T he human body is in a constant state of repair, rebuilding, and regeneration. As cells die or become injured they are replaced with new cells. The tools used by the body to perform this feat are provided by the food we eat and the body’s ability to break down that food into molecules small enough to be used.
The need to maintain self and homeostasis is so critical that the body will even catabolize from itself in order to preserve critical functions. It also has the ability to convert certain nutrients into others that are necessary at that moment. This isn’t possible for all nutrients, scientists have designated those nutrients that the body can’t convert as “essential” because of the need to get them from the food that we eat.
Nutrients are not only used for rebuilding and repairing but also have the ability to protect the body from disease and injury.
Many of modern society’s health problems are the result of weaknesses in the body’s physiological foundations brought on by poor nutrition and lifestyle – either the body isn’t provided with the proper nutrients in the food that is consumed, or our poor nutrition and/or lifestyle doesn’t allow the body to properly break down the food so that the body can utilize the nutrients provided.
