"Chloride is found in table salt or sea salt as sodium chloride. It is also found in many vegetables. Foods with higher amounts of chloride include seaweed, rye, tomatoes, lettuce, celery, and olives. Chloride, together with potassium, is also found in most foods and is usually the main ingredient of salt substitutes. Most Americans probably get more chloride than needed, in the form of table salt and salt in prepared foods. Too little chloride in the body can occur when your body loses a lot of fluids. This may be due to excessive sweating, vomiting, or diarrhea. Medicines such as diuretics can also cause low chloride levels."
