According to a new research, young girls who frequently consume sugary drinks tend to start their menstrual periods earlier than girls who do not. Team from the Harvard Medical School from US conducted a study to see the relationship between sugar sweetened drinks and the age at which girls have their first period.
They followed 5,583 girls, aged 9-14 years between 1996 and 2001 and found that those who consumed more than 1.5 servings of sugary drinks a day had their first period 2.7 months earlier than those who consumed two or fewer such drinks in a week.
Karin Michels, associate professor, who conducted the research said the main concern is about the childhood obesity but the study suggests that age of first menstruation occurred earlier, independently of body mass index.
Sugary drinkes have a higher glycemic index than naturally sweetened drinks such as fruit juices. High-glycemic foods result in a rapid increase in insulin concentrations in the body.
Higher insulin concentrations can result in higher concentrations of sex hormones and large alterations in the concentrations of these hormones circulating in the body has been linked to periods starting earlier. Excessive caffeine intake has also been linked with earlier periods.
