What is an essential nutrient?
A nutrient is an essential nutrient if and only if:
Cannot be manufactured by the body.
Must be taken in from outside (food / supplement) sources.
Is essential to human health.
Deficiency disease inevitably results, over time, if an essential nutrient is eliminated from diet.
Through his decades of research, Dr. Joel Wallach uncovered the following 3 facts:
Fact#1 Every person needs 90 nutrients in order to survive
60 Minerals 16 Vitamins 12 Amino Acids 2-3 Fatty Acids
these are substances that are required for normal body function because they are not produced by the body and must be included in your diet. But even when we eat healthy, even organic, we may still not be covered. Why? Because... →
Fact#2 We are not what we eat, we are what we absorb
Digestion and absorption is important. We absorb nutrients best from organic sources vs. inorganic sources. Huh? Organic sources are plant-based sources, as in when the plant sucks up the nutrients from the soil. Inorganic sources are the soil, or rock or clay, we are not made to digest inorganic materials. So iron form the ground is not readily available for the body to absorb but iron in, say, spinach, is. We need to eat plants that have sucked up the minerals from the ground. We don’t eat dirt so why is eating healthy not enough? Lets look at fact #3
“To receive the same amount of iron you used to get from one apple in 1950, by 1998 you had to eat 26 apples; today  you have to eat 36”
Plants can make vitamins but they cannot make minerals. If the minerals are not in the soil, they will not be in the plant.
We aren't saying don't eat naturally but just beware of not being able to get what you need from food alone. This means we must supplement our diets with the nutrients we lack in order to keep our body healthy.
Ok, lets go to the vitamin store and pick up some supplements. A good multi-vitamin is about $20, right? Well the average multi-vitamin has about 20 to 25 nutrients, and the typical nutritional supplement is only 8 -12% absorbable because it's much less expensive to use inorganic materials. Also, when you are taking one supplement at a time, you don't know the right combination for your body to best absorb what you are taking. You couldn't know the right balance of "co-factors".
We need all 90 nutrients just for our bodies to survive and to be deficient in even one (1) could lead to disease* (much like Scurvy is a disease resulting from a lack of vitamin C), which a healthy body is whole point here, right?

Where do we start?
Dr. Wallach's three Steps to Health
Clean up your diet. Eat the foods that maximize absorption and avoid the foods that hinder digestion
Identify the category! (see 4 categories). Use the self-evaluation to identify what system is breaking down
Use the appropriate pack and dose! Give your body the nutrition it uses to rebuild / repair that tissue / system
