Most fast food meals pack 1,000 to 2,000 mg of sodium, which can eat up nearly an entire day’s worth in a single sitting. But every major chain has options that come in well under 600 mg, and a few simple ordering tweaks can cut hundreds of milligrams from almost any meal. The American Heart Association recommends no more than 2,300 mg of sodium per day, with an ideal target of 1,500 mg for most adults. That means a single fast food meal ideally shouldn’t exceed 500 to 750 mg.
The Lowest Sodium Picks by Chain
Not all fast food is created equal when it comes to salt. Here’s where to find the best options across the most popular chains.
Wendy’s offers one of the single best low-sodium items in all of fast food: a plain baked potato at just 40 mg of sodium. That’s remarkably low for any restaurant item, and it gives you a filling base you can pair with other choices. Their apple bites side is another smart add-on.
Subway lets you control what goes on your sandwich, which is a major advantage. A 6-inch Veggie Delite on Italian bread comes in at 310 mg of sodium. Italian and Hearty Italian breads are tied for the lowest sodium among Subway’s bread options at 290 mg per 6-inch serving. Their kids meal turkey breast sandwich runs about 460 mg, and the kids roast beef sits at 410 mg. Choosing mustard over high-sodium dressings and loading up on vegetables keeps things in check.
Burger King’s Whopper Jr. is one of the lighter burger options at 390 mg of sodium, which is notably lower than most fast food burgers its size. For comparison, their 9-piece chicken fries hit 850 mg, more than double. Skipping pickles and ketchup would shave off even more.
McDonald’s basic Hamburger contains 490 mg of sodium. That’s not low by grocery store standards, but it’s one of the more reasonable options on a fast food burger menu. The Filet-O-Fish comes in at 590 mg. Avoid the McDouble if sodium is a concern: it jumps to 850 mg.
Chick-fil-A’s Grilled Nuggets contain 440 mg of sodium, a meaningful improvement over their classic breaded nuggets. Grilling rather than breading tends to reduce sodium because the breading and frying process adds salt at multiple stages.
Panda Express can work if you choose carefully. Broccoli Beef and Eggplant Tofu are both among the lowest sodium entrees at 520 mg each. Pair either one with a half order of brown rice at just 7.5 mg of sodium, and you have a full plate that stays under 530 mg total. Avoid the fried rice if you can; even a quarter order adds 212 mg.
Why Sides and Drinks Matter More Than You Think
The entrée gets all the attention, but sides can quietly double the sodium in your meal. Regular french fries at most chains add 200 to 400 mg. A packet of ketchup adds another 150 mg or so. Ranch dressing or barbecue sauce can tack on 200 to 300 mg per serving. That means a “reasonable” burger with fries, ketchup, and a dipping sauce can easily cross 1,200 mg.
Swapping fries for a baked potato, a side salad with oil and vinegar, or fruit cups can eliminate 300 mg or more from your total. Plain water or unsweetened drinks add zero sodium, while some fountain drinks carry small amounts.
Ordering Tricks That Cut Sodium Fast
You don’t always need to pick a different item. Sometimes you just need to order the same item differently. The CDC recommends two straightforward requests: ask that no salt be added to your meal, and order vegetables or fruit as your side instead of fries.
Asking for fries with no added salt is a well-known trick that works at McDonald’s, Burger King, and Wendy’s. Since the salt is applied after frying, this is an easy step for the kitchen and can cut 100 to 200 mg instantly. You’ll also get a fresh batch, since they have to make them to order.
Condiments are the other big lever. Pickles, mustard, ketchup, mayonnaise, and special sauces all contribute significant sodium. Ordering a burger “plain” or specifying “no pickles, no ketchup” removes sodium that isn’t adding much nutritional value. At Subway, skipping the cheese and choosing oil and vinegar over creamy dressings makes a real difference.
Choosing smaller sizes helps too. A Whopper Jr. at 390 mg is far easier to fit into a low-sodium day than a full Whopper. Kids meals at Subway come in under 500 mg for both the roast beef and turkey breast options. Smaller portions mean less of everything, including salt.
What “Low Sodium” Actually Means
The FDA defines “low sodium” as 140 mg or less per serving. By that standard, almost nothing on a fast food menu qualifies as truly low sodium. Wendy’s plain baked potato at 40 mg is a rare exception. “Reduced sodium” means at least 25% less than the regular version, which some chains offer for specific sauces or sides.
The practical goal isn’t finding a “low sodium” labeled fast food meal. It’s assembling a combination that keeps your total meal under 600 to 750 mg, leaving room for the rest of your day. A Whopper Jr. with no pickles, a side salad, and water could realistically land around 400 to 500 mg. A Subway Veggie Delite with vegetables and oil comes in around 310 mg. Panda Express broccoli beef over brown rice totals roughly 530 mg.
Best Overall Combinations Under 600 mg
- Wendy’s: Plain baked potato (40 mg) plus a small side, leaving enormous sodium headroom
- Subway: 6-inch Veggie Delite on Italian bread (310 mg), with vegetables and oil and vinegar
- Burger King: Whopper Jr. without pickles or ketchup (under 390 mg) with a side salad
- Panda Express: Broccoli Beef with half-order brown rice (approximately 528 mg)
- Chick-fil-A: Grilled Nuggets (440 mg) with a fruit cup instead of fries
- McDonald’s: Hamburger (490 mg) with apple slices instead of fries
The common thread across all of these: skip the breading when you can, choose grilled over fried, replace fries with a non-salted side, and go easy on condiments. Those four habits can cut 300 to 500 mg of sodium from a typical fast food meal without requiring you to give up fast food entirely.
