Canned soup is another spot where you’ll find heaps of sodium—we’re talking 800 mg per cup, says White.
Stock this instead: Low-sodium canned soups, or sodium-free chicken stock
The magic number for soup is 350 mg of sodium. Anything above that may have a negative impact on blood pressure. That goes for even the healthiest-sounding flavors, like vegetable or barley. An even better idea: Break out the blender and make your own soup. Combine sodium-free chicken broth, Roma tomatoes, broccoli, avocado, and onions for a super-easy lunch or dinner.
