Is your brain health at risk from foil food boxes and your wet raincoat? Here's all you need to know about forever chemicals
Is the food that you have from the cardboard/foil box delivered by a food app or the raincoat that's shielding you from the rain affecting your brain health? Many of us may not know this but our everyday items may be leaching compounds into our gut and skin that's insidiously triggering persistent health problems.
This is because most consumer goods contain PFAs (per- and polyfluoroalkyl substances), a group of chemicals that have a powerful ability to repel oil and water and resist heat. For long these have been widely used in various products like non-stick cookware, firefighting foam, water-resistant clothing and food packaging, making them pervasive in everyday life. 'These do not get destroyed in the environment or the human body and tend to persist, earning the moniker forever chemicals. However, because of their persistence, they can cause significant health concerns. Many people are exposed to forever chemicals through drinking water, food and even dust,' says Dr Praveen Gupta, Chairman- Neurosciences, Marengo Asia Hospitals, Gurugram.
The worst part, he says, is that they might be stuck in your body for years. A new study by the researchers from the Del Monte Institute for Neuroscience at the University of Rochester recently found that early life exposure to forever chemicals may increase anxiety-related behaviors and memory deficits in male mice.
How do forever chemicals impact your health?
They can interfere with the endocrine system, which regulates hormones, potentially affecting reproductive health and development. Studies have shown associations between exposure to forever chemicals and liver damage and thyroid dysfunction. PFAS can weaken the immune system, potentially reducing the body's ability to fight infections and respond to vaccines. Certain PFAs have been linked to an increased risk of kidney and testicular cancers, according to the National Cancer Institute. But now they are being studied for their impact on brain health?
How neurotoxic are forever chemicals?
This is a relevant concern now because of their ability to penetrate the blood brain barrier. This acts as a protective filter, regulating the movement of substances between the bloodstream and the brain, allowing essential nutrients in while keeping harmful substances out. But now the latest mice study has shown that they are permeating this barrier. This is significant because the damaging effects continued long after the exposure.
Once the barrier is breached, these chemicals disrupt key neurotransmitters (chemical messengers that transmit signals across the nervous system) particularly dopamine, which impacts movement, motivation, mood and reward, as well as glutamate, which stimulates nerve cells so that they can pass on signals to each other. It's essential for normal brain function, including learning and memory.
Forever chemicals may also destroy nerve cells by interfering with genes. They can also stimulate neuroinflammation and damage brain cells. That's why we have impaired sleep. All of this leads to neurodegenerative processes and impacts cognition and increases the risk of Alzheimer's. They can also be related to behavioural disorders in children like ADHD or lower academic performance.

Tool that can remove cancer-causing forever chemicals from water in minutes, developed by scientists
A team of researchers has developed a groundbreaking tool that can remove more than 99% of cancer-causing 'forever chemicals' from drinking water in just five minutes. The high-tech device, created by scientists at the University of Utah , not only purifies water with remarkable efficiency but also glows when it detects contamination, making it a real-time monitoring system as well. Known as PFAS, these persistent chemicals are linked to cancer and other serious health problems. This new invention could transform how we tackle toxic water pollution across the globe. The cancer connection: why forever chemicals are a serious health risk Forever chemicals, officially known as per- and poly-fluoroalkyl substances (PFAS), are synthetic compounds used in a wide range of consumer products, from non-stick cookware to waterproof fabrics. Because they do not break down easily in the environment, they accumulate in soil, water, and even the human body. Studies have linked them to several health risks, including cancer, liver damage, immune system dysfunction, and developmental delays in children. How the new filtering technology works and what it targets The research team developed a lab-made crystalline material called a metal-organic framework (MOF), which acts like a molecular sieve. As contaminated water passes through the MOF, it captures and traps PFOA, one of the most toxic types of PFAS, removing more than 99% of it within minutes. This process is not only rapid and effective but also proven to function in complex environmental conditions, including the presence of salts and natural organic matter. A glowing warning system built into the material What sets this tool apart is its built-in detection feature. When PFAS molecules bind to the MOF material, it emits a fluorescent glow, allowing users to instantly confirm whether water is contaminated. This dual capability of purification and detection makes the tool especially valuable for both water treatment and real-time environmental monitoring. A reusable and sustainable solution Unlike many existing PFAS removal technologies that are costly and degrade with repeated use, the new MOF filter is reusable. In tests, the material maintained 93% of its efficiency even after five wash cycles, pointing to its potential as a low-cost, long-term solution for filtering drinking water. What this means for public health and next steps With over 200 million Americans estimated to have PFAS-contaminated water, this new development is a promising step toward safer drinking supplies. Although the MOF-based system is still in the research phase, scientists believe it could eventually be adapted for everyday use. Until then, people living in areas with known PFAS contamination are encouraged to use water filters certified by the National Sanitation Foundation to reduce exposure to PFOA and PFOS.

Can gut microbes help flush out forever chemicals in your body? Here is what experts have to say
Could your gut help clear out toxic 'forever chemicals'? Scientists are beginning to explore the possibility that certain gut bacteria might help remove per- and polyfluoroalkyl substances (PFAS) - colloquially known as forever chemicals - a class of chemicals linked to cancer and other health harms from the body. A study published in Nature Microbiology found that certain gut bacteria were able to absorb PFAS, allowing mice with these microbes in their gut to excrete the chemicals through faeces. The findings add to growing interest in how gut microbes could influence the body's handling of environmental pollutants. What are PFAS and how do they accumulate in the body? PFAS are a large class of synthetic chemicals often called 'forever chemicals' due to their strong carbon-fluorine bonds, which make them highly resistant to degradation in the body or environment. 'These chemicals have been used since the 1940s across everyday products, from nonstick cookware and food packaging to firefighting foams,' said Uday Nagesh Shivangi, senior consultant and clinical lead in medical gastroenterology at Narayana Health, Bengaluru. These chemicals primarily enter the body through ingestion of tainted water or contaminated food like fish, meat, or eggs. Inhalation of contaminated dust and skin contact with PFAS containing items are also possible, though less prominent. Once inside, PFAS bind to serum proteins like albumin and accumulate in organs like the liver and kidneys, as well as in the bile staying in the body for years, explained C. Kolandasamy, senior consultant, department of surgical gastroenterology, Rela Hospital, Chennai. The process of enterohepatic circulation in which substances excreted in bile re-enter the intestines and are reabsorbed into the bloodstream can further prolong their half-life in the body. . 'Some of these chemicals, like PFOS or PFOA, can remain with half-lives of over 8 years,' Dr. Shivangi explained. Can gut bacteria help eliminate PFAS? In the recent study , researchers observed that mice carrying specific types of gut bacteria were able to excrete PFAS more effectively through faeces, compared to germ-free mice. 'This research gives us early clues about how the gut microbiome might influence PFAS elimination,' Dr. Kolandasamy said. 'Certain bacteria appear to bind to PFAS molecules, preventing their absorption and helping excrete them via faeces.' The mechanism is not one of chemical breakdown, but rather of sequestration, where microbes like Lactobacillus or Bacteroides bind to PFAS in the gut and trap them for elimination. Some microbial metabolites, such as bile acid conjugates, may also play a role in promoting excretion. 'Not all microbes do this,' cautioned Kayalavizhi Jayaraman, consultant gastroenterologist, Prashanth Hospitals, Chennai, 'Animal studies have shown that strains like Bacteroides can accumulate PFAS within them. While it's tempting to think of these microbes as filters, much more research is needed before recommending them for PFAS clearance.' The idea is scientifically compelling but still at a preclinical stage. 'So far, the most convincing data comes from lab and animal studies,' said Dr. Kolandasamy. 'Mice with a diverse microbiome show reduced PFAS absorption compared to germ-free mice. However, no human clinical trials have conclusively demonstrated that boosting specific gut bacteria reduces PFAS levels.' Dr. Jayaraman added that human evidence is mostly observational at this point. 'We do see associations between PFAS exposure and gut dysbiosis -- meaning changes in microbial diversity, but studies on actively changing the human microbiome to eliminate PFAS are still lacking.' Role of diet and gut health While there is no specific diet proven to eliminate PFAS, certain dietary strategies could support the gut's natural filtering functions. 'Dietary fibre has shown potential,' said Dr. Kolandasamy. 'Fiber can bind to bile acids, which also carry PFAS, promoting their excretion. Similarly, probiotics, particularly those containing Lactobacillus strains have shown reduced PFAS absorption in rodent models.' Pilot studies have also explored the use of bile acid sequestrants such as the cholesterol-lowering drug cholestyramine to lower serum PFAS levels. 'These findings suggest gut-focused therapies could be promising in the future,' he added. Dr. Jayaraman emphasised a preventive approach. 'While we don't yet have a diet protocol to clear PFAS, eating wholesome foods, increasing fibre, and limiting processed and packaged food items may support overall gut health and resilience. It is also wise to avoid non-stick cookware and limit known PFAS exposures.' Future research With growing awareness of chemical exposures in everyday life, researchers are exploring whether microbiome-based therapies such as designer probiotics or even faecal microbiota transplantation (FMT) could one day help detoxify environmental chemicals like PFAS. 'There is already interest in engineering bacteria that express PFAS-binding proteins,' said Dr. Kolandasamy. 'But these are still early-stage concepts, and there are regulatory and scientific challenges to overcome.' Dr. Jayaraman added 'While it's exciting to imagine a future where a probiotic capsule could help clear toxins, we need years, if not decades of research, to reach that point. Until then, the focus should remain on minimising exposure and supporting gut health naturally.' This is a field worth watching,' said Dr. Kolandasamy, 'but for now, prevention and awareness remain the best defense.'
