“For example, prior studies have suggested that variants in CYP1A2, (a gene) encoding the enzyme responsible for more than 95 percent of caffeine metabolism, may alter associations of coffee drinking with cardiovascular-related outcomes, with slower caffeine metabolizers having higher risk of developing hypertension (high blood pressure) or having a myocardial infarction (heart attack) relative to their non-drinking counterparts, whereas faster caffeine metabolizers who drink coffee are at no or lower risk of these outcomes.”

Cinnamon actually comes from the bark of a tropical evergreen called the Cinnamomum tree, and it has one of the highest antioxidant contents of any spice, according to research from the Journal of Agricultural and Food Chemistry. It’s been known to reduce inflammation, help lower sugar and triglyceride levels in the blood, soothe nausea, and aid in fat burning. The antiviral and antibacterial properties in the spice are also said to boost your immune system (and ward off colds.) It’s also packed with manganese, iron, calcium.

If you’re working 80 hours a week, getting three hours of sleep a night, and have no energy because you’re living on carb-heavy takeout, drinking coffee non-stop during the day is a problem. It’s not the coffee; it’s the fact that you’re using the coffee as a crutch. Craving a steaming hot cup or two is fine, being totally dependent on coffee to function isn’t.
Coffee is one of the most chemically treated foods in the world (global demand is high, so methods of growing it often are chemical fertilizer-pesticide-herbicide intensive). This is bad for you (since pesticide residues can end up in your cup) and really bad for the planet. High demand and the fact that it’s generally grown in poorer countries also means labor practices are a major issue. Buy organic and fair-trade if and when you can.
Malignant melanomas are the most dangerous and potentially life-threatening form of skin cancer and one of the most common cancer types in the United States. Studies have found that there is potentially as much as a 20 percent lower risk when a person drinks a minimum of four cups of coffee daily. The type of coffee matters here, as the study showed that decaffeinated coffee was not as effective. Studies on non-melanoma cancer and coffee have shown that people were 17 percent less likely to develop the most common form of skin cancer, basal cell carcinoma, if they drank three or more cups of coffee daily.
