It rots your teeth. It ages your body as quickly as cigarettes. Now, new research shows young girls who drink too much soda may menstruate earlier.Published in the journal Human Reproduction, the study looked at data from diet questionnaires of 5,583 girls ages nine to 14  who had not had their first period as of the study’s start, the New York Times reported. They studied the girls for a few years, and controlled for other factors that may influence our first period such as weight and physical activity. Researchers found that girls who drank one-and-a-half cans a day of sugar-laden soda or iced tea had their first period 2.7 months earlier, on average, than those who only drank two cans (or less) per week.It’s kind of scary how many things can mess with hormones, contributing to the lower average age of puberty for girls.We can’t always control some environmental factors, but we can keep Coca-Cola away from six-year-olds. Limiting soda intake is an easy way to keep your kids healthy and let their bodies do their thing without any unecessary interference.Related Articles:All the Ways Hormones Are Screwing With Your SkinThe Dangers of BPA
