Nutritional value of pig's trotters:
The collagen in pig's trotters is composed of numerous amino acids, and one of every three amino acids is glycine. After eating pig trotters, collagen can be digested into a large amount of glycine acid in the human small intestine. These acids can not only participate in the synthesis of collagen in the human body, but also act as a central nervous system inhibitory transmitter in brain cells. Can produce a sedative effect on the central nervous system.
Eating pig trotters can help reduce excessive excitement of the central nervous system, and can also improve anxiety, neurasthenia, and insomnia. In addition, glycine also exists in the interneurons of the human spinal cord. When the interneurons are damaged, glycine supply is necessary. Glycine can inhibit the excitability of spinal motor neurons and interneurons, and can cause the superization of spinal cord neurons.
Eating pig trotters rich in glycine has a positive effect on adjusting the functional activity of normal subneurons. Since the glycine contained in pig's trotters has a sedative effect on the central nervous system, people have also found that some people often have calf cramps or numbness, as well as spasms caused by certain drugs. Regular consumption of pig's trotters soup can also have a certain therapeutic and relief effect.
