These days, coffee is practically a universal part of our modern workplace condition. Many of us harbor some secret fear that the gallons of brown liquid we’re slurping every day is doing us no good. We cling to scraps of evidence — like this one suggesting coffee contributes to your daily recommended fluid intake — showing that coffee in superhuman amounts is safe. And we pour ourselves another when a new study comes out implying the stuff can make us even healthier than we already are.
Lately, coffee addicts have been winning little victories every few weeks. This time, it’s a double win: a pair of studies suggesting that something about the drink may contain anti-aging and cancer-fighting properties.
One study, presented last week to the Society for Experimental Biology, appears to show an appreciable benefit in the muscle strength of mice who’ve been given caffeine. Researchers from Coventry University examined two main muscles — the diaphragm and a key leg muscle called the extensor digitorum longus — in their test animals before and after the treatment. They noticed a strong link between caffeine intake and better muscle performance among adult mice, with a somewhat weaker relationship for elderly subjects and a small, though still measurable, effect on juvenile mice. The scientists say their findings could be significant for people heading into their golden years, as muscles tend to weaken with age — increasing the likelihood of trips, falls and other mishaps. Who wouldn’t want to be able to maintain their muscle tone by sipping a cup of joe every morning?
The second of the two studies suggests that a moderate intake of caffeinated coffee is associated with a decreased risk for a common skin cancer, basal cell carcinoma. Continue reading
MORE evidence that coffee, particularly among female drinkers, has a positive effect against the most common form of skin cancer worldwide has been released.
Women who drank more than three cups per day of caffeinated coffee saw a 20 percent lower risk of getting basal cell carcinoma (BCC), a slow-growing form of cancer, than those who drank less than a cup per month.
Men who drank the same amount saw a nine percent lower risk, said the research presented at the 10th American Association for Cancer Research International Conference on Frontiers in Cancer Prevention Research in Boston.
“Given the nearly one million new cases of BCC diagnosed each year in the United States, daily dietary factors with even small protective effects may have great public health impact,” said researcher Fengju Song, a postdoctoral fellow in the department of dermatology at Brigham and Women’s Hospital and Harvard Medical School.
“Our study indicates that coffee consumption may be an important option to help prevent BCC.”
The data was derived from the Nurses’ Health Study (Brigham and Women’s Hospital) and the Health Professionals Follow-Up Study (Harvard School of Public Health).
The nurses study followed 72,921 participants from June 1984 to June 2008. The health professionals study tracked 39,976 participants from June 1986 to June 2008.
Basal cell carcinoma was the most frequently diagnosed skin cancer in the groups, totalling 22,786 cases.
The benefits of coffee drinking were not seen against the next two most prevalent types – squamous cell carcinoma (1953 cases) or melanoma (741 cases).
Basal cell carcinoma is a non-melanoma form of skin cancer, and is the most common cancer in the United States. Seventy-five percent of all skin cancers are basal cell carcinomas Continue reading
