Several new health studies have been released addressing public concerns about various substances and medical conditions, providing updated scientific evidence on their safety and risks.

A long-term study tracking over 10,000 people for multiple decades found no negative effects of fluoride on brain function, according to research reported by NBC News. The study represents one of the most comprehensive examinations of fluoride's neurological impact to date.

Separately, the Centers for Disease Control and Prevention reported that kratom-related poisonings have increased by approximately 1,200% over the past decade, with a notable surge in 2025. However, experts suggest the increase may be attributed to synthetic derivatives like 7-OH rather than natural kratom. Walter Prozialeck, a pharmacology professor at Midwestern University, indicated he was not surprised by the findings and noted that natural kratom may offer benefits for pain management and addiction recovery.

A comprehensive study from Denmark published Monday found no link between acetaminophen use during pregnancy and later autism diagnoses in children. The research addresses previous unfounded claims that Tylenol use during pregnancy significantly increases autism risk, claims that have reportedly led to decreased use of the pain reliever among pregnant individuals.

Additionally, research published in BMJ Journals has identified a connection between newly developed anemia and increased cancer risk. The study found that patients with new-onset anemia face significantly higher chances of cancer diagnosis and all-cause mortality within 18 months of the blood condition's development.
