Studies Show Numerous Health Benefits of Coffee

For many people, a cup of coffee is a good perk-me-up drink that is typically drank in the morning and something for that quick jolt in the afternoon. But, many people don’t know that coffee is a drink that is being found to have numerous health benefits. Numerous studies involving millions of people are coming to some common conclusions about the positive effects of drinking coffee. From lowering risks to type-2 diabetes to having benefits for your liver, studies are confirming prior findings in studies.

It’s important to note that we are talking about just coffee. This means you can’t add 3 tablespoons of sugar and cream and down 5 cups of coffee every day and expect to become super-human. Excess sugar and dairy is not healthy even when added to coffee. Therefore, sugar and diary needs to be eaten in moderation. This article focuses on a black coffee or espresso.

The one thing to remember about coffee is that it comes from a plant. In fact, a coffee bean is actually a seed that grows inside the fruit of a coffee plant. Like all naturally grown things on this earth, there are some vitamins and minerals in these seeds including Riboflavin (Vitamin B2), Pantothenic Acid (Vitamin B5), Manganese, Potassium, Magnesium, and Niacin. Coffee is the number one source of antioxidants for Americans. These antioxidants and the low-calorie count found in coffee may make coffee one of the healthiest things people eat in the U.S. Caffeinated and decaffeinated versions coffee both provide nearly the same levels of antioxidants.

Coffee may reduce risk of type 2 diabetes

Numerous studies are showing that there is a correlation between drinking coffee and the decreased risk of type 2 diabetes.

Another study at the American Chemical Society found that people who drink 4 or more cups of coffee a day reduce their chance of developing Type 2 Diabetes by 50 percent. Numerous other studies have found the similar results with consistent results regardless of age, sex, and weight. The reason for these results is believed to be related to coffee containing minerals such as magnesium and chromium which help the body use insulin and control blood sugar.

Also, a decrease of 22% of developing liver cirrhosis was found in a study by Kaiser Permanente Medical Care Program for alcohol drinkers. In fact, this reduction is larger than that of many medications used for the prevention of disease. Another study found that drinking two or more cups of coffee every day can reduce the risk of death from liver cirrhosis by 66% by decreasing the liver enzyme levels.
