Seven reasons to consume mushrooms regularly

Edible mushrooms have been treasured as not only as culinary delicacies, but also medicine since ancient times. Warriors in ancient Greece took mushrooms to gain strength for battle; to the Romans, the mushrooms were the “Food of the Gods”.  Similarly, in ancient China, mushrooms were considered the “elixir of life” [1]. Once considered to be rare and precious, many types of edible mushrooms are widely grown commercially today, making them readily available for everyone to enjoy.

A variety of commercially cultivated mushrooms are now available on the market.

Here are seven great reasons that we should all eat mushrooms regularly:

#1 Flavourful and delicious

Double mushrooms with vegetables, a signature Chinese dish.

Mushrooms are tasty and full of flavours. Mushrooms contain a wide variety of umami (or savoury) taste compounds [2]. The interactions of these umami compounds on taste buds create longer-lasting taste sensations, making food taste delicious. For example, in Chinese cuisine, fresh mushrooms that contain naturally occurring glutamate, often are combined with dried, rehydrated mushrooms that contain naturally occurring guanylate, to create the signature double mushroom dish (扒双菇).  The combination of glutamate and guanylate complement and enhance the flavours of the dish.

Mushrooms are so tasty that it is widely used as a natural flavour enhancer in many culinary practices, with extracts of mushrooms made into sauces and gravy to complement and enrich every dish. Most notably in Chinese vegetarian cooking, extracts of dry shiitake mushrooms are used as a replacement for savoury oyster sauce for everyday cooking. Mushroom extracts in cubes or powder forms are also used in place of mono sodium glutamate (MSG) as healthier substitutes.

#2 An excellent source of essential nutrients

Common edible mushrooms include button, shiitake, enoki, oyster, and portabella. All these mushrooms are high in protein and several under consumed nutrients such as dietary fibres, potassium, vitamin D, and calcium [3]. Mushrooms are also a good source of niacin, riboflavin, pantothenic acid, selenium, and copper. Consistent consumption of mushrooms over time contributes to a nutritious diet [3].

Most interestingly, mushrooms are unique compared to other plants as they can generate vitamin D when exposed to sunlight, converting vitamin D precursor ergosterol to vitamin D2 (ergocalciferol). To increase the vitamin D in mushrooms for more than 100% of its original content, simply by exposing them to sunlight for as little as 15 minutes on a clear or partly cloudy day between 9:30 AM and 3:30 PM [4]. With vitamin D deficiency linked to the risk of many diseases, including osteoporosis, arthritis, diabetes, cancer, cardiovascular disease, etc. [5] Consuming mushrooms regularly can help to alleviate the risk of vitamin D deficiency.

Exposure to sun light increases vitamin D content of mushrooms.

#3 Low in calories, fat, and sodium

Modern dietary pattern loaded with processed foods high in calories, saturated fat, and sodium has been recognized as the primary contributing factor of obesity, cardiovascular disease, and diabetes [6]. Mushrooms are naturally low in calories, fat, and sodium. To control obesity, mushrooms have been readily used as a substitute for meat to reduce the energy density of the diet. In a randomized control trial with 73 obese adults, it was found that participants who replaced meat with mushrooms were taking less calories and fats, losing more weight and total body fats, while having lower blood pressure, after one year, compared to the control group [7]. Notwithstanding, the richness of mushroom flavour also enhances the taste of food, helping to reduce the use of salt. In one trial, researchers found that substituting 80% of the meat in a traditional taco with mushrooms can reduce the sodium content by 25%, creating a healthier and tastier version of taco [8]

#4 Pack with Antioxidants

Constant exposure to oxidative stress due to imbalanced metabolism and excessive reactive oxygen species can damage health and accelerate aging [9]. The body requires a host of antioxidants from food to defend against oxidative stress. Edible mushrooms, both wild and cultivated, contain bioactive compounds, such as polyphenols, polysaccharides, vitamins, carotenoids and minerals that have significant antioxidant properties [8]. For this reason, in traditional Chinese medicine, edible mushrooms, especially Ling Zhi (Ganoderma lucidum) and Cordyceps (Cordyceps sinensis), has been used in anti-aging formula to refresh the body and promotes longevity [10]. However, such properties are not only restricted to expensive and exotic mushrooms. In a laboratory experiment, fruit flies fed with antioxidants from oyster mushrooms (Pleurotus spp.) lived longer than those did not [10].

Oyster mushrooms are packed with loads of antioxidants.

#5 A natural anti-inflammatory food

Mushrooms are also known to have strong anti-inflammatory properties. Various types of mushrooms have been used in folk medicine to reduce pain and inflammation. Modern medicine also started to consider mushrooms as a potent natural source of anti-Inflammatory agents to reduce the reliance on nonsteroidal anti-inflammatory drugs [11]. For example, the blood inflammatory markers of patients with inflammatory bowel diseases, ulcerative colitis, and Crohn’s disease were shown to significantly decrease after taking a mushroom extract mixture of almond mushroom, bearded tooth mushroom, and Maitake for 12 days [11].

#6 Anti-cancer properties

The anti-cancer and immunomodulating properties of many medicinal mushrooms have attracted immense interest in research and clinical application of cancer treatment. Mushrooms are known to complement chemotherapy and radiation therapy by countering the side-effects of cancer, such as nausea, bone marrow suppression, anaemia, and lowered immune resistance [12]. The polysaccharide, β-glucan, from mushrooms is the best known and most potent mushroom-derived substances with anti-tumour and immunomodulating properties. Current research findings also suggest that some mushrooms can work in synergy in combination with anti-cancer drugs for effective treatment of drug-resistant cancers [12].

Ling Zhi or Reishi mushroom is used as a complementary medicine for cancer treatment

Many of the commercially available edible mushrooms, such as button, almond, oyster, shiitake, and Maitake also have similar contents of effective anticancer compounds, hence regular consumption of mushrooms may also have cancer prevention effects [13]. One study in Korea, which examined 358 breast cancer patients and 360 cancer-free controls, found that high consumption of mushrooms might be related to lower risks of breast cancers, especially among premenopausal women [2]. Another study conducted in Guangzhou, China, also found that intake of mushrooms, particularly the white button mushroom, is associated with the lower incidence of ovarian cancer. These studies demonstrated the cancer preventive benefits of consuming mushrooms regularly.

#7 A sustainable food choice

Beside health and taste, eating more mushrooms is also good for the environment. Commercial mushrooms production is consistent with a sustainable food supply. Mushroom production requires a small land size that can be easily managed by a local family owned business.  Mushroom farms recycle by-products from other agricultural or horticultural sectors that previously posed waste management challenges. The substrate material that mushrooms grown on can also be recycled as a soil amendment. Mushrooms are grown indoors with little energy and water needs [3]. The sustainability of mushroom production has created an important food source for current and future generations to enjoy.
