The body is wise.  if we give it the ingredients it needs to be well, it will.  If we give it things that hurt it, it won’t be able to function correctly.  We must remember that all organismas tend to wellness, so our task is merely to give ours what it needs and it will do the rest.  The body is nourished basically from:

1. Water.  We have to make sure to drink pure clean water in non plastic recipients and in sufficient quantity (one and a half to two liters a day).
2. Celular nutrients.  These ae basically derived from the foods we eat, so we have to watch their quality, that they are organic, non-transgenic, unprocessed, and prepared in a healthy manner.  If we lack some nutrient, we can always take a supplement.
3. Energy.  Here we can fit our thoughts, that should be positive, the emotions that need to be recognized and expressed, our spiritual practice that elevates our vibration, our capacity to let go of our problems, etc.
4. Excercice. The human body is designed to move, so being sedentay is a problem for it.  We have to walk, stretch, dance, do as many movements as possible.
