Step-by-step explanation:
When foods have been enhanced with extra vitamins or minerals, they have been fortified. This is a common process used to improve the nutritional quality of food and help individuals meet their daily nutrient requirements.
Examples of fortified foods include calcium-fortified orange juice, breads enriched with B vitamins, and cereals fortified with various vitamins and minerals. It's crucial to note, however, that while some health claims of modified foods are supported by research, others may be less clear or unsupported, and checking with a health professional is always recommended.
