Unlock The Real Power Of Nutrition And Biochemical Individuality!

Each person has a specific response to exercise and nutrition, but we are still unclear on our own responses. Find out what works and what doesn't.

Article Summary:
  • Information on nutrition has been based on how nutrition affects the 'average' person.
  • Training programs are catered to the individual and nutrition programs should be too.
  • One should read the signs their body sends them when eating different types of food.

Nutrition And Biochemical Individuality

All of us have bodies that are built in different ways, we all look different, we all act different, it's a true fact that we are all unique. This biochemical individuality allows us to differentiate from all the different body types we see such as endurance body types to sports men and women and all the way up to rugby players, American footballers and bodybuilders.

Each person has a specific response to the exercise type and the nutrition they consume, we are all aware of the exercise type, but we are still unclear on our own responses to diet and nutrition. Find out how some diet recommendations haven't worked for you and have a better idea on which ones will.

In current day training methodology we employ many forms of assessment when we meet a new client for the first time as well as periodically throughout their training program.

This allows us to record individual differences and variances within the population as a whole due to genetic and environmental influences. A periodical assessment evaluates your client's responses to your training program and allows you to determine what changes are necessary for continued improvement.

Thus we treat our clients on an individual level in regards to physical and physiological responses to exercise but not to a great degree before on a nutritional basis. This is a poor attitude to the importance and vast benefit available from nutrition and I still see many trainers and magazines lump everybody in the same basket and not appreciate the biochemical individuality that exists between us.

I hope this article brings some sense to the fact that we now appreciate the biochemical differences of individuals and monitor them accordingly, both from a nutritional standpoint as well as a physical one. If different people have different physical attributes, it makes sense then, that their nutritional requirements and nutritional responses will also be different.

Nutrition For The Individual

      The concept of biochemical individuality is not a new one in fact, at least not in the medical world. The first theory of biochemical individuality was introduced by an English physician, Sir Archibald Garrod in 1908


      even though his works weren't published until the year after.

Who Is Sir Archiblad Garrod?
Sir Archibald Edward Garrod was an English physician who pioneered the field of inborn errors of metabolism. He was born on November 25, 1857, in London, and died on March 28, 1936, in Cambridge.

      In the past, nutrition has largely been based on what the food properties were and how much that would benefit the population as a whole, rather than on how specific that nutrient was for any given individual.

Now with further research since Sir Archibald Garrod's ground breaking work, we now know that even diseases such as phenylketonuria, an autosomal genetic disorder, can be effectively treated and cured. Phenylketonuria is characterized by an enzyme deficiency2 and a diet low in phenylalanine and high in tyrosine provides a great treatment, especially as there is no cure and damage done is irreversible.3

In even more recent works we see even more effective treatment on health from the power of nutrition from William Wolcott's new book 'The Metabolic Typing Diet.' A conglomerate of health practitioners such as nutritionists, physicians, physiologist's and even psychologists collate evidence on how foods are playing a massive role on their specific area's of research.

Science from over 30 years ago4 has been assembled and applied to human subjects which is the common denominator of all our work regardless of your area of study; and as we are not all working with the exact same person our guiding principle must be to the individual client and their bodily relationship to food and specific nutrients, not the other way round.

For some time now we have been using physical systems to train and coach the clients and athletes we work with. Over time we have learned to refine and adapt our training principles to the individual rather than the old body building approach of 10 - 12 reps repeated 3 times for the masses - the industry standard some 10 years ago.

I am happy to report I do not see too much of this over simplified approach being used on the ever growing health club membership. The works of Paul Chek, Michael Boyle, Gary Gray and Alwyn Cosgrove to name but a few, are raising the level considerably in this field of human physiology. What is physiology or physiological exactly?

Assessing The Individual

      Physiological - Being in accord with or characteristic of the normal functioning of a living organism.


      I have included this to illustrate why we need a specific individual score rather than a general sweeping statement. After reading this quote who then is normal? Is it you or is it me? Is it again a third person and why them?

We could be talking about physical height, organ efficiency, jump height or nutritional requirements the list is endless and any of these parameters mentioned will also differ between individuals not too mention the countless hundred not quoted here.

Every single human parameter can also change over time at any time depending upon the demand incurred from Birth to Death. Hans Selye describes that individuals not only have different size stress organs, but each person has their own tolerance to stressors (a stressor such as floor prospecting for trainers) and that each person has different stress levels and stress responses; what might very well be a stressful situation for one person, might not be for another individual.6

Who Was Hans Selye?
Hans Hugo Bruno Selye, CC was a Canadian endocrinologist of Austro-Hungarian origin and Hungarian ethnicity. Selye did much important factual work on the hypothetical non-specific response of the organism to stressors. While he did not recognize all of the many aspects of glucocorticoids, Selye was aware of this response on their role. Some commentators considered him the first to demonstrate the existence of biological stress.

      Everyone has their own unique genetic imprint and individual environment in which they live; they greatly influence the specific foods each and every person requires. Some of these influences can be seen on the table below to illustrate what stressors and unique environments I am talking about.

This table also serves to show that the body is in a constant state of flux7 and thus repeat assessments and regular follow ups are essential for best results.

Table 1:

Physiological Challenges Environment Genetics
Growth Work Pressure Male
Weight Loss New Job Female
Fat Loss Relationships Child
Strength Family Older Population
Endurance Money Disablilities
Power Altitude Hereditary Disease
Regeneration/Reovery Temperature Hereditary Development
Prenancy Pollution/Chemical Metabolism
Adaptation Experience Indicidual Organ Size

It is good practice to follow up on a client's nutritional recommendations every couple of weeks; this is where the '7 day food diary' serves as a useful tool. A re-assessment of a client's individual needs can be performed every quarter or less depending upon what new or intensifying stressors exists in their specific environment.

Reference to the above table can be helpful if you suspect or detect new stressors entering their life and after a week or two of exposure - retest and measure accordingly. If this is something new to you and difficult to comprehend I suggest looking for nutritional or educational courses from previous mentioned contributors such as Paul Chek's HLC course or read books from authors such as Joseph Mercola8 as well as William Wolcott and Trish Fahey4 to improve your knowledge and unlock the real power of nutrition.

How Food Can Lead To Poor Health

      With this new knowledge of each of us possessing our own unique individual biochemical make up, we now know



      • Any food or nutrient that works well for one person may have no effect on a second and may even make a third person worse
      • Any food or nutrient can have virtually opposite biochemical influences in different people
      • This is the concept that lies in the heart of metabolic typing
      • The effects of nutrition are cumulative, the more you ingest the stronger the effect

This last statement is extremely important to understand as foods to avoid for your unique biochemistry are essential knowledge in my book, there are several foods that are not beneficial to any human and these are to be reduced if optimum health and fitness is to be achieved or greater recovery from an illness or degenerative condition.

Thus a reduction in health and performance can come from a limited intake of essential nutrients as well as consumption of bad foods. When un-essential foods are continually ingested, poor nutrition occurs, this is responsible for most if not all of the weird and wonderful diseases we see in our clients and in the world today.4,8,9

Poor nutrition also occurs when we ingest incompatible chemicals/ foods, such as alcohol, drugs, trans-fats etc. The result on both accounts is a declining spiral of events taking place starting with nagging colds or simple ailments to begin with, leading down to chronic disease .

Nutrition and food choices suddenly become more important when considering this . As you become more and more imbalanced your bodily functions start to get progressively worse until one system fails completely.

As each person suffers with their own specific depletion this would answer why some people can be suffering from more than one ailment at a time and why most current leading health practitioners cannot explain them.

It is easy to forget that what we eat is directed into our blood stream and/ or organs and from there, is delivered to every cell in our bodies, approx 3-6 times a day, every day; this accounts to 21 - 42 times a week!

The impact of nutrition therefore is massive on our health and performance, in fact for successful function the quality, rate and amount of food4,9 at any given time must be considered. This must bring the use of non-organic products into question as these contain many chemicals not designed for human biochemistry to metabolize or are synthesized in a way our bodies don't recognize; which when left unchecked, can also affect the very important processes that run on a daily basis. These are:

      • Digestion
      • Transport
      • Respiration
      • Synthesis
      • Regulation
      • Growth
      • Reproduction10

Without this knowledge it is very likely that most of you are malnourished in one system or more. This can be detected by energy dips, headaches, cravings, digestive disorders or other nagging ailments as well as excess body fat. Where else are you going to store toxins or excess nutrients not required?

What are the symptoms of a hang over? That is your body (specific organs actually) telling you its reacting to your previous night of alcoholic consumption; it repeats this message every time it happens. This is your own internal doctor talking, your own biochemistry responding to the nutrients or lack of being metabolized at that time.

Malnourishment Can Be Detected By Energy Dips, Headaches, Cravings, Digestive Disorders, Or Other Nagging Ailments.

If you feel well and have good energy consistently then it's a sure sign you are eating right for your specific individual needs; if not, adopt some changes. Increase your skill as a trainer, coach or nutritionist and seek out these references as it will bring you and your clients towards the levels of health of fitness that we and they all yearn for.
