Question: How does a person feed their nerves?
  Your body has as a self electrical current of a spark that relies on food. Just like the rest of your body, the electrical current needs food to burn so it can do its job.  Your nerves actually send off a small electrical spark to each other just to hand off a message or carry out a response for a muscle or body part(s) to move.  But the electrical current can only be produced in the body by burning the right kind of fuel.  That fuel is in health food!  Different foods fuel different body parts in the body.

Answer: Electrolytes are the right kind of food for your nerves in your body that you need to consume to stay healthy.  And you can feed your nerves, that is your electrical system in your body, with foods that contain the foods that have the nerve food of electrolytes in it.  Here are some of the electrolytes to look for in ingredients of food and water: water, sodium, potassium, calcium, magnesium, chloride, phosphorus and vitamins... Note water is considered a food to help your body feed its nerves too.
