What the study doesn't say, by the way, is that coffee is one of the most expensive ways to get health-enhancing nutrients into your body. Typically coffee is mostly water. A much better way to improve your health using tropical plants is to take supplements of Amazon herbs, which can be purchased from a variety of online sources. Another way is to eat nutrient-dense superfoods such as chlorella, spirulina or wheat grass juice. Ounce per ounce, these superfoods are no more expensive than coffee, and yet they pack in probably tens of thousands of times as much nutrition at the molecular level.
Finally, the study doesn't mention that coffee has a variety of highly destructive effects on the human body, too, such as leeching minerals from bones due to coffee's high acidity. Nor does it mention that many people use extremely unhealthy creamers in their coffee: a product often made with hydrogenated oils that are well known to contribute to heart disease. The bottom line? Coffee in the real world, not the lab, is more like a junk food than a health food, and its addiction properties make it a poor choice for people seeking balance and health. And the way most people drink it, coffee probably promotes heart disease.
