I. What Are Edible Fungi?
Edible fungi refer to higher fungi with large fruiting bodies; common terms like "mushrooms," "fungi," and "xun (mushrooms)" all fall into this category. Globally, there are approximately 10,000 known species of fleshy edible fungi, among which over 3,000 are non-toxic and edible. They thrive in diverse ecosystems such as forests and grasslands.
II. Three Core Applications of Edible Fungi
- Edible Type: Includes common varieties like shiitake mushrooms, oyster mushrooms, enoki mushrooms, wood ear mushrooms, and tremella. These are widely used in daily cooking for their savory flavor and rich nutrition, making them popular ingredients.
- Medicinal Type: Represented by species such as Reishi, Poria cocos, and Polyporus umbellatus. Primarily used in the pharmaceutical field, they offer benefits like regulating immune function, protecting the liver, and aiding blood sugar reduction.
- Food & Medicine Type: Encompasses ingredients like Hericium erinaceus and Cordyceps sinensis. These can be used in culinary preparations while also providing notable health benefits, achieving the dual effect of dietary nourishment and wellness.
III. The "Health Code" in Edible Fungi: Efficacy of Core Components
- Fungal Polysaccharides: Unlike common starches and celluloses, these have a unique structure. They enhance immunity, scavenge free radicals, resist radiation, protect the liver and bone marrow, and support the body's protein synthesis.
- Adenosine: Prevents excessive platelet aggregation, reduces thrombus formation, improves blood circulation. It also helps regulate blood sugar, protect internal organs, boost oxygen-carrying capacity of hemoglobin, alleviate hypoxia-related discomfort in the heart and brain.
- Triterpenoids: Possess analgesic and sedative effects, reduce histamine release, protect the liver, and inhibit tumor cell growth.
- Fungal Cellulose: Lowers blood cholesterol, prevents atherosclerosis, and provides auxiliary improvement for constipation, diabetes, hypertension, and cerebral thrombosis.
- Armillaria Mellea-Related Components: Contain multiple active substances with more pronounced sedative effects than adenosine. They reduce blood coagulability, promote lipid dissolution, improve blood circulation and oxygen supply; their polysaccharides also enhance immunity.
- Shiitake Adenine: Helps lower cholesterol, prevent cirrhosis, and provides auxiliary therapeutic effects for hypertension, coronary heart disease, and diabetes. It also inhibits vascular sclerosis and aids in improving nephritis and proteinuria.
- Flavonoids: Alleviate myocardial ischemia, prevent arrhythmia, improve blood flow in coronary and cerebral arteries, increase cerebral blood flow, reduce cerebrovascular resistance. They also lower triglycerides, cholesterol, and blood viscosity, regulate blood sugar, scavenge free radicals, enhance immunity, and exert anti-cancer and antibacterial effects.
- Oleanolic Acid & Taurine: Strengthen immune system function, support the health of immune glands (e.g., thymus, spleen), reduce allergic reactions, and delay bodily aging.
IV. Core Value of Edible Fungi
With in-depth research, the value of edible fungi continues to be uncovered. Beyond being high-quality daily ingredients, they are hailed as "the health food of the 21st century," enriching dietary structures and supporting physical wellness. Currently, scientists have developed multiple new drugs from edible and medicinal fungi, with fungal polysaccharides and other components showing particularly promising development prospects.
