According to two newly published studies, greater consumption of coffee could lead to a longer life.
One study surveyed more than 520,000 people in 10 European countries, making it the largest study to date on coffee and mortality, and found that drinking more coffee could significantly lower a person’s risk of mortality.
The second study focused on non-white populations. After surveying over 185,000 African-Americans, Native Americans, Hawaiians, Japanese-Americans, Latinos and whites, the researchers found that coffee increases longevity across various races.
Veronica Wendy Setiawan, associate professor of preventative medicine at USC’s Keck School of Medicine, who led the study on nonwhite populations said ‘people who drank two to four cups a day had an 18% lower risk of death compared with people who did not drink coffee. These findings are consistent with previous studies that had looked at majority white populations. Given these very diverse populations, all these people have different lifestyles. They have very different dietary habits and different susceptibilities and we still find similar patterns’.
The new study shows that there is a stronger biological possibility for the relationship between coffee and longevity and found that mortality was inversely related to coffee consumption for heart disease, cancer, respiratory disease, stroke, diabetes and kidney disease.
The study on European countries revealed an inverse association between coffee and liver disease, suicide in men, cancer in women, digestive diseases and circulatory diseases. Those who drank three or more cups a day had a lower risk for all-cause death than people who did not drink coffee.
Both studies were published in the Annals of Internal Medicine.
