Potassium rarely makes headlines, yet it appears in many everyday foods in generous amounts. Potatoes, spinach, beans, bananas, and yogurt all carry hundreds of milligrams per portion, and most people meet potassium through varied meals rather than single hero foods. This free explorer lists potassium per portion for fruits, vegetables, dairy, fish, and legumes, so you can compare groups side by side. You pick a group and a sort order, and the tool ranks foods from lowest to highest potassium or the other way round. It is general education only, not medical advice, and it suits anyone learning where potassium hides.
Vegetables lead the potassium list, and potatoes lead the whole explorer. A medium potato gives about 900 milligrams of potassium, while a cooked cup of spinach gives about 840 milligrams. Sweet potatoes give about 540 milligrams per medium root, and tomatoes give about 300 milligrams each, so everyday vegetables cover a wide range. Cooking methods matter little for ranking, though boiling in large water can lose some potassium, while baking or steaming keeps more. A potato or a green vegetable at dinner already makes a strong potassium contribution.
Fruits and legumes add potassium in sweet and filling portions. Bananas give about 420 milligrams per medium fruit, avocados about 490 milligrams per half, and orange juice about 500 milligrams per cup. Cooked beans give about 600 milligrams per cup, which makes beans a double win for fiber and potassium together. Fruit potassium comes with natural sugars and fiber, so whole fruit beats juice for fullness even when juice lists similar potassium. A banana as a snack or beans in a main dish both lift daily potassium without effort.
Dairy and fish contribute potassium in smaller but regular amounts across meals. Yogurt gives about 300 milligrams per 170 grams, which pairs potassium with calcium and protein in one snack. Salmon gives about 400 milligrams per 100 grams, adding potassium to a protein-rich main dish. These amounts look modest beside potatoes, yet they appear in meals people already eat, so they stack across a day. The explorer keeps all groups on one scale so modest contributors stay visible instead of disappearing behind the leaders.
Potassium balance depends on the whole diet pattern, not on one food or one day. Varied meals with vegetables, fruits, legumes, and dairy usually supply potassium steadily, while diets built on highly processed foods tend to supply less. Salt substitutes and supplements can add potassium quickly, so they deserve caution and professional advice rather than casual use. People with kidney conditions or medicines that affect potassium need personal guidance, because more potassium is not better for everyone. This explorer teaches food sources only, and it never replaces medical advice about potassium intake.
Portion size shapes potassium totals more than most shoppers expect. A medium potato and a large potato differ by hundreds of milligrams, while half an avocado and a whole avocado differ by about 490 milligrams. The explorer lists clear portions, so compare them with your real servings before judging a food. Eating a vegetable at two meals beats eating a huge portion once, because steady intake across the day suits the body better. Use the explorer to find foods you already enjoy in each group, then eat them a little more often.
Use the explorer to add one potassium-rich food to your week from a group you usually skip. Try a baked potato, spinach at dinner, beans in soup, or yogurt with fruit, and keep the foods you already like. Repeat the check when you shop, since portions and varieties change potassium values. Remember that this tool offers general education only, not personal nutrition advice, and a clinician can help with specific potassium needs or restrictions. Varied, everyday food beats a single potassium hero every time.
