Oyster mushrooms: The nutritional powerhouse hidden in Canadian forests

Oyster mushrooms are cultivated mushrooms that originated from China. We usually purchase them in the store, but remember that they can also be found in the forest. Unlike other forest mushrooms, oyster mushrooms are characterized by high nutritional value. See why they are worth including in your diet.

Although oyster mushrooms in Canada are mainly associated with cultivation, these mushrooms are commonly found in forests. However, they are not usually collected, which is a pity because they are one of the few mushrooms that start growing in the fall and are present until spring. Additionally, they grow in clusters so that you can collect several kilograms in one place.

Oyster mushrooms, edible cultivated mushrooms from China, are gaining popularity in Canada. They are distinguished by their high content of easily digestible protein. They contain all the B vitamins and vitamins D and C (100 grams cover 15 percent of the daily requirement for vitamin C for an adult). Unlike forest mushrooms, oyster mushrooms are rich in mineral salts such as calcium, iron, magnesium, phosphorus, potassium, selenium, sodium, and zinc. Due to their low carbohydrate content, they are low in calories (about 35-50 kcal per 100 grams of fresh mass). Another advantage is their low-fat content while high in unsaturated fatty acids such as alpha-linolenic acid.

Regular consumption of oyster mushrooms lowers cholesterol and blood sugar levels and improves blood vessel conditions in people with arteriosclerosis. These mushrooms also contain ergothioneine, an antioxidant that protects cells from damage and aging, and it does not lose its properties during cooking.

Scientific research shows that pleuran, an active substance found in oyster mushroom extract, can reduce tumors. Japanese scientists have proven the properties of pleuran, while researchers from Slovakia have identified beta-glucan in oyster mushrooms, which strengthens the immune system and fights certain cancers.

Due to their delicacy, oyster mushrooms should be washed carefully and briefly to prevent them from absorbing water. The best parts for cooking are the brittle caps. Cooked oyster mushrooms can be added to salads and soups and also used as stuffing for pancakes or dumplings.

Oyster mushrooms are excellent for omelettes and as a vegetarian alternative to classic meat dishes, such as pork chops. They can also be frozen, dried, and pickled. Grilled, they pair perfectly with cheese, creating tasty toast.
