A steamy cup of coffee paired with an indulgent chocolate treat is a match made in heaven. But keep in mind that both coffee and chocolate supply caffeine, which can impact your health in various ways, both good and bad. The table below provides a listing of the average caffeine content of common foods.

Caffeine is a stimulant that reaches peak concentrations within 30 to 60 minutes of consumption and takes four to six hours to wear off. Studies show that caffeine may help prevent sleepiness on the job, help improve athletic endurance, speed reaction time with some tasks, and even suppress appetite moderately.

On the other hand, despite its wonderful aroma and flavour, coffee may not be good for you when it comes to blood pressure, PMS, breast lumps and anxiety. Some studies suggest that caffeine should be completely avoided, while others can go so far as to say that moderate amounts may be better for you than none. Most experts, however, agree that keeping your daily caffeine intake below 400 milligrams is the most prudent approach. This works out to roughly three cups a day of homemade coffee, or just one or two of a gourmet brand. So feel free to enjoy your coffee and chocolate-but don’t overdo it.
