Fast Food, Instant Meals, and Packaged Foods
Fast food, instant meals, and packaged foods usually contain high levels of sodium. This is why doctors always advise people with kidney disease [5] to stay away from them. Examples of these foods include frozen pizza, frozen boxed meals, instant noodles, and other types of microwavable foods. For example 102 grams of frozen pepperoni pizza contains 568 mg of sodium. This is one-quarter of the recommended sodium intake if you have kidney disease. These foods are usually heavily processed and contain high levels of refined carbs. If you have kidney disease, it is advisable to avoid meals that contain refined carbs.
