Fried food, pickled food, biscuits, sausages, candied fruit, ice cream, dried meat, soda, barbecue and canned food. These foods are characterized by high calories, high salt, high sugar, high preservatives, high spices and saturated fatty acids, which not only have no nutritional value, but also are a burden to the body.

Second, avoid food that is easy to cause miscarriage.

1. Aloe: According to the data provided by chinese institute of food science and technology, if pregnant women drink aloe juice, it will lead to pelvic bleeding and even abortion.

2. Crabs and soft-shelled turtles: they are cold and have the function of promoting blood circulation and removing blood stasis, so they are not good for pregnant women, especially the feet, which have obvious slippery effects.

3. Coix seed: also known as Coix seed, it has an exciting effect on uterine smooth muscle and can promote uterine contraction, thus it may induce abortion.

4. Portulaca oleracea: Experiments have proved that Portulaca oleracea juice has obvious exciting effect on uterus, which can increase the number and intensity of uterine contractions and easily cause miscarriage.

5. Auricularia auricula: it has the function of promoting blood circulation and removing blood stasis, which is not conducive to the stability and growth of embryos, so it is forbidden to eat.

6. Almonds: Almonds contain highly toxic hydrocyanic acid, which can suffocate the fetus, so pregnant women should fast.

Three, pregnant women should not eat vegetables

As we all know, pregnant women should eat more fresh vegetables, which are beneficial to the nutritional supplement of pregnant women and the development and growth of the fetus, and can also avoid the harmful effects of exposure to chemicals on the baby. However, not all vegetables are suitable for pregnant women. Du Lijuan, a senior nutritionist (chief nutritionist of Aidi Palace Yuezi Center), pointed out that pregnant women should avoid eating foods that can promote blood circulation, remove blood stasis and promote uterine contraction.

1. Eggplant: Eggplant is a cold vegetable. Pregnant women who have indigestion, diarrhea, spleen and stomach deficiency and loose stool symptoms should not eat more. Pregnant women friends should also choose fresh eggplant when choosing eggplant. It is best not to choose old eggplant, especially after autumn, which contains more solanine, which is harmful to human body and should not be eaten more.

2. Portulaca oleracea: it is cold and greasy, which has obvious exciting effect on the uterus and is easy to cause premature birth.

3. Agaricus campestris: Agaricus campestris is cold and cold, which has the disadvantages of smoothing and cooling blood. Pregnant women should not eat it. Especially in the early pregnancy and pregnant women with habitual abortion, they should not eat it.

4. Sagittarius: Sagittarius has the function of promoting blood circulation, especially in the early pregnancy and those with a history of habitual abortion, and should not eat it.

5. Amaranth: "Compendium of Materia Medica" records that amaranth has slippery tires, so pregnant women should eat it carefully.

6. Kelp: According to research, iodine deficiency in pregnant women will affect fetal dysplasia, resulting in low intelligence, so pregnant women should eat some kelp to supplement iodine in the body. However, it should be noted that if pregnant women take kelp excessively, too much iodine can cause fetal thyroid development disorder.

7. Long-lived potatoes: Potatoes contain alkaloids, and the longer they are stored, the higher the alkaloid content. Eating this potato can affect the normal development of the fetus and lead to fetal malformation. Potatoes that germinate or turn blue are also not suitable for eating.

8. Spinach: Oxalic acid in spinach affects the body's absorption of calcium and zinc. Excessive intake by pregnant women will reduce the content of calcium and zinc in the body and affect the baby's growth and development.

Fourth, avoid eating a variety of condiments

Hot condiments: Fennel, Zanthoxylum bungeanum, pepper, cinnamon, pepper, garlic, star anise, spiced powder and other condiments are highly irritating, which easily consumes intestinal water, reduces gastrointestinal secretion, and causes intestinal dryness and constipation. After constipation occurs, pregnant women will inevitably hold their breath to relieve constipation, which will increase abdominal pressure and oppress the fetus in the uterus, which will easily lead to adverse consequences such as restless fetal movement and premature delivery.

Monosodium glutamate: The main component is sodium glutamate, and the zinc in the blood is discharged from the urine after combining with it. Eating too much monosodium glutamate can affect the absorption of zinc, leading to zinc deficiency in pregnant women, which is not conducive to the development of fetal nervous system.

Five, pregnant women should not drink drinks

Royal jelly: Because it contains hormone substances that will stimulate the uterus, cause contractions, interfere with the growth of the fetus in the uterus, make the fetus too large, cause pain to the pregnant mommy, and increase the hormones in the fetus, causing false precocity after delivery.

Strong tea, coffee, cola: These drinks contain caffeine or clonine to a greater or lesser extent, which has an exciting effect on the central nervous system. Only a small amount can be drunk during pregnancy, and excessive drinking will cause harm to the baby.

Cold drinks and soft drinks: the gastrointestinal function of women is weakened after pregnancy. Too cold food will cause the gastrointestinal blood vessels to contract suddenly, and the digestive function will be weakened, resulting in symptoms such as diarrhea and abdominal pain. Soda will consume iron in expectant mothers, which will lead to anemia and affect the baby's development.

Alcohol: If you drink too much alcohol, it will make the fetus deformed and affect the IQ and physiological development of the fetus. Try to avoid drinking alcohol during pregnancy.

Six, pregnant women should not eat fruit

In fact, there are no fruits that pregnant women must not eat, but many fruits that pregnant women must eat less, such as watermelon, pineapple, grapes, kiwifruit and other fruits, have higher sugar content, and pregnant women with obesity and family history of diabetes should eat less.

Hot fruits such as litchi and longan are easy to cause dry stool; Persimmon is easy to cause stomach stones; White melon, cantaloupe and peach are easy to cause diarrhea; Jackfruit and durian are easy to cause loss of appetite; Yangmei is easy to cause hyperacidity, so pregnant women should eat carefully.

Hawthorn has a certain contractive effect on uterus, and pregnant women with a history of abortion should "stay away from it". Apricot has the function of slippery fetus and is not good for teeth, so pregnant women should eat it carefully. If pregnant women are anaemic, they should also eat less pomegranate.

It is best for pregnant women to choose mild fruits such as apples, cherries, strawberries and oranges, but be careful not to overdo it. It is best for pregnant women to eat no more than 500 grams of fruit every day, and the amount of pregnant women with diabetes should be halved. It is advisable to eat fruit between two meals, which not only supplements vitamins in time, but also does not hinder the intake of other nutrients.

Seven, pregnant women should not eat other food.

Ginseng and ginseng products: Ginseng is a warm tonic. Due to physiological changes during pregnancy, eating ginseng or ginseng products at this time will aggravate symptoms such as morning sickness, edema, hypertension, constipation, etc., and because ginsenoside can promote uterine contraction, it may induce abortion and premature delivery.

Pig liver: Finland and the United States have advised pregnant women to eat less pig liver. Because too many fattening agents are added to the modern feed that fattens livestock quickly, and the content of vitamin A is very high, which causes it to accumulate in the liver of animals. When pregnant women overeat pig liver, a large amount of vitamin A will easily enter the body, which is very harmful to fetal development and even teratogenic.

Cold food: sashimi, lettuce, etc. often contain bacteria, pesticides, etc. It is easy to diarrhea when eaten raw, which is not conducive to the fetus.

Other foods: shark wings, foie gras, puffer fish, civet cats and other pregnant women must stay away. These foods that are not often eaten in normal life will be harmful to the fetus.

Eight, pregnant women should not diet principle.

In terms of diet, pregnant women should pay attention to many things. Generally speaking, we should grasp the following principles.

1. Not suitable for high-calcium diet: pregnant women blindly ingest high-calcium diet, such as taking a large number of calcium tablets and vitamin D, which is harmful to the fetus. If the daily dairy products, fish, meat, eggs and other foods are reasonably ingested, it is necessary to follow the doctor's advice to supplement calcium.

2. Not suitable for high-fat diet: Medical experts point out that long-term addiction to high-fat foods will increase the concentration of cholic acid and neutral cholesterol in the large intestine, and the accumulation of these substances can induce colon cancer. At the same time, high-fat food can increase the synthesis of prolactin and promote the occurrence of breast cancer, which is not conducive to maternal and infant health.

3. Not suitable for high-protein diet: The daily protein requirement of pregnant women should reach 90 ~100g. A high-protein diet beyond this value can affect the appetite of pregnant women, increase the burden of gastrointestinal tract, and affect the intake of other nutrients, so that the diet and nutrition are out of balance.

4. Not suitable for high-sugar diet: the metabolism of sugar in the human body will consume a lot of calcium, and the lack of calcium during pregnancy will affect the development of fetal teeth and bones.

5. It is not appropriate to eat too salty food: Excessive salty food for pregnant women is easy to cause pregnancy-induced hypertension syndrome. Therefore, experts suggest that the daily salt intake of pregnant women should be about 6 grams.

6. It is not suitable for eating acidic diet: Pregnant women may have early pregnancy symptoms such as picky eaters, loss of appetite, nausea and vomiting in the early pregnancy, and many people like acidic diet. However, if the mother ingests a large amount of acidic drugs or other acidic substances in the early pregnancy, it may affect the normal division, proliferation, development and growth of embryonic cells, and easily induce genetic material mutation, leading to fetal malformation.

7. It is not advisable to take warm supplements excessively: pregnant women's blood flow in the whole body's blood circulation system is obviously increased, the heart burden is aggravated, and the blood vessels in the cervix, vaginal wall and fallopian tube are also in a state of expansion and congestion. In addition, the endocrine function of pregnant women is strong, and the aldehyde sterols secreted are increased. Excessive use of warm supplements can easily lead to water and sodium retention, resulting in edema, hypertension and other diseases.

8. Not suitable for eating moldy food: When pregnant women eat agricultural and sideline products and food contaminated by mycotoxin, not only acute or chronic food poisoning will occur, but even the fetus will be affected.

9. Do not drink irritating drinks: Medical research has confirmed that alcohol can enter the fetus through the placenta after drinking alcohol, which directly has a toxic effect on the fetus, which not only slows down the development of the fetus, but also causes deformities and defects of some organs.

10. It is not suitable for long-term vegetarianism: Some pregnant women may reduce the number of fetal brain cells in order to pursue the figure during pregnancy, or vegetarians may be vegetarian for a long time, which may affect their intelligence in the future, and may also cause fetal malformation or malnutrition. For pregnant women, anemia, edema and hypertension may also occur.
