Gut Bacteria Explain Chocolate Cravings

A small study links the type of bacteria living in people's digestive system to a desire for chocolate. Everyone has a vast community of microbes in their guts. But people who crave daily chocolate show signs of having different colonies of bacteria than people who are immune to chocolate's allure.

Kochhar compared the blood and urine of those 11 men, who he jokingly called "weird" for their indifference to chocolate, to 11 similar men who ate chocolate daily. They were all healthy, not obese, and were fed the same food for five days.

The researchers examined the byproducts of metabolism in their blood and urine and found that a dozen substances were significantly different between the two groups. For example, the amino acid glycine was higher in chocolate lovers, while taurine (an active ingredient in energy drinks) was higher in people who didn't eat chocolate. Also chocolate lovers had lower levels of the bad cholesterol, LDL.

The levels of several of the specific substances that were different in the two groups are known to be linked to different types of bacteria, Kochhar said.

Interesting. I wonder what the pharmacological impact of the differing bacteria is. Glad to see there is lots of interest in gut bacteria research these days.
