Food cravings are common. The tendency to crave foods high in sugar and fat is well-established in nutritional research. As a food high in both sugar and fat, chocolate is one of the most commonly craved foods in America.

Here are five reasons you might be craving chocolate and what you can do:

Chocolates are made by combining cocoa powder and cocoa butter with sweeteners and other ingredients. Cocoa butter accounts for most of the fat in chocolate. Different types of chocolate have varying concentrations of cocoa powder (often called the cacao percentage). Dark chocolate has the highest concentration of cocoa powder and white chocolate the lowest. Chocolate also contains a variety of other ingredients like sugars, milk powders, and nuts.

Cocoa is naturally bitter. To improve the taste of chocolate, processors add plenty of sugar. Sugar is a type of carbohydrate that your body absorbs quickly. Some people believe that this quick “sugar high” provides a temporary elevation in mood. Most however, suggests that it’s the combination of fat and sugar that make certain foods so addictive.

A plain Hershey’s milk chocolate bar has 24 grams of sugar. Other chocolate bars that contain caramel, nougat, and marshmallow may have even more sugar. For example, a Snickers bar has 27 grams of sugar. Chocolate bars containing more than 75 percent cacao tend to have less sugar (under 10 grams per bar).

Sometimes chocolate cravings can be easily explained: You’re just hungry. When your body is hungry, it craves fast carbohydrates like refined sugars. Unfortunately, most processed chocolate is high on the glycemic index, which means that it gives you a quick, but temporary sugar rush. Once that rush passes, you’ll likely be hungry again.

What to do about it

You can beat your chocolate craving by filling up on something else. Once you aren’t hungry anymore, the intrusive thoughts about chocolate should subside. Look for foods that are low in sugar and high in protein or whole grains. These foods will keep you full longer and prevent a sugar crash.

While chocolate does contain some caffeine, it’s typically not very much. As cacao is processed, its caffeine content decreases. Most processed chocolate candy bars have under 10 mg of caffeine. To put that in perspective: The average cup of coffee has about 85 to 200 mg of caffeine.

Some dark chocolates, however, can contain more caffeine than a can of cola (which has around 30 mg). The higher the cacao content, the higher the caffeine content.

Caffeine stimulates the central nervous system, making you feel more awake and alert. It also affects the levels of certain neurotransmitters in your brain, including dopamine. This may contribute to its addictive nature. For people who never drink caffeinated beverages, the caffeine in chocolate may be enough to provide an energy boost. If you regularly consume caffeine, however, your tolerance to its effects is probably fairly high.
