Mushrooms should be dried before eating.

According to the results of a recent study in the United States, juicy mushrooms are a rich source of vitamin D in the diet, and eating mushrooms scientifically is good for bone health.

Mushrooms are rich in protein, with a digestibility of 70% to 90%, which is known as "plant meat". The content of nutrients is different in different parts of mushrooms. Generally speaking, the cap is more nutritious than the stalk, and the most suitable for eating is the fresh, tender mushroom fruiting body. Mushrooms are not only nutritious, delicious and rich in lysine, but also rich in mineral elements, such as selenium, which can enhance the activity of glutathione peroxidase in blood and prevent peroxides from damaging the body. improve the body's immunity. Mushroom contains a large number of plant fiber, with the role of preventing constipation, promoting detoxification, preventing diabetes and colorectal cancer, reducing cholesterol content, and it belongs to low-calorie food, can prevent weight gain, it is also a better weight loss beauty food.

The content of vitamin D in Lentinus edodes is 20 times higher than that of soybean and 8 times higher than that of kelp. Vitamin D can help the body absorb calcium, which is good for bone health. There are few natural sources of vitamin D, in which milk and some fish contain vitamin D, and ultraviolet rays in sunlight can also promote the synthesis of vitamin D in human skin, so mushrooms are undoubtedly one of the important sources of vitamin D in natural foods.

A new study by FDA in the United States found that ultraviolet radiation on growing or freshly picked fresh mushrooms can cause mushrooms to produce large amounts of vitamin D, which was reported at the Food and Drug Administration Science Forum in the United States. The researchers exposed fresh white round mushrooms picked by ultraviolet light for five minutes to produce large amounts of vitamin D, which is 8.69 times what the human body needs every day. When the growing mushrooms were irradiated with ultraviolet light for 3 hours, the content of vitamin D increased significantly. These experiments confirm that mushrooms can increase vitamin D after exposure to the sun. In fact, the reason why mushrooms have such a magical effect is that they contain the precursor of vitamin D, masterol, which is converted into vitamin D when exposed to sunlight.

The research progress suggests that mushrooms are very beneficial to all people, especially teenagers, elderly women and other people who need calcium supplements, and in order to make them more nutritious and maximize their nutritional value, we should first choose fresh mushrooms. and it's best to put mushrooms in the sun for a period of time before eating. When people supplement calcium, increasing the intake of vitamin D can promote the absorption and utilization of calcium, so the large amount of vitamin D brought by mushrooms is undoubtedly a good choice.
