10 High-Sodium Foods to Avoid (2024)

Salt is everywhere — in foods where you would expect it to be, as well as plenty where you might not.

Americans love sodium chloride, also known as common table salt — and they eat far too much of it. Unfortunately for savory food fans, a diet high in sodium can wreak havoc on your health. According to the Harvard T.H. Chan School of Public Health, excess sodium increases your blood volume and with it, your blood pressure. Chronic high blood pressure can increase your risk of serious conditions like heart disease and stroke.

We do need sodium, though, for important bodily functions like maintaining good fluid balance, transmitting nerve impulses, and moving our muscles. So how much sodium can you safely eat each day? The latest dietary guidelines from the Food and Drug Administration (FDA) recommend keeping sodium levels below 2,300 milligrams (mg), or just 1 teaspoon (tsp), per day. A limit of 1,500 mg could benefit you even more, but if either of those aren’t possible for you at the moment, even cutting back by 1,000 mg could improve your blood pressure.

While most people already know it’s best to steer clear of saltyfoods like movie-theater popcorn and french fries, you also need to be on the lookout for less obvious foods that are loaded with sodium. From canned veggies to bread, here are secret salt mines to beware of.

Deli Meats Are Doused in Sodium

“Most people know better than to shake table salt all over their food, but there are plenty of hidden sources of sodium in our diets,” says Lanah J. Brennan, RDN, a registered dietitian based in Lafayette, Louisiana. “Sliced deli meats and hot dogs are packed with sodium.” One hot dog can contain as much as 700 mg of sodium, while just two slices of regular deli ham can have close to 250 mg. “Choose fresh meats or fish instead, and try making an extra serving at dinner and using the rest to make your lunch the next day,” she advises.

Do check the nutrition labels of raw meats, though; sometimes they can be “plumped” with a sodium solution to help retain moisture that nonetheless can quintuple their salt content.

Vegetable Juice Can Be a Liquid Salt Mine

Even a healthy-sounding option like vegetable juice can be high in salt. That’s why it’s important to read labels closely. Sodium content is listed per serving size; to be considered a low-sodium serving, it should be 140 mg or less, per the National Academy of Sciences. Even a can of tomato juice can be a mini sodium bomb, with more than 900 mg per 11.5-ounce (oz) serving. Your best bet is to squeeze your own fresh vegetable juice — a medium tomato has only 6 mg of sodium, per the U.S. Department of Agriculture.

Canned Soups and Vegetables Contain Untold Salt — and Are Still Bland

Anything in a can — from soup to tomatoes — could harbor high sodium shenanigans. “Check all those can labels, and choose products with less sodium per serving,” says Brennan. A classic 10.5-oz can of Campbell’s chicken noodle soup contains 2,225 mg of sodium, for instance — basically your entire daily allowance. On the other hand, you can make your own soup using low-sodium broth and fresh ingredients.

To lower your sodium intake, buy your vegetables fresh instead of from a can, and be sure to rinse all canned veggiesyou do have to remove excess sodium before eating. Half a cup of raw carrots has only 45 mg of sodium, and a cup of green beans has just 6 mg.You may also be able to find low-sodium versions of some canned foods or some with no salt added.

Flavor Packets and Condiments Are Teeming With Salt

Instead of using the salty flavor packets that comein boxes of macaroni and rice dishes, make your own flavorings with fresh ingredients. By using fresh herbs and spices, you can infuse plenty of flavor into your dishes without any additional sodium. Consider seasoning your meals with lemon juice, ground pepper, cumin, garlic, onion powder, and fresh herbs.

Also, be careful about pouring on condiments. Ketchup has about 150 mg of sodium per tablespoon (tbsp), and soy sauce can pack almost a whopping 1,000 mg of sodium per tbsp.You can also find lower-sodium versions of condiments like ketchup, mustard, and soy sauce.

Frozen Meals Can Be Freakishly Salty

The frozen foods section of your grocery store can be another hiding place for salt. A single slice of a frozen pizza can contain 720 mg of sodium — and who eats just one? A single serving of frozen meatloaf might have 900 mg.

All that excess salt causes your body to retain fluid, which will not only leaving you feeling bloated but can also lead to high blood pressure. Look for low-sodium options, or better yet, cook your own meals from scratch in bulk, and freeze leftovers for days you don’t feel like cooking.

Some Seafoods Are Saturated With Sodium

Seafood is a great addition to a heart-healthy diet. When prepared in a healthy way, seafood may help lower cholesterol, which in turn helps improve heart health. But you need to choose your seafood wisely, since options like shellfish and canned tuna fish are high in salt. Five oz of canned tuna has more than 300 mg of sodium, and 3 oz of frozen shrimp can have more than 400 mg. Better seafood choices include fresh tuna, salmon, halibut, and haddock.

Before putting any food in your grocery cart, follow this simple rule of thumb: “The bottom line on hidden food sources of sodium is to check your labels and choose products with less than 140 mg per serving,” says Brennan. And choose fresh, whole foods as often as possible.
