12. Potatoes & Sweet Potatoes
Even though sweet potatoes and potatoes aren’t unhealthy vegetables, they can be unhealthy for a patient with kidney damage because of their incredibly rich concentration of potassium. Consuming one medium-sized baked potato will provide your body an alarming 610 mg of potassium, while a small-sized baked sweet potato packs up a whopping 541 mg of potassium.
If you must devour potatoes and sweet potatoes, it is important to first reduce their potassium concentration. Luckily, we can reduce the potassium density of various potassium-packed veggies and fruits, including sweet potatoes and potatoes, by simply soaking or leaching them. If you chop down the potatoes or sweet potatoes into tiny cube-like pieces and allow them to boil for at least 10-15 minutes, it will help cut down the potassium concentration by a striking 50%.
Another impressive method of reducing the potassium content is soaking up the potatoes in a large pot of water for more than four hours before you bake or cook them. It brings about a striking reduction in the potassium content as compared to potatoes that are not soaked prior to cooking. This technique is referred to as potassium leaching, and it is more popularly known as the double cook method.
Just be sure to keep in mind that while the method of potassium leaching helps in reducing the potassium content in potatoes, this technique does not eliminate the potassium entirely. Even double-cooked potatoes and boiled sweet potatoes pack up significant amounts of potassium content. Therefore, it is highly advisable to consume mindfully moderate portions so your potassium levels remain under control.
Despite packing a beneficial concentration of several essential nutrients, tomatoes are another fruit that are loaded with a dangerously high concentration of potassium, which is why they are not a favorable ingredient for an effective renal diet. Tomatoes are commonly added to sauces and meals, and they are also served raw in salads or sandwiches, along with being stewed in soups.
Beware of your consumption of tomatoes because only one cup of tomato sauce can pack up more than 900 mg of potassium. It can be challenging for anyone on a renal diet to avoid the consumption of tomatoes because these ripe red fruits are most commonly added to a large variety of dishes and recipes.
Depending on your unique taste palette and eating preferences, you can find a delicious alternative for tomatoes that contains a much lesser concentration of potassium. You can easily alternate tomatoes with roasted red pepper to create a savory red sauce that will provide you various nutrients and a considerably lesser density of potassium.
14. Packaged, Instant and Pre-Made Meals
Processed foods, ready to make meals and all packaged varieties are a major source of excessive quantities of sodium in our daily diet. These packaged and pre-made meals pack up excessive amounts of salt with no traces of nutrients, and it is best to eliminate them from a renal diet.
Majority of the varieties of packaged and instant ready meals usually contain heavily processed ingredients, and therefore, they are packed with sodium. Some popularly consumed varieties include microwaveable meals, frozen pizzas, and instant noodle packages. If you are consuming heavily processed foods and pre-made meals on a daily basis, it can be extremely challenging for you maintain a 2000 mg per day limit for your sodium consumption. Aside from packing up heaps of sodium, these processed foods are loaded with unhealthy fats and lack essential nutrients that the body requires.
