Lecithin Consumption Increases Acetylcholine Concentrations in Rat Brain and Adrenal Gland

Abstract
Consumption of a single meal containing lecithin, the major source of choline occurring naturally in the diet, increased the concentrations of choline and acetylcholine in rat brain and adrenal gland. Hence, the concentration of acetylcholine in the tissues may normally be under direct, short-term nutritional control.
