1 piece of fermented bean curd has 12 grams of salt? Can't eat for cardiovascular disease? Will it cause cancer? Those who dare not eat fermented bean curd

"You have high blood pressure, don't always eat fermented bean curd." Mrs. Liu said this to Mr. Liu almost every day.

"This can't be eaten, that can't be eaten, what's the strength of being alive!" Old Mr. Liu didn't give his wife any face, so he choked and took a half of fermented bean curd and stuffed it into his mouth.

Old Mr. Liu is a typical Chinese stomach. If he doesn't order fermented bean curd and pickles, he can't eat anything. Therefore, fermented bean curd is inseparable for almost three meals a day, especially breakfast.

But Mrs. Liu read an article in the circle of friends, heard that a piece of fermented bean curd contains 12g of salt, can be repeatedly explained by the doctor, should control high blood pressure. She was worried about her husband’s health, so she had to say, "I don’t listen to what I say, don’t you listen to what the doctor said?" Eating too much is really not conducive to blood pressure control.

1. Does 1 piece of fermented bean curd really have 12g of salt?

It is safe to say that 1 piece of fermented bean curd does not contain 12g of salt.

Before explaining this problem, I need to understand that fermented bean curd is not processed with a lot of salt, but a soybean product brewed using traditional fermentation technology.

Of course, will add a certain amount of salt during the fermented fermented bean curd, salt is added to the fermented bean curd not only to allow it to be stored for a long time, but to form a unique Craft. The salt can make the water in the tofu harden and help extract the protease from the mucilage, which can form the unique flavor of the fermented bean curd. If a large amount of salt is added in this process, it will affect the taste.

Therefore, a piece of fermented bean curd circulated on the Internet contains 12g of salt, which is unscientific. The salt content in fermented bean curd is much lower than this level. "Chinese Food Ingredients Table (Second Edition)" pointed out that the salt content of 100g fermented bean curd is about 2000mg, which means that you can consume about 10g fermented bean curd a day. , Equivalent to a piece of fermented bean curd, about 0.5 to 0.7 grams of salt will be consumed.

Fermented bean curd is a food on the Internet. There are various rumors on the Internet. In addition to the high salt content, there are also claims that fermented bean curd can cause cancer. This statement makes many people afraid to eat fermented bean curd.

2. Fermented bean curd can cause cancer, is it true?

Some people think that fermented bean curd is carcinogenic mainly due to two reasons. First, fermented bean curd contains nitrite; second,Contains aflatoxin .

If these two substances are taken out alone, they are indeed carcinogenic.

But!

remember this but!

does not contain these two substances in fermented bean curd, nitrite generally exists in processed meat and seafood, the purpose is to prevent food from spoiling. But the fermented bean curd does not produce nitrous acid . In other words, as long as you keep it safe after opening it, it will not cause cancer.

Secondly, fermented bean curd is called "mold tofu" in the folks. Some people think that it is the Aspergillus flavus that causes it to mold. Aflatoxin is produced during the production process, which can cause cancer if eaten. What we need to know is that mold is not the only species of Aspergillus flavus, sufu does need mold help in the production process, mainly Mucor , 2 Rhizopus etc.,These molds have nothing to do with aflatoxin, so aflatoxin is not produced at all.

Of course, these refer to unexpired and well-preserved fermented bean curd. Some fermented bean curd that has been left for too long will naturally contain aflatoxin.

At this time, someone will say that fermented bean curd does not contain high salt and does not cause cancer. Is it healthy food?

Fourth, fermented bean curd is very healthy, can people with cardiovascular disease eat it?

So, back to the original question, can cardiovascular patients like Mr. Liu eat fermented bean curd?

Although the salt content of fermented bean curd is not as exaggerated as the rumors, patients with cardiovascular disease should eat as little as possible. Because the fermented bean curd contains salt and purine content is high, itself suffers from cardiovascular disease patients, long-term consumption of fermented bean curd will bring a greater burden on blood vessels.
