Are you a coffee drinker? Well, here’s the truth about your favorite morning beverage. Coffee has been around for a long time and blamed for many ills — from stunting your growth to causing heart disease — but newer research shows that it may actually have health benefits.
Recent studies have generally found no connection between coffee and an increased risk of heart disease or cancer.
If you’re drinking so much coffee that you get tremors, have sleeping problems, or feel stressed and uncomfortable, than obviously you’re drinking too much coffee. But in terms of effects on mortality or risk of chronic diseases, we don’t see any negative effects of consuming up to six cups of coffee a day. Keep in mind that our study and in most studies of coffee, a “cup” of coffee is an 8-ounce cup with 100 mg of caffeine, not the 16 ounces you would get in a grande coffee at a Starbucks, which has about 330 mg of caffeine. Wow!
Some people may still want to consider avoiding coffee or switching to decaf, especially women who are pregnant, or people who have a hard time controlling their blood pressure or blood sugar.
