Yeast powder, also called yeast, is a single-celled fungus. It is also an edible nutrient with high nutritional value. Yeast also contains a variety of vitamins, minerals and enzymes, and is also rich in protein. In nutrition, it is even called "inexhaustible source of nutrition".
Yeast is an invisible microorganism and a natural starter, which is called "inexhaustible source of nutrition". It is nutritious and contains many vitamins and minerals. Therefore, using yeast to make steamed bread and steamed buns can increase the nutrition by 3-4 times, and protein will increase it by nearly 2 times. This is why eating steamed bread and yeast steamed bread for breakfast every day is not only harmless to human body, but also beneficial.

Old dough is a natural yeast starter, that is, it contains active bacteria, which are mixed with flour, and then the active bacteria grow rapidly in all dough through fermentation at a certain temperature, and then they swell. Steamed buns and steamed buns fermented with old noodles are really delicious! However, after the dough is fermented, it needs to be put with alkaline water, and it will not work without a lot. It is a very test of dough technology, and most people can't do it now.
Southerners may come into contact with fewer steamed buns, especially steamed buns, and most people don't eat steamed buns at ordinary times. However, because the north is rich in wheat, steamed bread is the staple food on the table. What's more, steamed bread is used for three meals a day. Steamed buns are also a common pastry with stuffing in the north, both sweet and salty, which can often be seen and sold in streets and alleys. Generally speaking, there are only three methods for people to make dough: dough fermentation, yeast fermentation and leavening agent (baking powder) fermentation. Among them, dough fermentation is now used by relatively few people, because the flora in dough is relatively complex, so the progress of fermentation is relatively difficult to control, and it is very easy to produce strong sour taste, which needs alkaline substances to neutralize. Then the remaining common are actually yeast fermentation and leavening agent fermentation. Compared with them, yeast is definitely better in nutrition and safety. Some people worry that they have no time in the morning, so they cook at home and often buy a steamed bread or steamed bread outside. It is more convenient and quick to buy outside, but the things sold outside are not as clean and hygienic as those sold inside. It is ok to eat breakfast out occasionally, but don't eat out often, because steamed bread or steamed buns outside need more yeast powder, because it will make them fluffy and have good color, smell and taste. But what you do at home is different, so you must allocate it in proportion. It is no problem to eat steamed bread and yeast dough steamed bread for breakfast every day, but from the nutritional point of view, the nutritional intake is too monotonous. It mainly contains carbohydrates and starch, and starch intake is converted into polysaccharides. And the heat is twice that of rice. There is also a small amount of plant protein, which is not as good as protein with eggs, milk and meat.
