title: Nutrition, brain function and behavior.
abstract: Current food intake has been shown to directly affect neurotransmission, with resultant modification of behavior. The role of vitamin co-factors in brain function is discussed, with emphasis on changes in mood and neurological function with deficiency. The use of megadoses of vitamins for the treatment of psychiatric diseases has little scientific support at this time. Current research also does not substantiate the Feingold thesis of improvement in childhood hyperkinesis when an additive-free diet is consumed. The effects of medications used to moderate mood are related to changes in nutrient intake that in turn alters weight status. In addition, the effect of certain nutrients modifying the dose response to mood altering drugs has been discussed. Finally evidence for mood state directly affecting the capacity of the body to utilize nutrients is presented.
