The Pros & Cons Of Caffeine
Caffeine is a stimulant and a drug. You know this. Consume too much, and you’ll find yourself addicted and at-risk for associated health problems. You probably know this, too. But at the same time, study after study has shown that moderate consumption of caffeine-rich foods such as coffee, tea, and dark chocolate can help lower your risk of heart disease, diabetes, stroke, and cancer — partially because these foods are all rich sources of disease-fighting antioxidants.
