We are what we eat, perhaps not always in a direct manner.
As I wrote in an earlier postings "we are all inviduals, I am not, and the Gaia hypthesis is also about us" the bacterial flora in our guts have immense effect on our wellbeing, an impact that we are only beginning to understand.
Since the development of the flora depends on the environment of the host i.e. us, and what we eat, it is not surprisingly that there are now indications that food intake affect our mental states. One report states that there is an association between food intake and the development of ADHD.
Attention deficit hyperactivity disorder; ADHD is a neurobehavioral developmental disorder. It is primarily characterized by of attentional problems and hyperactivity, with symptoms starting before seven years of age. ADHD affect about 3 to 5 percent of children globally.
The question is whether the food intake has a direct impact or indirect impact on neurology. I personally think both. I think that the gut flora is affected and shaped by the environment we create by our food, and this flora will affect us in various ways. Also the chemicals and refined sugars in modern food might affect us, although the body is an expert at expelling “shit” out of our system. And the third possible way that I can imagine right now is the actual bowel movements of the internal food organs and that this affects the nervous system. There are loads of yoga exercises that affect bowel movements.
