The National Health Service site in the UK has a story about how a new study has urged Diabetes sufferers to quit coffee. The story was also covered by a number of newspapers in the UK.
The newspaper reports that an American study has shown that â€œa daily dose of caffeine raises blood sugar by 8 per centâ€. They go on to say that drinking caffeine may undermine the effects of medication and that simply giving up drinks containing caffeine may be a way of lowering blood sugar.
There are some important points in the article that discusses some limitations of the study, and that there are still some uncertainities of the effects of coffee on diabetics.
