American researchers have recently found that women who are obese before pregnancy are more likely to give birth to a deficient baby than women with normal weight.
Researchers from 1997 to 2002, was born more than 10,000 birth defects in newborns and their mother after an investigation found that pre-pregnancy body obese women born children likely to suffer from spina bifida is twice the normal weight women . Other birth defects associated with maternal pre-pregnancy obesity include the heart, anus, limbs, diaphragm and navel.
Women who are overweight before pregnancy, but who do not reach the level of obesity, have the possibility of birth defects and are larger than women with normal weight, but less likely than obese women.
What obesity is?
To assess obesity or not, the most common is the body mass index BMI (weight/height, Kg/m) calculated using height and weight. The ideal weight of each person varies according to height, based on BMI=22, between 18.5-24 is the standard physique; below 18.5 is too light; above 24 is overweight; if BMI exceeds 27 Even if it is obese.
In addition, waist and body fat can also be used as an assessment tool for obesity. If the male waist is greater than 90 cm and the female waist is greater than 80 cm, it is obese. But even if the body weight is not heavy and the waist circumference is not large, if the body fat of men over 30 years old is more than 25% and the body fat of women is more than 30%, it is considered an obese group.
Therefore, losing weight is not only to lose weight, but also to effectively reduce waist and body fat, in order to achieve a true healthy position!
Reasonable range of weight gain for pregnant women
During pregnancy, women’s weight must increase, including the weight of the fetus, amniotic fluid, placenta (about 4 kg), and the amount of blood increased in response to possible blood loss, as well as the increase in the uterus and breasts during pregnancy. Additional moisture retention and weight of subcutaneous fat deposition. In general, pregnant women gain an average weight gain of 10-12 kg throughout pregnancy.
However, depending on the underweight, standard or overweight condition before pregnancy, each person’s weight gain during pregnancy may vary. Pre-pregnancy weight standard, the weight of pregnancy is recommended to increase by 11.5-16 kg; if the weight before pregnancy, the weight of pregnancy should increase by 12.5-18 kg; if it is too heavy before pregnancy, the weight of pregnancy is recommended to increase only 7-11.5 kg .
Estimation of calories during pregnancy
The amount of heat required during pregnancy varies from period to period, and the higher the amount of heat required each day, the later. The daily intake of calories for pregnant women can be estimated by a simple formula: ideal weight × 40 calories + 300 calories, but should be adjusted at any time depending on the rate of weight gain.
Obesity, the enemy of pregnancy!
- Weight loss is best done before pregnancy
Most women who are obese before pregnancy lack healthy living habits, such as regular exercise, as well as low-sugar, low-salt, low-oil, high-fiber diets. It is recommended that women lose weight before pregnancy, with diet and exercise control, with a two-pronged approach, with a target of 0.5-1 kg per week. If the weight still exceeds the standard range during pregnancy, it is not recommended to continue to lose weight during pregnancy, as long as the weight control rate is strictly controlled.
- Pre-pregnancy obesity will greatly increase the risk of pregnant women and fetuses!
Excessive weight or obesity before pregnancy, or excessive weight gain during pregnancy, will increase the risk of gestational diabetes, high blood pressure, pre-eclampsia, and the chances of dystocia in production, caesarean section will increase, will also increase The risk of hyperplasia in the fetus and hypoglycemia after birth. Therefore, it is important to maintain proper weight before and during pregnancy!
- “One person eats, two people make up”? Beware of all fat in pregnant women!
Although the problem of over-nutrition in today’s society is already greater than malnutrition, most elders or pregnant moms still have the concept of “one person eats and two people fills up”, and believe that eating more will give birth to healthy children. Therefore, in addition to the early pregnancy may cause loss of appetite due to pregnancy reaction, most pregnant women in pregnancy, usually like being lifted, tonic, and even more than a day, making the weight rise.
As mentioned above, the weight of the fetus plus amniotic fluid, placenta, etc., but 4-5 kg, if the pregnant mommy gains too much weight, especially in the early stages of pregnancy, only to increase their own fat, does not help the fetus. Therefore, how to choose a diet that is good for health and does not increase the burden of weight is the most important task for pregnant women!
Healthy eating principles for pregnant women
- Sugar food:
This is the main source of body heat, you can’t stop eating, but you must learn the correct food substitute. Such as corn, yam, pumpkin, potato, sweet potatoes, rice, pasta, etc., are considered staple foods, the total amount of a meal is no more than one bowl. In addition, rejecting non-essential sugars such as candy, biscuits, cakes, and sugary drinks can avoid excessive heat intake.
Animal protein is superior to plant protein, so it should be taken in moderation. Eggs are a good source of protein, but you should pay attention to the intake of egg yolk to avoid high cholesterol. It is recommended to have 2-3 egg yolk a week. Cooking methods should be more steamed, boiled, and grilled to avoid frying and frying, so as not to ingest too much cooking oil.
If you need oil when cooking, try to replace animal oil with vegetable oil. Meat should be selected from lean meat, or white meat (chicken, fish) instead of red meat (pork, beef, lamb) to reduce oil intake; while eating, you can peel off the skin, cut off the oil, and avoid Eat too much fat.
Boiled water is the healthiest drink. It is recommended to drink more than 2000cc a day. In addition, a cup of milk a day can increase calcium intake. If you dare not drink milk, yogurt, cheese or soy milk is a good substitute.
During the pregnancy, more green leafy vegetables should be ingested. In addition to increasing fiber, promoting intestinal peristalsis and preventing constipation, folic acid contained in dark green vegetables can also prevent fetal neural tube defects. The cooked vegetables are about half a bowl, and the calories are only 25 calories, but they are very full. Therefore, if you feel that you are not full or hungry, you can eat more vegetables, and the benefits are many!
In addition to vitamins and other nutrients, don’t overlook the sugar, especially the sweeter fruit, the more sugar, the higher the calories! Therefore, fruit is not suitable for taking a meal instead of eating, so as not to cause high blood sugar and rapid weight gain. Even freshly squeezed juices should not be consumed regularly. Even if no extra sugar is added, the amount of fruit contained in it and the excessive amount of fiber may cause excessive calorie intake.
- High iron, low sodium:
Anemia often occurs during pregnancy. This is because pregnant women need to increase their blood volume. Therefore, they must strengthen their iron intake and provide enough raw materials to make red blood cells. If high blood pressure or edema occurs in the later stages of pregnancy, a low-sodium diet should be taken to reduce the retention of water in the body to slow down the symptoms of hypertension and edema.
