Final answer:
During food processing, the removal of various nutrients can occur, such as bran and germ, fiber and protein, and vitamins and minerals. However, some nutrients may be added back through fortification or enrichment.
Step-by-step explanation:
During food processing, several nutrients can be removed, leading to a decrease in their content in the final product. One example is the removal of bran and germ, which are rich in fiber, vitamins, and minerals, during the refinement of grains. Additionally, processing can result in the loss of vitamins and minerals, as well as the removal of fiber and protein. However, it is important to note that in some cases, nutrients may be added back through fortification or enrichment.
