Salty foods can be good for you, in moderate amounts. Salt helps prevent dehydration by keeping fluids in your body. When you're sweating, it's particularly helpful to eat some salt to guard against fluid loss. Stay away from preserved meats – they are hard to digest and toxic to your liver. Do incorporate foods like chicken stock, miso soup, and nuts into your regular diet. In some cases, salt may aggravate high blood pressure. If you have high blood pressure, check with your medical practitioner before adding salty foods to your diet.
