Once upon a time, the ashes that remained after burning wood were considered a valuable commodity. Stirred into a pot of water and then leached, the resultant “pot ash” could then be used in the manufacture of textile dyes, soap, fertilizer, glass, and gunpowder, as well as many other products. It wasn’t until 1807 that the chemical makeup of potash was discovered by running an electrical current through it and observing the formation of a pure element, which was named potassium in a nod to its origins.
While potassium and its salts are critical for the world of industry, the mineral potassium is also very important nutritionally. For some reason, bananas are the food most commonly associated with the element, even though it’s found in a diverse range of foods, many of them whole plant foods.
Despite its availability in many foods, potassium is one of the nutrients of public health concern in the US because so few people actually manage to get enough of it. The US dietary guideline for potassium for adult females is 2,600 mg per day — almost 300 mg per day more than the average woman consumes. The 3,400 mg that males are told to aim for daily is likewise around 300 mg more than the average potassium US men get.
The good news is, just one or two additional servings of potassium-rich foods per day could totally eliminate both gaps.
But why do you need potassium in the first place? What happens when you don’t get enough? And what does it take to get adequate amounts from the food you eat?
Stay tuned, and you’ll get answers to those questions, along with seven potassium recipes to make it easy and delicious to meet your potassium needs.
Why Do You Need Potassium?
Potassium, designated as K on the periodic table, is an essential mineral required to keep your body running efficiently. It functions as an electrolyte, which is any substance that conducts electricity when dissolved in water or melted, and which is crucial for any bodily function that relies on the sending and receiving of electrical impulses.
Potassium, in particular, helps keep your body hydrated and your nervous system healthy. It plays a vital role in keeping your heart beating steadily, your muscles working smoothly, and your nerves firing properly.
By regulating your body’s fluid balance, potassium also supports healthy blood pressure levels. It can also keep your kidneys functioning properly, protect the health of your bones, and regulate your blood glucose level. In short, potassium is crucial for just about every aspect of your health and well-being.
Important digression here: If you’re worried about your potassium levels and you currently have kidney disease, please check with your health care provider before loading up on potassium, either in food or supplement form. There’s a condition, hyperkalemia, that consists of dangerously high levels of potassium in the blood, caused by kidneys that lack the ability to filter the element.
Aiming for High Potassium, Low Sodium Foods
So far, I’ve been talking about potassium in a bit of a vacuum, nutritionally speaking. But to really understand the role that potassium plays in your body, you have to look a little more holistically. Because potassium works together with another element, sodium, to do an extremely important job: maintain fluid equilibrium across cell walls.
How they do this is kind of complicated, involving something called “membrane potential,” which has to do with the difference in electrical charge between the inside and outside of your cells that determines whether fluids move in or out of those cells.
The upshot for your health, though, is quite straightforward: potassium blunts some of the effects of sodium to keep the fluids in a healthy balance. That way, your cells don’t blow up like overinflated balloons, or collapse like punctured ones.
In a perfect food world, this process would happen naturally, and you wouldn’t need to think about it. But because the modern industrialized diet delivers far more sodium than potassium, your potassium/sodium ratio may be skewed in the direction of not enough potassium. This can increase your risk of high blood pressure, cardiovascular disease, and type 2 diabetes.
Conversely, limiting your sodium intake by minimizing processed, packaged, and fried foods, all of which tend to be high in sodium, can balance the potassium/sodium teeter-totter from the other direction.
Top Potassium Foods
While you may be tempted to pop a pill if you’re low in potassium, there are good reasons to get it from food if possible — the main one being that potassium-rich foods are also packed with other vital nutrients like vitamins, minerals, and antioxidants that work together to support your health.
So what are the potassium heroes of the food world? Here are some excellent sources of the mineral, along with their potassium and sodium levels per 100-gram serving (which, for the visually minded, is about the size of four button mushrooms or a quarter block of tofu).
| Bananas: | 358 mg potassium | 1 mg sodium |
| Oranges: | 181 mg potassium | 0 mg sodium |
| Sweet Potatoes: | 337 mg potassium | 55 mg sodium |
| Spinach: | 558 mg potassium | 79 mg sodium |
| Tomatoes: | 237 mg potassium | 5 mg sodium |
| Papaya: | 182 mg potassium | 8 mg sodium |
| Butternut Squash: | 352 mg potassium | 4 mg sodium |
| Avocado: | 485 mg potassium | 7 mg sodium |
| Black Beans: | 355 mg potassium | 1 mg sodium |
You don’t have to memorize this list or get it tattooed on your forearm to take advantage of potassium-rich foods. If you adopt the general strategy of opting for fresh fruits, vegetables, and whole grains, and flavor them with herbs and spices rather than pouring on the salt, you’ll likely get all the potassium you need.
