As long as you avoid salty foods, you’re fine.
Sodium isn’t evil. You need the nutrient to survive, and your body can’t produce it on its own. The electrolyte (yes, that’s what sodium is) contributes to blood volume, and, if you’re active, that’s a biggie. Maintaining normal blood volume helps your skin dissipate heat, helps you absorb nutrients and delivers oxygen to hardworking muscles, including your heart. Sodium is the mineral lost in the greatest quantities in sweat and urine, and replacing it is essential for proper hydration. So how much is too much? It’s complicated.
