There is caffeine in chocolate. For those who must avoid caffeine completely, this may be bad news. However, for those who can have caffeine, the amount in chocolate is not likely to be problematic unless one consumes vast quantities of chocolate on a regular basis. It is also important to remember that caffeine content in chocolate depends on the type of chocolate. Sensitivity to caffeine also varies from one individual to another.
The caffeine in chocolate varies according to the type of chocolate. Semi-sweet chocolate usually contains about 10 milligrams of caffeine per ounce. Milk chocolate usually has at five milligrams or less of caffeine per ounce. Generally, the level of caffeine in chocolate is higher as the chocolate gets darker because dark chocolate contains more cocoa.
In comparison to chocolate, the average cup of coffee contains about ten to fifteen times the amount of caffeine in one ounce of chocolate. Usually coffee contains between 100-150 milligrams of caffeine in an eight-ounce cup. This may vary slightly according to brand and roast style.
The amount of caffeine in tea also can be compared to caffeine in chocolate. Green tea is much lower in caffeine than coffee, containing between 15-40 milligrams per eight-ounce cup. Black tea has an average of 50 milligrams of caffeine per cup. Both green and black tea will have higher levels, depending on how much tea is used and brewing time.
The average Hershey bar is approximately one and a half ounces of milk chocolate. If one eats the whole bar, this translates to consuming about seven and a half milligrams of caffeine. One would have to eat six bars in order to equal the caffeine in strong green tea, and seven and a half bars to equal the caffeine in black tea. To match a cup of coffee, one would have to eat approximately 20 Hershey bars.
White chocolate does not contain caffeine, since those ingredients that make chocolate dark are absent in the white chocolate production process.
Those who are required to avoid or restrict caffeine in their diet due to health concerns ought to consult with their doctor before consuming chocolate.
