Part 2 of 3 (Part 1) (Part 3)
     Part 1 of this series on metabolic bio typing introduced the idea that whether a given food or a particular diet is good for you or bad for you is a matter of your genes -- not whim, appetite, preference, philosophy, belief or even "expert" opinion.
    It is important to realize that the idea of metabolic bio typing is not new. The roots of the concept of metabolic individuality can be traced to antiquity. The 5,000 year old East Indian system of medicine known as Ayurveda was based on the interaction of the 5 elements and the 7 energy centers in the individual and primary treatment addressed one's dosha (one's Metabolic Bio Type) before it addressed the symptom or disease.
    Similarly, the ancient system of Chinese medicine recognized 5 elemental, constitutional types. Diagnosis and treatment in ancient Egyptian medicine was based on the 7 organ systems in the body. Greek physicians were concerned, as Hippocrates stated, with the patient who has the disease instead of the disease that has the patient, and evaluated the 4 humors (liver-bile Metabolic Bio Types). The ancient Roman philosopher Lucretius is attributed with the saying, "One man's meat is another man's poison."
The modern background of metabolic bio typing
    In modern times, there have been some well-known and many not so well-known medical researchers who recognized the value of addressing biochemical individuality. In 1919, Frances Pottenger, M.D., published his Symptoms Of Visceral Disease, where he established the autonomic nervous system as the basis of metabolic individuality and correlated the influence of various nutrients on the autonomic nervous system.
     Dr. W.H. Sheldon, in the '40's, published his famous Varieties Of Human Physique, providing photographic illustrations of his somatotypes (ectomorph, endomorph and mesomorph Metabolic Bio Types).
      In the '50's, Dr. Melvin Page and Dr. Henry Bieler concurrently developed concepts of endocrine types and their relationship to various foods. Dr. George Watson, also in the '50's, in his astounding book, Nutrition And The Mind, published his research on the variable influences of oxidation (glycolysis, beta oxidation, citric acid cycle) in different individuals he classified as fast, mixed or slow oxidizers.
     In 1956, the noted biochemist, Dr. Roger Williams, published his genetotrophic theory on biochemical individuality, based on his research which suggested that every human being has, because of his genetic makeup, distinctive nutritional needs that must be met in order to achieve optimum health and well-being. Dr. Royal Lee's extensive writings in the 50's and 60's correlated nutritional influences of the autonomic and endocrine systems.
     Dr. Emanuel Revici, in the '60's, recognized the critical necessity to address biochemical individuality and devoted his life's work to the development of an entirely new system of medicine based upon the variances between individuals in their catabolic and anabolic influences.
     Dr. James D'Adamo, in the '70's, put forth a system of individual classification based upon ABO blood types. In the mid '70's, Dr. William D. Kelley met Dr. Roger William's call for "metabolic profiling" by becoming the first to apply William's concept of nutritional individuality to computer science in identifying the autonomic types, sympathetic, balanced and parasympathetic.
     Further efforts to address metabolic individuality can be seen in current works of numerous other pioneers. Among the more recent who have joined the ranks are Dr. Elliot Abravanel, Dr. Paul Eck, Dr. David Watts, Dr. Rudolph Wiley, and the insightful founder of Nutri-Spec, Dr. Guy Schenker, to name a few.
What exactly is metabolic bio typing and why is it important?
    metabolic bio typing analyzes, evaluates, and interprets objective physiological and biochemical indicators along with symptomatology in order to define one's Metabolic Bio Type -- the specific, individualized, genetically-based patterns of biochemical metabolic individuality that dictate one's physiological and neurological "design limits" and requirements for nutritional substances.
    The food that we eat is intended as the "fuel" for our body's cells, our engines of metabolism. Our cells in turn convert the fuel to energy to be used in all the life-supporting processes of metabolism that keep us alive and healthy. But like any engine, our body needs a certain kind of fuel to function optimally. A gasoline engine requires gasoline for fuel. A diesel engine is designed to run on diesel for fuel. But try to run a gas engine on diesel or a diesel engine on gas and not only will the energy output be deficient, but using the wrong fuel for the engine will cause real problems for the engine itself.
     Similarly, our bodies have genetically-based requirements for specific kinds of foods and balances of nutrients in order to produce optimal energy and function in a state of optimal health. If we meet these "design requirements," we can expect to be healthy, energetic, fit and trim.
    Failure to obtain on a regular basis the kinds of foods our body's are designed to utilize will initially produce sub-clinical health complaints such as fatigue, aches and pains, headaches, indigestion, weight gain, constipation, rashes, dry skin, low blood sugar, etc.
     Long-term deficiency of the right foods for the Metabolic Bio Type will lead to degenerative conditions like asthma, cardiovascular disease, cancer, diabetes, arthritis, etc. In other words, it's not just that the Eskimos can eat up to 10 pounds of meat and huge amounts of fat and almost no carbohydrate, they need to eat that way in order to be healthy because that's what their metabolisms are genetically programmed to utilize as fuel. Similarly, each of us has very specific requirements for nutrients that must be met in order to obtain and maintain good health, energy and well-being for a lifetime.
     Without typing metabolically, there is no way to discern one's "medicine" from one's "poison", and  to know how nutrients behave in one person as opposed to another
