Introduction: Nowadays, many families add yeast when making pastries, which makes the pastry fluffy and soft. In addition, yeast can produce food faster and is popular among many people.

The main function of yeast is to break down starch to produce carbon dioxide and glucose starch to support dough and expand it. However, some people believe that consuming too much yeast can be harmful to the body.

Some people even said that yeast Mantou should be eaten less because yeast has carcinogenic effect. Others said that regular consumption of yeast Mantou would lead to increased uric acid and induce gout. Is that really the case? Let's share it with everyone here today.

01

What is yeast powder?

Yeast powder mainly contains yeast for various purposes such as fermentation and seasoning. Eating yeast powder and yeast products in normal doses is not harmful to the body, but can also improve food taste and alleviate loss of appetite.

Yeast powder, as a fermenting agent and seasoning agent, reacts with substances such as water flour at appropriate temperatures to produce carbon dioxide. Eating food with added yeast powder will make it softer, taste better, and have no sour taste.

Yeast powder can be used to make bread, steamed buns, Mantou, etc. Flour contains iron, calcium, magnesium and other mineral ingredients. With the participation of yeast, the body will better absorb these nutrients.

In addition, for people who are prone to overeating, consuming foods containing yeast powder in moderation can effectively improve symptoms such as indigestion. However, yeast powder, like salt, sugar, and other seasonings, is not suitable for consuming in large quantities, which may affect the taste of the food and cause gastrointestinal discomfort.

Is long-term consumption of "yeast Mantou" good or bad for your health? Doctor says the answer

The rumor that yeast can cause cancer has been discussed by various netizens, and many people even blacklist yeast and dare not eat food related to yeast. However, is yeast really carcinogenic?

Yeast belongs to single cell anaerobic eukaryotic microorganism, which is a kind of biological filler. The use of yeast in dough can promote the formation of protein chain, absorb sugar in dough, produce carbon dioxide and alcohol, and play a role in fermentation.

The flour itself absorbs some oxygen during the mixing process, and yeast fermentation makes the dough more gluten. During this process, a large amount of volatile organic compounds are produced, which form a unique aroma for foods such as bread.

Can yeast cause cancer? The answer is no.

In addition, yeast powder itself contains rich protein, dietary fiber, vitamin B group, selenium, and chromium elements, so yeast powder itself will not cause harm to the body.

The harm of yeast powder is mainly indirectly reflected in added foods, such as steamed buns, bread, etc. If consumed in large quantities, it can cause blood sugar fluctuations and be harmful to obese and high blood sugar populations.

03

Will frequent consumption of yeast fermented Mantou lead to increased uric acid, which will lead to gout?

Long term intake of a high purine diet in the human body is a high-risk factor for high uric acid and gout. It is mainly divided into three categories in daily life: high purine diet, moderate purine diet, and low purine diet.

From the perspective of purine content alone, the purine content in 100 grams of yeast is 559 milligrams, which is indeed a high purine food. However, based on intake analysis, the recommended amount of yeast added is 0.5%.

That is to say, 5 grams of yeast can be made into about one kilogram of flour. The purine content is calculated according to 100 grams of staple food per person per meal, which can be ignored. Therefore, there is no need to worry too much about the increase in uric acid and gout caused by eating yeast Mantou.

What health value does yeast Mantou have that old Mantou doesn't have?

1) Helps improve gut microbiota

Yeast is a kind of biological probiotics, which can rapidly accumulate and reproduce in the intestinal tract after ingesting human body, helping to increase the proportion of probiotics in the intestinal tract and improve the quality of intestinal flora.

Yeast, after a certain degree of reproduction, can play a role in the gelatinization of starch, thereby helping the gastrointestinal tract to better absorb nutrients and reduce the burden of digestion.

2) Able to consume more comprehensive nutrients

In the fermentation process, yeast not only plays a role in puffing, but also makes Mantou soft and delicious. The fermentation itself will produce niacin, folic acid, protein, vitamin b and other nutrients, which will help Mantou to have more comprehensive nutritional value, and the body will also have more comprehensive nutrition.

In contrast, most of the nutritional benefits of Mantou made of old noodles fermented by natural bacteria are not as good as those of yeast Mantou, and the natural nutritional level is also slightly lower.

Yeast Mantou has a softer taste and is suitable for people with weak digestion ability. This is not to belittle the old flour Mantou. Strictly speaking, eating old flour Mantou will not cause obvious negative effects on the human body, but do not eat too much at one time to avoid burden on stomach digestion.

However, it is undeniable that the use of yeast is gradually replacing the old flour Mantou as the main process material for making Mantou.
