represented by a broad spectrum of compounds as phytic acid, oxalic acid, solanine, inhibitors of
various enzymes and others. Consumed in excess the mentioned substances may significantly

Substanţele antinutritive şi toxice naturale sunt răspândite în diferite alimente. Acestea sunt
reprezentate printr-un spectru larg de compuşi ca acidul fitic, acidul oxalic, solanina, inhibatori
