The importance of biochemical factors and nutritional patterns of the security officer can help enhance security operations. Nutritional deficiencies can be a factor in concentration, awareness, alertness, fatigue, and emotional restraint. Studies of prison inmates have shown the effectiveness of a low refined-carbohydrate diet on improved behavior patterns. Interactions between drugs and alcohol and nutrients in the body hinder nutrient absorption and metabolic functions and increase nutrient requirements and excretion. Since billions of dollars are spent on high technology equipment and sophisticated security devices, security professionals may also want to take a closer look at the ecology of the persons who build, maintain, transport, and operate these systems. The effectiveness of security is greatly affected by the behavior of people. Nutrition and toxicology are now generally accepted as undisputed factors in behavior, even by the mental health and medical professions. The window of indifference can be subject to many variables, both from inside and outside the security person.
