What You'll Learn
Calorie content of raw vs. cooked mushrooms
Mushrooms are a low-calorie food, providing the body with several nutrients, such as copper, potassium, iron, and B vitamins. The calorie content of mushrooms varies depending on whether they are raw or cooked, as well as the type of mushroom and its size.
In general, a cup of raw mushrooms (approximately 70 grams) contains around 15 calories. They are also a good source of fibre, particularly the soluble fibre beta-glucan. Raw mushrooms have a low glycemic index, indicating a minimal impact on blood glucose or insulin response due to their low carbohydrate content. Additionally, raw mushrooms are higher in sugar compared to cooked mushrooms, with 2.1 grams of sugar per serving.
When cooked, mushrooms lose a significant portion of their nutrients, especially water-soluble vitamins. To make a proper comparison between raw and cooked mushrooms, it is recommended to use the same number of mushrooms rather than measuring weight or volume. For example, six large raw white mushrooms have 24 calories, but cooking them reduces the calorie count to 20.
It is worth noting that dried mushrooms tend to have higher calories and nutrient concentrations than raw mushrooms. Canned mushrooms may also have slightly higher calorie content and significantly higher sodium levels due to additives.

Calories in canned mushrooms
Canned mushrooms are a convenient and versatile ingredient, but their nutritional profile differs slightly from fresh mushrooms. While still a low-calorie food option, canned mushrooms typically contain slightly more calories than their fresh counterparts.
A cup of raw mushrooms, weighing around 70 grams, provides approximately 15 calories, along with essential micronutrients like copper, potassium, iron, and B vitamins. In contrast, canned mushrooms generally have a higher calorie count, with one source stating that they contain 33 calories per serving. This difference in calorie content between fresh and canned mushrooms is likely due to the additives and processing involved in canning.
Fresh mushrooms, particularly those grown locally, are often recommended for their superior nutritional attributes. They offer slightly lower calories, significantly less sodium, and higher protein content. For instance, fresh white Canadian mushrooms have 29 calories per serving, compared to 33 calories in their canned counterparts. Additionally, fresh mushrooms are a good source of valuable micronutrients, including riboflavin, niacin, copper, pantothenic acid, and selenium. They are also one of the few natural sources of Vitamin D, which is crucial for bone health and immune system support.
However, it is worth noting that the decision between fresh and canned mushrooms ultimately depends on personal preferences and cooking requirements. Canned mushrooms are convenient and blend well into cooked dishes, adding their earthy flavour to stews, casseroles, and chillies. They are readily available and can be a valuable ingredient in various recipes.
In summary, while canned mushrooms may have slightly more calories and sodium than fresh mushrooms, they can still be a nutritious and tasty addition to your meals, depending on your specific needs and culinary preferences.

Nutritional value of mushrooms
Mushrooms are a low-calorie food packed with essential vitamins, minerals, and antioxidants. They are a good source of copper, potassium, phosphorus, iron, and B vitamins. The B vitamins in mushrooms include thiamine, riboflavin, B6, and B12. They also contain niacin (vitamin B3) and pantothenic acid (vitamin B5). A cup of sliced raw mushrooms contains 11.9 micrograms (mcg) of folate, a B vitamin that is particularly important during pregnancy.
Mushrooms are also a source of protein, with 2.2 grams per cup. They contain a substance called ergosterol, which can be transformed into vitamin D with exposure to ultraviolet light. The amount of vitamin D in mushrooms varies widely and depends on their exposure to UV light. Some mushrooms, such as chanterelles and morels, can contain up to 1200 IU of vitamin D per 3.5-ounce serving when fresh and wild. Mushrooms grown in darkened conditions, such as white button, shiitake, and oyster mushrooms, typically contain less vitamin D. However, exposing these mushrooms to sunlight or UV lamps can significantly increase their vitamin D content.
In addition to their nutritional content, mushrooms have been associated with various health benefits. They are considered a heart-healthy food choice as they may help lower blood pressure and improve cardiovascular health. Mushrooms also have anti-inflammatory properties and can boost the immune system by providing high amounts of selenium, vitamin D, and vitamin B6. The choline in mushrooms can help with muscle movement, learning, memory, and maintaining cellular membrane structure.
It is important to note that the nutritional profiles of mushrooms can vary between different types. For example, white mushrooms have slightly more calcium, while shiitake mushrooms are higher in fiber. Dried mushrooms tend to have more calories and nutrients than raw varieties due to their concentrated form. Canned mushrooms may also be higher in calories and sodium due to additives.

One cup of mushrooms (70g) provides only 15 calories, along with 2.2g of protein, 2.3g of carbohydrates, and 0.2g of fat. Most edible mushrooms contain important vitamins and minerals such as vitamin C, vitamin B6, magnesium, phosphorus, potassium, copper, folate, and zinc. They are also a good source of fiber, particularly the soluble fiber beta-glucan, and have a low glycemic index, making them a suitable option for those concerned about blood glucose levels.
Mushrooms are also heart-healthy and may help lower blood pressure due to their potassium content. They are a rich source of antioxidants, including glutathione and ergothioneine, which fight oxidative stress and inflammation, contributing to anti-aging and the prevention of chronic diseases. Additionally, mushrooms contain selenium, vitamin D, and vitamin B6, which support a healthy immune system by preventing cell damage, aiding in cell growth, and forming red blood cells.
Research suggests that consuming mushrooms may reduce the risk of cognitive impairment and protect against neurodegenerative diseases such as Alzheimer's and Parkinson's. They are also linked to a lower risk of cancer, with one review showing that eating just 18 grams of mushrooms daily may decrease cancer risk by up to 45%.
Mushrooms are versatile and can be easily incorporated into various dishes, adding a savory flavor without the need for added salt or fat. They are an excellent substitute for red meat, helping to minimize cholesterol, calories, and fat in the diet.

Risks of consuming raw mushrooms
While some mushrooms can be eaten raw, others pose potential health risks. Consuming raw mushrooms carries the risk of ingesting parasites, bacteria, viruses, and other contaminants that may be present on their surface. Cooking mushrooms can reduce these risks by eliminating harmful microorganisms and breaking down tough cell structures, making nutrients more accessible for absorption.
Some mushroom varieties, such as morels and shiitake, should always be cooked before consumption. Morels, for instance, contain natural toxins like helvellic acid and hydrazine, which are destroyed during cooking. Eating raw or undercooked morels can lead to food poisoning symptoms, including nausea, vomiting, and abdominal pain. Similarly, raw shiitake mushrooms can cause "shiitake dermatitis," a skin reaction characterized by a red, itchy rash.
Button mushrooms, a commonly consumed variety, contain agaritine, a compound suspected to be carcinogenic in high doses. Cooking significantly reduces the level of agaritine, making it safer to consume. Honey mushrooms also require thorough cooking to break down their mild toxins and eliminate harmful bacteria, making them unsafe for raw consumption.
Consuming raw wild mushrooms is particularly risky due to the potential presence of toxins or poisonous compounds. Many wild mushrooms are difficult to identify, and consuming the wrong variety can lead to severe poisoning, allergic reactions, and other health issues. It is always recommended to have expert knowledge or consult a mycologist before consuming wild mushrooms.
While some mushrooms can be safely consumed raw, cooking is generally recommended to enhance their flavour, improve digestibility, and reduce the risk of bacterial contamination and potential toxic compounds. However, if one chooses to consume raw mushrooms, it is important to follow safety tips such as thoroughly washing and drying the mushrooms, slicing them thinly, and combining them with vitamin C-rich foods to improve mineral absorption.
