Mom: Yanely Becceril Garcia Children: Yanely (2). Spots started to appear on her child's face about a year ago, a tell-tale sign of vitamin A deficiency. The supplements erased the spots. "It was a huge relief," she said. Yanely is one of the few people we met who enrolled in college in Mexico City after high school. She wanted to study nutrition, but money problems forced her back home. She doesn't miss the city, though, with its traffic and pollution. "Here it's quiet, and you can see the sky," she said. Yanely said she wants her daughter "to become someone in life, to be better than me."
