Definition and context
The measurable efficiency of mental processes — attention, memory, executive function, processing speed — as shaped by diet, nutrient status, and eating behaviors. What makes it nutritional psychology is treating diet and eating behavior as modifiable, bidirectional inputs to cognition: nutrition shapes cognitive performance, and cognitive states and processes in turn shape eating behavior.
See the Diet and Cognition research category in the NPRL to find more studies on the diet-cognitive relationship, and the Diet and Human Performance research category for more on how diet and performance interact.
