Drinking diet soda while pregnant linked to autism, but only for one gender: Study

Introduction

A recent study conducted by researchers at the University of Texas Health Science Center at San Antonio (UT Health San Antonio) has investigated the potential link between the consumption of aspartame, commonly found in diet sodas, and an increased risk of autism diagnoses in boys. While the study does not establish a causative relationship, it highlights a significant association that warrants caution among pregnant and breastfeeding women.

Understanding the Study

The study, led by Sharon Parten Fowler, PhD, adjunct assistant professor of medicine at UT Health San Antonio, analyzed the reported aspartame consumption of mothers of children diagnosed with autism spectrum disorder. The results were compared to a control group of children with typical neurological development. The findings revealed that mothers of boys diagnosed with autism were three times more likely to report consuming at least one diet soda or an equivalent amount of aspartame per day during their pregnancy or while breastfeeding.

Furthermore, the research team observed that these associations were primarily observed in boys with autism disorder and not in girls or boys with less severe conditions on the autism spectrum. The odds of a boy with autism being exposed to these diet products daily increased with the severity and earlier onset of the condition, as well as the mother’s use of aspartame-sweetened diet sodas and beverages.

Implications for Fetal Development

Although the study has its limitations, such as retrospective data collection and a predominantly male sample, it contributes to a growing body of research that identifies potential health risks associated with the consumption of aspartame during pregnancy. Previous studies have already linked the intake of diet sodas and other diet beverages during pregnancy to increased risks of prematurity and childhood overweight or obesity.

Dr. Fowler explains that sweeteners used in diet beverages have been found in the amniotic fluid and umbilical cord blood, indicating that these substances can pass through the placenta and potentially affect fetal development. Considering the drastically high prevalence of autism, with one in 23 eight-year-old boys in the U.S. being diagnosed with autism spectrum disorder, the consumption rate of diet sodas and sweeteners among pregnant women deserves careful consideration.

Recommendations for Pregnant and Expectant Mothers

Based on the current findings from both human and animal studies, Dr. Fowler recommends that pregnant, nursing, or women planning pregnancy should avoid drinks containing aspartame as a precautionary measure. Instead, she advises choosing water and adding natural flavorings like fruit juice, lemon or orange slices, or crushed mint leaves to enhance taste.

Supporting Research and Expert Opinions

Dr. Robert Melillo, a brain and autism researcher, supports the findings of the UT Health San Antonio study. He emphasizes the role of environmental factors in the rising rates of autism and suggests that aspartame may trigger an imbalance of certain neurotransmitters in the brain that are associated with autism. By avoiding diet sodas and aspartame during pregnancy, the risk of developmental disabilities in children may potentially be lowered.

Conclusion

In conclusion, the study conducted by UT Health San Antonio raises a significant warning flag regarding the potential link between aspartame consumption during pregnancy and an increased risk of autism diagnoses in boys. While further research is needed to establish a definitive causal relationship, pregnant women are encouraged to prioritize their own health and the health of their unborn children. By being mindful of their beverage choices and opting for healthier alternatives, pregnant women can take a precautionary measure that may contribute to reducing the risk of developmental disabilities in their children.
