Dietary principles during pregnancy, there are many kinds of food in our life, and most of them have different nutritional values. Of course, food is not suitable for everyone, and some people need to pay attention to many aspects in their diet. The following dietary principles during pregnancy.

Dietary principles during pregnancy 1 The diet in the first trimester is light and palatable, easy to digest, and conducive to reducing pregnancy reaction, including all kinds of fresh vegetables, fruits, bean products, fish, poultry, eggs and various cereal products. Eat less and eat more. According to the appetite and reaction of pregnant women, we should adjust the number, type and time of meals in time, eat less and eat more, and ensure the daily intake in the early stage.

First, choose digestible cereals, eat more foods rich in folic acid and supplement folic acid. It is recommended to supplement 400~800 micrograms of folic acid every day, quit smoking and ban alcohol. High-quality protein sources such as fish, poultry, eggs and lean meat should be appropriately increased in the second and third trimesters, with a daily increase of 50g in the second trimester and about 75g in the third trimester. Deep-sea fish should eat 2-3 times a week, and increase the intake of milk appropriately. From the second trimester, at least 250-500 grams of dairy products and 600 mg of calcium should be supplemented every day.

Appropriate increase in iodine intake during pregnancy, pregnant women should not only adhere to the use of iodized salt, but also eat more iodine-rich seafood, such as kelp, seaweed and so on.

Often eat foods rich in iron, increase red meat by 20 ~ 50g every day, eat animal viscera or blood products 1 ~ 2 times a week, and eat less irritating food.

Four dietary principles of pregnancy diet.

First, you can't diet. Many female friends are worried that pregnancy will make them lose their shape and have been dieting to lose weight. However, during pregnancy, pregnant women should not go on a diet to ensure the nutritional needs of fetal growth and development. Dieting during pregnancy will lead to insufficient nutrition intake and unbalanced diet, which may lead to the lack of some special elements for pregnant mothers, which is not good for pregnant mothers and babies.

Second, make a diet plan. Pregnant mothers are very demanding about their diet during pregnancy. In order to ensure adequate, rich and balanced nutrition intake, we must carefully arrange our own diet, formulate healthy recipes, eat in an orderly manner according to the nutrition supplement plan, and supplement nutrition. The diet of pregnant mothers is very important, so it is necessary to spend more time and eat foods rich in various nutrients reasonably.

Third, eat less and eat more. Usually three meals a day, pregnant mothers increase in moderation. In order to supplement nutrition, they have to add meals. It is generally recommended that pregnant mothers eat a meal every four hours. Some pregnant mothers still have the problem of pregnancy vomiting, so they should choose a diet plan that eats less and eats more meals.

Fourth, you can't blindly take health care products. Some pregnant women like to take some health care products during pregnancy, hoping to supplement nutrition and recuperate their bodies. It is really necessary to supplement nutrition during pregnancy, but many health care products contain hormones, which is not good for fetal development.

Pregnant mothers cannot go on a diet during pregnancy. They should consult a nutritionist, make a healthy and scientific diet plan, adhere to the basic principle of eating less and eating more meals, and don't blindly eat health care products. In order to ensure the nutrition needed for fetal development during pregnancy, pregnant mothers need to supplement nutrition and cannot go on a diet. They can eat less and eat more. It is not recommended to eat health care products blindly, which will adversely affect fetal development.

Diet principle during pregnancy 2 What should I pay attention to during pregnancy?

Raw food has become a dietary trend.

In recent years, raw food has become a new trend of food culture. After criticizing the common cooking methods such as steaming, boiling, frying and frying. Raw food has become the mainstream of people's daily diet because of its characteristics of preserving the true color of food, being oil-free and salt-free, and not losing nutrition.

Although unprocessed food will retain more nutrients, some nutrients need to be obtained from cooked food. For example, the best source of antioxidant lycopene is cooked tomato food. A large number of studies show that antioxidant lycopene can reduce the risk of prostate cancer and liver cancer. Another example is that after carrots are cooked, a large amount of carotene absorbed by the human body is one of the effective anti-cancer antioxidants.

Eating raw doesn't mean not touching cooked food.

Long-term restricted food selection may lead to malnutrition. Long-term consumption of unprocessed food will greatly reduce the intake of fatty acids and some nutrients such as linolenic acid and linoleic acid. Studies have shown that vegetarians who only eat raw vegetables will have low bone mass, which is usually an early indicator of diseases such as osteoporosis. What pregnant women need is balanced nutrition, and the lack of any nutrient element may have a fatal impact on their children.

In addition, eating raw fish, meat, eggs and other foods during pregnancy is prone to parasitic infection. In addition, the hygienic quality of raw food is difficult to master, and it is easy to cause gastroenteritis and diarrhea due to bacterial infection. Therefore, for the safety of themselves and their babies, expectant mothers had better avoid eating this kind of food raw.

The principle of pregnancy diet 3 must know the diet during pregnancy.

Early pregnancy (0 ~ 3 months):

Early pregnancy is the formation period of various tissues and organs of the embryo, the key period of fetal growth and development, and the most teratogenic period of the fetus. During this period, pregnant women often have different degrees of pregnancy reactions, such as nausea, vomiting, loss of appetite and so on. At this time, we should pay attention to the diversification of diet, rich and comprehensive nutrition, mainly light and greasy, and eat less and more meals.

If the pregnancy reaction is great and the food you eat vomits, you should continue to make up. At the same time, we should be careful not to eat too cold food, such as crabs and turtles, so as not to cause miscarriage;

There are also cold, irritating and greasy foods to eat as little as possible; Avoid alcohol and tobacco, avoid drinking strong tea, coffee and other stimulating drinks; Do not touch radioactive or harmful substances; Try to avoid diseases such as colds, and be careful when using drugs at this time, otherwise it will cause fetal malformation. Once you get sick, tell the doctor that you are pregnant, so that the doctor can pay attention to this factor when prescribing medicine for you.

Second trimester (April to June):

In the second trimester of pregnancy, the pregnant reaction of pregnant women basically disappears, the appetite tends to improve, the appetite increases greatly, and the fetal development accelerates, so the variety of food should be more diversified. In order to ensure the supply of heat energy, it is necessary to increase the intake of a certain amount of staple food; The oil can be mainly vegetable oil; Eat more foods containing protein, such as meat, fish, milk, eggs, bean products and seafood.

Eat more calcium-containing foods, such as cheese, shrimp skin, kelp, bones, bone soup, celery, rape and so on. Eat more iron-containing foods, such as animal liver, animal blood, black fungus, black sesame, spinach, carrots, cucumbers and so on. Eat more foods containing zinc, such as shellfish, animal kidneys, Chinese cabbage, lentils, eggplant and white radish. Eat more foods with high folic acid content, such as lettuce leaves, leeks, green onions, potatoes, day lilies, lotus roots and so on. Eat foods containing vitamin E, such as corn and wheat germ;

Eat more foods containing vitamin D, such as eggs, and get more vitamin D in the sun. Eat more foods containing vitamin C, such as oranges, tomatoes, green peppers, cabbage, cauliflower and so on. Foods containing iron, zinc, vitamins and folic acid should be eaten 1 ~ 2 times a week. Eat milk, beans and bean products, eggs, dried shrimps, green leafy vegetables and fruits every day. If pregnant women have calf twitching, it may be calcium deficiency. If it is calcium deficiency, calcium should be supplemented in time.

The World Health Organization suggests that folic acid can be properly supplemented throughout pregnancy. Because the amount of folic acid needed during pregnancy is relatively large. At the same time, on the basis of paying attention to the balanced diet and nutrition, calcium and iron can be supplemented appropriately. But the supplement of these substances should be carried out under the guidance of a doctor.

Late pregnancy (after 7 months):

The third trimester of pregnancy is the fastest period of fetal growth and development, and also the fastest period of fetal brain cell proliferation. Therefore, the nutritional supply in the third trimester should reach or exceed the mid-term level. In addition to eating the above foods every day, pregnant women should also appropriately supplement foods that are beneficial to the development of fetal brain, such as walnuts, shrimps, mushrooms, etc. ), as well as foods containing iodine such as kelp and laver. The principle of diet is to eat less and eat more meals, and the number of meals per day can be increased to five or six.

At the same time, we should keep the acid-base balance in the body. Fruit can eat some apples, bananas, oranges, dates, grapes, lemons and so on.

Pregnant women in this period are prone to edema, so salt intake should be controlled. Those with obvious edema of lower limbs should avoid foods with high salt content such as bacon, salted fish, pickles, pickled mustard tuber and pickles.

Dietary taboos of pregnant women

Chinese medicine believes that pregnant women should try to eat less greasy food, such as rice kernels, hawthorn, water chestnuts, etc., because these foods have an exciting effect on the uterus, which is easy to cause uterine contraction and lead to abortion. Try to eat as little hot food as possible, such as dog meat, peppers and ginseng. Trace elements can be supplemented if they are lacking, and they need not be supplemented if they are not lacking. If you blindly ingest a vitamin or trace element that you don't need, it may be counterproductive.

For pregnant women with twins, because both fetuses need a lot of various nutrients, the intake should be more than that of pregnant women with singletons. So it is recommended to eat more meals and eat food when you feel hungry. At the same time, we should be careful not to be tired, pay attention to rest, go to the hospital for regular check-ups on time, and go to the hospital early for labor. Pregnant women can take a cold bath, but be careful not to catch a cold and try to eat less cold drinks.
