Good Chance with Potatoes & Sweet Potatoes
Potatoes and sweet potatoes are known for their high levels of potassium as a regular-sized baked potato can have up to 610 mg of potassium while a sweet potato would have around 541 mg. However, there may be a glimmer of hope with both types of potatoes as they can be soaked or leached to reduce the potassium they contain. You can dice the potatoes and boil them for roughly 10 minutes to reduce up to 50% of the potassium, while soaking for at least four to five hours may reduce the levels even lower. After all, you may be able to enjoy that potato pie but, of course, in moderation.
Eating Tomatoes
Tomatoes have a high potassium rate whether raw or cooked, and a tomato sauce can have up to 900 mg of potassium. You may opt for an alternative like a roasted red pepper sauce, which brings about a similar flavor and taste but is much healthier for your kidneys. Fans of Italian cuisine that cannot go a day without a saucy pizza or a rich spaghetti Bolognese will sadly need to start varying their diets.
