Micronutrients & recovery
Industrial dry milling and nixtamalization processing of maize significantly alters its micronutrient profile, typically reducing vitamins and fiber while increasing calcium, thereby necessitating targeted fortification to prevent micronutrient malnutrition.
If you rely on maize as a staple, be aware that processing (milling, cooking) changes its nutritional value. Industrial processing often removes beneficial fibers and vitamins. To maintain health, ensure your maize products are fortified with essential vitamins and minerals, or consume a diverse diet to compensate for processing losses.
Various industrial processes... entail changes in nutrient composition... Vitamin and mineral losses during processing are identified and the nutritional impacts outlined.
