In addition, shiitake mushrooms are rich in vitamin D and selenium, which have positive effects on bone health and anti-aging. The following will be explained in detail in terms of immune regulation, cardiovascular protection, antioxidant, etc.

Enhance immunity and anti-viral effect

in mushroomspolysaccharides(such as lentinan) can activate macrophages and T lymphocytes and enhance human immune function. Research shows that long-term consumption of shiitake mushrooms can reduce the frequency of colds and has a certain inhibitory effect on influenza viruses (quoted from a 2020 study in "Chinese Edible Fungi"). Japanese scholar Dr. Tetsuro Ikekawa also proposed that lentinan has potential effects in adjuvant anti-cancer treatment. Related products on the market such as"Corrected Lentinin Polysaccharide Tablets"The main selling point is immune regulation.

Cardiovascular protection and blood lipid regulation

Data from the Chinese Center for Disease Control and Prevention in 2018 showed that daily intake of 50 grams of fresh mushrooms can reduce low-density lipoprotein (LDL) by 10%-15%. Some companies such as"Infinitus"The launched mushroom extract capsules are designed to meet the needs of blood lipid regulation.
