A Boston University study found that consuming beta-glucan fiber supplements reduced levels of PFAS, or 'forever chemicals,' in men's blood by eight percent over four weeks. PFAS, found in many household items, are linked to cancer and other health problems. Participants consuming the fiber supplement before meals showed a decrease in PFOA and PFOS, two particularly harmful PFAS. While promising, the study's four-week duration is a limitation, and further research is needed. The findings highlight the potential of fiber to mitigate PFAS exposure, particularly given that most Americans don't consume enough fiber.
