Breakfast is the most important meal of the day. How often have we heard this and how often have we educated our patients on the importance of breakfast? Ready-to-eat cereals are popular, quick, and easy breakfast foods for patients of all ages. It is our job to help patients choose a cereal that fits well into their renal diet while helping them wade through claims regarding fiber, whole grains, vitamins, and minerals. With respect to cereals geared toward children, there may be concerns that some of them are high sugar containing, presweetened foods.
