Help Boost Your Immunity With Shiitake Mushrooms

Shiitake mushrooms (Lentinus edodes) are one of the most commonly consumed mushrooms in the world, accounting for 17 percent of global mushroom consumption. Shiitakes deliver various health benefits, including an immunity boost when regularly consumed. In a 2011 study, participants who consumed shiitake mushrooms for four weeks were found to demonstrate improvements in their gamma delta T-cells and inflammatory proteins, which not only boosted their immune system, but also lessened their risk of inflammation.

A 2015 study also found that they help improve cell production and increase secretory immunoglobulin A (sIgA) production, which may lead to a better and more stable gut immunity. Shiitake mushrooms may also help improve your immune system and quality of life as you undergo chemotherapy.

Additionally, extracts of these fungi contain carbohydrates, protein, phenolic compounds and lignin digest that aid in numerous physiological activities. They were found to exhibit antioxidant activity that may help fight against various human diseases and alleviate paracetamol-induced liver damage. Some of the nutrients found in shiitake mushrooms are: Protein, Fiber, Calcium, Magnesium, Potassium, Niacin, Folate and Vitamin D.

When buying mushrooms, choose those that have been organically grown without pesticides, as they absorb and concentrate whatever they grow in, for better or worse. Mushrooms are known to concentrate heavy metals and other pollutants, so organic, pesticide-free growing conditions are important.

If your area's weather conditions permit, you may also grow your own mushrooms to be sure of their safety and freshness. If you keep them as a staple, dried shiitakes may also be an alternative to fresh mushrooms, which may give the soup a deeper flavor. Soak them in hot or boiling water, wait for at least 20 minutes and then gently squeeze out the excess water.

Whether store-bought or harvested from your garden, unused mushrooms must be placed inside a loosely closed paper bag and refrigerated as soon as possible. Also, remember that they will dry out and lose weight when stored for a long time, so it's best to consume them when they're fresh.
