Antibiotics and obesity. Whether it’s possible that antibiotics plump up humans the same way they do animals, livestock. Plus, we check in on the third anniversary of Japan's Fukushima Nuclear Disaster.
American farmers commonly feed their livestock grain laced with antibiotics because it makes bigger animals. Heavier. Fatter. So what about the antibiotics we humans take – for the ear ache, the strep throat, the sinus infection. Could those make us heavier? Fatter? No one argues that diet and exercise – or lack of it – come first. But could antibiotics be a scale-tipping X-factor in American obesity? This hour On Point: we’re looking at antibiotics and obesity. Plus, we’ll go to Japan to check in on the Fukushima nuclear power plant, three years after its tsunami disaster.

New York Times: The Fat Drug -- "In the last decade, however, scrutiny of antibiotics has increased. Overuse of the drugs has led to the rise of antibiotic-resistant strains of bacteria — salmonella in factory farms and staph infections in hospitals. Researchers have also begun to suspect that it may shed light on the obesity epidemic."
Mother Jones: Can Antibiotics Make You Fat? --"Are we being exposed to tiny levels of antibiotics through residues in the meat we eat—and are they altering our gut flora? It turns out that the Food and Drug Administration maintains tolerance limits for antibiotic residue levels, above which meat isn't supposed to be released to the public."
Nature: Antibiotics in early life alter the murine colonic microbiome and adiposity -- "Antibiotics administered in low doses have been widely used as growth promoters in the agricultural industry since the 1950s, yet the mechanisms for this effect are unclear. Because antimicrobial agents of different classes and varying activity are effective across several vertebrate species, we proposed that such subtherapeutic administration alters the population structure of the gut microbiome as well as its metabolic capabilities."
Reuters: The children of Japan's Fukushima battle an invisible enemy — "Though the strict safety limits for outdoor activity set after multiple meltdowns at the Fukushima Daiichi nuclear plant in 2011 have now been eased, parental worries and ingrained habit mean many children still stay inside. And the impact, three years on, is now starting to show, with children experiencing falling strength, lack of coordination - some cannot even ride a bicycle - and emotional issues like shorter tempers, officials and educators say.
