effects of certain environmental factors are often difficult
to prove scientifically. This is not only a matter of the
research approach applied: If a scientist "finds
out something negative" in specific areas, it almost always
means he has to deal with positions of financially well-hedged
parties of economic interest, which often concentrate on income
rather than on health of human beings and nature. For this
reason, it is necessary for scientists publishing in environmental
medicine, to use the word "may" disproportionately
often in their texts - even if they know that they are dealing
with rather well-documented facts.
Much can be recognized by careful selection of methodology.
In environmental medicine, influences often become visible
when specific immune parameters and stress reactions are tested. In
nutritional medicine, an area that in part can also be understood
as environmental medicine, the best possible research approach
too is the factor determining success - for instance, if
one wants to find out if and why organic food is healthier
than conventional food.
way: "organic" is not just
a matter of nutrition. It is also a very explosive ethical, climate and spirituality relevant question.
