2. Drinking too much coffee
People who drink a lot of coffee—we’re talking at least three cups a day—have been shown to have lower risks of certain types of cancer, including prostate, skin and oral cancer. Coffee, after all, is rich in the antioxidants and polyphenols that attack cancer-causing free radicals. (As an alternative, red and purple fruits are also full of antioxidants.) Moderate consumption of coffee has also been linked to a decreased risk of Type II diabetes, Alzheimer’s disease and heart disease.
So why do many doctors and naturopaths encourage people to cut back? For one, those who have a genetic mutation that causes them to break down coffee slowly can actually have an increased risk of cardiovascular disease if they sip more than two cups of java a day. Moreover, drinking too much coffee can mean you’re not getting enough water and it can also lead to insomnia and anxiety. So what’s the magic number? Figure out what works better with your own healthy eating, fitness, and sleep routines.
