Flavonols found in foods can block drug resistance protein and boost medication absorption

Researchers identified specific flavonols that potently inhibit breast cancer resistance protein (BCRP), a key driver of drug resistance and poor oral drug absorption. The study found that these flavonols can reverse chemotherapy resistance in vitro and boost drug exposure in animal models, though clinical translation remains uncertain.

Prenatal phthalates lower boys' verbal IQ but lift girls' performance IQ, Canadian study reveals

Prenatal exposure to certain phthalates, especially DiDP, was linked to slightly lower IQ scores in preschoolers, with boys appearing more vulnerable. Other phthalates, like MMP and MBzP, showed small positive associations, but mixture effects were not significant.

Forever chemicals cross placenta and breast milk affecting babies’ immunity

New research reveals that tiny amounts of PFAS-widely known as "forever chemicals"-cross the placenta and breast milk to alter infants' developing immune systems, potentially leaving lasting imprints on their ability to fight disease.

Ultra-processed foods threaten brain health in kids and teens, review warns

Children, adolescents, and unborn babies exposed to high levels of ultra-processed foods (UPFs) face increased risks of impaired brain development, cognitive deficits, and long-term mental health challenges. The review underscores how UPF-driven changes in reward pathways, nutrient deficits, inflammation, and the gut–brain axis can have lasting impacts across generations.
