Drink Coffee for a Healthier You
<<<...So, what's causing these health benefits?
In all likelihood, it's the caffeine and the many naturally occurring antioxidants found in coffee beans. Interestingly, the overall potency of many of these anti-oxidants is increased during the roasting process. Coffee is a significant source of caffeine, and the evidence is very strong that regular coffee consumption reduces risk of Parkinson's disease. The cause of that is directly related to caffeine. As a result, Parkinson's drugs are currently being developed which contain a derivative of caffeine. Caffeine is also what helps in treating asthma and headaches.
For example, a single dose of many popular pain relievers contains up to 120 milligrams of caffeine, the equivalent to two cups of coffee. Coffee also has large amounts of antioxidants such as chlorogenic acid and tocopherols, and minerals such as magnesium. These compounds have been shown to improve insulin sensitivity and glucose metabolism. This increased sensitivity improves one's response to insulin. The result is that a cup of decaf is also more effective than a cup of tea in reducing diabetes (though only half as much as those drinking caffeinated coffee). Finally, research in Europe has shown that the compound trigonelline, which is responsible for coffee's aroma and bitter taste, demonstrates both antibacterial and anti-adhesive properties.
Such properties have a direct effect on dental health, helping to prevent dental cavities from forming. Of course, coffee isn't perfect. In some people, that magic "jolt" of caffeine can result in nervousness, hand trembling, and rapid heartbeat. Further, pregnant women, heart patients, and those at risk for osteoporosis may still be advised to limit or avoid coffee. Nevertheless, the result is that, for people of reasonably normal health, coffee is a reasonably healthy choice and can have health benefits into the future.
