Fruits and vegetables are a major source of exposure to microplastics and PFAS, and the consumption of beta-glucans could help promote the excretion of these substances.

Research does indeed confirm the presence of microplastics in fresh produce, absorbed by roots via contaminated soil or water, as highlighted in recent studies (e.g., Environmental Research). Regarding PFAS, their persistence in the environment makes their presence in the food chain inevitable, which validates the idea that simple washing is insufficient. The claim about beta-glucans (soluble fibers found in oats or mushrooms) is based on preclinical or mechanistic studies suggesting an interaction with the microbiota or binding to pollutants, but direct clinical evidence in humans for the specific excretion of PFAS remains very limited and preliminary. It is important to note that the nutritional benefit of fruits and vegetables currently far outweighs the risks associated with these pollutants. The approach is therefore cautious: the environmental assessment is solid, but the use of supplements as a solution remains a hypothesis that requires further scientific validation.
