Nearly three-quarters of Americans Drink coffee Every day — and now a new study suggests that enjoying it at a certain time of day could lead to some health benefits.
A study conducted by researchers at Tulane University in New Orleans found that drinking coffee in the morning was associated with lower death rates than drinking it later in the day.
The study, published in the European Heart Journal on January 8, analyzed nutritional data for more than 42,000 adults over a nine-year period, according to the results.
Drinking certain types of coffee can provide some health benefits, but additives are important
By comparing adults' coffee consumption and causes of death, the researchers determined that those who drank two or three cups of coffee in the morning had a “significantly” lower risk of death from any cause and death from disease. Cardiovascular diseases Compared to those who did not drink coffee.
Interestingly, this same reduction in risk was not seen for those who drank coffee throughout the day.

“Drink coffee in moderation “It was associated with health benefits,” lead study author Lu Qi, MD, interim chair of the Department of Epidemiology at Tulane University, told Fox News Digital.
“Our study suggests for the first time that the timing of coffee drinking also matters, apart from the quantity – and drinking in the morning shows a stronger relationship with health benefits than drinking it throughout the day.”

Part of the benefits of drinking coffee in the morning involves circadian rhythm, which is the body's internal clock that regulates the wake/sleep schedule, according to Michelle Rothenstein, a New York-based registered dietitian who specializes in… My heart disease.
“Drinking coffee in the morning aligns with a person's circadian rhythm, allowing people to be more focused during the day and allowing them to rest easy at night,” she told Fox News Digital. Rothenstein was not involved in the new study.
“Drinking coffee later in the day can sometimes indicate a Dependence on stimulants “To stay focused and keep working, often at the expense of tackling hunger.”

Dr. Bradley Serwer, a cardiologist and chief medical officer at VitalSolution, a Cincinnati-based company, called the new study “interesting,” noting that “many studies have shown health benefits of caffeine and coffee, but few have evaluated when coffee is consumed.” ”
The new study did not discuss the specific types of coffee consumed or any added ingredients, such as sugar and cream, which could interfere with health benefits. (Istock)
He added: “The authors of this study cannot prove why people drink coffee better in the morning than throughout the day, but they speculate that it may focus on disruption of circadian rhythms leading to poor sleep hygiene.”
“More studies are needed”
Author Qi noted that there are some limitations to the study.
“This is it Observational study“It cannot provide evidence of causation,” he said. “Further studies are needed to validate our findings in other populations.”
“The way coffee is prepared and consumed can affect its heart health benefits.”
Serwer agrees that the study does not prove causality, noting that “the goal of this study is to develop a clinical hypothesis that can be studied further.”
Rothenstein said the study did not discuss the specific types of coffee consumed or any added ingredients, such as sugar and creamer, which could interfere with health benefits.

“How coffee is prepared and consumed can affect its health Heart health benefits“, she said.
“For example, cafestol in unfiltered coffee can raise cholesterol, while saturated creams and syrups add Fats and sugars“.
Caffeine effects may vary
Rothenstein noted that individuals may have genetic differences that can affect their ability to metabolize caffeine, which means the effects of coffee on heart rate and blood pressure can vary from person to person.
