Drinking four cups of coffee daily might be a healthy addiction, especially in older adults, as it can enhance the function of heart cells as well as help recover from heart attacks, say researchers.

The study, conducted on mice showed that coffee promotes movement of a regulatory protein into mitochondria — cell powerhouse — which then enhances their function to protect cardiovascular cells from damage.

The protein called p27, an inhibitor of the cell cycle, was present in mitochondria in the major cell types of the heart.

In these cells, mitochondrial p27 promoted migration of endothelial cells, protected heart muscle cells from cell death and triggered the conversion of fibroblasts into cells containing contractile fibres — all crucial for repair of heart muscle after myocardial infarction or heart attack, and did so at a concentration that is reached in humans by drinking four cups of coffee, the researchers said.

“Our results indicate a new mode of action for caffeine, one that promotes protection and repair of heart muscle through the action of mitochondrial p27,” said Judith Haendeler from Heinrich-Heine-University’s Medical Faculty in Germany.

“…enhancing mitochondrial p27 could serve as a potential therapeutic strategy not only in cardiovascular diseases but also in improving health span,” she added.

In the study, published in the journal PLOS Biology, the team found that caffeine was protective against heart damage in pre-diabetic, obese mice, and in aged mice.

“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,” Haendeler said. (IANS)

Smelling Coffee May Boost Your Analytical Skills

It's not just that the coffee-like scent helped people perform better on analytical tasks, which was already interesting

If you love the fragrance of coffee, there are high chances of better performance in analytical tasks, a new study has found.

According to the researchers, smelling a coffee-like scent — which has no caffeine in it — has an effect similar to that of drinking coffee, suggesting a placebo effect of coffee scent.

The findings also suggested that the scent of coffee alone may help people perform better on the analytical portion of the Graduate Management Aptitude Test (GMAT) — a computer adaptive test required by many business schools.

“It’s not just that the coffee-like scent helped people perform better on analytical tasks, which was already interesting,” said co-author Adriana Madzharov from the Stevens Institute of Technology in the US.

“But they also thought they would do better, and we demonstrated that this expectation was at least partly responsible for their improved performance,” Madzharov added.

For the study, published in the Journal of Environmental Psychology, the research team administered a 10-question GMAT algebra test in a computer lab to about 100 undergraduate business students.

The participants were divided into two groups. One group took the test in the presence of an ambient coffee-like scent, while a control group took the same test — but in an unscented room.

The researchers found that the group in the coffee-smelling room scored significantly higher on the test.

The team also designed a follow-up survey — conducted among more than 200 new participants — quizzing them on beliefs about various scents and their perceived effects on human performance.

The participants believed they would feel more alert and energetic in the presence of a coffee scent, versus a flower scent or no scent; and that exposure to coffee scent would increase their performance on mental tasks.

The results suggest that expectations about performance can be explained by beliefs that coffee scent alone makes people more alert and energetic.

Previous studies have also suggested that coffee may lessen the risk of heart disease, diabetes and dementia. (IANS)
