Best foods for potassium rich

Potassium is the mineral that keeps the rest of your diet honest. It works against sodium to regulate fluid balance, supports normal blood pressure, and helps nerves fire and muscles contract, including the heart. Most people fall short of the recommended intake not because potassium is rare, but because it clusters in whole plant foods that get crowded out by processed options. The 195 foods that qualify here all deliver a meaningful amount of potassium, measured in milligrams per serving, without leaning on supplements or fortification.

We rank by our Nutrient Density Score, a 1 to 100 relative measure of nutrition per calorie, rather than by raw potassium alone. That is why leafy greens dominate the top: Spinach, raw and Parsley, fresh both post a perfect 100, carrying 558 mg and 554 mg of potassium while staying almost calorie-free. Beet greens, raw push higher still at 762 mg, and Dill weed, fresh reaches 738 mg.

One realistic caveat: the highest-scoring foods are herbs and greens eaten in small amounts, so a garnish of thyme contributes less than its per-100-gram figure suggests. Build volume with the greens, and treat the herbs as concentrated extras. This is a reference, not medical advice, and potassium needs vary, especially for anyone managing kidney function.
