The Los Angeles Times recently reported that medical professionals are calling for labeling standards for caffeine due to its potential effects on the body.
We're all aware of the link between caffeine and sleep (more of the former generally leads to less of the latter) - however, this report also mentions that excess caffeine can exagerrate attention defecit disorder and hyperactivity, increase blood pressure, heart rate and secretion of stress hormones. It can also hamper the body's ability to regulate blood sugar levels. Some research studies have even found that caffeine can harm developing fetuses.
The main argument of the article is the fact that caffeine often appears in foods we wouldn't necessarily expect it to. Caffeine can be found in chocolate bars and even chewing gum. Manufacturers only need to include caffeine on existing labels if it's added to a food or drink - if it occurs naturally in the product, caffeine doesn't need to appear on any ingredient lists.
It's fine to blame coffee on the odd sleepless night or two, but when it comes to long term, chronic insomnia, the cause is often bigger than the consumption of caffeine. I was surprised at just how prevalent caffeine is, though - so perhaps clearer labelling may help people get a better night's sleep. Please share your thoughts - the comments form is below.
