There is more good news for shift workers who rely on caffeine to keep alert while working their unique hours. A panel of experts submitted an advisory report to the U.S. Department of Agriculture and the Department of Health and Human Services. This report will help shape the 2015 Dietary Guidelines for America which are the official government dietary guidelines due out later this year. In it they advised that up to 5 cups (8 oz cup) of coffee or 400 milligrams of caffeine can be consumed daily without any detrimental effect. This is the first time that caffeine has been mentioned in the report which is submitted every five years.
The advisory committee noted that in addition to not being associated with health risks, there is evidence of health benefits such as reducing the risk of developing cardiovascular disease and type 2 diabetes. However, they warned that children and pregnant women should limit their caffeine intake and that caffeine should not be mixed with alcohol. Also, remember that caffeine can disturb your sleep, so drink that last cup at least 6 hours before going to bed.
