What's New and Beneficial about Shiitake Mushrooms

  • New research has shown that a relatively small daily amount of dried shiitake mushroom (5 grams of dried mushroom, which is the equivalent of 1-ounce fresh mushroom or less than one large shiitake mushroom) can provide measurable anti-inflammatory benefits. This finding is great news for anyone who is interested in bringing small amounts of shiitake mushrooms into his or her diet, without necessarily making it any sort of dietary focus. Consumption of these small amounts of shiitake mushroom by 50 study participants lowered blood levels of the inflammatory messaging molecule MIP-1alpha (macrophage inflammatory protein 1alpha) and increased blood levels of anti-inflammatory molecules including interleukins 4, 10, and 1alpha (IL-4, IL-10, and IL-1a). This study outcome is not surprising since shiitake mushrooms have an extensive track record as an anti-inflammatory food. But it is great to see these benefits coming from dietary intake of shiitake mushrooms in a whole food form, and more importantly, in a very "do-able" intake amount. Just how easy would it be to consume this amount of shiitake mushrooms? In our 7-Day Menu we include 5 fresh shiitake mushrooms in our Day 4 dinner alone. All by itself, this amount comes close to matching the shiitake mushroom intake that provided participants with these anti-inflammatory benefits.
  • Researchers are getting closer and closer to understanding the biotin content of shiitake mushrooms, and this advance in understanding should eventually pay real dividends for our health. At WHFoods, we don't provide any data values for biotin in shiitake mushrooms (or in crimini mushrooms) due to the scientific difficulties in measuring biotin levels. However, we are confident that shiitake and most other commonly eaten mushrooms provide very valuable amounts of biotin! So we are excited to see new studies about proteins in shiitake mushrooms called lentiavidins. You might recognize the "avidins" part of this name from research on egg whites. Avidins are egg-white proteins that can bind together with biotin. In the case of shiitake, researchers have added the designation "lenti"—from the shiitake genus Lentinula—to come up with the new protein name, "lentiavidins." Thanks to recent research, we now know that lentiavidins are unique proteins in shiitake mushrooms that can bind together with biotin. What we don't know is how these lentiavidins affect the retention of biotin in shiitake or the bioavailability of biotin from shiitake. But researchers are getting closer to answers here, and we view this research as providing additional evidence about the role of shiitake mushrooms are likely to play in providing us with important amounts of this B-complex vitamin.
  • At WHFoods, shiitake mushrooms are our 4th best source of copper. (Our top three sources for this antioxidant mineral are sesame seeds, cashew nuts, and soybeans.) Researchers now know that a key enzyme found in shiitake mushrooms—called laccase—requires four atoms of copper to function properly. As a result of its laccase enzyme content, shiitake provides us with 650 micrograms of copper (0.65 milligrams) in a serving size of ½ cup cooked. Since our WHFoods recommended daily intake level for copper is 900 micrograms (0.9 milligrams), about 72% of daily copper intake can be obtained from a single serving of shiitake mushrooms.
  • We are seeing an increasing level of research interest in one unique alkaloid found in shiitake mushrooms, namely, eritadenine. When compared to commonly eaten mushrooms like crimini and reishi, shiitake mushrooms appears to contain significantly higher amounts of eritadenine. Much of the interest in this phytonutrient has been focused on its ability to inhibit activity of an enzyme called angiotensin-converting enzyme (ACE). Because ACE activity results in a constricting of our blood vessels, inhibition of ACE can help prevent unwanted blood vessel constriction. By preventing unwanted constriction, our blood vessels can keep a wider diameter and this wider diameter allows the pressure on our blood to stay within a normal range. In short: what we are looking at here is a unique nutrient in shiitake mushrooms that appears to increase our chances for better blood pressure regulation.
  • A variety of different studies on the health benefits of shiitake mushrooms have converged on a special group of carbohydrate-related molecules called glucans. Glucans are polysaccharides (structures comprised of linked sugars) that are found in many different foods. However, shiitake mushrooms are unusual in containing not only a large amount of total glucans but also a large amount of one specific glucan called beta-glucan. Because these glucans cannot be broken down by enzymes in our digestive tract, they pass undigested all the way through to our large intestine where they help support growth of desirable bacteria in our digestive tract. This result earns shiitake mushrooms the right to be called a health-supportive food. But perhaps more importantly, beta-glucans also provide support for a wide variety of body systems, including our immune system, antioxidant system, and our endocrine system. Because beta-glucans can bind onto certain receptors on our immune cells, they can help support immune system function. These polysaccharides can also function as antioxidants and have been shown to have free radical scavenging activity. In addition, beta-glucan intake has been linked to better regulation of our blood sugar and insulin levels. What we are left with here is a category of nutrient intake—polysaccharides—that we don't usually associate with such a wide range of potential health benefits. But research on shiitake mushrooms is convincing us to pay more attention to this carb-related group in shiitake and other mushrooms.

WHFoods Recommendations

At WHFoods, we include mushrooms as vegetable subgroup among our 38 WHFoods vegetables because we think about this food in a very common sense way. Most people have become used to finding shiitake mushroom in the produce section of the grocery, surrounded by many other types of vegetables. However, we realize that from a scientific perspective, mushrooms are not considered to be either plants or animals but have their own special kingdom of life called the fungi kingdom. For this reason, we understand why some people might feel like it is technically incorrect to include shiitake mushrooms among a vegetable group where all of the other vegetables are classified as plants. But in terms of the grocery store and the kitchen, we think it makes sense to think about shiitake and other mushrooms as part of the vegetable group.

Our WHFoods optimal intake level for vegetables is 10 total servings per day. Many different vegetable subgroup combinations can be used to reach this 10-serving total. Included are cruciferous vegetables, allium vegetables like garlic and onions, leguminous vegetables like green beans and green peas, and of course mushrooms—including shiitake mushrooms. In our 7-Day Menu, we include both shiitake and crimini mushrooms in our weekly dinner recipes, and for the entire week, we include five whole shiitake mushrooms. While we do not specify a minimum level of weekly intake for either shiitake or crimini mushrooms in our Vegetable Advisor (or anywhere on our website), we recommend inclusion of mushrooms in your total weekly vegetable servings based on their unique nutrient composition and equally unique health benefits.

Health Benefits

Unique Nutrient Benefits from Shiitake Mushrooms

When thinking about the health benefits of shiitake mushrooms, it's worth remembering that this food does not belong either to the plant family or to the animal family but to its own separate group of life forms known as fungi. (From a science perspective, shiitake mushrooms are classified as "macrofungi" since they are large compared with other microorganisms and can easily be seen without the help of a microscope.) In some ways, fungi like shiitake mushrooms are actually closer to animals than to plants because they can synthesize glycogen (a storable form of starch) in the same way as animals. This feature of fungi often provides them with many unique nutrients in the carbohydrate category. In addition, because shiitake often make their home on hardwood trees, they are have special enzyme systems for breaking down wood components, and these systems also provide them with unique nutrient features. The chart below summarizes some of the better-studied unique nutrients in shiitake.

(milligrams per 100 grams of food)

carvacrolmonoterpenoid-derived phenols
copalic acidditerpenoids
ergothioneineamino acid derivatives
eritadeninealkaloids
lentiavidinsproteins
lentinanspecific member of the beta-glucan polysaccharides

Among the nutrients listed above, lentinan and its fellow beta-glucans have received special research attention. These unique polysaccharide nutrients have been shown to have antioxidant and anti-inflammatory properties, within the digestive tract, within the bloodstream, and in whole body metabolism involving a variety of different body systems. While we will be addressing more specifics about this unique list of nutrients and their health benefits in the paragraphs below, we wanted to make sure that this particular collection of nutrients was seen for what it is: a unique and remarkable group of substances that provides many of the core health benefits from shiitake.

Antioxidant and Anti-Inflammatory Benefits from Shiitake Mushrooms

If we look only at conventional nutrients found in shiitake mushrooms, we can see impressive antioxidant benefits. As mentioned earlier, shiitake are our 4th best source of the antioxidant mineral copper at WHFoods. They are also our 4th best source of another antioxidant mineral—zinc. And this list of antioxidant minerals does not stop with zinc. Shiitake are also our 7th best source of the antioxidant mineral selenium. While you could get a higher-ranked source of selenium by choosing many of our fish, these foods drop down below shiitake mushrooms on our list of high-ranked zinc sources. Similarly, you could get a higher-ranked source of zinc by choosing beef from our WHFoods, but beef is far below shiitake mushrooms on our list of copper sources. So it makes sense to think about shiitake mushrooms as a quite unusual source of multiple antioxidant minerals.

It's the more unusual nutrients in shiitake mushrooms, however, that provide this food with its antioxidant "claim to fame." For example, multiple studies have linked broad antioxidant and free-radical scavenging activity with intake of shiitake mushrooms due to their high beta-glucan content. Also interesting in this context are studies that have found a greater degree of antioxidant activity to be associated with polysaccharides from shiitake mushrooms that contain disproportionally high amounts of the sugars rhamnose and mannose. Alongside of their glucan content, shiitake mushrooms are known to provide us with phenolic antioxidants (like ferulic and capolic acid), and terpene-related antoxidants like carvacrol.

On the anti-inflammatory front, a growing number of studies have shown reduction in inflammation-related events following intake of shiitake mushrooms. As mentioned earlier in this profile, consumption of shiitake mushrooms in one recent study was determined not only to lower blood levels of the inflammatory messaging molecule MIP-1alpha (macrophage inflammatory protein 1alpha), but also to raise blood levels of anti-inflammatory molecules including interleukin-4 and -10, and interleukin 1alpha (IL-4, IL-10, and IL-1a). Additionally, many of the phenolic acids provided by shiitake mushrooms have been determined to provide anti-inflammatory benefits.

Other Potential Health Benefits from Shiitake Mushrooms

In many areas of decreased disease risk—including risk of certain cancers, cardiovascular diseases, immune system problems, and type 2 diabetes—we have pieces of evidence (often from lab studies on cell cultures or from studies on mice or rats) about the likely role played by shiitake mushroom intake in helping to prevent chronic disease. However, most of these studies involve either purified components from shiitake mushrooms or shiitake mushroom extracts rather than dietary intake of these mushrooms in whole food form. For all of the reasons above, we have referred to research in the areas described below as demonstrating potential health benefits, and we look to future studies to confirm these benefits for people who enjoy eating shiitake mushrooms in food form in their diet.

Potential immune system benefits from shiitake mushrooms have been a focus in recent studies involving an immune-related messaging molecule called interleukin-23 (IL-23). IL-23 is one of the messaging molecules produced by the immune system's dendritic cells. A key role of our dendritic cells is to help process potentially allergenic or harmful substances and present them to other immune cells for neutralization. In animal studies, intake of shiitake mushroom extracts has been shown to increase IL-23 levels, and by increasing these levels, they also help to improve the recognition of potentially allergenic or harmful substances, particularly in the lower part of the digestive tract (colon). Researchers believe that this ability of shiitake mushrooms to improve gut immunity may also apply to humans who consume shiitake mushrooms in whole food form and ordinary amounts.

Two other substances in shiitake mushrooms that seem important to mention in this immune system context are conjugated linoleic acid (CLA) and ergothioneine, a sulfur-containing derivative of the amino acid histidine. Both of these substances have been shown to have immune-related properties and are regarded as providing immune support.

Numerous lab studies on cancer cells lines have shown the ability of shiitake mushroom extracts to inhibit tumor growth. Researchers have also linked the unique polysaccharide content of shiitake mushrooms to these tumor-inhibiting results. To date, potential benefits of shiitake mushrooms for reduced risk of colon cancer have been a primary area of interest, but we expect to see other types of cancer being closely investigated in this context as well.

An area of strong shiitake mushroom interest that partially overlaps with investigation of cancers involves the role of microorganisms in promotion of chronic inflammation and subsequent elevation of cancer risk. Unwanted overgrowth of certain microorganisms can cause chronic inflammation and infection; through these processes, they can increase cancer risk. Countering this type of risk are some of the unique sulfur compounds found in shiitake mushrooms, which have been shown to possess antiviral, antibacterial, and antifungal properties. These antimicrobial properties in shiitake mushrooms may turn out to play an important role in the cancer-preventing potential of this food.

As mentioned earlier in this profile, researchers know that eritadenine—a purine-based alkaloid in shiitake mushrooms—is able to block activity of an enzyme related to regulation of blood pressure known as ACE (angiotensin-converting enzyme). When ACE is fully active, our blood vessels become constricted, and this constriction gives our blood less space in which to flow; as a result of this, our blood pressure increases. By blocking ACE activity, the eritadenine in shiitake mushrooms helps achieve the opposite effect: blood vessel constriction is prevented, our blood vessels maintain a wider diameter providing for more space for our blood to pass through, and an increase in our blood pressure is prevented. Not surprisingly, many researchers conclude that shiitake mushrooms provide us with cardiovascular support through improved regulation of blood pressure.

Also important on this cardiovascular front are the unique sulfur compounds present in shiitake mushrooms. Shiitake mushrooms appear to have their own unique sulfur-metabolizing enzyme that falls into the category of enzymes known as the "cysteine desulfurases." These enzymes are responsible for taking the sulfur in cysteine amino acids and helping incorporate it into other metabolic activities. These unique sulfur-related metabolic activities in shiitake mushrooms have been linked to several different aspects of cardiovascular function, including the degree to which our platelet cells clump together (or "aggregate") in our blood stream. In general, studies on shiitake show a potential for better control of platelet aggregation when shiitake mushroom extracts are included in the diets of lab animals.

Improved regulation of blood sugar levels and insulin secretion has been a research finding in multiple animal studies involving consumption of shiitake mushroom extracts. While many components of shiitake mushrooms may contribute to these helpful effects, it should not be surprising that these mushrooms can be helpful for controlling our blood sugar. Shiitake mushrooms is a good source of fiber and provides us with 1.5 grams for only 51 calories. We also know that many shiitake mushroom polysaccharides do not get broken down in our upper digestive tract, so their simple sugars do not get released for absorption up into our bloodstream. Both of these factors point to a food that would be helpful in blood sugar regulation. However, it will take large-scale studies on human participants consuming shiitake mushrooms in their routine diet to determine whether intake of this food is a reliable way to lower our risk of type 2 diabetes or related health problems.

Description

As part of the kingdom of living things that we call fungi, shiitake mushrooms are neither plants nor animals but have their own separate category as a life form. Among the 100 foods that we profile on our website, only two are fungi (shiitake and crimini mushrooms). It is their membership in this unique group that gives shiitake mushrooms many of their unique nutrient and health benefits.

The part of shiitake mushrooms that we eat is actually the fruit of the fungus. The main body of the fungus consists of a fabric-like mass of thin white strands, and these strands are the part that colonizes dead fallen trees, tree stumps, and other decaying organic matter in forests and other habitats. Like all fungi, shiitake mushrooms use spores to reproduce. Because the defense systems in living trees can detect the presence of shiitake mushroom spores and prevent their growth, fungi like shiitake mushrooms need decaying trees or other forms of decaying matter in order to grow. This reliance on decaying matter for growth is what classifies them as a "saprophytic" mushroom along with many fellow mushrooms, including crimini, enokitake, maitake, oyster, paddy straw, portobello, and reishi.

The unique growing conditions for shiitake mushrooms have given rise to ongoing debate about commercial methods for producing shiitake mushrooms. In a natural setting, fallen hardwood trees (or their branches or stumps) provide the best growth spots for shiitake mushrooms due to the higher density of the wood in hardwood trees. Examples of hardwoods include oak, chestnut, hickory, eucalyptus, alder, ash, beech, and perhaps most famously, the Japanese Chinquapin (Castanopsis cuspidate), also called the "shii" tree and long-documented as the tree from which shiitake mushrooms received their name.

Not only do many commercial producers of organic shiitake mushrooms favor production using hardwood tree logs, but many lovers of shiitake mushroom find major differences in taste from log-grown shiitake versus shiitake grown under other conditions. Since shiitake mushrooms can grow on various types of decaying matter, faster and easier methods for large-scale shiitake cultivation have been developed by growers. Many of these methods use sawdust and a grain additive (for example, wheat bran) that can be mechanically processed and mechanically routed into a plastic bag. This sawdust-filled plastic bag can then be used in place of an intact hardwood log as the growth environment for shiitake. We have not seen detailed journal studies on the nutritional differences between log-grown and sawdust-grown shiitake mushrooms, and of course, many other variables besides tree versus sawdust would need to be evaluated in order to investigate nutritional differences. But we can say with confidence that shiitake mushrooms are no different than any of our other WHFoods in terms of their reliance on high-quality, natural growth conditions. Whether we are talking about pasture-raised chicken, grass-fed beef, organically grown vegetables, or traditionally fermented tofu, there are qualitative differences in the foods we enjoy that always point back to the quality of their growing conditions. And using this logic, we would expect future studies to show some nutritional advantages to log-grown shiitake. While not always the case, smaller, local producers of organic shiitake mushrooms are more likely to have used log-based growing conditions than very large-scale producers who export the mushrooms worldwide.

When purchased in dried form, a second important issue related to shiitake mushrooms is the method used for drying. Worldwide, hot air drying is the most common method used for drying fresh shiitake mushrooms. However, other methods for shiitake mushroom drying have also been developed, including vacuum drying, microwave drying, and microwave vacuum drying. We've seen one study showing improved retention of taste-related amino acids and sulfur compounds from microwave drying (when compared to these other commercial methods). The most longstanding method for drying shiitake mushrooms, of course, is sun drying. Like the lack of information on nutritional differences from log versus sawdust growing, there is a lack of research information on nutritional differences from sun drying versus other drying methods. It's worth pointing out, however, that in many regions of the world where shiitake mushrooms are grown commercially, sun drying would not be possible due to local climate. Also worth noting is the reliance of many large-scale sun-drying operations on additional equipment and/or construction of buildings designed to optimize the drying process. In these cases, it might be more accurate to use the term "solar assisted drying" or "solar-based drying" rather than the simple description of "sun dried."

In appearance, shiitake mushrooms have brown, slightly convex caps that range in diameter from about two to four inches. When young and freshly fruited, shiitake mushrooms tend to have darker colored tops which are rounder in shape. But as the fruit develops, it tends to lighten in shade and flatten out. The underside of shiitake mushrooms (called the gills) are mostly pale white in color.

The scientific name for shiitake is Lentinula edodes. You will also see the genus portion of this name—"Lentinula"—appearing as "Lentinus" since that designation was the first to be used historically. The family to which shiitake mushrooms belong is called the Marasmiaceae, and these mushrooms also belong to the Basidiomycota division of the Fungi Kingdom.

History

While we have documented evidence of shiitake cultivation as early as 1100 AD during the Sung Dynasty in China, cultivation of this mushroom may have begun long before this time. As a fungus native to East Asia, and particularly in the more tropical regions, it's not surprising to find it appearing as a popular food in many East Asian countries, including China, Japan, and Korea. It's also worth noting that shiitake mushroom has an equally long history of medicinal use in many of these same countries.

Today, China is by far the world's largest producer of shiitake mushrooms, supplying 80-90% of all those commercially sold. Many other countries produce smaller amounts of these mushrooms, including Korea, Japan, Brazil, and the United States. On a global basis, approximately 150,000 tons of shiitake mushrooms are produced each year.

Within the United States, crimini ("button") mushrooms are by far the most widely produced and widely consumed type of mushroom. When all types of mushrooms are taken into account, U.S. per capita consumption has increased from about 2.5 pounds per year in the 1970's to about 4 pounds per year today.

How to Select and Store

Shiitake mushrooms are available in many grocery stores throughout the country.

Look for mushrooms that are firm, plump and clean. Those that are wrinkled or have wet slimy spots should be avoided.

At WHFoods, we encourage the purchase of certified organically grown foods, and shiitake mushrooms are no exception. Repeated research studies on organic foods as a group show that your likelihood of exposure to contaminants such as pesticides and heavy metals can be greatly reduced through the purchased of certified organic foods, including shiitake mushrooms. In many cases, you may be able to find a local organic grower who sells shiitake mushroom but has not applied for formal organic certification either through the U.S. Department of Agriculture (USDA) or through a state agency. (Examples of states offering state-certified organic foods include California, New York, Oregon, Vermont, and Washington.) However, if you are shopping in a large supermarket, your most reliable source of organically grown shiitake mushrooms is very likely to be shiitake mushrooms that display the USDA organic logo.

The best way to store loose shiitake mushrooms is to keep them in the refrigerator in a loosely closed paper bag. They will keep fresh for about one week. Dried mushrooms should be stored in a tightly sealed container in either the refrigerator or freezer where they will stay fresh for six months to one year.

Here is some background on why we recommend refrigerating shiitake mushrooms. Whenever food is stored, four basic factors affect its nutrient composition: exposure to air, exposure to light, exposure to heat, and length of time in storage. Vitamin C, vitamin B6, and carotenoids are good examples of nutrients highly susceptible to heat, and for this reason, their loss from food is very likely to be slowed down through refrigeration.

Tips for Preparing and Cooking

Tips for Preparing Shiitake Mushrooms

Mushrooms are very porous, so if they are exposed to too much water they will quickly absorb it and become soggy. Therefore, the best way to clean mushrooms without sacrificing their texture and taste is to clean them using minimal, if any, water. To do this, simply wipe them with a slightly damp paper towel or kitchen cloth. You could also use a mushroom brush, available at most kitchenware stores.

If the fresh mushrooms become dried out because of being stored for too long, soak them in water for thirty minutes.

The Nutrient-Rich Way of Cooking Shiitake Mushrooms

We recommend Healthy Sautéeing shiitake mushrooms. We feel that this method also gives shiitake mushrooms maximum flavor.

Healthy SautéQuick Steaming—similar to Quick Boiling and Quick Steaming, our other recommended cooking methods—follows three basic cooking guidelines that are generally associated in food science research with improved nutrient retention. These three guidelines are: (1) minimal necessary heat exposure; (2) minimal necessary cooking duration; (3) minimal necessary food surface contact with cooking liquid.

Heat 3 TBS of broth over medium heat in a stainless steel skilled. When broth begins to steam add sliced mushrooms and Healthy Sauté for 7 minutes. It is best to stir constantly for the last 4 minutes of cooking. Toss with our Mediterranean Dressing and your favorite optional ingredients. For details see, Healthy Sautéed Shiitake Mushrooms.

How to Enjoy

A Few Quick Serving Ideas

  • Shiitake mushrooms are traditionally added to miso soup.
  • Healthy saute mushrooms with onions and garlic. Serve as a side dish or as a topping for chicken, beef, lamb or venison.
  • To give your vegetable stock an extra depth, add dried shiitake mushrooms.
  • For a quick and easy Asian pasta dish, healthy saute shiitake mushrooms with snap peas and tofu. Season to taste and serve over buckwheat soba noodles (or your favorite type of pasta).

Nutritional Profile

Unique nutrients in shiitake mushrooms include glucan polysaccharides (including beta-glucans like lentinan), terpenoid-related nutrients like copalic acid, amino acid derivatives like ergothioneine, and many other unique compounds. While shiitake mushrooms are an excellent source of the minerals copper and selenium, they also provide a very good amount of zinc, and we consider them to be unusual in this mineral combination. Shiitake mushrooms provides a rich combination of B vitamins, including excellent amounts of B2 and pantothenic acid, and good amounts of B3, B6, folate and choline. While we cannot provide a reliable quantity for the about of biotin in shiitake mushrooms, we are confident that this B vitamin is also present in these mushrooms. Rounding out the nutrient contributions of shiitake mushrooms are its good levels of manganese, vitamin D, and fiber.

Introduction to Food Rating System Chart

In order to better help you identify foods that feature a high concentration of nutrients for the calories they contain, we created a Food Rating System. This system allows us to highlight the foods that are especially rich in particular nutrients. The following chart shows the nutrients for which this food is either an excellent, very good, or good source (below the chart you will find a table that explains these qualifications). If a nutrient is not listed in the chart, it does not necessarily mean that the food doesn't contain it. It simply means that the nutrient is not provided in a sufficient amount or concentration to meet our rating criteria. (To view this food's in-depth nutritional profile that includes values for dozens of nutrients - not just the ones rated as excellent, very good, or good - please use the link below the chart.) To read this chart accurately, you'll need to glance up in the top left corner where you will find the name of the food and the serving size we used to calculate the food's nutrient composition. This serving size will tell you how much of the food you need to eat to obtain the amount of nutrients found in the chart. Now, returning to the chart itself, you can look next to the nutrient name in order to find the nutrient amount it offers, the percent Daily Value (DV%) that this amount represents, the nutrient density that we calculated for this food and nutrient, and the rating we established in our rating system. For most of our nutrient ratings, we adopted the government standards for food labeling that are found in the U.S. Food and Drug Administration's "Reference Values for Nutrition Labeling."
