Chiropractors are the specialists that look for physical interferences in the nervous system and remove them. These blocks to proper nerve transmission are caused by spinal misalignments called subluxations. Unfortunately, the common of the public do not know this because the general knowledge is that chiropractors are back pain doctors.
Everyone knows that if the spinal cord is severed, all function below that level is lost because there is no communication message going with the brain. However, in the case where there is loss of only some communication, most people accept the resulting loss of function as being normal and often will live with that loss as long as there is no pain or very little pain.
Your nervous system explained briefly and is kept healthy by providing it with adequate nutrition, and by keeping it free of interference. It is like a network of wires that take information around the body at very high speed using neuro-transmitters. The wires must be in good repair, so we need good fats to maintain the sheath that covers the nerve (myelin sheath). Here Omega 3 fatty acids are of importance and can be found in wild salmon, flax seeds, pumpkin seeds, and walnuts. Nervous system controls all the body functions.
