A recent study says that drinking coffee, whether decaf or regular, could reduce the risk of death.
Researchers began with information from surveys of adults in the United States that asked the amount of coffee they consumed, along with different drinks and food, then they looked at their death rates and illness over the following 20 years.
Ming Ding, a doctoral student in the department of nutrition at the Harvard School of Public Health, was the lead author of the study. The study included numerous participants, more than 50,000 men and 200,000 women.
In the beginning, researchers did not see a clear relationship between drinking coffee and death rates. Individuals who drank anywhere from a cup of coffee or less and three cups a day had 5% to 9% lower risk of dying than individuals who didn’t drink coffee. Individuals who drank more than three cups a day had no benefits.
However, when the researchers looked at coffee intake only between people who said they never smoked, they found that individuals who drank between a cup of coffee or less and three cups a day had 6% to 8% lower risk of dying than individuals who are non-coffee drinkers. Individuals who drank three to five cups or more than five cups had 15% and 12% lower death rates.
It may be true that individuals who drink a considerable measure of coffee drink less soda and therefore have healthier diets overall; soda has been linked to higher rates of death and heart disease.
A percentage of the health benefits connected with drinking coffee are most likely a direct result of the ingredients in coffee, Ding said. Coffee contains chemicals such as lignans and chlorogenic acid that can help control blood sugar and decrease inflammation, both of which can help reduce the risk of heart disease.
With regards to this probability, Ding and her fellow researchers discovered that individuals who drink coffee were about 10 percent less likely to have heart disease as their cause of death. Individuals were also between 9 percent and 37 percent less likely to die of neurological diseases such as Parkinson’s and dementia.
Additionally, the team found that individuals who drank at least a cup of coffee a day had between 20 percent and 36 percent lower rates of suicide. In contrast, individuals who drank less than a cup had 36 percent higher rates.
In spite of the fact that past research has proposed that drinking coffee can protect against cancers such as prostate and liver, the current study did not find lower rates of cancer deaths among java drinkers.
According to Ding, there might not have been a large enough number of deaths due to certain cancers, liver cancer, for example, to be able to see a difference between individuals who drink coffee and individuals who do not.
The study’s findings were published in the journal Circulation.
