Each class has distinct affects on cognitive functioning and health. [4] Omega-3 polyunsaturated fatty acids are especially significant as they are critical cell membrane and structural components of the brain. [1] [4] [12] Cholesterol is an unsaturated alcohol commonly found in eggs, meat, and dairy.
Poor diet in early childhood affects the number of neurons in parts of the brain. [1]Nutritional neuroscience is the scientific discipline that studies the effects various components of the diet such as minerals, vitamins, protein, carbohydrates, fats, dietary supplements, synthetic hormones, and food additives have on neurochemistry, neurobiology, behavior, and cognition.
Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. [1] Poor nutrition is a chronic problem often linked to poverty, food security, or a poor understanding of nutritional requirements. [2]
Energy intake is measured by the amount of calories consumed from food and fluids. [1] Energy intake is modulated by hunger, which is primarily regulated by the hypothalamus, [1] and choice, which is determined by the sets of brain structures that are responsible for stimulus control (i.e., operant conditioning and classical conditioning) and cognitive control of eating behavior.
Nutritional genomics, also known as nutrigenomics, is a science studying the relationship between human genome, human nutrition and health. People in the field work toward developing an understanding of how the whole body responds to a food via systems biology, as well as single gene/single food compound relationships.

The brain has to decide very quickly whether the food should be eaten or not. It was the findings in 1991, describing the first olfactory receptors that helped to prompt the research into taste. The olfactory receptors are located on cell surfaces in the nose which bind to chemicals enabling the detection of smells.
The brain constantly changes and rewires itself throughout adulthood, a process known as neuroplasticity. Evidence suggests that the brain changes in response to diet, exercise, social environment, stress, and toxin intake. These same external factors also influence genetic expression throughout adult life - a phenomenon known as genetic ...
