Summary
This 2020 narrative review by Petroski and Minich, published in the MDPI journal Nutrients, critically evaluates the scientific evidence surrounding plant-derived compounds commonly labelled as 'anti-nutrients', including lectins, phytates, oxalates, and tannins. The authors assess whether these compounds pose meaningful health risks at levels typically found in a balanced diet, and consider the broader context of food preparation, gut microbiota, and individual variation. The review likely concludes that, for most healthy individuals consuming a varied diet, the purported harms of anti-nutrients are overstated relative to the well-evidenced benefits of plant food consumption.
UK applicability
Although not UK-specific, the findings are broadly applicable to UK dietary guidance and public health messaging, particularly in the context of government encouragement of plant-rich diets and ongoing consumer interest in elimination of supposedly harmful food components.
Key measures
Biological activity of anti-nutrient compounds; evidence thresholds for adverse effects; dietary exposure levels; nutrient bioavailability impacts
Outcomes reported
The review examined the evidence for and against the harmful effects of so-called anti-nutrients (such as lectins, phytates, oxalates, tannins, and glucosinolates) in plant-based foods, assessing their biological activity, dietary relevance, and potential health implications at typical consumption levels.
