Nutritional therapeutic treatment methods for abnormal behavior have been used for many years. Deficiencies in the body that relate to behavior include: vitamins, minerals, amino acids, enzymes, and endocrine functions, as well as many neurotransmitter malfunctions. Environmental toxins, heavy metals, chemicals, non-foods, and contaminated foods can, and do affect behavior. Violent, aggressive, depressive, and abnormal behavior can result when biochemical and biological imbalances, including those caused by starvation, send...an otherwise-healthy person into maximum mental "overload." When unusual changes in behavior are observed, including emotional instability and suicidal tendencies; with proper therapeutic nutrients and nutrition carefully applied, the affected individuals' mental stability would receive incredible support for self-recovery.
