In this month's Food Technology (October, 2014), the feature article A Diet for a Kinder Planet lays out some of the research that indicated a link between poor nutrition and bad behavior.
It states that omega-3 fatty acids, B vitamins, zinc and tryptophan may be essential for mental balance. These are often lacking in the diets of children. Because of this, they suggest that be a cause of antisocial behavior.
The omega-3 fatty acids an important component in brain tissue (considering the 60% of the brain's composition is fat....I guess it is not bad to be called a fat head). "
In particular, the omega-3 fatty acid docasohexaenoic acid (DHA) makes up a significant proportion of nerve-cell membranes and synapse in the central nervous system.." One of the best sources of omega-3 fatty acids is fish.
The article admits that the studies to this point only demonstrate a positive correlation and do not indicate causation. This is an interesting read.
Food Technology (October, 2014)http://www.ift.org/food-technology/past-issues/2014/october/features/a_diet_for_a_kinder_planet.aspx?page=viewallA Diet for a Kinder Planet Toni Tarver | October 2014, Volume 68, No.10 Considered essential for good health, a wholesome diet and good nutrition may also help improve the behavior and mood of society at large.
Good nutrition is a prerequisite for proper development of the human body after conception, and it is considered a crucial factor in the prevention of chronic disease. It is widely accepted that cancer, cardiovascular disease, diabetes, obesity, and other manifestations of chronic inflammation can be controlled or averted with a nutritious diet. Consequently, the food and nutrition policies of the United States, the United Kingdom, Canada, and other wealthy countries have focused almost exclusively on how diet affects physical well-being, recommending proper caloric and nutrient intakes for a healthy heart and healthy teeth, bones, and weight. However, these policies make little or no reference to the human brain, which is the most complex part of the body.
The brain regulates the functioning of vital bodily organs, is the center for intelligence and emotional response, and consumes approximately 20% of the body’s caloric energy. The brain is also responsible for the expression of personality, mood, and behavior—all of which define humanity. Yet wealthy countries with diverse and extensive food and nutrition policies focused on healthy bodily functions and physical well-being have largely ignored the importance of proper brain function and behavioral well-being. As a consequence, Westernized countries such as the United States and the United Kingdom have experienced a precipitous rise in aggression, irritability, impulsivity, and other antisocial behaviors. Are these displays simply a consequence of the extensive free will enjoyed by Americans, Britons, and others, or is something else at play? A fascinating field of research suggests that depression, aggression, impulsivity, and other displays of antisocial behavior may be the result of nutrient deficiencies in the brain and that certain foods and the nutrients they contain may curtail the expression of antisocial behavior.
