antinutritiva
Antinutritional factors, or antinutrients, are substances found in foods that reduce the availability or absorption of nutrients. They occur in many plants and, to a lesser extent, in animal products, and are often concentrated in seeds, grains, legumes, and leaves. In nutrition science, antinutrients may affect mineral uptake, protein digestion, or metabolic processes, and can influence thyroid function or gut health when consumed in high amounts. They are not inherently harmful at normal dietary levels, and some may have beneficial biological activities.
Common mechanisms include chelation and complex formation, enzyme inhibition, and interference with transport. Phytates bind minerals
Typical sources are cereals and grains, legumes, nuts and seeds, and certain leafy vegetables. Processing steps
The overall impact depends on the amount ingested, the rest of the diet, and how the foods
