  • Choosing the Right Water Pitcher Filter: Expert Insights
    Dr. Fitzgerald emphasizes understanding water contaminants before choosing a filter. She highlights the Epic Pure Pitcher for its "98% PFAS reduction." While pitcher filters are convenient, they may not remove all toxins. For comprehensive filtration, consider systems like reverse osmosis or ion exchange. Check NSF's database for certified options.
  • Fiber Intake May Reduce PFAS "Forever Chemicals" in Bloodstream
    Dr. Fitzgerald suggests that "an increase in dietary fiber would be worth incorporating" to reduce PFAS body burden. PFAS, persistent "forever chemicals," are linked to health issues and found in water, food, and air. Consumers should seek "PFAS-free" products and consider reverse osmosis for water purification.
  • Prenatal Acetaminophen Use Linked to Increased ADHD Risk in Children
    Dr. Fitzgerald highlights a study linking maternal acetaminophen use to higher ADHD rates in children, especially girls. With 41-70% of pregnant women using acetaminophen, she urges reevaluation of its long-term risks. Shannon emphasizes the need for further investigation and suggests lifestyle measures as first-line treatment during pregnancy.
