1. Antibiotics in food and as medicine. A recent article in the New York Times confirms suspicions that the antibiotics routinely given to livestock to make them fat do the same thing to people. Antibiotics are thought to fatten by changing gut bacteria to make absorption of nutrients more efficient. In 1974, an experiment was done on several hundred Navy recruits to see if they would gain weight on antibiotics and, after only seven weeks, they did. An experiment was also done, unethically it sounds, on mentally deficient spastic children in Guatemala in the 1950s, reports the Times. The children gained an extra five pounds over a year compared with children who were not given antibiotics. Denmark researchers found babies given antibiotics within six months of birth were more likely to be overweight by age seven. Most researchers blame over-prescription of antibiotics for excessive human exposure; US children get as many as 20 antibiotic treatments while they are growing up, says Martin Blaser, a leading antibiotic researcher at New York University Langone Medical Center. But studies show there are antibiotic residues in US food too, especially in meat and milk, and the government tests for them. That means even if you avoid unnecessary antibiotics from the doctor, you could be getting them from the grocery store.
