Ten unfavorable diets during pregnancy.
First, it is not suitable for high-fat diet: medical experts point out that although fat itself will not cause cancer, long-term addiction to high-fat food 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 child health. A large number of medical research data also confirmed that breast cancer, ovarian cancer and cervical cancer have a family genetic tendency, which is related to long-term high-fat diet. If pregnant women are addicted to high-fat foods, it is bound to increase the risk of their daughters suffering from reproductive system cancer.
2. Not suitable for high-protein diet: Medical research believes that insufficient supply of protein can easily weaken the physical strength of pregnant women, slow fetal growth, slow postpartum recovery and scarce milk secretion. Therefore, the daily protein requirement of pregnant women should reach 90- 100g. However, the high-protein diet during pregnancy will affect the appetite of pregnant women, increase the burden of gastrointestinal tract, affect the intake of other nutrients, and make the diet and nutrition out of balance. Studies have confirmed that excessive intake of protein will produce a lot of harmful substances such as hydrogen sulfide and histamine in the human body, which may easily cause abdominal distension, loss of appetite, dizziness, fatigue and other symptoms. At the same time, excessive intake of protein will not only increase the nitrogen content in blood, but also easily lead to the increase of cholesterol, thus increasing the burden of glomerular filtration function. Some scholars believe that the excessive accumulation of protein in human connective tissue will cause the degeneration of tissues and organs, and make people suffer from cancer.
Third, it is not easy to eat a high-sugar diet: medical scientists at the National Institute of Pisa, Italy, found that the probability of giving birth to an overweight fetus, the incidence of fetal congenital malformation, the probability of pregnancy-induced hypertension syndrome or the need for caesarean section were 3 times, 7 times and 2 times that of hypoglycemia pregnant women, respectively. On the other hand, the function of glucose excretion in pregnant women's kidneys can be reduced to varying degrees. If the blood sugar is too high, it will increase the burden on the kidneys of pregnant women, which is not conducive to health care during pregnancy. A large number of medical studies show that eating too much sugar will weaken human immunity, reduce the disease resistance of pregnant women, make them vulnerable to bacterial and viral infections, which is not conducive to prenatal and postnatal care.
Fourth, not suitable for high-calcium diet: pregnant women blindly ingest high-calcium diet, such as taking a lot of calcium tablets and vitamin D, which is harmful to the fetus. Nutritionists believe that if pregnant women consume too much calcium, the fetus may get hypercalcemia; After birth, the fontanel will close prematurely, the jaw will widen and protrude, the nose will lean forward and the aorta will narrow, which is not conducive to the growth and development of children and the beauty of future generations. Generally speaking, the daily calcium requirement of pregnant women in the early pregnancy is 800 mg, and it can be increased to 1 100 mg in the late pregnancy, without special supplementation, as long as it is taken reasonably from daily dairy products, fish, meat, eggs and other foods.
5. It is not advisable to eat salty food excessively: Some pregnant women like to eat salty food because of their eating habits, especially northern residents. Modern medical research believes that the amount of salt has a certain relationship with the incidence of hypertension, and the more salt intake, the higher the incidence. As we all know, pregnancy-induced hypertension syndrome is a unique disease of pregnant women. Its main symptoms are edema, hypertension and proteinuria. Severe cases may be accompanied by headache, dizziness, chest tightness, dizziness, and even eclampsia, endangering the health of mother and baby. Too much salty food in pregnant women can easily lead to pregnancy-induced hypertension syndrome. Therefore, experts suggest that the daily salt intake of pregnant women should be about 6 grams.
Sixth, 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, a study by German scientists found that if a mother ingests a large amount of acidic drugs or other acidic substances in the early pregnancy, it may affect the normal division, proliferation and development of embryonic cells, easily induce genetic material mutation, and lead to fetal malformation. With the development and maturity of the fetus, the pH value in its tissues and cells gradually approaches that of the mother, and the degree of influence will gradually decrease. Therefore, pregnant women should not use acidic drugs or acidic diet in the early pregnancy.
Seven, it is not appropriate to abuse warm supplements: pregnant women because of the obvious increase in blood flow in the systemic blood circulation system, the heart burden is aggravated, and the blood vessels of the cervix, vaginal wall and fallopian tube are also in a state of dilatation and congestion. In addition, the endocrine function of pregnant women is strong, and the secretion of aldehydes and sterols increases, which is easy to lead to water and sodium retention, edema, hypertension and other diseases. Furthermore, due to the decrease of gastric acid secretion and the weakening of gastrointestinal function, pregnant women will have symptoms such as loss of appetite, flatulence and constipation. In this case, if pregnant women often take warming tonics, such as ginseng, velvet antler, deer fetal glue, antler glue, longan, litchi, walnut kernel and so on. It will inevitably lead to yin deficiency and yang hyperactivity, qi disorder, blood-heat eruption, aggravated morning sickness, edema, hypertension, constipation and other symptoms, and even lead to abortion or stillbirth.
Eight, should not eat moldy food: pregnant women eat agricultural and sideline products and food contaminated by mycotoxins, not only acute or chronic food poisoning will occur, but even the fetus will be affected. Because in the early 2-3 months of pregnancy, embryo implantation develops, and embryonic somatic cells are in a stage of high proliferation and differentiation. The invasion of mycotoxin can break or distort chromosomes, leading to genetic diseases or fetal malformations, such as congenital heart disease and congenital stupidity, and some even stop the development of the fetus, causing stillbirth and abortion. On the other hand, in the second and third trimester of pregnancy, because the function of fetal organs is not perfect, especially the liver and kidney functions are very fragile, mycotoxins will also have toxic effects on the fetus. A large number of medical research data confirmed that mycotoxin is a strong carcinogen, which can cause maternal and fetal liver cancer and gastric cancer. In addition, if the mother has coma, vomiting and other symptoms due to food poisoning, it is also extremely unfavorable to the growth and development of the fetus.
Nine, it is not suitable for long-term vegetarianism: Some pregnant women pursue "bodybuilding" during pregnancy, or because of financial constraints, long-term vegetarianism is not conducive to the growth and development of the fetus. According to the research, if you don't pay attention to nutrition during pregnancy, the number of brain cells in the fetus will decrease due to the insufficient supply of protein, which will affect the future intelligence, and the fetus will be deformed or malnourished. If the fat intake is insufficient, it will easily lead to the birth of a low-weight fetus, and the baby's resistance is low and the survival rate is low; For pregnant women, anemia, edema and hypertension may also occur. Japanese medical scientists have found that babies born to vegetarian women often suffer irreversible brain damage due to the lack of vitamin b 12. Three months after birth, the baby gradually showed indifference, lost the ability to control the stability of the head, and appeared involuntary movements such as head and wrist. If not treated in time, it is easy to cause megaloblastic anemia and obvious nervous system damage.
10. Don't drink irritating drinks: Medical research has confirmed that alcohol can enter the fetus through the placenta after drinking, which has a direct toxic effect on the fetus, not only delaying the development of the fetus, but also causing deformities and defects of some organs, such as small head, small eyes, short chin, flat and narrow brain, short stature, and even heart and limbs malformation; Some fetuses are mentally retarded, stupid and prone to illness. After birth, it even causes lifelong illness and waste for future generations. Pregnant women drink strong tea because tea contains a lot of tannins, which can combine with protein in food and become insoluble tannins. Tannin can also agglutinate and precipitate with other nutrients in food, which affects the absorption and utilization of protein, iron, vitamins and other nutrients by pregnant women and fetuses, and then leads to malnutrition. Tea also contains a lot of tannic acid, which has astringent effect, affects intestinal peristalsis and easily causes constipation in pregnant women. Drinking more soda in pregnant women will cause iron deficiency and anemia in the body, which is not good for mother and baby. In addition, pregnant women drink more cold drinks and eat more raw and cold food, which may lead to fetal movement anxiety, abdominal pain and diarrhea.
"Six Eating and Six Not Eating" in Pregnancy Diet
Being pregnant, as a pregnant mother, we should pay attention to all aspects, especially our diet. So what should I eat and what should I not eat? You must know something in your heart. Here, I generally put forward the principle of "six eating and six not eating" during pregnancy for your reference. "Eat six times" means eating as much as possible; "Six don't eat" is to try to avoid these foods. Don't worry too much if you just touch it occasionally. Six to eat:
Whole wheat products, including porridge, graham crackers, whole wheat bread, etc. Especially for pregnant women in the north, you must replace the fried dough sticks with porridge for breakfast, although you will be somewhat unaccustomed. Cereals can keep you energetic and lower your cholesterol level. Of course, don't buy those sweet and refined cereals. Natural grains without sugar or other additives are the best. At this time, you can add some peanuts, raisins or honey according to your preference. Graham crackers snacks, chewing slowly, can effectively relieve morning sickness; Whole wheat bread can provide rich iron and zinc.
Second, milk and bean products. Pregnant women should consume about 1000 mg of calcium every day, and only 3 cups of skim milk can meet this demand. Yogurt is also rich in calcium and protein, which is good for gastrointestinal health. Some pregnant women are vegetarians. In order to get enough protein, they can only get the nutrition they need during pregnancy from bean products.
Third, fruit. Citrus and fruits are various and economical. Although 90% of them are water, they are rich in vitamin C, folic acid and a lot of fiber, which can help pregnant women maintain their physical strength and prevent fatigue caused by lack of water. Bananas can provide energy quickly and help pregnant women overcome fatigue. If your morning sickness is serious, eating bananas is easier for your stomach to accept.
Fourth, lean meat. Because lean meat is rich in iron, it is easily absorbed by the human body. During pregnancy, the total blood volume of pregnant women will increase. In order to ensure that the fetus has sufficient nutrition, the demand for iron by pregnant women will increase exponentially. If the iron stored in the body is insufficient, pregnant women will feel extremely tired, so it is extremely important to supplement enough iron through diet, especially lean meat.
Fifth, vegetables. Don't forget to add black lettuce when making western salad. Dark vegetables usually mean high vitamin content. Cabbage is a good source of calcium. You can add this fresh vegetable to soup or dumpling stuffing at any time. For spinach, it was once thought that it was rich in iron and was regarded as one of the vegetables that could prevent anemia during pregnancy. But recently, experts suggested that spinach does not contain much iron, but it contains a lot of oxalic acid that affects the absorption of zinc and calcium, so don't eat more spinach. Cauliflower has many advantages, such as being rich in calcium and folic acid, rich in fiber and antioxidants against diseases, and also helping to absorb iron from other green vegetables.
Sixth, dried fruits. Nuts such as peanuts contain unsaturated fats that are good for heart health. However, because the calorie and fat content of nuts are relatively high, the daily intake should be controlled at about 30 grams. Dried fruits such as preserved apricots, dried cherries and sour horns are convenient, delicious and portable, which can satisfy the desire of pregnant women to eat sweets at any time.
Six don't eat:
This is what we used to call taboo. This is not superstition. You really need to know that some foods are not suitable for pregnancy, because some foods that you usually like to eat will have adverse effects on the fetus if you eat too much during pregnancy.
First, spicy seasoning. Zanthoxylum bungeanum, Zanthoxylum bungeanum, pepper, fennel, star anise, cinnamon and spiced powder are easy to consume intestinal water and reduce gastrointestinal secretion, leading to stomach pain, hemorrhoids and constipation. When constipated, pregnant women hold their breath hard to relieve constipation, which increases abdominal pressure and oppresses the fetus in the uterus, which is easy to cause adverse consequences such as restless fetal movement and premature delivery. Many pregnant mothers prefer to eat sour hawthorn, but hawthorn has an exciting effect on uterus. Eating too much can cause uterine contraction and miscarriage, so eat less.
Second, an exciting diet. Caffeine-containing drinks and foods can cause nausea, vomiting, headache and rapid heartbeat when consumed in large quantities by pregnant women. Caffeine can also enter the fetus through the placenta, affecting fetal development. Tea is rich in caffeine. Drinking tea will increase the heart rate of pregnant women and increase the burden on the heart and kidneys, which is not conducive to the healthy development of the fetus.
Third, sweets. The metabolism of sugar in human body will consume a lot of calcium, and calcium deficiency during pregnancy will affect the development of fetal teeth and bones. Eating too much chocolate is not good, which will make pregnant women feel full and affect their appetite. Therefore, they are fat and lack the necessary nutrition.
Fourth, monosodium glutamate. MSG is a common condiment at ordinary times, but pregnant women should pay attention to eating less or not. The main component of monosodium glutamate is sodium glutamate, and zinc in blood is excreted from urine after combining with it. Excessive intake of monosodium glutamate will consume a lot of zinc, which is not conducive to the development of fetal nervous system.
Five, ginseng, longan and other supplements. Traditional Chinese medicine believes that most pregnant women are deficient in yin and blood, and eating people will cause excessive consumption of qi and yin, which will aggravate early pregnancy reaction, edema and hypertension. Longan warms the yang, and pregnant women eat it easily to replenish blood and abort; Therefore, it is inedible.
6. Foods containing additives. Additives and taboos contained in canned food are risk factors for teratogenesis and abortion, so pregnant mommy should stay away from canned food. Alum is an inorganic substance containing aluminum, which can invade the pregnant mother's "six eating six not eating" through the placenta.
