Grains have very little potassium except in the bran. Adding rice bran, corn bran or wheat bran to foods can increase the potassium content. Most of my clients find they need to use potassium broths or drinks to get the suggested amounts. They are not used to consuming the quantity of food necessary to get 4,000-6,000mg. of potassium a day. One potassium trick is to use tomato sauce, juice, paste or salsa.
Tomatoes are very high in potassium.
They can contribute significantly to your daily potassium intake. Tomato based sauce can help balance the lack of potassium in pasta. Using beans, in chili, soup or salad, increases the potassium, protein and complex carbohydrate content - and beans add color, flavor and texture. On a high potassium food plan the food is plain, no high calorie sauces. It is cooked by steaming or broiling or microwave.
