Can antibiotics be making us fat?

Antibiotics can make us well, but are they also making us fat? Farmers have long used antibiotics to make cows, pigs, and chickens gain weight faster. In a recent article in the journal Nature, scientists found that being exposed to antibiotics early in life may also make children grow fat. The drugs can alter the composition of the bacterial population in the gut during a crucial developmental stage that may have a long-lasting impact. The bacteria play a important role in the digestion and absorption of nutrients in our diet. Antibiotics can damage the delicate balance of good and bad bacteria in the gut. Besides prescriptions, by consuming meat, dairy, and eggs, we are getting a steady stream of antibiotics.
