Scientists have discovered a new type of bacteria in the intestine of infants as they transition from breastfeeding to solid food, according to a study published in the journal Cell.
The bacteria, Bifidobacterium longum, is present in the gut throughout life but is usually found only in babies who have exclusively breastfed for the first six months of their lives, reports the Telegraph.
In the study of 267 infants in Bangladesh, however, researchers found that three different strains of Bifidobacterium longumwhich can use both human milk and fibers from solid foods as energy sourcesexpanded significantly during weaning, which is the "first exposure to the immune system to many new environmental signals from food and bacteria," reports FoodNavi.
The researchers believe the bacteria thrive on the combination of HMOs (Human Milk Oligosaccharides) from human milk and fibers.
Previous research has shown that disruptions in the development of the gut microbiome during infancy can alter immune development and consequently long-term health and wellbeing.
"Weaning is a period of gradual introduction of complementary foods to an infant's diet at six months together with continued breastfeeding (up to two years of age as recommended by WHO)," a researcher says.
