Pregnant women must know to eat fish, common sense

Denmark researchers recently approved study found that pregnant women eat fish more pregnancies at term, the greater the likelihood, at birth, babies are generally more health, more babies than spirit.
　　
Sitantengsi-Serum Institute in Copenhagen, researchers compared the 8,000 diet of pregnant women, asked how often they eat fish during pregnancy, and the fish is eating hot food after cooking, also in Sha Lazhong eating cold food or fish oil additive. Found that pregnant women who regularly eat fish appear premature and likely to give birth to lighter weight infants well below those usually do not eat fish or a small fish of pregnant women. The survey also found that, ate fish once a week, you can never eat fish possibility of preterm birth in pregnant women from 7.1% per cent.

Researchers infer that fish is good for pregnant women, because it is rich in omega-3 fatty acids, this substance has to extend the effectiveness of pregnancy, the prevention of preterm birth, can effectively increase the weight of babies at birth.
　　
Denmark scholars of this and similar studies have made similar conclusions, namely food fish can increase the likelihood term pregnancy. In fact, is rich in fatty fish such as salmon, herring, tuna in addition to benefits for pregnant women, and treatment of depression, such as inhibition of prostate cancer cell growth.
　　
Denmark scholar of the research results will be published in the latest issue of the United Kingdom Journal of medicine.
　　
Finding 1: eating the babies of pregnant women how smart
　　
Fish rich in amino, lecithin, potassium, calcium, zinc, and other trace elements, which is necessary for fetal development material, especially the nervous system. Survey shows that pregnant women eat more fish conducive to fetal development, especially the brain and nervous system, that born babies particularly clever. But the increasingly serious environmental pollution problems, if mothers worry about contaminants in fish to some negative impact fetal development. About researchers specifically to eat fish containing mercury during pregnancy the mother and child care investigation. To understand the impact of mercury pollution of heavy metals on children\'s intellectual development, researchers in six kinds of neural development indicators for research.
　　
Research data show, locals 10-20 times higher than the average mercury content in the body. But on the child\'s cognitive, language, reading, math, Visual, educational resilience, but no significant negative impact. Researchers stressed that more fish absolute good. So as long as the note body health and standard of heavy metal content, many parents should encourage pregnant women and children to eat more fish, children will be more clever.
　　
Environmental scientists have pointed out the unique problem of not eating fish contaminated by heavy metals, industrial waste water, waste and other pollutants resulting from deposition of chemicals in fish, will enable consumption to the nerve, diseases of the immune system, such a fish contamination problem is more worthy of attention. Therefore, when buying fish, best buy live fish, second, we must look at the origin, far from the industrial zone of fish, less polluting substances in the body.

Special Recommendation: nutrition during pregnancy to fill in \"the blade\" on

Finding 2: beneficial to eat fish during pregnancy fetal brain development

Pregnant women eat fish, enabling fetal brain development, this is a nutritionist in China and abroad in recent years have affirmed. Japan children\'s IQ is higher than that of children in Europe and America, according to the research, it is because Japan children like to eat fish. Scientists through research and testing, the mystery is that because fish contains an important substance--DHA (or 22 carbon six acid), which plays an important role in the formation of brain cell membranes.

According to research indicates that, actually Dang fertilized eggs began split cell Shi, DHA on began imposed effect has, fetal by placenta from maternal in the get DHA, turn effect fetal of growth development, if maternal missing DHA, is formation fetal brain cell film of Phospholipid mass also insufficient, to fetal brain of formation and development brings bad effect, even caused abortion or health Xia brain cell number less of congenital mentally handicapped baby. Therefore, nutritionists believe that health and a healthy and smart babies, is the wish of each pair of parents, women during pregnancy, you should eat more fish to absorb enough DHA, to meet the needs of growth and development of the fetus.

So, eat other foods not to eat fish is it can get DHA? Very few scientists believe that other animals and plants containing such substances. But the substance also foods you can eat some highly unsaturated fatty acids, such as soybeans, peanuts, Sesame, walnut, converted in the liver, but it is better to eat fish is more direct and timely, and effective.

According to studies, both need a considerable amount of DHA in pregnant women to maintain their own brain cell function, and large supply of fetal, so the requirement is more than most people, so experts believe that pregnant women should eat at least one or two times in under a week fish or shellfish. In order for the good development of the brain of the fetus, a robust and high IQ better baby, it is proposed that pregnant women to eat more fish, even if the baby was born after weaning, is advised to use a fish for food and feed baby fertility.
