The study was conducted on people of all ages, all genders, and all different chronic conditions. People who drink three to five cups of coffee each day showed a decreased amount of calcium build-up in their arteries, which gave them lower chances of developing hardening of the arteries, and having heart attacks.
The study was performed on South Koreans, but the researchers see no reason why the results could not be applied to everyone else around the world. The participants drank both caffeinated and decaffeinated coffee, and the results did not change between the two coffee types.

Calcium Build-up

The build-up of calcium in the arteries of the heart is the first sign that the person is going to develop hardening of the arteries. Hardening of the arteries is one of the most frequent causes for heart attacks and heart related deaths.
There are many factors that may play into whether a person develops hardening of the arteries or not. One of the factors is Type II diabetes. People who have type II diabetes are far more likely to develop hardening of the arteries.
High fat diets play a role in whether people develop hardening of the arteries. There is also some correlation of people who have hardening of the arteries and their ancestors. Research indicates that some people have a genetic tendency to have an increased risk of hardening of the arteries.

Who benefits the most from the coffee consumption?

The study compared people of different ages, sexes, people who smoke tobacco, people who were over-weight, people who have diabetes, people with high cholesterol, people with high blood pressure, and many other conditions known to be related to hardening of the arteries. It appears that drinking three to five cups of coffee each day is beneficial to everyone regardless of age, sex, or occupation.
Although caffeinated and decaffeinated coffee both seem to have the same health benefits of reduced calcium build-up, reduced chances of developing type II diabetes, and reduced chances of developing Parkinson’s disease, the things that people put in their coffee can change those results.
The coffee drinkers that receive benefits from the dark liquid do not add large amounts do whipped creams, syrups, artificial sweeteners, creams, or partially hydrogenated oils, to their cups of Joe. You have to limit the amount of additives you put in your daily cups in order for the liquid to be beneficial to your health.

Should Everyone Start Drinking Coffee?

The study does not suggest that everyone start to drink three to five cups of coffee each day. This study has not conclusively proven why the coffee consumption appears to lower some heart related diseases. It does give doctors a reason to look closer into coffee consumption, and their recommendation to their patient’s to reduce this consumption.
