    Dehydration is the depletion in total body water content due to pathologic water losses, diminished water intake or a combination of both.

  • Development Coordination Disorder

    Professional Description:

    Development Coordination Disorder is associated commonly with difficulties in learning, behavior, and psychosocial adjustment, in addition to core deficits in motor function.

  • Diabetic ketoacidosis

    Professional Description:

    Diabetic ketoacidosis is a very serious condition which results in alterations in pH and electrolyte balance leading to acidosis and dehydration caused by a lack or relative deficiency of insulin.

  • Dietary Reference Intakes

    Professional Description:

    An "umbrella" term for four nutrient-based reference values that are used to assess and plan the diets of healthy people. The reference values include: the Estimated Average Requirement (EAR), the Recommended Dietary Allowance (RDA), the Adequate Intake (AI) and the Tolerable Upper Intake Level (UL). Relevant to U.S.A. and Canada only.

  • Dietary Reference Standards

    Dietary Reference Standards are nutrient intake values established as goals for individuals or groups for good nutrition and health.

  • Dietary status

  • Distribution of observed intakes

    Professional Description:

    The distribution of observed intakes represents the variability of observed intakes in the population of interest.

  • Distribution of Requirements

    Professional Description:

    The distribution of requirements reflects the individual-to-individual (between person) variability in requirements. Variability exists because not all individuals in a group have the same requirements for a nutrient, even if they are similar in characteristics such as age and sex.

  • Distribution of usual intakes

    Professional Description:

    The distribution of usual intakes is the long-run average nutrient intakes of individuals in the population. The distribution should reflect only the individual-to-individual (between-person) variability in intakes. Statistical procedures may be used to adjust the distribution of observed intakes by partially removing the day-to-day variability in individual intakes, so the adjusted distribution more closely resembles a usual intake distribution. Sometimes referred to as the "usual intake distribution".

  • Dose-response assessment

    Professional Description:

    Dose-response assessment is the second step in a risk assessment in which the relationship between nutrient intake and adverse effect (in terms of incidence and/or severity of the effect) is determined.

  • Doubly-labelled water

    Professional Description:

    Doublly-labelled water is a form of indirect calorimetry where the average metabolic rate is measured over a period of time. This process is done by administering a dose of doubly-labelled water (water in which both the hydrogen and the oxygen have been partly or completely replaced with an uncommon isotope), then tracking the loss of deuterium and O-18 in the subject, over time, through the use of regular sampling of heavy isotope concentrations in the body water (by sampling saliva, urine, or blood).
