Nutritional enhancement refers to the process of improving the nutritional quality of food products. This can be achieved through various methods, such as fortification, where essential vitamins and minerals are added to foods, or biofortification, which involves breeding crops to increase their nutrient content. The goal is to address nutrient deficiencies in populations and promote better health. Another approach to nutritional enhancement is through the use of functional foods, which are foods that provide health benefits beyond basic nutrition. These may include ingredients like probiotics for gut health or omega-3 fatty acids for heart health. By incorporating these elements, individuals can improve their overall diet and well-being.
