Some salt-free foods include fruits and vegetables, which contain very little salt when compared to their other components. Other salt-free foods are many types of grains, legumes and foods such as olives and raw nuts.
Fruits are a highly nutritious addition to a salt-free diet because they feature numerous nutritional supplements, such as vitamins A and C and fiber. A 1-cup serving of most fruits only contains roughly 2 to 4 milligrams of sodium.
Most vegetables also contain very little sodium, though canned vegetables may contain salt to improve their preservation. Raw vegetables such as green bell peppers, broccoli, onions and radishes only contain up to 4 milligrams of salt. Watch out for sodium-free canned vegetables if you are planning a recipe that involves such products.
Beans and grains also do not contain sodium, but there are some canned varieties that may have salt for preservation reasons. Soaking dried beans is one way to get the necessary fibers and nutrients from the foods without risking exposure to sodium. Pasta, lentils, rice and oat bran products also contain very little sodium, though some products may feature more sodium based on their composition. Additionally, many spices, such as garlic powder, cumin, nutmeg, cinnamon and black pepper, contain no salt unless they are specifically mixed with salt.
