Strengthening, or fortification, refers to the process of enhancing the nutritional quality of food by adding essential vitamins and minerals. This practice aims to prevent deficiencies in populations that may lack access to a balanced diet. Commonly fortified foods include salt with iodine, flour with iron, and milk with vitamin D. Fortification can be an effective public health strategy, especially in areas where specific nutrient deficiencies are prevalent. By improving the nutritional content of staple foods, fortification helps support overall health and well-being, reducing the risk of related diseases and promoting better growth and development in children.
