SALT LAKE CITY (ABC 4 News) - A University of Utah study finds sugary sodas can lead to higher levels of estrogen in women.
The recent study published in the American Journal of Clinical Nurtrition followed 259 women over two menstrual cycles and found drinking regular non-diet soda causes higher estrogen levels in women.
“We don't know if having higher levels of estrogen is bad, in our population of women we couldn't detect that their menstrual cycles were any different that women who drank less soda, but I think the real question is what are the long term effects of having higher levels of estrogen?” said Christina Proucznik, PhD, study co-author.
Questions such as whether higher levels of estrogen cause an increase risk for breast or ovarian cancers, she said.
“We don't know for sure what the relationship might be between lifetime higher levels of reproductive hormones and reproductive cancers, it's a very reasonable question to ask,” said Proucznik.
Interestingly, fruit juice which has a high component of sugar did not produce the same result in the women studied leading Proucznik to believe soda is a uniquely dangerous beverage.
“Soda doesn't have any nutritional factors in it, it's basically liquid candy,” she said. “We know that drinking soda is not a great idea for many reasons. It can link to obesity, diabetes and now we have one more piece of evidence that it might be changing the hormones in our bodies.”
