Consuming 4 Cups of Coffee Daily May Help Boost Heart Functions in Elderly

The team found that caffeine was protective against heart damage in pre-diabetic, obese mice, and in aged mice

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)

Coffee Does Not Pose ‘Significant’ Cancer Risk, Says California

It was the first time the state has declared such a brew of chemicals safe despite the presence of carcinogens

California officially gave its blessing to coffee Monday, declaring the beverage does not pose a “significant” cancer risk. The rule, proposed a year ago by regulators, means coffee won’t have to carry ominous warnings that the beverage may be bad for you.

The state took the rare move after a Los Angeles judge found Starbucks Corp. and other companies failed to show that benefits from drinking coffee outweighed risks from a byproduct of the roasting process.

That ruling put the industry in jeopardy of hefty civil penalties and in the position of either developing a process to remove the chemical or warning consumers about the risk of cancer. The chemical in question, acrylamide, is on a list that California says causes cancer, though other groups classify it as a “probable” carcinogen.

Under a law passed more than three decades ago by California voters, products that contain chemicals that cause cancer or birth defects must warn consumers about those risks.

The Office of Environmental Health Hazard Assessment, which implements the law, concluded there was no significant risk after a World Health Organization review of more than 1,000 studies and found inadequate evidence that coffee causes cancer. Further, it concluded coffee reduces the risk of some types of cancer.

“Coffee is a complex mixture of hundreds of chemicals that includes both carcinogens and anti-carcinogens,” said Sam Delson, a spokesman for the agency. “The overall effect of coffee consumption is not associated with any significant cancer risk.”

It was the first time the state has declared such a brew of chemicals safe despite the presence of carcinogens, Delson said. The coffee industry cheered the rule. “This is a great day for science and coffee lovers,” said William Murray, president and chief executive of the National Coffee Association USA. “With this news, coffee drinkers around the world can wake up and enjoy the smell and taste of their coffee without hesitation.”

The Council for Education and Research on Toxics, which successfully sued the coffee industry in a case that has dragged on more than eight years in Los Angeles Superior Court, will challenge the validity of the state’s regulation in court, said attorney Raphael Metzger.

Metzger, who represents the small nonprofit in its lawsuit against Starbucks and about 90 coffee companies, said the regulation was adopted in violation of state law and disregards the statutes the agency is supposed to implement. He said the regulation can’t be applied retroactively to nullify the judge’s ruling. (VOA)
