The process of metabolizing nutrients through myriads of processes inside your body would challenge the most sophisticated computers in the world. The complexity of this coordinated action is beyond comprehension. Direct consequence of this complexity is that
it cannot be duplicated - each of us has unique biochemical "blue-print".
From digestion of food and assimilation of nutrients, to the transport, utilization and elimination, detox and immune-functions, and to the regulatory mechanisms overseeing all this - there are countless variations in the mechanism of action possible. We all need same raw materials to support life, but the specifics of the biological processes and their end products are different and unique at many points for each single individual. In other words, same input will result more or less different effect with every single person.
This is one of the reasons why generalized dietary standards - such as DRI (former RDI) for nutrient intake - for healthy intake of nutrients, are more or less different from your individual optimum. Moreover, your own optimum changes with time, activities, environment, health condition, and so on.
Is your "metabolic type" fixed?
This is what the "metabolic type" concepts overlook, when suggesting that each individual belongs to a certain metabolic type for life. Real life is, as usual, more complicated. Using a handy concept of
metabolic cross 12
with the extreme diet modes being vegan on the left vs. carnivore on the right, and raw on the top vs. cooked on the bottom, most people will do best with diets gravitating somewhat left off the center. In other words, with little of everything, but with plant foods dominant.
That is, most of healthy people will. Any metabolic imbalance - induced by poor diet, illness, or even genetic twist - can and does shift the optimum diet closer to one of the extremes. Candida infection, damaged cell membranes leaking calcium, grain sensitivity/allergy, or compromised carbohydrate metabolic pathway (enzymes metabolizing carbohydrates), for instance, would make meat based diets your more efficient energy source. Once the imbalance or disorder is corrected, optimum diet shifts toward the omnivorous section of the cross (with possible brief pull to the opposite end, as a part of the body balancing out).
But if the carbohydrate metabolic pathway works efficiently, and there is no other factors, like Candida infection, obstructing the use of carbohydrates, optimum diet for recovery from serious illnesses is very likely to be plant based. This is due to plant based foods providing, in general, wider variety of nutrients, being easier to digest, cleaner to burn and less contaminated.
Gradually, as the body heals, the optimum diet also shifts toward omnivorous (with a brief carnivore balancing flare possible).
These few examples illustrate that your individual metabolism is not cast in stone. It is both, very complex internally, and affected by a number of outside factors. The fact that you appear to be thriving on a certain diet
doesn't necessarily mean that it is your long-term optimum.
If it is closer to the extremes on the metabolic cross, chances are, it is caused by metabolic imbalance, or impaired health condition. If so, your longer term health prospects are questionable. If you find yourself toward the ends of the metabolic cross,
you want to know why you are there.
While some metabolic types are genuinely optimized for extreme diets, they are rare. On the other hand, folks with imbalances of all kinds are many, and the chances that you are among them are much greater.
How do you find out if your "best feel" diet is off due to your natural metabolic type, or due to nutritional/health imbalances? Good place to start is to have lab tests done for your nutrients (minerals and vitamins) level. It reveals the very basics of your individual biochemistry. Unless you have more specific indications, you may also consider organic acid or metabolic test, which analyses some 40 urine metabolites, and gives indications of the efficiency of a number of body's metabolic processes.R
Helloo - anyone there that actually knows what is s/he doing? Even the worn-out refuge of "benefits exceed risks" doesn't work. What happened with Hippocrates' "Do no harm"? I'm sure it requires higher level of knowledge, but even more importantly, shifting the emphasis from "treating" (read: making big money) to genuinely helping those who suffer.
