Peering Inside the Brain

Peering Inside the Brain

During one of my classes while I was in graduate school, a friend and fellow student leaned over to me and said something to the effect of "the only thing that makes sense to me is health." I didn't think too terribly much about his statement at the time, but the more I reflected on it, the more I was intrigued by both the simplicity and profundity of his assertion.

Throughout my studies in philosophy and theology, I found myself increasingly unsure of many of the tenants and belief systems that were proposed.  I felt as Descartes once did in the sense that I began questioning everything that I had been taught and supposedly “knew”.  I began asking “Is there anything I could be sure of beyond all reasonable doubt?”  My thoughts kept percolating and continue to this day, but one of the reasons I got more involved with brain health is due to the simple fact that it made sense to me.  I “knew” on an intuitive and experiencial level that what I consumed on a daily basis had a direct impact on how I felt throughout the day and even the kinds of thoughts I was having.  The neurochemical basis of my awareness and consciousness seemed relatively self-evident.

The idea that health makes sense is primarily pragmatic and experiential.  You can test out your hypotheses on yourself.  If you eat, smoke, or drink something, you can usually feel the effects fairly rapidly.  While some brain nutrients and cognitive enhancers may take some time to see any noticeable effects, at some point you are able to begin making assessments on your assumptions and experimentation.  Essentially we can ask ourselves, “How do I feel?”  and “What kind of thoughts am I having?”

Here in south florida where I live, one of the places I frequent quite often is Tropical Smoothie Cafe.  Their motto is “Eat better- Feel better” and my experience in matters pertaining to brain health could not express things any better.  What we consume has a dramatic impact on how we feel and how our bodies react to the immediate environment.  If we eat low quality foods, our states of mind and how we feel can be dramatically effected by these seemingly simple decisions we make daily.

My research into depression and attention deficit disorders has further convinced me that the quality of our nutritional intake on a day to day basis can effect how we see the world around us and virtually all of our perceptions.  I know personally that when I dodn’t eat reasonably healthy meals or get enough sleep, I feel lethargic throughout the day and in basically a miserable mood.  However, when I eat right and get a good night’s rest, I am much more upbeat and full of energy.

How and what we eat impacts how and what we think.  Not only the quality of our thoughts are effected, but also their overall tonality.  Our thoughts seem to carry with them a feeling dimension to them and the connections between our thoughts and emotions are intimately in a relationship with one another.
