Leaving aside whether it is hygienic or not, pickled foods such as sauerkraut are loved and feared by many people - they like their flavor but are worried that eating them will affect their health

So, is this worry overblown or is it really necessary? Science and Technology Daily reporters interviewed food and nutrition experts to see what they have to say

No long-term consumption in large quantities without cancer risk

"Sauerkraut is a type of pickled cabbage, also known as salted fermented vegetables

Pickled cabbage contains a lot of dietary fiber and plant enzymes, which not only can promote gastrointestinal digestion, but also increase appetite

However, the claim that pickled foods such as sauerkraut contain nitrite and cause cancer has been rampant, which has discouraged some people from sauerkraut

In this regard, Wang Hao said that nitrite does have direct and potential harm to the human body

"However, you don't need to talk about the discoloration of nitrite.

"In the early stage of fermentation, under the action of nitrate reductase, a large amount of nitrate in vegetables is converted into nitrite, and the nitrite content will increase sharply

"The change in nitrite content during the fermentation process will show a process from peak to trough, which is inevitable

Look for lactic acid bacteria fermentation when purchasing sauerkraut

Although sauerkraut of qualified quality can be eaten with confidence, consumers still need to pay attention to some issues when purchasing

For traditionally fermented sauerkraut, it is best to soak it in water before eating and wash it carefully, which can also wash off most of the nitrite

"At the same time, when choosing sauerkraut, look at the ingredient list.

These people should eat less pickled food

Although pickled foods have attracted many people with their unique flavor, Tan Guijun, chief physician of the Nutrition Department of Tianjin First Central Hospital, still pointed out in an interview with a reporter from Science and Technology Daily that pickled foods can be eaten but should not be eaten too much

“From a nutritional point of view, we recommend eating fresh, unprocessed foods best, as cooking loses a lot of nutrients

In addition, many pickled foods are added with a lot of salt in order to keep them fresh
.
It is now well established that sodium intake is associated with high blood pressure
.
"Especially in northern China, the salt intake can reach 18 to 28 grams per day, so the prevalence of hypertension has always been high
.
" Tan Guijun said that for healthy people, the daily salt intake should not exceed 6 grams, Patients with high blood pressure and kidney disease need to reduce their doses, so these people should eat less sauerkraut
.

In addition, some special groups also recommend eating less sauerkraut
.
Because nitrite has a very strong penetrating power, it can directly penetrate the placenta and enter the fetus' body, thereby having an effect on the fetus, so pregnant women should eat less sauerkraut
.
In addition, when nitrite is metabolized by the liver, it will not only increase the burden on the liver, but may also partially remain in the liver, aggravating the degree of liver damage.
Therefore, patients with liver disease should also eat less
