A study has found there is a type of bacteria in the digestive system that craves chocolate. Everyone has microbes in their stomach but people who have chocolate cravings have different colonies of bacteria.
The study was done by finding 11 men who never ate chocolate and 11 men who ate chocolate everyday. All of the men wee healthy, not obese, and were fed the same foods for five days. The researchers examined the byproducts of their metabolism in their blood and urine and found that a dozen substances were different between the two groups. The amino acid glycine levels were higher in the men that ate chocolate. People who ate chocolate also had lower levels of bad cholesterol.
It is known that bacteria interact with what you eat and studies have shown that intestinal bacteria changes when people lose weight. Someday, some types of obesity will be able to be treated by changing the bacteria in the intestines and stomach.
