Mushrooms might have a specific texture and taste that’s not to everyone’s liking, but they’re quickly becoming more and more popular. This delicious food makes a wonderful addition to any diet from soups through sauces to even side dishes as it’s highly nutritious and low in calories.
But if you’re following a diet with special requirements, it’s important to know whether mushrooms might make give you unpleasant symptoms.
For example, you should know mushrooms’ potassium content if you struggle with kidney issues. So, are mushrooms high in potassium?
Are Mushrooms High In Potassium?
Mushrooms contain a reasonably high amount of potassium so they can’t be considered a low-potassium food. As a result, they might not be particularly suitable for a kidney-friendly diet, especially if you tend to consume more than the standard serving in one sitting.
On the bright side, they are high in essential nutrients and minerals, so they can help protect your digestive system from inflammation. So, it might be a good idea to add small amounts of mushrooms to your diet.
How much potassium is in mushrooms?
A one-cup serving of raw, white mushrooms contains around 223mg of potassium. To be safe for a kidney-friendly, low-potassium diet, the food needs to contain less than 200mg of potassium, which means that you should limit how often you consume mushrooms.
On the other hand, they are loaded in nutrients and beneficial plant compounds, making them a wonderful addition to a healthy, balanced diet.
There is a wide variety of mushrooms available on the market, and some of the most popular ones, aside from white mushrooms, include portobello mushrooms. While still healthy and nutritious, these are even higher in potassium as just one cup contains 416mg of this mineral.
While most people don’t consume that many mushrooms in one sitting, it’s still a lot, so you should keep that in mind if you follow a particularly low-potassium diet.
Are mushrooms healthy?
Mushrooms are a very nutritious food. They contain very few calories – only about 15 calories in one cup. In spite of that, they’re still very nutritious, providing you with a lot of riboflavin, also called vitamin B2.
This nutrient helps your body break down carbohydrates, proteins, and fats and produce energy to be used by your body. Riboflavin is also responsible for protecting your blood cells, digestive tract lining, and other vital organs. Because of that, it’s important to take in enough of this nutrient.
Mushrooms are also high in beneficial antioxidants. These compounds not only help flush free radicals out of your body but also prevent oxidative damage to your cells.
Oxidative damage often leads to premature death and age-related issues, so a diet high in antioxidant-rich foods can help prevent these issues. In addition, studies show that antioxidants help protect your health and lower the risk of a heart attack.
Eating mushrooms also helps you stock up on beta glucan, which is a soluble dietary fiber. It has been proven to have effects similar to insulin, making it a great nutrient for treating and preventing type 2 diabetes.
It might also contribute to good heart health and regulating blood sugar levels, which are also linked to diabetes. Oyster and shiitake mushrooms contain the most effective beta glucans, so you may want to include them in your diet.
Mushrooms are an excellent source of copper – a mineral that helps your body make red blood cells, which deliver oxygen all over your body. Copper also contributes to various processes in the body, such as keeping your bones and nerves healthy.
Cooking mushrooms lowers their copper content slightly, but they still contain almost one-third of your daily recommended need for this mineral even after boiling them.
When consuming mushrooms, it’s important to buy them in the grocery store and refrain from picking them yourself. While there are only a handful of poisonous mushrooms, it’s very hard to tell, which ones are safe to eat, and which ones aren’t.
Because of that, it’s best not to try and pick mushrooms yourself and get them from a reputable place where they were picked by people who are experts in mushrooms.
Can you take in too much potassium from mushrooms?
All types of mushrooms are high in potassium, which means you should limit how much of this food you consume on a low-potassium diet. Some mushroom varieties are even higher in potassium, so it might be best to eliminate these from your diet altogether to avoid any unpleasant symptoms and health issues.
On the bright side, if you can tolerate small amounts of mushrooms without any issues, it’s a good idea to incorporate them into your diet as they contain essential antioxidants and plant compounds that help you stay healthy.
Depending on the variety of mushrooms, you may take in less or more potassium. This is important to note since some people might have to control their potassium intake more strictly than others.
For example, enoki, brown, oyster, and portobello mushrooms are rather high in potassium, so it might be a good idea to eliminate them from your diet if you need to control your potassium intake very carefully. On the other hand, mushrooms like shiitake and maitake are lower in potassium, so they might be safer for you to consume.
Is cream of mushrooms high in potassium?
A single serving of one cup of cream of mushrooms soup contains around 74mg of potassium, making it better for a low-potassium diet than raw mushrooms.
On the other hand, cream of mushrooms is less nutritious and higher in calories than fresh mushrooms, which can lead to weight gain and a deficiency of certain nutrients, especially if you consume it in large quantities.
As a result, it’s best to eat cream of mushrooms rarely, particularly if you’re consuming store-bought, canned versions as they tend to be loaded with sodium, which is bad for your health.
Mushrooms are a very nutritious, low-calorie food that helps you stay healthy. Unfortunately, most types of mushrooms are high in potassium, which means that eating too many of them may lead to unpleasant health issues.
Because of that, it’s important to pay attention to how much of this type of food you take in, particularly if you have kidney issues.
