A recipe for
World peace:
Nutrition and social behaviour
World peace is of
universal benefit but achieving it has proved to be more elusive. One
such universal factor is nutrition.
Human beings are
part of the food chain, not independent from it. We are thus what we eat
and if we can finally accept that mind and body are not separate, a
simple explanation why food may affect behaviour is found in the
existence of the human brain, which like any other part of the body
requires nourishment to function normally. Indeed it is possible that
these changes may be altering the chemical composition of our brains.
Nutrition is a
meeting point of the physical and social worlds: the hardware and
software of life so to speak, where both are required for peaceful
behaviour. Nutrition provides the raw materials for the normal operation
of the brain and much of our social behaviour is built around eating.
Nutrition thus contains aspects of both nature and nurture. Nutrition is
widely accepted to influence long-term health; Yet we somehow manage to
de-couple that relationship from the assumption that our behaviour is
purely a matter of free will. Recently published research that
demonstrates nutrition may be a causal factor in antisocial behaviour
adds to doubts about the tenability of that assumption and suggests that
like health, our behaviour is influenced by both social and physical
factors. As the Buddha taught "Just as it is in the outer world, so it
is it in the inner world."
Crime trends in
the UK over the last 100 years show all forms of crime have risen
enormously over that period.
If changes in our
nutrition play a role in this trend, a person so affected couldn’t
normally sense a lack of essential nutrients in their brain so that
there could be potent effects on our behaviour that (unlike alcohol) act
without our knowledge.
Nutrition has
been demonstrated to significantly reduce antisocial behaviour with
various degrees of sophistication from dietary education, the
replacement of unhealthy snack foods in prisons, through to double blind
placebo controlled studies using nutritional supplements. There is also
a myriad of evidence of the role of essential nutrients in metabolic
pathways that hint at how these effects occur.
If nutrition
plays a causal role in our behaviour, then effects from nutrition would
not only have to be in force within individuals as has been demonstrated
experimentally but presumably should be capable of helping shape
patterns of social behaviour. In the case of antisocial behaviour these
changes are considerable and interestingly, there is evidence that major
changes in nutrition have occurred over the past 50 years.
Other nutrients are refined and consumed
in unprecedented quantities. Good nutrition appears to be cheap, humane
and highly effective at promoting peaceful behaviour behaviour. |
