PFAS, or "forever chemicals," are widespread in the environment and can accumulate in our bodies. These synthetic chemicals infiltrate our food, water, household products, and even our bodies. They resist breakdown and persist in the environment and the human body, earning the label "forever chemicals". Specific strains of human gut bacteria can effectively absorb these "forever chemicals", trapping them within their cells. The full impact of PFAS on health remains unclear, but studies have connected these chemicals to cancer, heart disease, reduced fertility, and other adverse effects.
While no method has been found to destroy PFAS, recent discoveries suggest potential strategies for removing these harmful "forever chemicals" from our bodies, where they cause the most damage. Scientists are investigating targeted probiotic supplements to increase PFAS-absorbing bacteria in the gut, aiming to strengthen the body’s natural capacity to eliminate these toxic chemicals before they build up to harmful levels.Â
The study has identified nine bacterial species capable of capturing up to 75% of these toxic compounds. When introduced into mice, within minutes these bacteria quickly absorbed PFAS chemicals. As the bacteria were expelled through the gut, they carried the forever chemicals out with them in waste. The study showed they consistently removed a stable proportion of the toxins, indicating their potential as a natural gut filter.
Scientists aim to create probiotic supplements to enhance these beneficial bacteria, providing a novel approach to lowering PFAS levels in humans. However, although encouraging, these findings have not yet been directly tested in human subjects. The next phase involves conducting human clinical trials to determine if probiotics can boost the levels of PFAS-absorbing bacteria in the gut and to evaluate the safety of these interventions.

The risk of dementia may be influenced long before symptoms appear. New research suggests that avoiding three key midlife risks could help extend the number of years people live without dementia. Those free of all three risk factors experienced roughly 13 additional dementia-free years compared with people affected by all three.
While it’s well known that processed foods can harm health, a new study reveals the problem runs deeper than just excess calories, refined carbs, or unhealthy fats. Researchers found that certain preservative additives are independently associated with increased risk of high blood pressure and cardiovascular disease.
A slower walking pace is a common part of aging, but the reason may be more complex than previously thought. New findings suggest that older adults unconsciously prioritize staying upright and stable, even if it requires more effort and energy. Â Although this shift may help maintain balance, researchers found that it can also lead to slower walking speeds, greater fatigue, and a heightened susceptibility to falls.
