Tofu provides the building materials for neurotransmitters and contains nutritional elements that promote neurotransmission, which makes it a good food for memory and concentration.

In order to increase brain activity and improve memory and concentration, it is important to ingest nutritional components that will stimulate neurotransmissions in the brain. Not only does this stimulation improve the workings of the brain, since the brain controls the workings of the entire body, a variety of nutritional components are involved. Neurotransmissions occur through the secretion of neurotransmitters such as adrenalin, noradrenalin, dopamine, serotonin, etc. There are many neurotransmitters and each one has a specific purpose. Of these, the neurotransmitter associated with memory and learning is choline.

There are also substances that supplement the functions of neurotransmitters, and of these, calcium plays a significant role. When calcium is deficient, the smooth flow of neurotransmissions becomes disrupted and the ensuing mental irritability disrupts concentration.
Although neurotransmitters flow through nerve cells, if the nerve cells themselves are not healthy, then neurotransmissions will not be smooth. Nerve cells can be revitalized by proteins and vitamin K.

Stress interferes with the normal workings of the brain. When under stress, autonomic nerve coordination is disrupted and excitation increases. Although the body uses vitamin C to produce anti-stress agents, this process requires many minerals, and of these, magnesium plays a central role.

Soybeans are rich in the nutritional components that are associated with memory and concentration. Tofu, which is made from soybeans, also contains these components.
