Health benefits from moderate coffee consumption
Moderate coffee consumption brings health benefits, according to a new study. According to the researchers, drinking up to three cups of coffee a day is linked to a lower risk of stroke and fatal heart disease.
“To the best of our knowledge, this is the largest study to systematically assess the cardiovascular effects of regular coffee consumption in a population without a diagnosed heart disease,” explains study author Dr. Judit Simon from the Heart and Vascular Center of Semmelweis University Budapest, Hungary, in a current issue Message der European Society of Cardiology (ESC).
Lower risk of stroke
“Our results suggest that regular coffee consumption is safe, and even high daily consumption was not associated with negative cardiovascular events and higher all-cause mortality after a follow-up of 10 to 15 years,” said the scientist.
“In addition, 0.5 to 3 cups of coffee per day were independently associated with a lower risk of stroke, death from cardiovascular disease, and death from any cause.”
Long-term effects of coffee consumption
Although coffee is one of the most widely consumed beverages in the world, little is known about the long-term effects of regular consumption on cardiovascular health, the press release said.
This study, which was presented at the ESC Congress 2021, examined the relationship between coffee consumption and the risk of heart attack, stroke and death.
For the study, data from 468,629 participants from the UK Biobank were analyzed who had no signs of heart disease at the time of recruitment. The mean age was 56.2 years and 55.8 percent were women.
The participants were divided into three groups according to their usual coffee consumption: no regular coffee consumption (22.1 percent), light to moderate consumption (0.5 to 3 cups / day, 58.4 percent) and high consumption (more than 3 percent) Cups / day, 19.5 percent).
The median follow-up was eleven years. The analysis was adjusted for factors that might affect the association with cardiovascular outcomes, including age, gender, weight, height, smoking status, physical activity, high blood pressure, diabetes, cholesterol levels, socioeconomic status, and habitual consumption of alcohol, meat, tea, and fruit Vegetables.
Compared to non-coffee drinkers, light to moderate consumption was associated with a 12 percent lower overall risk of death, a 17 percent lower risk of death from cardiovascular disease, and a 21 percent lower risk of stroke.
In order to investigate the possible underlying mechanisms, the scientists analyzed the relationship between daily coffee intake and cardiac structure and function over a median follow-up period of eleven years.
To do this, they used data from 30,650 participants who had undergone cardiac magnetic resonance imaging (MRI), which is considered the gold standard for assessing cardiac structure and function.
“The imaging analysis showed that the participants with moderate coffee consumption had healthier and better functioning hearts compared to those who did not drink coffee,” said Dr. Simon.
“Our results suggest that coffee consumption of up to 3 cups per day is associated with favorable cardiovascular results,” says the researcher.
She suggests that more studies are needed to explain the underlying mechanisms. According to the expert, the observed benefits can partly be explained by positive changes in the structure and function of the heart. (ad)
