According to the “2020-2025 Dietary Guidelines for Americans,” potassium is an under-consumed nutrient, and many of us don’t get enough of it from our daily diets.
Potassium, like other nutrients, helps our bodies function properly. Potassium is a mineral that helps our bodies perform a number of functions, like muscle contractions, fluid regulation, and mineral balance in cells. It also helps us maintain normal blood pressure by limiting the effect of sodium.
Bananas are probably the first food that comes to mind when you think about potassium. But potassium is found in many foods, such as leafy greens, tomatoes, eggplant, pumpkin, potatoes, carrots, and beans. It's also found in dairy products, meat, poultry, fish, and nuts.
Food is the best way to get potassium. By eating a variety of foods every day, you can meet your potassium needs as well as get other important vitamins and minerals that promote health. However, some people may need supplements for a little extra help.
Keep in mind that not everyone needs more potassium. Some people may even need to decrease their potassium intake because of certain health conditions. So, it’s important to always talk to your healthcare provider before adding supplements.
Whether you are increasing or reducing your potassium intake, you should learn which foods contain potassium and how much. Always check the Nutrition Facts Label when you are grocery shopping. Food manufacturers are now required to include potassium in the Nutrition Facts Label.
Here are just a few potassium-rich foods:
1 medium baked potato with skin: 930 milligrams
1 cup cooked spinach: 840 milligrams
