"Rice-based" refers to products or dishes that primarily use rice as a main ingredient. This can include a variety of foods, such as rice cakes, rice noodles, and rice pudding. Rice is a staple food in many cultures around the world, providing a source of carbohydrates and energy. In addition to traditional dishes, "rice-based" can also describe products like rice flour or rice milk, which are alternatives to wheat flour and dairy milk, respectively. These alternatives are often used in gluten-free or lactose-free diets, making them popular among those with dietary restrictions.
