Mushrooms are a great source of dietary fiber, protein, vitamins, and minerals. They are also known for their antioxidant properties. However, the cooking process can affect the nutritional content of mushrooms. Frying and boiling mushrooms can lead to a significant loss of proteins and antioxidants. On the other hand, grilling and microwaving mushrooms have been found to preserve most of their nutritional content. This is because the high temperatures of frying and boiling cause the soluble substances in mushrooms to leach into the water or oil, reducing their nutritional value. When grilling mushrooms, adding a few drops of olive oil can further enhance their antioxidant properties. Additionally, shorter cooking times help retain more nutrients in mushrooms. So, the next time you cook mushrooms, consider grilling or microwaving them to get the most out of their nutritional benefits!

What You'll Learn
Microwaving and grilling mushrooms retain the most nutrients
Mushrooms are a valuable health food, with significant amounts of dietary fibre, protein, vitamins, and minerals. However, the cooking process can negatively affect their nutritional content. A study by researchers from the Mushroom Technological Research Center of La Rioja in Spain evaluated the influence of different cooking methods on the nutritional profiles of four cultivated mushroom species: white button, shiitake, oyster, and king oyster mushrooms. The results showed that frying and boiling mushrooms led to severe losses in protein and antioxidant compounds, while microwaving and grilling them preserved most of their nutritional value.
When mushrooms are fried or boiled, the soluble substances in the mushrooms are leached into the water or oil, significantly reducing their nutritional value. On the other hand, microwaving and grilling mushrooms increase the content of polyphenols and antioxidant activity, with no significant losses in nutritional value. In fact, grilling mushrooms with a small amount of olive oil can even improve their antioxidant capacity.
The best way to cook mushrooms in the microwave is to place sliced mushrooms in a microwave-safe bowl or container, cover, and cook for 2-3 minutes on high, stirring once. If the mushrooms are not tender enough, cook in additional 30-second bursts until done. This method is ideal for mushrooms as they are very juicy, and you don't need to add any extra ingredients.
Grilling mushrooms is also a simple process. Simply place the mushrooms on a grill with a little olive oil and salt for flavour and all their nutritional value. This cooking method is especially good for portobello mushrooms, which can be grilled whole for use in burgers.

Frying and boiling mushrooms reduces their nutritional value
Mushrooms are a great source of fibre, protein, vitamins, and minerals. However, the cooking process can significantly impact their nutritional value. Frying and boiling mushrooms are said to reduce their nutritional value.
According to researchers from the Mushroom Technological Research Center of La Rioja in Spain, the cooking process can negatively affect the composition, antioxidant capacity, and nutritional content of mushrooms. The researchers evaluated the effects of boiling, microwaving, grilling, and frying white button, shiitake, oyster, and king oyster mushrooms, which are the most commonly consumed varieties. They found that frying and boiling mushrooms resulted in a severe loss of protein and antioxidant compounds.
Irene Roncero, one of the study's authors, attributed the loss of nutrients in fried and boiled mushrooms to the leaching of soluble substances in the water or oil. This can significantly influence the nutritional value of the final product. In contrast, grilling and microwaving mushrooms were found to preserve their nutritional properties, with no significant losses in nutritional value.
So, if you're looking to retain the most nutrients from your mushrooms, it's best to avoid frying or boiling them. Instead, opt for grilling or microwaving as healthier alternatives that will preserve the nutritional benefits of these fungi. By cooking mushrooms in a way that retains their nutritional value, you can maximize the health benefits they offer while still enjoying their delicious taste.

White button mushrooms are a good source of copper
Mushrooms are extremely nutritious and good for your health. They contain various vitamins, minerals, and antioxidants. They are the only vegan, non-fortified dietary source of vitamin D, and also contain vitamin B, selenium, and zinc.
White button mushrooms are a great source of vitamin B7 (biotin), vitamin B2 (riboflavin), vitamin B3 (niacin), and vitamin B5 (pantothenic acid). They are also an excellent source of copper, providing 34% of the daily value per 1-cup serving. Copper is a trace mineral that is essential for all living organisms. It is required for energy production, iron transport, nervous system function, cholesterol metabolism, bone and connective tissue production, and immune system function. A copper deficiency can lead to anemia, an increased risk of infections, weak bones, joint pain, and neurological issues.
White button mushrooms are also a good source of ergothioneine, a nutrient sometimes known as the "longevity vitamin". They contain more than 50% of the daily value of this nutrient.
To get the most nutritional value out of your mushrooms, it is best to grill or microwave them. Frying and boiling mushrooms can lead to a loss of protein and antioxidant compounds.

Portabella mushrooms are a good source of vitamin D
However, it is worth noting that many commercial mushrooms are grown in dark indoor spaces, so they do not always contain significant amounts of vitamin D. Therefore, it is important to check the mushroom package label to see if they have been exposed to UV light. If you are able to obtain mushrooms that have been exposed to UV light, it is still important to consume them before the 'best-before' date, as vitamin D2 levels may decrease with time.
When cooking portabella mushrooms, it is recommended to grill or microwave them, as frying and boiling have been shown to result in a severe loss of protein and antioxidant compounds. Portabella mushrooms are very versatile and can be used in a variety of dishes, such as pasta, sauces, stir-fries, and even as a meat substitute in burgers.

Crimini mushrooms are a good source of selenium
Crimini mushrooms, also known as cremini mushrooms, are a type of Agaricus bisporus mushroom. They are smaller in size compared to portabella mushrooms but share similar characteristics. Crimini mushrooms have a firm texture and an earthy flavor, making them a versatile ingredient in various dishes. They can be eaten raw or cooked and are commonly used in salads, grilled dishes, or as a side dish.
The selenium content in crimini mushrooms is notable, with just four mushrooms containing 20.8 mcg of selenium, which equates to 38% of the recommended daily value (DV). This makes them a significant contributor of selenium to the diet, enhancing the body's ability to fight infections and diseases.
In addition to selenium, crimini mushrooms are also a good source of other essential nutrients. They contain B vitamins, including riboflavin, niacin, and pantothenic acid, which are important for energy production and nervous system function. Crimini mushrooms are also a source of vitamin D, which is crucial for bone health and immunity. However, the vitamin D content in crimini mushrooms depends on their exposure to sunlight or UV light during their growth.
To retain the most nutritional value when cooking crimini mushrooms, it is recommended to grill or microwave them. Frying and boiling mushrooms can lead to a significant loss of protein, antioxidants, and other beneficial compounds. Therefore, grilling or microwaving is the best way to prepare crimini mushrooms to maximize their nutritional benefits, especially their selenium content.
