Shiitake mushrooms are a type of fungus that grows on wood and is known for its pleasant aroma and rich nutritional value. It is considered superior to other mushrooms such as straw mushrooms, oyster mushrooms, and white button mushrooms, earning it the reputation of "Queen of Fungi" and "King of Mountain Delicacies". Shiitake mushrooms are a common ingredient in daily life and can be found in almost every kitchen. So, what are the benefits and drawbacks of eating shiitake mushrooms?
The Benefits of Eating Shiitake Mushrooms
Anti-aging Properties
Shiitake mushrooms contain a water extract that has a clearing effect on hydrogen peroxide, helping to eliminate it from the body. By removing free radicals and peroxides from the body, shiitake mushrooms can slow down the aging process.
Blood Pressure and Cholesterol Reduction
Shiitake mushrooms contain substances such as purines, choline, tyrosine, oxidase, and some nucleic acids, which can help lower blood pressure, reduce cholesterol, and lower blood lipid levels. They can also effectively prevent diseases such as arteriosclerosis and cirrhosis.
Amino Acid Supplementation
Shiitake mushrooms contain over 30 enzymes and 18 amino acids, including all 7 essential amino acids for the human body. Regular consumption of shiitake mushrooms can supplement the body with amino acids, enhance the body's resistance, and serve as the preferred food for correcting enzyme deficiencies and amino acid supplementation.
Anti-cancer and Tumor Prevention
The caps of shiitake mushrooms contain double-stranded ribonucleic acid, which, when ingested, can produce interferons with anti-cancer effects. Additionally, the polysaccharides in shiitake mushrooms can enhance the vitality of helper T cells, improve the body's humoral immune function, and reduce the ability of methylcholanthrene to induce tumors.
The Drawbacks of Eating Shiitake Mushrooms
Shiitake mushrooms contain a significant amount of dietary fiber, with 7% crude fiber in the edible portion per 100 grams. While this fiber can promote intestinal peristalsis and be beneficial for constipation and indigestion, it can also burden the gastrointestinal system and cause discomfort if consumed in large amounts or by individuals with weak digestive systems, as dietary fiber is difficult to digest.
On the other hand, shiitake mushrooms have a cooling nature and excessive consumption may lead to diarrhea. They are considered "windy" foods and may exacerbate existing health conditions, such as causing itching in individuals with skin problems. Therefore, it is advisable for such individuals to consume shiitake mushrooms in moderation.
