Which nuts can't pregnant women eat?

Although most nuts are beneficial to the physical maintenance of pregnant women and the healthy development of the fetus, they should not be eaten more. Nuts are oily, but the digestive function of pregnant women is relatively weakened during pregnancy. Excessive consumption of nuts can easily cause indigestion. In addition, many dried fruits are fried and pickled in the processing process, and excessive consumption can easily lead to excessive fire. Although dried fruits are beneficial to the body, they should be eaten in moderation, and nuts should not exceed 50 grams a day, especially those who eat them regularly. The following six kinds of nuts should not be eaten by pregnant women:

1, spicy. Nuts contain a large number of unsaturated fatty acids, which will lead to rancidity if stored improperly or for a long time, resulting in what we often call "spicy taste". Fatty acids in nuts are rancid, which is harmful in that, on the one hand, it makes the taste of nuts worse and produces a pungent taste. On the other hand, rancidity products of oil in nuts, such as aldehydes and ketones with small molecules, also threaten health. If you eat a lot, it will cause diarrhea, and in severe cases, it may also cause liver disease. Nut vendors are generally reluctant to throw away spoiled nuts, and the best way to cover up the "spicy taste" is to add a lot of salt, pepper, aniseed, saccharin, essence, etc. for seasoning during processing, so spoiled nuts are often hidden in salty, spiced and creamy nuts. In contrast, the quality of plain and stir-fried nuts is relatively better.

2, moldy. Many nuts are easily contaminated by Aspergillus flavus, which produces a highly toxic substance-aflatoxin, which can cause people to have a fever, vomit and even be life-threatening. Aflatoxin also has a strong carcinogenic ability, which has great damage to human organs. Therefore, moldy nuts must not be eaten. Once the nuts in your mouth are found to be bitter, musty or spicy, spit them out and rinse your mouth in time.

3, fried. Nuts contain a lot of fat, protein and carbohydrates, and ordinary heating is not enough to destroy them. However, when the nuts are scorched, the temperature is already above 200℃. At this time, these nutrients, which were originally beneficial to the body, begin to partially transform into carcinogenic substances such as benzopyrene, heterocyclic amines and acrylamide. Therefore, the roasted nuts are not suitable for eating.

4. It has been beautified by paraffin. On the one hand, adding paraffin when processing nuts will make the products brighter and sell better, and it is not easy to become damp and soft. If the nuts you see are shiny and obviously "beautiful" than ordinary nuts, it is likely that paraffin is added; On the other hand, some vendors add paraffin wax to the long-standing backlog of nuts with bad color to "beautify" them and use them as inferior products. The industrial paraffin used by vendors is not pure, and it contains impurities such as heavy metals, which is harmful to health.

5, the taste is too heavy. First of all, the heavier the taste, the more salt is added; Secondly, many nuts with heavy taste and strong fragrance are processed with essence, saccharin and other substances, and butter-flavored nuts are also added with margarine, which is not good for the body; Finally, the heavier the taste of nuts, the greater the possibility of hidden deterioration behind their delicacy.

6. The dust is scattered. Responsible merchants will pay attention to the cleanliness of nut raw materials and the dust prevention of products. There are also many products on the market with many impurities such as dust in raw materials and no cover when selling. Therefore, when consumers buy, it is best to look at the bottom of the vessel containing nuts carefully. Unclean nuts often fall a layer of ash under the vessel.
