Because of this Guiseppe Grosso, a nutritional epidemiologist at the University of Catania (Italy), and his colleagues decided to study the effects of coffee on an individual’s overall health. “It’s impossible that we still struggle to decide if coffee is healthy or unhealthy,” Grosso said, and that’s why he and his team decided to take a closer look.
Is Coffee Good For You?
So, what did the research show? Is coffee really good for you?
All in all, Grosso’s team found that coffee can be a part of a healthy diet, but there are still some questions left.
Grosso and his team looked at a collection of studies on the health effect of coffee. In the introduction of their findings, the team recognized that coffee has grown in popularity in recent years and has become the most commonly consumed beverages around the world. However, no one really knows the health implications of being an avid coffee drinker.
Coffee has been associated with a number of health conditions, including high blood pressure. It has also been commonly associated with some psychological disorders, like anxiety.
Despite these associations, Grosso and his team uncovered multiple benefits of drinking coffee. The studies they analyzed took place over the span of 20 years (over 127 studies). Many of them had a broad range of outcomes, but each of them pointed to coffee being beneficial to overall health.
While none of the studies examined by Grosso and his team showed significantly convincing evidence, there was probably evidence to conclude that coffee drinking may be associated with a decreased risk of certain common cancers. People who drink coffee have a 2 to 20 percent risk reduction, depending on the type of cancer. It has shown to help reduce the risk of breast, colorectal, colon, endometrial, and prostate cancers.
Grosso’s team’s review also found coffee drinkers have a reduced risk of cardiovascular disease, Type 2 diabetes, Parkinson’s disease, and an overall lowered death rate as well.
So, Should Everyone Drink Coffee?
No. If your doctor has instructed you to lay off coffee or to not drink it at all, consult them before picking up a coffee habit. Another group of people that should kick the caffeine is pregnant women. Although it can be difficult for an expecting mother to go without caffeine, it can increase the risk of miscarriage.
Another thing that wasn’t quite accounted for in the team’s findings is that the frequency at which the coffee was ingested as well as the amount were not recorded in many of these studies. The caffeine level was also not recorded.
Due to the increasing number of individuals who drink coffee, knowing the health benefits, or consequences, of the beverage, is important. “In other parts of the world, [I have] seen people guzzling much larger volumes of coffee and tea,” Grosso said. “It was absolutely important to know if this was having an effect on health.”
