Got dry hair or skin? It could be due to potassium, or lack of it

Hear the word potassium, and most of us probably think bananas. And while it’s true that bananas are certainly very high in potassium – according to the USDA this tasty meal in one contains around 422 mg in each medium-sized fruit – they are by no means the only way (or even the best way) to get this important mineral into your system.

But before we start looking at how to get enough potassium each day, let’s talk about what potassium is and what it does for us.

What is potassium?

Potassium is one of the most important minerals in the body. Along with chloride and sodium, potassium is a vital electrolyte: minerals in your blood, urine, and bodily fluids that contain an electric charge.

Electrolytes are what cells use to communicate with each other, so potassium provides a myriad of functions, including the maintenance of normal body growth, breaking down of carbohydrates, building of proteins, proper functioning of the heart and kidneys, lowering of blood pressure, protection against strokes, and enabling growth of muscle tissues. Because it regulates fluid balance potassium is especially important for maintaining hydrated skin and healthy hair.

How do we get potassium?

Potassium is an essential nutrient because your body can’t produce it. Therefore, we need to get it through diet. The recommended daily needs, also known as the Daily Value (DV), for healthy adults is 4,700mg, and if you’re not getting enough potassium, it could lead to fatigue, muscle cramps, heart palpitations, dizzy spells and dry hair and skin.

Mainly regulated by the kidneys, potassium is primarily lost in urine, but you will also lose potassium when you sweat, so it’s a good idea to keep your potassium intake up over the summer months.

Fortunately, this mineral is readily available in foods like bananas, avocados, watermelon, beets, beans, potatoes, and salmon, so it’s very easy to get enough potassium into your body through the foods you eat.

If you’re worried about dry hair or skin, you can adjust your diet to make changes from the inside-out. So, why not incorporate some of wonder foods into your diet to ensure you’re getting enough potassium, starting with the humble and often maligned potato.

Potassium power packs

Yes, the poor old potato often doesn’t get as much nutrition attention as it deserves.

One medium potato delivers 610 mg of potassium, or roughly 17% of the daily value (DV). That’s about 40% more potassium than you’ll find in a banana, which only contains 422 mg, or 9% DV.

However, one single baked potato (with the skin on as much of a potato’s potassium is in the skin) can deliver over 1,000 milligrams of potassium, which is twice what a single banana can bring to the party. Top it with some non-fat yogurt, which also contains potassium, and green onions and you get a relatively low-calorie and heart-healthy side dish.
