How many months does the fetal brain develop?

We all know that a baby is formed from the development of a small embryo. As time goes by, the baby grows up day by day. But in fact, most of us don't know at which stage of pregnancy a baby's brain develops. The link of growing and developing human brain is very important. So, at what months does the fetus' brain grow and develop?

At what month does the fetus' brain grow and develop?

Pregnancy at eight weeks. From the 19th day after pregnancy, the nervous system of the test tube embryo begins to develop rapidly, until around the 26th day it begins to close from the bottom and expands downward to form spinal nerves. In other words, the growth of the fetus's head begins to form 4 weeks after fertilization, and from the 8th week of pregnancy, the fetus already has a basic prototype. Although it is still a little far from being fully formed, at this time it can be officially called a fetus, not a "test tube embryo." Twenty weeks of pregnancy. Around 20 weeks of pregnancy, the fetus's hearing, vision and other central nervous systems begin to develop. After 20 weeks, the growth and development of the brain nerves will become more and more complex. This stage is also the beginning of fetal movement. It is also the most effective stage for the interaction between the mother and the fetus. It is most suitable for giving the fetus good stimulation, so that it can form a good neural circuit and help the brain nerves gradually develop in a good direction. Thirty weeks of pregnancy. The basic development of the fetus's head is fully formed around the fourth month of pregnancy, but the neurons that control the development of the central nervous system will not stop functioning, but will continue to develop neurotransmitters in a tree-like structure until about 3 years after birth, and may continue to develop even into puberty. The stimulation and development of these synapses are even more important in establishing many of the fetus' future abilities (vision, hearing, touch, taste, smell, vestibular sense, motor sense, etc.).

Three standards for nutritional supplementation during pregnancy:

Generally speaking, the development of the fetus's brain mainly depends on pregnancy. Between the third month and the sixth month, it will develop faster. The late stage of pregnancy is a critical period for the baby's brain development! At this time, you can eat some dried fruits, which are beneficial to the growth and development of the fetus's head. Mothers can take some DHA health products. It's time to start stocking up on baby formula. You should buy formula rich in lactoferrin and DHA, which is good for the baby's brain development, and is not prone to getting angry, so it's safe to drink. It is strongly recommended to eat more foods rich in oleic acid, lecithin, and iodine.

1. Comprehensive standards: The human brain is mainly composed of nutrients such as long-chain fatty acids, proteins, carbohydrates, vitamins (B, C, E) and calcium. Nutritional intake must be comprehensive. Nutrition experts recommend that it is best to consume 40 kinds of food every day, and at least 14 kinds.

2. Balance principle: Scientific research has confirmed that when fat intake accounts for 30% of the body's total energy, protein accounts for 15%, and carbohydrates account for about 55%, the body will achieve a good balance. As far as human fat is concerned, it is best to maintain a balance of saturated fat, polyunsaturated fat and monounsaturated fat, that is, a ratio of 1:1:1. For the two mineral elements calcium and phosphorus, the best ratio is 2:1. However, it is difficult to optimize your daily life in this way. As long as you eat a wide range of foods and are not picky about food, that will be enough.

3. Natural principle: that is, select the ingredients that have outstanding contributions to the intelligence of the fetus from the natural ingredients in life, and use them as the main body of the three meals structure.
