Mushrooms are a nutrient-dense food that provides a variety of health benefits. They are low in calories and contain protein, vitamins, minerals, and antioxidants. Mushrooms are also a good source of potassium, a nutrient that helps to regulate blood pressure and reduce the negative impact of sodium on the body. The amount of potassium in mushrooms varies depending on the variety and whether they are measured raw or cooked. White mushrooms, for example, contain 153 mg of potassium per 1/2 cup when raw and 276 mg per 1/2 cup when cooked.
| Characteristics | Values |
|---|---|
| Potassium Content | A cup of mushrooms contains around 223 mg of potassium. The potassium content varies with mushroom variety and whether it is measured raw or cooked. For example, 1/2 cup of uncooked, sliced white mushrooms weighs 48 grams and contains 111-153 mg of potassium. If cooked, then measured, 1/2 cup of white mushrooms weighs 78 grams and contains 276-277 mg of potassium. |
| Other Nutrients | Protein, vitamins (including B vitamins, vitamin C, vitamin D, and vitamin B6), minerals (including copper), and antioxidants. |
| Health Benefits | May help prevent numerous types of cancer, lower blood pressure, reduce the risk of developing serious health conditions such as Alzheimer's, heart disease, cancer, and diabetes, and improve weight loss. |

What You'll Learn
White mushrooms are a good source of potassium
The potassium content in mushrooms varies depending on the variety and whether they are measured raw or cooked. For instance, 1/2 cup of uncooked sliced white mushrooms (approximately 48 grams) contains around 153 mg of potassium. In comparison, the same quantity of cooked white mushrooms (approximately 78 grams) provides about 276 mg of potassium.
White mushrooms, in particular, stand out for their substantial vitamin C content, offering 2.5 times the required amount per calorie. They are also a rich source of selenium, vitamin D, and vitamin B6. Selenium plays a crucial role in preventing cell damage, while vitamin D supports cell growth, and vitamin B6 aids in the formation of red blood cells. These nutrients collectively contribute to a robust immune system.
In addition to their potassium content, white mushrooms offer a host of other health benefits. They are low in calories and provide dietary fiber, which may help lower the risk of developing type 2 diabetes and reduce blood glucose levels. Mushrooms also contain protein, vitamins, minerals, and antioxidants, which may offer protection against Alzheimer's, heart disease, cancer, and other serious health conditions.

Potassium's health benefits
Mushrooms are a rich source of potassium, a nutrient with several health benefits. Potassium is an essential mineral that acts as an electrolyte, helping to maintain the body's fluid balance. It also plays a crucial role in nerve function, as the movement of potassium ions out of cells and sodium ions into cells helps generate nerve impulses. A potassium-rich diet is associated with a reduced risk of cardiovascular disease, including heart disease and stroke. This is because potassium helps regulate blood pressure by lessening tension in blood vessels and counteracting the negative impact of sodium. Additionally, potassium may help prevent osteoporosis by reducing calcium loss through urine and may also protect against kidney stones.
However, it is important to maintain a balanced potassium intake, as both high and low levels can lead to health issues. Low potassium, known as hypokalaemia, can cause symptoms such as muscle weakness, abnormal heart rhythm, and paralysis. On the other hand, high potassium, or hyperkalaemia, is a serious and potentially life-threatening condition that may be caused by kidney disease or certain medications.
The recommended daily potassium intake is 2,600 milligrams (mg) for females and 3,400 mg for males. One cup of mushrooms contains around 223 mg of potassium, making them a good source of this essential mineral. Mushrooms are also a low-calorie food, providing dietary fibre, protein, and various vitamins and minerals, including vitamin D, B vitamins, and selenium, which offer additional health benefits.

The amount of potassium in white mushrooms
Mushrooms are a rich source of potassium, a nutrient that helps to reduce sodium's negative impact on the body. Potassium also helps to lower blood pressure by lessening tension in blood vessels. The potassium content in mushrooms varies depending on the variety and whether they are measured raw or cooked. For instance, 1/2 cup of uncooked, sliced white mushrooms (48 grams) contains 153 mg of potassium. On the other hand, 1/2 cup of cooked white mushrooms (78 grams) contains 276 mg of potassium. Similarly, 1 cup of fresh mushrooms contains 111 mg of potassium, while the same quantity when cooked contains 277 mg of potassium.
White mushrooms are also the only type of mushroom with a substantial amount of vitamin C, containing 2.5 times the required amount per calorie. In addition, mushrooms are a good source of B vitamins, including thiamine, riboflavin, B6, and B12. They also contain protein, copper, and other minerals and antioxidants.
The American Heart Association (AHA) recommends eating more foods containing potassium while reducing salt intake. The daily recommended intake of potassium is 2,600 milligrams (mg) for females and 3,400 mg for males. However, it is important to note that daily goals can vary for each individual, and people with certain conditions, such as kidney disease, may need to adjust their potassium consumption accordingly.

Other nutrients in white mushrooms
White mushrooms are the most cultivated type of mushroom in the world and are incredibly popular in the United States. They have a mild flavour and a smooth cap and can be enjoyed in a variety of ways, including fresh, frozen, canned, dried, or powdered.
Like most mushrooms, white mushrooms are low in calories but packed with essential nutrients. A cup of sliced raw mushrooms, weighing 70 grams, provides 20-30 grams of dietary fibre, depending on sex and age. White mushrooms are also a natural, non-animal source of vitamin D2, which is capable of increasing blood levels of vitamin D as effectively as a supplement. Vitamin D2 is converted by the body into its active form, which aids in calcium absorption, promoting strong bones.
White mushrooms also provide vitamin B12, typically found in animal-based foods, making them a valuable nutrient source for vegetarians. They also contain other B vitamins, including thiamine, riboflavin, and B6. Additionally, white mushrooms contain protein, with a higher content than most vegetables, making them a helpful supplement in meals.
White mushrooms also contain ergothioneine and beta-glucan, which may reduce the risk of cardiovascular disease by reducing blood cholesterol levels. Beta-glucan forms a gel-like substance during digestion, binding cholesterol and preventing its absorption into the bloodstream.

Preparing and cooking white mushrooms
White mushrooms are a great source of potassium, with one cup containing around 223 mg of this essential mineral. Preparing and cooking them correctly can enhance their flavour and ensure they retain their nutritional value. Here is a step-by-step guide to help you prepare and cook white mushrooms:
Selecting and Storing Mushrooms
When buying fresh white mushrooms, choose ones that are firm, dry, and unbruised. Avoid any that appear slimy or withered. Store the mushrooms in the refrigerator until you are ready to cook them.
Cleaning Mushrooms
It is generally recommended not to wash mushrooms as this can affect their texture and colour. Instead, use a damp paper towel to gently wipe off any visible dirt.
Cutting Mushrooms
Remove any hard stems and cut or tear the mushrooms into similarly sized pieces. This ensures even cooking and a consistent texture in your final dish.
Cooking Mushrooms
The key to successfully cooking white mushrooms is to avoid overcrowding the pan. Cook the mushrooms in a single layer in a wide skillet or pan to allow them to brown rather than steam. You can use olive oil, butter, or a combination of both for cooking. Heat the fat of your choice over medium heat, and then add the mushrooms. Allow them to cook until they turn golden brown, stirring occasionally.
Seasoning Mushrooms
It is best to season mushrooms towards the end of cooking. Salt draws out moisture, so adding it too early can make the mushrooms mushy and prevent browning. After the mushrooms have browned, season with salt and pepper to taste. You can also add aromatics such as fresh thyme, rosemary, or sage, and ingredients like garlic and lemon zest for additional flavour.
Storing Cooked Mushrooms
Cooked mushrooms can be stored in an airtight container in the refrigerator for up to four days. They can also be frozen for up to six months.
