V. Reading Comprehension A. If that craving for chocolate sometimes feels like it is comingfrom deep in your gut, that’s because maybe it is. A small studylinks the type of bacteria living in people’s digestive system to adesire for chocolate. Everyone has a vast community of microbes intheir guts. But people who crave daily chocolate show signs ofhaving different colonies of bacteria than people who are immuneto chocolate’s allure. That may be the case for other foods, too. Theidea could eventually lead to treating some types of obesity bychanging the composition of the trillions of bacteria occupying theintestines and stomach, said Sunil Kochhar, co-author of the study.Kochhar compared the blood and urine of those 11 men who don’teat chocolate, whom he jokingly called “weird,” to 11 similar menwho ate chocolate daily. They were all healthy, not obese, and werefed the same food for five days. The researchers examined thebyproducts of metabolism in their blood and urine and found that adozen substances were significantly different between the twogroups. The levels of several of the specific substances that weredifferent in the two groups are known to be linked to different typesof bacteria, Kochhar said. Still to be determined is if the bacteriacause the craving, or if early in life people’s diets changed thebacteria, which then reinforced food choices.
