Drinking coffee in the morning may be more strongly associated with a lower risk of death than drinking coffee later in the day, according to a new study led by scientists at Tulane University.
“Previous studies have shown that drinking coffee does not increase the risk of cardiovascular disease, but does increase the risk of some chronic diseases, such as type 2 diabetes,” said Lu Qi, a professor at Tulane University and lead author of the study. appears to be declining.”
“Given the effects of caffeine on our bodies, we wanted to know whether the time of day you drink coffee affects your heart health.”
The study included 40,725 adults who participated in the U.S. National Health and Nutrition Examination Survey (NHANES) between 1999 and 2018.
As part of the study, participants were asked about all the food and drinks they consumed in at least one day, including whether they drank coffee, when and how much they drank it.
The study also included a subgroup of 1,463 people who were asked to complete a detailed food and drink diary for one week.
Approximately 36% of the study participants were coffee drinkers in the morning (mostly coffee before noon), 16% were coffee drinkers throughout the day (morning, afternoon, and evening), and 48% were non-coffee drinkers.
Compared to non-coffee drinkers, those who drank coffee in the morning were 16% less likely to die from any cause and 31% less likely to die from cardiovascular disease.
However, the risk was not reduced for those who drank coffee throughout the day compared to those who did not drink coffee.
People who drank coffee in the morning, both moderate drinkers (2-3 cups) and heavy drinkers (more than 3 cups), benefited from a lower risk.
Those who drank less alcohol in the morning (one glass or less) benefited from a smaller risk reduction.
“This is the first study to test coffee drinking timing patterns and their health effects,” Professor Qi said.
“Our findings show that it’s not just whether or how much you drink coffee that matters, but the time of day you drink it.”
“We don’t usually give advice on timing in dietary guidance, but we might want to think about this in the future.”
“Further research is needed to validate the findings in other populations, and clinical trials are needed to test the potential effects of varying the times people drink coffee.”
