Over 40,000 individuals who took part in the National health and Nutrition Examination survey (1999-2018) in the united states were the subject of the study, which was directed by Dr. Lu Qi, director of the Tulane university Obesity Research Center. Participants provided information regarding their coffee consumption patterns, such as how much they drank and when they did it.
4,295 individuals died over an average follow-up duration of 10 years, with 1,268 of those deaths being attributable to cardiovascular disease. The results showed that:
• coffee drinkers in the morning were 16% less likely to die from any cause.
• In addition, their chance of dying from heart disease was 31% lower than that of non-coffee users.
• Those who drank coffee all day did not exhibit the same decreased risk.
Coffee consumption later in the day may interfere with the body's circadian rhythm, which is our natural 24-hour internal clock, according to Dr. Qi, even if the study does not indicate coffee is the only factor contributing to the health advantages. This disturbance may have an influence on blood pressure, inflammation, and hormone levels, including melatonin, all of which are related to heart health.
"Coffee consumed later in the day may interfere with the body's natural rest cycle, potentially affecting cardiovascular health outcomes," stated Dr. Qi.
It's interesting to note that, in contrast to all-day coffee drinkers, morning coffee consumers in the research also drank less coffee overall and were more likely to drink tea and caffeinated soda.
To determine if moving coffee intake to earlier in the day may be a realistic suggestion for improved heart health, Dr. Qi emphasized the need for more study, especially clinical trials.
As of right now, the results indicate that the earlier in the day you reach for a cup of coffee, the better.
