But that’s not all. Citing work carried out on the subject, the French Cardiology Federation explains that “the antioxidant capacity of blood increased significantly following the ingestion of a single cup of coffee. This is probably the reason why coffee would have a preventive effect on certain diseases. ».
If the benefits of coffee have been studied many times, researchers from the University of Tulane in New Orleans have been interested in an unprecedented subject: the time of consumption. “Research carried out so far suggests that coffee consumption does not increase the risk of cardiovascular disease and even seems to reduce the risk of certain chronic diseases, such as type 2 diabetes. We wanted to see if the time of the day when we drink coffee had an impact on heart health. »»
They analyzed the data of more than 40,725 adults participating in the US National Health and Nutrition Survey Examination between 1999 and 2018. The participants were questioned about their coffee consumption habits, including the quantity and the time of the day. This information was then crossed with the death registers over a period of nine to ten years.
What are the consequences?
The results revealed that the morning coffee drinkers (before noon) presented a risk of death (all causes) 16 % lower compared to non-coffee non-droops or those who consumed it throughout the day. As for the risk of death by cardiovascular disease, it was reduced by 31 %.
How to explain this difference? “One possible explanation is that coffee consumption in the afternoon or evening can disrupt circadian rhythms and hormone levels such as melatonin,” explain the authors. “This in turn leads to changes in cardiovascular risk factors such as inflammation and increased blood pressure. »»
