Consumption of sugar-sweetened beverages has been associated with increased risk of obesity and type 2 diabetes. Now, a new study finds girls who frequently drink such beverages are likely to start menstruation earlier than those who do not consume sugary drinks, potentially putting them at higher risk of breast cancer.
The research team, led by Karin Michels, associate professor at Harvard Medical School in Boston, MA, publishes their findings in the journal Human Reproduction.
1.5 servings of sugary drinks a day linked to starting menstruation 2.7 months earlier
Commenting on the findings, Prof. Michels says:
“Our study adds to increasing concern about the widespread consumption of sugar-sweetened drinks among children and adolescents in the US and elsewhere.
The main concern is about childhood obesity, but our study suggests that age of first menstruation occurred earlier, independently of body mass index, among girls with the highest consumption of drinks sweetened with added sugar. These findings are important in the context of earlier puberty onset among girls, which has been observed in developed countries and for which the reason is largely unknown.”
Findings may indicate an increased risk of breast cancer
