A major study found higher fiber intake may reduce PFAS levels in the body
May, 2025 - A recent study published in The Guardian reports that people who consume more dietary fiber may excrete greater amounts of PFAS, particularly the harmful compounds PFOA and PFOS.

Researchers suggest that fiber may bind to these persistent chemicals in the digestive system, helping the body eliminate them more effectively. These findings add to growing evidence that everyday nutrition choices can impact long-term exposure to environmental toxins.
The study tracked participants' diets and PFAS levels over time and found consistent associations between fiber intake and chemical excretion. While more research is needed to isolate which fiber types are most effective, the takeaway is clear—higher fiber consumption may help reduce the body’s toxic load.
This studies findings:
-
Higher fiber intake was linked to greater PFAS excretion.
-
Each additional 5g of fiber lowered PFOS levels by 11.7%.
-
PFOA levels dropped by 5.6% per 5g fiber increase.
-
PFAS reduction was consistent across age, sex, and diet variables.
-
Over 600 people were included in the study.
-
Data came from two national U.S. health surveys.
-
No specific fiber type was identified as most effective.
-
Fiber intake showed stronger effects than other dietary factors.
-
The study focused on blood concentrations of PFOS and PFOA.
-
Researchers concluded diet could support PFAS elimination.
With PFAS contamination becoming a national concern, the role of diet as a proactive tool is gaining traction fast.
Hona Fiber + Greens delivers detox-supporting fiber alongside gut-friendly nutrients
Hona’s Fiber + Greens offers 7 grams of dietary fiber from psyllium husk and chicory root, both of which are known for their digestive and detoxification properties.
These ingredients support regular elimination and may aid the body in clearing waste, including chemical byproducts. The blend also includes prebiotics, probiotics, and greens like chlorella—an algae studied for its potential to bind toxins.
Taken daily, Hona’s supplement helps close the fiber gap while giving users a clean, energizing formula that fits into busy routines. With both soluble and insoluble fiber sources, the blend supports digestion, gut flora, and potentially the body’s ability to excrete harmful substances more efficiently. It’s a straightforward way to increase fiber without guesswork.
Public concern about PFAS is growing as chemicals are detected in water, food, and blood samples
PFAS exposure is now part of daily life. These synthetic chemicals have been found in municipal drinking water, fast food packaging, produce, and even the blood of nearly every person tested in a recent CDC review.
They're persistent, meaning they stay in the environment—and in the body—for years. Health agencies have linked long-term PFAS exposure to cancer, thyroid disease, reproductive problems, and immune suppression.
While federal regulations are beginning to respond, many people are looking for ways to reduce their personal exposure now. That’s where dietary strategies like fiber intake are gaining traction. Fiber moves waste through the digestive tract and may help carry PFAS compounds with it. It’s one of the few proactive habits that’s both low-effort and backed by established digestive science.
Hona encourages consumers to take daily fiber seriously as part of long-term wellness
Most Americans don’t get enough fiber—and that gap could affect more than digestion. With new research connecting fiber to lower PFAS levels, the conversation is expanding. Hona sees an opportunity to help people take action using ingredients that are familiar, functional, and consistent.
Each serving of Hona’s Fiber + Greens delivers a precise blend of psyllium husk and chicory root, offering both soluble and insoluble fiber. That means support for gut health, regularity, and potentially greater waste elimination. The formula is rounded out with probiotics and nutrient-rich greens like chlorella and spirulina, which many users already take for gentle detox support.
Daily fiber isn’t a flashy fix—but it works. That’s the message Hona is focused on sharing.
In a landscape full of synthetic supplements and temporary trends, the company continues to highlight ingredients that actually support how the body clears waste. Including the kind of waste no one expected to be dealing with.
