Health Benefits Of Coffee

A 2014 study published by the American Association of Cancer Research found that drinking coffee may help lower your risk for melanoma, which, according to the American Cancer Society, causes most deaths related to skin cancer. In a 2017 study published in Annals of Internal Medicine, researchers found that those who enjoy a daily cup had reduced risks of death from a variety of causes, including stroke. Other studies show the more coffee people drink, the lower their risk of dying of chronic liver disease.

For example, one study found that drinking more than two cups of coffee a day was associated with lower rates of liver scarring and liver cancer among those who had a liver condition (20). Recent studies echo the findings, and they show that people who drink half to three cups of coffee a day have 21% less risk of having a stroke compared with people who drink no coffee at all. In fact, a review found that drinking three to five cups of coffee a day was associated with a 15% lower risk of heart disease (23). One group concluded that men drinking more than four cups of coffee a day may have five times the lower risk of developing Parkinsons disease compared with non-drinkers.

In 2014, researchers collecting data from more than 48,000 individuals found that those who increased coffee intake by at least a cup a day for four years had an 11% lower risk of developing type 2 diabetes compared to those who did not increase consumption. Researchers found that those who had consumed two or more cups of coffee per day following heart attacks had the lowest risk of dying as a result of the attack. In the study, which included more than 185,000 people, scientists found all racial groups--whites, Asians, African-Americans, and Latinos--had a 12% lower incidence of dying of heart disease, cancer, stroke, diabetes, respiratory problems, or kidney disease if they had a cup of coffee daily. Research published in the Journal of the National Cancer Institute found that those who drank four or more cups of coffee daily were 20 percent less likely to get melanoma, a fatal form of skin cancer, during an almost 11-year follow-up, compared with those who did not.

Evidence from the American Institute for Cancer Research concluded that drinking coffee might lower risk for endometrial cancer and liver cancer, but that, according to a systematic review of the larger research literature, was not a risk factor for any studied cancers. Coffee may also provide some other significant health benefits, according to some studies, such as reduced risk for liver cancer, type-2 diabetes, and heart failure. As you saw, coffee has also been shown to lower the chances of developing diabetes, a risk factor for liver cancer and other liver diseases. A raft of studies has suggested that caffeine consumption may lower your risk of developing Parkinsons disease - and a 2012 study published in the American Academy of Neurology showed that a daily dose of caffeine equivalent to the amount found in two eight-ounce cups of black coffee may help to control involuntary movements of those with the disease.
