good for you.
It may help with some health problems like cancer and Parkinson's disease.
The amount of caffeine in coffee can make you feel better and fight tiredness.
However, too much coffee, especially over 400 milligrams of caffeine a day, can cause problems like headaches and anxiety.
Adding a lot of sugar and cream can also cancel out any health benefits, so it's best to drink coffee black and not too much of it.
Moderate coffee consumption may have health benefits, including reduced inflammation and potential cancer prevention.
Studies show three to four cups of coffee per day may be linked to a reduced risk of breast and liver cancer in post-menopausal women.
Caffeine in coffee may slow the progression of Parkinson's disease.
Overconsumption of caffeine (over 400mg) can lead to headaches, anxiety, and worsen heart conditions.
Adding sugar, cream, and syrups to coffee can diminish the potential health benefits.
