Stages of Nutrition: What's Next?
A good diet is the first step to ensuring
our bodies receive the proper balance of
nutrients necessary for optimal health.
Diet consists of all the foods, liquids, and
supplements that we consume daily.

DIET
The goal of a good diet is to provide both
nutrient density and nutrient diversity.
Nutrient density refers to consuming foods
that contain nutrients, such as vitamin C
or a mineral such as calcium, in amounts
that are conducive to optimizing health.
Many modern, processed foods have
been depleted of their nutrient density as
a means of extending shelf life, or simply
due to the effects of the processing itself.
DIGESTION
Digestion begins with chewing and
includes the action of acids and enzymes.
It is the process by which complex foods
are broken down into simple substances
that the body can use for energy and
support of cells and tissues. For instance,
lipids, proteins, and carbohydrates are
broken into fatty acid, amino acid, and
simple sugar building blocks, respectively.
DIGESTION
ABSORPTION
Absorption is the process by which the products of digestion, simple sugars, amino acids and fatty acids pass through the lining of the intestinal wall and are taken directly into the bloodstream. Adequate amounts of nutrients may be eaten and digested but may still be unavailable to the cells due to poor absorbability. Poor absorbability can come from excess mucus along the intestinal walls, allergies or excesses, the condition of the capillaries feeding the stomach walls or to the cell sites, the amount of uneliminated waste at the cellular level, and the binding effect particular foods have on some nutrients which cause them to be excreted.

CIRCULATION
CIRCULATION
Transporting the absorbed nutrients to
each cell of the body is the role of the
circulatory system. We may be eating
properly, digesting properly and absorbing
nutrients properly, but if our circulation is
impaired, nutrients may not reach their
cellular destinations.

ASSIMILATION
Assimilation is the delicate process by which nutrients are
passed through the membranes which surround each living cell. For the body’s cells to grow, repair, and rebuild themselves, proper assimilation is essential. For this process to take place, cells — especially their membranes
— must be healthy. It is also essential that the
rate of cell repair meets or exceeds the rate of
deterioration. Proper assimilation of nutrients is
required for cellular repair.
CLOSER LOOK
ELIMINATION
It is important to excrete daily. What goes in must come out. It is felt by many doctors that one of the chief causes of human illness is due to autointoxication – the poisoning of the human body by waste materials absorbed by the villi (intestinal lining) into the bloodstream, and by the improper release of metabolic waste from the tissues. Re-absorption of waste affect all levels of nutrition and organ functioning, and a system which is overloaded fails to have sufficient energies for maintaining optimal health as it should, and degeneration begins to occur.
