Does Tomato Have Potassium? Amounts By Type

Yes. Tomatoes are a steady source of potassium, and different forms pack different amounts. A raw medium tomato lands near 292 mg, while concentrated products like paste and puree deliver far more in a smaller scoop. If you use tomato juice or stewed tomatoes, a cup pushes you into the 500 mg range, which is handy when you’re building a meal that needs a mineral lift.

Tomato Potassium By Common Forms

Tomato Form	Standard Serving	Potassium (mg)
Tomato, raw	1 medium	292
Tomato paste, canned	1/4 cup	669
Tomato puree	1/2 cup	549
Tomato juice, 100%	1 cup	527
Stewed tomatoes, canned	1 cup	528
Tomato sauce, canned	1/2 cup	364

Use the table to pick what fits your plate. Paste and puree are the heavy hitters per bite, while raw and cherry styles bring flavor with fewer milligrams per forkful. If you’re seasoning jars or cans, scan the label for sodium first, then portion the tomato base for the potassium you want.

Why Potassium From Tomatoes Matters

Potassium helps muscles fire, nerves send signals, and your body balance fluids. It also works in tandem with sodium to keep blood pressure in a reasonable range. Many people overshoot salt at meals, so boosting potassium from produce helps even the score without adding calories. If sodium climbs in your week, aim for more tomatoes, beans, greens, and dairy to offset that swing.

That pairing matters for more than taste: dialing back salt and raising potassium often moves the needle for numbers at the cuff. If you’re watching salt, anchor meals around fresh tomato, no‑salt‑added sauce, or tomato juice, then season with herbs, citrus, and pepper. A simple caprese, a skillet shakshuka, or a veggie chili can nudge the balance the right way once you set your daily sodium limit.

How Tomato Prep Changes Potassium

Cooking And Concentration

Heat pulls out water, so cooked sauces and paste are more concentrated. That’s why 1/4 cup of paste brings a large hit, while the same volume of chopped fresh tomato lands far lower. Puree sits in the middle. If you simmer sauce down, you’re not making new minerals; you’re packing the same minerals into less water, which bumps milligrams per ladle.

Fresh Vs Canned Vs Juice

Fresh tomatoes are naturally low in sodium and give steady potassium with few calories. Canned sauce and puree vary a lot by brand; “no salt added” lines protect the potassium‑to‑sodium ratio, while classic jars can swing salty. Tomato juice sits near 527 mg per cup; low‑sodium bottles exist, and they’re a smart swap if you’re using juice as a snack or mixer. Stewed tomatoes hover around the same range per cup, which makes them an easy pantry tool for soups and stews.

How Much Potassium You Need And What %DV Means

On labels, the Daily Value for potassium is 4,700 mg. The %DV tells you how much a serving contributes toward that reference point. In daily planning, adults often aim for AIs set by expert panels: men 19+ at 3,400 mg, women 19+ at 2,600 mg, pregnancy at 2,900 mg, and lactation at 2,800 mg. Those targets explain why a single cup of tomato juice can land near a tenth of a day’s need.

For background on targets by age and life stage, see the NIH potassium fact sheet. When you read packages, the reference used for %DV comes from the FDA’s list of Daily Values; potassium sits at 4,700 mg on that table, which makes math easy on the fly. Here’s the source: the FDA Daily Value list.

Labels can be tricky. A jar that lists 360 mg potassium per 1/2 cup reads as about 8% DV, while a 1/4 cup of paste near 669 mg shows about 14% DV. Use %DV for a quick scan, then look at the sodium line next, since one salty serving can drown the advantage you’re getting from potassium.

Who May Need To Limit Or Seek Guidance

Some people need to limit potassium, including those with kidney disease and anyone taking certain drugs that raise potassium, like ACE inhibitors, ARBs, or potassium‑sparing diuretics. When care teams adjust meds, targets can shift fast. If that’s you, match your tomato choices to the plan you were given, and stick with the serving sizes listed here until your provider says otherwise.

Smart Shopping And Label Tips

Pick tomatoes that feel heavy for their size and smell fragrant at the stem. For cans and jars, look for “no salt added” or “low sodium.” Scan the Nutrition Facts: potassium listed in milligrams and as %DV, sodium right below, and the serving size up top. For paste, jars vary, so measure with spoons or 1/4 cup scoops when you want a larger hit. Rinse canned tomatoes if a recipe lets you drain; this step trims sodium while keeping most potassium in the solids.

Easy Ways To Get More Tomato Potassium

Build habits that slot tomatoes into meals you already make. Add sliced tomato to egg sandwiches. Stir a spoon or two of paste into lentil soup. Swap creamy dressings for a bright tomato‑garlic salsa. Roast wedges with olive oil and thyme to serve with fish or chicken. Toss halved cherry tomatoes into grain bowls with beans and herbs. Blend tomato with watermelon and lime for a chilled sip on hot days.

Women 19+ years	2,600	AI (NIH ODS)

Tomatoes Vs Other Potassium Foods

A raw medium tomato at roughly 292 mg trails a baked potato by a wide margin but still makes a dent. Orange juice lands near 496 mg per cup. Beans and greens often beat tomatoes gram‑for‑gram, yet tomatoes bring flexibility and low calories, so they show up often without crowding your plate. That mix is why many meal plans pair tomatoes with beans, fish, yogurt, or leafy sides.

Sample One‑Day Tomato Plan

Here’s a simple day that nudges potassium up with tomato at each meal: Breakfast, a veggie omelet with sliced tomato and a glass of low‑sodium tomato juice. Lunch, a turkey‑avocado sandwich stacked with tomato and a side of cucumber‑tomato salad. Dinner, whole‑grain pasta tossed in no‑salt‑added marinara bolstered with an extra spoon of paste. Snacks can include cherry tomatoes with cottage cheese or a small bowl of bean‑tomato chili. Mix and match with your own favorites.

Bottom Line On Tomato Potassium

Tomatoes do have potassium and the amount depends on the form you pick. Fresh brings steady milligrams with barely any sodium, sauces vary, and paste packs the most per scoop. If you eat for blood pressure, potassium‑rich tomatoes fit well once you balance salt in the rest of the menu. Want a deeper kitchen list to plan meals around pressure control?
