Newswise – DALLAS, Feb. 9, 2021 – Dietary information from three large, well-known studies on heart disease suggests that drinking one or more cups of caffeinated coffee may reduce the risk of heart failure, according to a study published today. an Circulation: Heart failure, a journal of the American Heart Association.
Coronary artery disease, heart failure and stroke are among the leading causes of death from heart disease in the US “While smoking, age and high blood pressure are among the most well – known risk factors for heart disease, there are unknown risk factors for heart disease remains, “according to David P. Kao, MD, senior study author, associate professor of cartography and medical director at the Colorado Center for Personal Medicine at the University of Colorado School of Medicine in Aurora, Colorado.
“The dangers and benefits of drinking coffee have been topics of ongoing scientific interest due to their worldwide popularity and frequency of consumption,” said Linda Van Horn, Ph.D., RD, professor and Head of the Department of Nutrition of the Department of Preventive Medicine at Northwestern University’s Feinberg School of Medicine in Chicago, and a member of the Nutrition Committee of the American Heart Association. “Studies reporting associations with outcomes remain relatively limited due to inconsistencies in diet assessment and study methods, as well as sexual problems with self-reported diet inclusion.”
Kao and his colleagues used machine learning through the American Heart Association’s Precision Medicine Platform to analyze data from the original group of the Framingham Heart Study and cited the data face from both the Atherosclerosis Risk in Communities Study and the Study Cardiovascular health to help confirm their results. Each study involved at least 10 years of follow-up, and, together, the studies provided information on more than 21,000 U.S. adult adults.
To analyze the results of caffeinated coffee drinking, researchers classified consumption as 0 cups per day, 1 cup per day, 2 cups per day and? 3 cups a day. Across the three studies, coffee consumption was self-reported, and a standard unit of measurement was not available.
The analysis revealed:
- In all three studies, people who reported drinking one or more cups of caffeinated coffee had an associated risk of long-term heart failure.
- In Framingham Heart and Cardiovascular Health studies, the risk of heart failure decreased over the decades 5-to-12% per cup per day of coffee, compared with no coffee consumption.
- In the Atherosclerosis Risk Study in Communities, the risk of heart failure did not change from 0 to 1 cup per day of coffee; however, it was about 30% lower in people who drank at least 2 cups a day.
- Drinking decaffeinated coffee appeared to have another effect on the risk of heart failure – significantly increasing the risk of heart failure in the Framingham Heart Study. In the Cardiovascular Health Study however; there was no increase or decrease in the risk of heart failure associated with drinking decaffeinated coffee. When the researchers examined this further, they found that consuming caffeine from any source appeared to be associated with a reduced risk of heart failure, and caffeine was at least part of the reason for the benefit. seems to be from drinking more coffee.
“The link between caffeine and reduced risk of heart failure was surprising. Coffee and caffeine are often considered by the general population as ‘bad’ for the heart because people associate them with palpitations, high blood pressure. , etc. The consistent relationship between increased caffeine consumption and decreased risk of heart failure turns that assumption on its head, “Kao said. “However, there is not yet clear enough evidence to suggest increasing coffee consumption to reduce the risk of heart disease with the same intensity and certainty as quitting smoking, losing weight or exercising.”
According to the federal diet guidelines, three to five cups of 8-ounce coffee per day can be part of a healthy diet, but that only refers to simple black coffee. The American Heart Association warns that popular coffee-based drinks such as lattes and macchiatos are often high in calories, added sugar and fat. Moreover, despite its benefits, research has shown that caffeine can also be dangerous if consumed in excess. In addition, children should avoid caffeine. The American Academy of Pediatrics generally recommends that children avoid caffeine-containing beverages.
“While they cannot prove a reason, it is interesting that these three studies suggest that drinking coffee is associated with a lower risk of heart failure and that coffee can be part of a healthy diet pattern if consumed. simple, with no added sugar and high fat dairy products. such a surface, ”said Penny M. Kris-Etherton, Ph.D., RDN, who immediately chaired the Leadership Committee of the American Heart Association’s Cardiometabolic Lifestyle and Health Council, Professor of Nutritional Sciences at Evan Pugh University and senior distinguished professor of nutrition at The Pennsylvania State University, College of Health and Human Development at University Park. “The bottom line: enjoy a coffee in moderation as part of a heart-healthy diet pattern that meets recommendations for fruit and vegetables, whole grains, low-fat / non-fat dairy products, which are also low in sodium, saturated fat and added sugars. It’s also important to be aware that caffeine is a stimulant and if too much can be a problem – causing jitteriness and sleep problems. “
Study limitations that may have influenced the results of the study included differences in the way coffee drinking was recorded and the type of coffee consumed. For example, drip, percolated, French press or espresso coffee varieties; the origin of coffee beans; and no details were provided on instant or unfiltered coffee. There may also be variation in the unit size for 1 cup of coffee (ie, how many ounces per cup). These factors may lead to varying levels of caffeine. In addition, researchers warn that the original studies only reported caffeinated or decaffeinated coffee, so these findings may not apply to energy drinks, caffeinated tea, soda and other food items with caffeine including chocolate.
