Some of the lowest sodium soups are Healthy Choice's Chicken with Rice canned soup, which contains 390 milligrams of sodium. Amy's Low Fat Minestrone, which contains 290 milligrams of sodium, or Health Valley Organics Tomato Soup, which contains 35 milligrams of sodium, are also low-sodium choices.
Low-sodium foods have 5 percent or less of the recommended daily value for sodium, states WebMD. Foods with that have 20 percent or more of the recommended daily value are high-sodium foods. The daily value on product labels is based on 2,300 milligrams of sodium. Studies suggest that cutting back even more on sodium decreases the risk of hypertension.
