For sports people genetic tests should be the natural base to evaluate how much of their potential they are exploiting.
Many sports people are convinced that adequate training combined with correct nutrition (and here we could open a bible of considerations) permit them to achieve the best performances.
However before an allergy there can be an adverse reaction to a food which then becomes an intolerance, but even sooner an adverse reaction is then a reduction in absorption of nutrients, so basically many people have "correct" nutrition that due to different reasons (intestine, genetic predisposition, over feeding) doesn't let them use the 100% of proteins, vitamins etc.etc).
On this basis if you accept this concept the first thing to test is the engine, is the "burning efficiency" of the engine working well and checking if the fuel used is the best for that specific engine.
So the first easy test to offer is the intolerances one (TIAMI 180 but if the analysed subject is not in particular a food explorer that loves to test and eat anything the TIAMI 90 is more than enough). TIAMI is FOOD INTOLERANCE TEST IMMUNOENZYMATIC METHOD in a Italian TEST INTOLLERANZE ALIMENTARI METODO IMMUNOENZIMATICO (TIAMI).
TIAMI 90 crossed with a food weekly journal allows for a clear picture of how much food energy is being exploited in the patient.
TIAMI test offers as well the possibility to evaluate intestine wellness 'cause if the patient is eating correct food in terms of tolerance but complains about some problem with intestine (abdominal swelling, difficult or too easy evacuation, acne, excessive sweating, etc.etc) we can presume that there is a dysbiosis in progress that causes an inflammation .
