The science of nutrition: linking food, function, and health. Chapter 1: nutrition deficiencies, primary deficiency occurs when a person does not consume enough of a nutrient, a direct consequence of inadequate intake, secondary deficiency occurs when: A person cannot absorb enough of a nutrient in his or her body. Too much of a nutrient is excreted from the body. A nutrient is not utilized efficiently by the body. Deficiency symptoms: subclinical deficiency occurs in the early stages; few or no symptoms are observed, covert symptoms are hidden and require laboratory tests or other invasive procedures to detect, symptoms of nutrition deficiency that become obvious are overt. Examine patterns of health and disease in defined populations. Indicate relationships between factors, not cause and effect: observational studies: Involve assessing nutritional habits, disease trends, or other health phenomena of large populations. Determine the factors that may influence these phenomena: case control studies are more complex observational studies with additional design features.
