In fact, there are many kinds of tofu in China, such as white tofu, red tofu and colorful tofu. These are common bean curd brains in life, which have been circulating in China for a long time. But recently, many people think that tofu should not only be fermented, but also preserved, which is very bad for the health and may even cure cancer. Is this statement correct?
Let's get to know each other.
Bean curd is made by fermentation in the production process, so many people think that bean curd contains aflatoxin. In fact, tofu and dried tofu are fermented by mold during the production of tofu milk.
Simplify the process flow of sufu, which is roughly as follows:
(1) making tofu; (2) adding microorganisms for fermentation; (3) adding soup stock for curing; (4) adding fermented bean curd products.
Many people say that eating tofu often increases the risk of cancer, and tofu is also called moldy tofu.
Aflatoxin is a fungal substance produced by Aspergillus flavus fermentation and a strong carcinogen.
In fact, Aspergillus flavus is not used to ferment tofu, and bacteria such as Mucor and Rhizopus do not produce aflatoxin.
Some people say that tofu contains a lot of nitrite, which is easy to cause cancer when eaten. Tofu is not a pickled food, and the raw material of tofu belongs to soybean, and the nitrate content is not high, so a lot of nitrite will not be produced during fermentation.
Usually, as long as we buy regular packaged tofu brain from regular manufacturers, it has been tested for food, and everyone can eat it with confidence.
1: Studies have found that occasionally eating a small amount can help people control their blood pressure.
The content of protein in sufu is very high. Under the action of various beneficial molds, amino acids and peptides beneficial to human body are formed in sufu. These peptides can inhibit the activity of enzymes in blood vessels, thus helping the human body to lower blood pressure. However, the salt content of sufu is still very high after all, and patients with hypertension can only eat a little.
2. Help control the content of cholesterol in the blood.
Sufu is made of bean products. It contains a lot of unsaturated fatty acids, which can combine with cholesterol in the blood and inhibit the absorption of cholesterol. Animal studies show that protein contained in sufu can neutralize cholic acid, reduce the cholesterol level in animals, and control the blood lipid of animals to some extent. For patients with high cholesterol, a proper amount of fermented bean curd is edible.
3. It helps to prevent osteoporosis.
Osteoporosis is becoming more and more common in middle-aged and elderly people, which is closely related to calcium loss and bone mineral density reduction caused by aging, especially in menopausal women, who often have symptoms of backache.
Sufu retains the nutrition of bean products, and its soybean isoflavone can improve the osteoporosis of menopausal women and effectively regulate estrogen. Menopausal women, eating fermented bean curd in moderation is good for their health.
4. It can prevent Alzheimer's disease.
Under the action of various microorganisms, sufu will produce a certain amount of vitamin B 12, which, together with the zinc contained in it, can provide nutrition for the development of human brain.
It contains vitamin B 12, which is second only to animal viscera, and has the function of preventing Alzheimer's disease. Eating a little can make brain cells develop well.
Patients with hyperuricemia and gout
The raw material of bean curd is soybean, which is a high purine food. For people with high uric acid or gout, usually eat less tofu milk, which will easily lead to the increase of uric acid, which is not conducive to the stability of the disease.
Diabetic population
As we all know, the risk of cardiovascular disease in diabetic patients is 2-4 times that of ordinary people, and more than two-thirds of diabetic patients eventually die of cardiovascular disease.
The main raw material for making tofu is tofu, which belongs to bean products with relatively low sugar content, but tofu belongs to pickled fermented products.
And it contains a lot of salt, so diabetics can't eat too much. Excessive salt intake in diabetes will affect blood pressure, lead to an increase in blood pressure, increase the burden on liver and kidney, which is not conducive to health and will affect the condition of diabetes to a certain extent.
Patients with Helicobacter pylori infection and gastritis
Helicobacter pylori infection can cause many stomach diseases. This kind of harmful bacteria especially likes to breed in high sodium environment, so this kind of people had better not eat tofu milk, otherwise it will easily lead to the aggravation of stomach diseases.
