Scientists tested 212 plant-based meat alternatives. Every one contained fungal toxins
Every one of 212 plant-based meat alternatives and drinks tested in the UK contained at least one naturally occurring fungal toxin, though concentrations remained below recommended EU guideline levels. Researchers say the bigger question is whether regularly eating large amounts of these foods could lead to potentially concerning cumulative exposure over time.
A comprehensive survey of plant-based products available in the United Kingdom has revealed that mycotoxins, toxic substances produced by fungi, are present in every one of the 212 plant-based meat alternatives and beverages examined. Mycotoxins were detected in all 19 varieties of these foods, with some products containing multiple types.
The investigation, conducted by the University of Parma in Italy and Cranfield University, analyzed a variety of popular plant-based items including burgers, vegetarian chicken pieces, vegan sausages, and plant-based milks such as oat, almond, and soy. Mycotoxins are particularly prevalent in plant-based foods due to the susceptibility of grains, legumes, and seeds to mold during growth and storage.
Despite the presence of these toxins, the concentrations found in UK products were found to be below the established EU guidelines. Experts from Cranfield University emphasized that while the levels are not likely to cause immediate harm from a single product, repeated exposure to small amounts could potentially lead to health issues over time.
The main concern is the potential for cumulative exposure if a person consumes a primarily plant-based diet without proper management. While individual plant-based products are unlikely to pose a problem, a diet consisting mainly of plant foods could increase overall exposure. The research provides valuable data to estimate dietary exposure and inform risk assessments for consumers.
Researchers are working with the food industry to establish effective mycotoxin management standards, especially for new plant-based products.
