The main focus of the film is a handful of people who were able to turn their lives around using nutrition. These were not marginal people who only had to improve a little to function. A few lost portions of their lives to the pharmaceutical industry's treatment of their mental illness. One person spent time so heavily medicated that she would sit in a chair and drool. If she fell out of the chair, someone would pick her up and put her back in the chair. That was her life.
Using sound nutrition, everyone involved in the film was able to turn their lives around and become normal, functioning members of society, throwing their meds in the trash in the process. The person mentioned above went on to have three more children and is healthy and happy.
Nothing about the film is bad, but it is a little short and could have stood to get more in depth. For those wanting more information on the subject, I recommend the book "Food & Behavior: A Natural Connection," by Barbara Reed Stitt.
One thing I found interesting in the film was the segment on Roger Williams and biochemical individuality. This was a helpful look at why some people may require more micronutrients than others. What Williams found was that intestinal disorders such as leaky gut syndrome in children stopped them from absorbing some micronutrients.
You have to keep in mind that America is running over with food. It's not running over with nutrition. Over farmed land is producing stuff to put in our mouths, it's not feeding our bodies or our brains. It only compounds the problem if people aren't properly absorbing what little nutrition is actually in our foods. Making and taking vitamins is not necessarily the answer to this problem, either.
One theory presented both in the film and in Stitt's "Food & Behavior," is that there is a host of sub-clinical diseases going on that is affecting mental health. For example, while few people have full-blown pellagra anymore -- a vitamin deficiency disease -- there may be a large number of people suffering from sub-clinical pellagra. Since a symptom of pellagra is dementia, someone suffering it may be giving a psychotropic drug (treat the symptom), when the root cause of the problem was simply a vitamin B3 deficiency.
In some way, we have to change the financial rewards in the medical industry to producing results, not selling pills, or treating sub-clinical pellagra by drugging people so hard they can only sit in a chair and drool will never change. The sad fact is, telling people to eat right is not profitable. We need people to get paid when they get people back to being fully functioning, and financially penalized when they sell pills.
Sadly, too many people in America benefit from the way things are now to really make meaningful changes. Because of this, as I always say, "when it all comes crashing down around us, we all had a hand in it!"
