I have stumbled upon the following sentence:
Have your coffee with a snack to allow a slower release of caffeine into your system.
Browsing the internet I could see exactly the same claims, not only in articles, but also in comments and unanswered questions.
There is however no reliable evidence or any kind of proof of it. I'm inclined to believe that it works, the question though is
How exactly does a snack slow down the caffeine release?
Not sure if it's coffee-specific or a general biological way the things work, so I decided to ask here.
