11. Onions: A Flavorful, Low-Potassium Vegetable
Onions are a versatile vegetable that can add flavor and variety to a kidney failure diet plan. They are a low-potassium food, making them a good choice for individuals with kidney disease who must limit their potassium intake. Potassium is a mineral that is important for many bodily functions, but in individuals with kidney disease, it can build up to dangerous levels in the blood.
In addition to being low in potassium, onions are also low in phosphorus, another mineral that people with kidney disease must limit. Phosphorus is found in many foods and can also build up in the blood of individuals with kidney disease. Limiting phosphorus in the diet can help to reduce the risk of developing further kidney damage.
Onions can be used in a variety of ways in cooking, including raw in salads, grilled, roasted, sautéed, or caramelized. They can also be used to add flavor to soups, stews, and sauces. One of the great things about onions is that they are available all year round, so you can enjoy their flavor and benefits regardless of the season.
When purchasing onions, look for firm bulbs that are free from soft spots, mold, or other signs of decay. Onions can be stored in a cool, dark place for up to two months. To chop an onion, start by cutting off the top and bottom of the onion, then peel away the skin. Cut the onion in half from top to bottom and remove the root end. Make several cuts down the length of the onion, then make several cuts across the width of the onion to create small, evenly-sized pieces.
It is important to keep in mind that while onions are low in potassium, they are still a relatively high-sodium food. Individuals with kidney disease must also limit their sodium intake to help manage high blood pressure and protect the kidneys. Be sure to include a variety of other low-potassium, low-sodium foods in your diet to help meet your nutritional needs and reduce your risk of developing further kidney damage.
Incorporate onions into your diet by adding them to soups, stews, stir-fries, or salads. Cook onions in olive oil for a kidney-friendly option that is both flavorful and nutritious. (11)
