Scientists from Heinrich-Heine-University and the IUF-Leibniz Research Institute for Environmental Medicine in Düsseldorf, Germany, suggest that consuming the amount of caffeine equivalent to four cups of coffee might be enough to protect the cells of the heart.
In the study, the scientists discovered a new enzyme within mitochondria appearing to be relevant to caffeine’s protecting effect: p27. Using the mice models, the researchers found that caffeine protected against heart damage in prediabetic, older, and obese mice.
Lead researchers Judith Haendeler concludes: “These results should lead to better strategies for protecting heart muscle from damage, including consideration of coffee consumption or caffeine as an additional dietary factor in the elderly population.”
According to a new study, conducted by the researchers from Ohio State University, US, coffee is not only can help us more alert and focus but also can enhance interaction within a team. The study was published in the Journal of Psychopharmacology.
For the research, the scientists conducted two related experiments. For the first experiment, seventy-two undergraduate students were recruited. They were randomly split into groups of 5 persons. For the second experiment, the scientists recruited 61 participants.
Having analyzed the received data from both experiments, the researchers found that the volunteers who had drunk regular coffee before participation tended to talk more, but they were also more focused on their given topic of discussion and did not ramble as much as those who had not ingested caffeine.
According to a recent study, published in the Journal of the American Heart Association, drinking more than three cups of coffee every day may reduce the risk of atherosclerosis (clogged arteries). The study was performed by a team from the University of São Paulo in Brazil.
For the study, the researchers analyzed the data of 4,426 adults whose average age was 50 years. The scientists used a food frequency questionnaire to find out how much coffee per day they consumed.
The analysis showed that the adults who consumed at least three cups of coffee a day were less likely to show coronary calcification on the CT scans than those who consumed fewer than one or one to three cups a day.
Coffee is one of the most popular beverages on the planet, having both big fans and haters. Nevertheless, numerous studies from different countries prove that java has many benefits for our health. Here are 7 advantages of drinking coffee:
Drinking one cup of coffee a day linked to 22% lower risk of cirrhosis.
Three to four cups of coffee a day connected to 19% lower risk to die from cardiovascular disease.
One coffee a day associated with 7% lower risk of developing Type 2 diabetes.
At least one cup every day linked to 15% reduced risk of liver cancer and 8% reduced risk of endometrial cancer.
Regular coffee drinkers are approximately 16% less likely to suffer from Alzheimer’s, dementia, or cognitive decline.
At least one cup of coffee a week associated with 15% lower risk of depression.
People who drink at least one cup of coffee a day have 12% lower risk of overall mortality.
According to the research, published in The BMJ, analyzing the findings of 200 studies, three to four cups of coffee every day can be associated with longer life and lower risk of some cancers, diabetes, liver disease, and dementia.
Nevertheless, the scientists say that drinking coffee in pregnancy is linked to harms and can be connected to the slightly increased risk of fracture in women.
The authors conclude that drinking coffee seems safe within usual patterns of consumption, except during pregnancy and in women with higher risk of fracture. At the same time, coffee is often consumed with products rich in refined sugars and unhealthy fats which may independently contribute to adverse health outcomes.
