Although most nuts are beneficial to the health care 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. Eating too much nuts is easy to cause indigestion. In addition, many dried fruits are fried and pickled in the processing process, and excessive consumption is easy to get angry. Although dried fruits are good for your health, you should eat them in moderation. Nuts should not exceed 50 grams a day, especially those who eat them regularly. The following six nuts should not be eaten by pregnant women:

1, spicy. Nuts contain a lot of unsaturated fatty acids, which will lead to rancidity and produce what we often call "spicy taste" if stored improperly or for a long time. Fatty acids in nuts are rancid, which is harmful in that, on the one hand, it makes the taste of nuts worse and produces pungent taste. On the other hand, rancidity products of oil in nuts, such as small molecular aldehydes and ketones, also threaten health. Eating too much will cause diarrhea, and if it is serious, 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 and so on. Used for seasoning during processing, so spoiled nuts are often hidden in salty, spiced and creamy nuts. In contrast, the quality of vegetarian fried nuts is relatively better.

2, moldy. Many nuts are easily contaminated by Aspergillus flavus, which can produce a highly toxic substance-aflatoxin, which can make people have a fever, vomit and even endanger their lives. Aflatoxin also has a strong carcinogenicity and does great harm to human organs. So 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 burnt, the temperature is above 200℃. At this time, these nutrients that were originally beneficial to the body began to be partially transformed into carcinogens such as benzopyrene, heterocyclic amines and acrylamide. So roasted nuts are not suitable for eating.

It is 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 as inferior products. The industrial paraffin wax used by vendors is impure and 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 health; Finally, the heavier the taste of nuts, the greater the possibility of hidden deterioration behind their delicious taste.

6. The dust has dispersed. Responsible merchants will pay attention to the cleanliness of nut raw materials and the dust prevention of products. There are also many products in the market with many impurities such as dust in the raw materials, and they are sold without a cover. Therefore, when consumers buy, it is best to take a closer look at the bottom of the container containing nuts. Dirty nuts often leave a layer of ash under the utensils.
