The phrase "vegetables and grains" refers to a group of foods that are derived from plants. Vegetables are edible parts of a plant, such as leaves, stems, and roots, while grains are the seeds of grasses that are used for human consumption. Both vegetables and grains provide important nutrients, including vitamins, minerals, fiber, and antioxidants, which are essential for maintaining good health. Including a variety of vegetables and grains in one's diet can help to ensure that they are getting all the necessary nutrients their body needs.
