Caffeine isn’t just a “pick-me-up.” When it makes your brain and body feel energized, it also triggers the release of stress hormones. Stress is how we respond to difficult things in our lives. Our bodies react to get us ready for whatever we have to face. Caffeine does the same thing, even though there’s no real challenge in front of us. So we’re stressed out for no reason! And too much stress is bad for us, physically and emotionally.

It’s very likely that your coffee beans have been exposed to pesticides. Pesticides are chemi- cals intended to kill insects and other pests on crops. When you eat these chemicals, though, they can cause cancer.
