According to a doctoral thesis published in the British Journal of Nutrition, daily intake of probiotics may help reduce low-level inflammation & prevent obesity.
Researchers at Lund University examined the effect of feeding a lactic bacteria named lactobacilli plantarum HEAL19 in rats. They found rats that consumed the lactobacilli had a richer and better composition of bacteria occurring naturally in the intestines. A healthy gut flora should contain a large proportion of “good bacteria", such as lactic acid bacteria, in order to keep the inflammation-causing bacteria in check.
Caroline Karlsson, a researcher in food hygiene at Lund University said, “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. Both groups ate the same amount of high-energy food."
A 3rd group of rats was given the inflammation-causing E. coli bacteria in their drinking water in addition to the same high-energy food as the other rats. The E. coli supplement led to changes in gut flora and increased body fat.
The researchers noted that certain foods, including yogurt, cheese and olives naturally contain lactobacilli—the type of bacteria most often used as probiotics.
