As promised last week, today’s post concludes our two-week celebration of International Coffee Week by providing an updated table linking coffee/caffeine intake to health effects. The original table appeared in April and you can see that it’s grown quite a bit in only four months. The fly in the ointment continues to be a glaring lack of evidence and information on the effects, if any, of coffee and its ingredients on the various sensory systems. We just do not know how coffee affects hearing, balance, or tinnitus…. but we’d sure like to know.
Coffee and Health
One recent study summarizes the coffee health situation thus:
“…coffee contains diverse biologically active compounds that include caffeine, minerals, and phytochemicals… … coffee may provide as much as half of total antioxidant intake in many settings.”
Table 1 shows the current tally of health effects of coffee/caffeine. If anything’s missing, please send in the information and improve this table. Thanks.
