I almost drove off the road listening to an ad from a law firm urging parents with children with autism spectrum disorder (ASD) to be part of a lawsuit suing baby food manufacturers for causing their child’s condition. According to the ad, the question of what causes ASD has been settled and what remains is for parents to get what is owed them from baby food manufacturers that have been hiding the truth from the public for years
...Let us look at a review article that examined the available studies on this topic:
A 2019 review examined 14 studies that investigated the association between arsenic and 37 studies that examined the association between lead and ASD. The studies:
The studies did not determine causality; they identified a correlation.
- Divided children into two groups – those diagnosed with and those without an ASD diagnosis
- Determined whether there was a statistically significant difference in the measured arsenic or lead levels in the hair, blood, or urine of the two groups of children.
- Out of the 14 studies on arsenic exposure, 8 (53.3%) reported a positive association.
- Out of the 37 studies on lead exposure, 19 (51.3%) reported a positive association....Class action lawsuits are not new in the U.S., but their scientific basis has weakened over the years. The current lawsuits over ASD and baby foods are based on weak scientific evidence of an association, where even the researchers cannot show a consistent association and no evidence that baby foods cause ASD.
