In a review of 177 patients—121 patients with HCV who drank about 2 ¼ cups of coffee a day were found to have reduced levels of liver fibrosis. The results were only found in those who drank caffeinated coffee.
A small study found that people who drank one to three cups of coffee a day had a 29% lower risk of developing liver cancer compared to those who drank 6 cups or less a week.
There are many studies that show a link between the reduction or prevention of certain types of cancers and drinking caffeinated coffee (skin, breast, colon, prostate, uterine, oral). There are also studies that show that caffeinated coffee can lower the risk of diabetes and death.
Now, I am going to burst the bubble! Coffee, specifically caffeine, is a drug (a stimulant). Moreover, with any drug you can have withdrawal: It can take more than eight weeks to withdraw entirely from caffeine—although, caffeine withdrawal is usually just an annoying headache and some light fatigue.
Coffee – 100 mg per cup
Tea – 14 mg to 60 mg per cup
Chocolate – 45 mg in 1.5 oz bar
Most colas (unless they are labeled “caffeine-free”) – 45 mg in 12 oz. drink
Candies, energy drinks, snacks, gum – 40-100 mg per serving
There are many other side effects of caffeine, but I will stop here. However, for most people caffeine in moderation is safe and well-tolerated!
5. Final Thoughts:
What does all of this mean? It is hard to draw concrete conclusions from these studies because you cannot measure what people drink, how it is made and what chemicals are in the coffee. However, there must be something in caffeinated coffee that is contributing to all of these positive outcomes. There are over 1,000 natural chemicals in coffee, and some of these chemicals may be contributing to the caffeine and providing these benefits. Scientists are studying the various chemicals, and we may soon have more concrete information that may lead the way to more potent medications to treat many conditions. In the meantime, it could not hurt to have a cup of Joe—that is if your health allows it.
