New Study Links Caffeinated Coffee To Vision Loss 203

dsinc writes "A new study suggests caffeinated coffee drinkers should limit their intake to reduce their chances of developing vision loss or blindness. According to a scientific paper in Investigative Ophthalmology & Visual Science, heavy caffeinated coffee consumption is associated with an increased risk of developing exfoliation glaucoma (abstract), the leading cause of secondary glaucoma worldwide. 'Scandinavian populations have the highest frequencies of exfoliation syndrome and glaucoma,' said author Jae Hee Kang, ScD, of Channing Division of Network Medicine at Brigham and Women's Hospital in Boston, Mass. 'Because Scandinavian populations also have the highest consumption of caffeinated coffee in the world, and our research group has previously found that greater caffeinated coffee intake was associated with increased risk of primary open-angle glaucoma, we conducted this study to evaluate whether the risk of exfoliation glaucoma or glaucoma suspect may be different by coffee consumption.'"

    Someone should read the article a little better instead of posting some inflaming title... FTFA, "participants who consumed 500 mg/day had a trend toward increased risk of EG/EGS that was not statistically significant". Notice the "not statistically significant" part? Also, " We did not find associations with consumption of other caffeinated products". Way to panic!

    Smoke some Cannabis. It will help with both the nausea and the glaucoma.

    Sorry, their conclusions are just not statistically justified.

    Let me review what they found:
    Compared total caffeine consumption of less than 125 mg/day to greater than 500 mg/day: no significant result
    Compared abstain from caffeinated coffee to greater than 3 cups of caffeinated coffee daily: glaucoma relative risk in the interval 1.09 to 2.54
    Compared consumption of (caffeinated soda, caffeinated tea, decaffeinated coffee or chocolate) to non-consumers of same: no significant result

    That relative risk that they quote as being significant has a confidence interval with a lower end of 1.09; which is only barely above 1.0 (1.0= no effect). So, they studied one particular variety of one particular minor disease (of many health effects). Finding one effect at a trivial level is meaningless.

    You could infuse hot milk with some cannabis, then add it to your coffee!

    So are tomatoes, cheeses, meats, and anything else with a savory flavor.
    Too much of anything is bad for you.
    In moderation, mono-sodium glutamate is no worse for you than salt, sugar, capsaicin, or citric acid.
    And if you live your life avoiding all savory foods, I weep for you.
