Forever chemicals (PFAS) have been linked to gut inflammation in children after early exposure, according to a groundbreaking new study from Mount Sinai. Prenatal and early life exposure to PFAS mixtures is probably linked to higher levels of intestinal inflammation in children, new first-of-its-kind research shows. This inflammation can lead to serious conditions like ulcerative colitis, Crohn’s disease, and even colorectal cancer later in life.
What Are Forever Chemicals?
PFAS (per- and polyfluoroalkyl substances) are a class of at least 16,000 compounds used to make products water-resistant, stain-proof, and non-stick. They are called “forever chemicals” because they do not break down naturally and accumulate in the environment. Common sources include non-stick cookware, waterproof clothing, food packaging, and firefighting foam.

How PFAS Affect Children’s Gut Health
The Mount Sinai study followed mother-child pairs from pregnancy through age 11, checking PFAS levels in maternal blood, umbilical cord blood, and newborn dried blood spots. Researchers found a strong correlation between elevated PFAS levels around birth and markers of intestinal inflammation in children. “The idea that the mom-baby dyads are exposed to these very toxic chemicals this early in the children’s life, and that that leads to later intestinal inflammation, is a very important finding,” said Vishal Midya, a study co-author.
Key Study Findings
- PFAS exposure during pregnancy or early infancy is linked to higher gut inflammation markers in children up to age 11.
- Intestinal inflammation can lead to irritable bowel diseases like Crohn’s disease and ulcerative colitis.
- This is the first study to examine the impact of PFAS on children’s gut health during critical developmental phases.
- PFAS are also linked to cancer, kidney disease, liver problems, immune disorders, and birth defects.
Comparison of PFAS Health Risks
| Health Issue | Linked to PFAS Exposure | Age Group Affected |
|---|---|---|
| Gut inflammation | Yes | Children (prenatal to age 11) |
| Cancer (kidney, testicular) | Yes | Adults |
| Immune system disruption | Yes | All ages |
| ADHD | Yes | Children |
How to Reduce PFAS Exposure
While PFAS are widespread, you can take steps to limit your family’s exposure. Avoid non-stick cookware, choose stainless steel or cast iron instead. Filter your drinking water with a certified PFAS-removing filter. Reduce consumption of fast food and greasy takeout, as the wrappers often contain PFAS. Check product labels for “PFOA-free” or “PFAS-free” claims.
FAQ
What are forever chemicals?
Forever chemicals, or PFAS, are synthetic compounds that do not break down in the environment and are linked to serious health problems, including gut inflammation in children.
How do PFAS cause gut inflammation in children?
Prenatal or early childhood exposure to PFAS can disrupt the immune system and gut microbiome, leading to chronic intestinal inflammation that may progress to inflammatory bowel disease.
Can PFAS exposure be reversed?
PFAS accumulate in the body and are difficult to eliminate. However, reducing exposure through diet, water filtration, and avoiding PFAS-containing products can lower future health risks.
Protecting children from forever chemicals starts with awareness. By understanding the risks and taking proactive steps, parents can help reduce the likelihood of gut inflammation and other PFAS-related health issues. Stay informed and consult your pediatrician for personalized advice.
