Sodium is an important electrolyte mineral, but not when it is consumed in high amounts. A hot dog contains nearly 700 mg of sodium. Reducing the amount of sodium you consume can help lower high blood pressure or prevent it from developing in the first place, according to the American Heart Association. The recommended daily intake of sodium is 2,300 mg.
