Research just published in Human Reproduction this week looked at girls and their age of menarche and the consumption of sugar-sweetened beverages. It showed girls between ages 9-17 years consuming as few as 1.5 serves per day of drinks such as fruit juice, soft drinks and ice tea were more likely to have an earlier menarche.
"Researchers said a one-year decrease in age at menarche is estimated to increase the risk of breast cancer by 5%." (Medical Observer). The study didn't measure sugary drink consumption in early childhood which is thought to be an important window of exposure.
