Four cups of coffee is the perfect amount

A new study, which appeared recently in PLOS Biology, shows that a physiologically-relevant dose of caffeine protects cardiovascular cells from damage. That dosage amount? Approximately four cups.

 

Caffeine has long been associated with a reduced risk of Type 2 Diabetes, stroke, and heart disease. However, the link to these diseases was yet to be discovered. According to researchers Judith Haendeler and Joachim Altschmied, a mitochondrial protein, p27, may be the culprit. The protein is known to protect heart muscles from cell death, helping to repair the muscles after a heart attack. This research overturns the assumption that the elderly should avoid caffeine. This and over 100 studies have shown the beneficial aspects of coffee consumption in decreasing the risk of breast, colorectal, colon, endometrial, and prostate cancers.

 

Another recent study, this time conducted by NIH, showed that coffee consumption is related to a lower risk of all-cause mortality. The sample group included over 400,000 Americans aged 50 to 71. Another multinational study of over 500,000 Europeans confirmed the finding.

 

Coffee, however, should not be seen as a cure-all. Drinking four cups of coffee every day—the magical number—is not enough to give an individual’s sedentary lifestyle a pass. Regular exercise and a good diet still matter and may indeed be intervening variables in some of these studies. However, the shown statistical significance proves coffee’s ability to improve overall health. If you find yourself needing that fourth cup of coffee to make it to the end of your work day, go ahead and reach for it.

Coffee may come with a cancer warning in California

California maintains a list of chemicals considered to be possible causes of cancer. Unfortunately, new data shows that acrylamide, a chemical created during the coffee bean roasting process, is on that list. In 2010, the nonprofit Council for Education and Research on Toxics filed a lawsuit in the Los Angeles County Superior Court to address the potential risk. The suit targets several nationwide and international companies that make or sell coffee—this includes Starbucks, 7-Eleven, and BP. The organization alleges that the defendants: “failed to provide clear and reasonable warning” that drinking coffee may expose individuals to acrylamide.

 

Under the California Safe Drinking Water and Toxic Enforcement Act of 1986 (known colloquially as Proposition 65), businesses must provide customers with a “clear and reasonable warning” if potentially harmful agents are included in a specific product. The lawsuit claims these particular stores have failed to provide adequate warning, and the organization is demanding that informative signs be posted for convenient reading within the coffee shops.

 

This lawsuit, however, is only one step toward a larger goal. The attorney representing the nonprofit, Raphael Metzger, explained that the organization wants to reduce the amount of this particular chemical to the point where it poses no significant cancer risk. At the time of this posting, at least 13 of the defendants have settled and agreed to provide a warning.
