"Rats who were given this specific lactic acid bacterium from their time in the uterus up to adult age put on significantly less weight than other rats," Caroline Karlsson, a researcher in food hygiene at Lund University, Sweden, says in a statement. "Both groups (of rats) ate the same amount of high-energy (high-calorie) food."
The study, published in the British Journal of Nutrition, found the rats, given lactobacilli had a richer and better composition of the bacteria which occur naturally in the intestines.
A healthy gut flora should contain a large proportion of "good bacteria," such as lactic acid bacteria -- found in yogurt, cheese, sauerkraut, pickles, beer, wine, cider, chocolate and other fermented foods -- to keep the inflammation-causing bacteria in check, the study says.
