Foods high in Potassium, K
Potassium works in balance with sodium to regulate fluid inside and outside cells and to enable normal nerve signaling and muscle contraction, including the steady rhythm of the heart. Research has linked higher potassium intake to lower blood pressure and lower cardiovascular and stroke risk, particularly as part of an eating pattern that is also lower in sodium. Most people are more likely to fall short of the recommended intake for potassium than to get too much from food, since it is not a nutrient many diets emphasize, so this list can be a useful starting point for identifying foods that help close that gap. The ranking below reflects measured potassium per the amount analyzed, which means concentrated items such as cream of tartar and instant coffee or tea powders can appear unexpectedly high even though they are consumed in small amounts. Fruits such as potatoes and bananas, vegetables, legumes, and dairy products are generally the more realistic everyday sources to focus on. People with advanced kidney disease are a notable exception to the general "more is better" framing for potassium, since their kidneys may not clear excess potassium efficiently, so this list is best read alongside individual medical guidance for anyone in that situation.
