It should be evident from the discussion that while a substantial amount of evidence can now be

As will be described below, these variations often cause parallel changes in the levels of these amino acids within the monoaminergic neurons, and thereby may influence both neurotransmitter synthesis and even central neurotransmission (12).

,Allgemeines, Häufigkeit, Ausbreitung,ry avoidance are reliably found with diets that: 1, have a protein content outside the 15–35% range, 2, contain an excess of one or more amino acids, 3, are devoid of one or more amino acids, or 4, induce an amino acid imbalance. The food intake depression that occurs with amino acid imbalance will be the focus of the studies to be discussed here.
