  • EAR cut-point method

    Professional Description:

    EAR cut-point method is used to determine the prevalence of inadequacy for a group or more specifically the proportion of a group with intakes below the EAR.

  • Effect size

    Professional Description:

    The effect size is the difference in outcomes between the intervention and control groups divided by the standard deviation.

  • Encopresis

    Professional Description:

    Encopresis or fecal incontinence occurs when stool (formed, semiformed, or liquid) seeps around the fecal mass and leaks out.

  • Endurance capacity

    Professional Description:

    Endurance capacity is the time to fatigue (or time to exhaustion) at a fixed exercise intensity or pace.

  • Enteric coated

    Professional Description:

    Enteric coated is being or possessing a coating designed to pass through the stomach unaltered and to disintegrate in the intestines.

  • Enterobacter sakazakii

    Professional Description:

    Referred to now as Cronobacter spp.

  • Enterohepatic circulation

    Professional Description:

    Enterohepatic circulation is circulation between the liver and gastrointestinal tract.

  • Enteropathy

    Professional Description:

    Enteropathy is a disease of the intestinal tract.

  • Enzyme-linked immunosorbent assay

    Professional Description:

    Enzyme-linked immunosorbent assay (ELISA)is a rapid immunochemical test that involves an enzyme and an antibody or antigen. ELISA tests are utilized to detect substances that have antigenic properties, primarily proteins.

  • Epididymis

    Professional Description:

    Epididymis is an elongated structure connected to the posterior surface of the testis that stores and matures spermatozoa and transports spermatozoa from the testis to ductus deferens (vas deferens).

  • Episode of care

    Professional Description:

    Episode of care is “a health problem from its first encounter with a health care provider through completion of the last encounter related to that problem”.

  • Epitope

    Professional Description:

    An epitope is a single antigenic site on a protein against which an antibody reacts. An eitope is composed of several amino acids in a sequence and configuration that elicits an immunological response and the production of antibodies designed to couple with that specific structure.

  • Erythropoiesis

    Professional Description:

    Erythropoiesis, also called erythroctopoiesis, is the production of red blood cells.

  • Estimated Average Requirement

    Professional Description:

    Estimated Average Requirement (EAR) is the nutrient intake value that is estimated to meet the requirement defined by a specified indicator of adequacy in 50% of the individuals in a life stage and gender group.

  • Estimated Energy Requirement

    Professional Description:

    Estimated Energy Requirement (EER) is the average dietary energy intake that is predicted to maintain energy balance in a healthy adult of a defined age, gender, weight, height, and a level of physical activity that is consistent with good health.

  • Euvolemia

    Professional Description:

    Euvolemia is the presence of the proper amount of blood or fluid in the body.

  • Excitotoxicity

    Professional Description:

    A process where neurons are damaged or destroyed through excess stimulation and receptor activation because of imbalances in neurotransmitters and ions. Neuronal cell membranes are damaged because of the primary injury, leading to a loss of K+ and an influx of Na+ and Ca+ ions. Neurons use electrical signaling to communicate, and this ion imbalance causes depolarization of the cell, which leads to random propagation of nerve impulses. Uncontrolled firing of neurons results in the undesired release of neurotransmitters and glutamate, which damage receptors on surrounding neurons, increasing the rate of cell death by up-regulating cell apoptosis pathways.

  • Excitotoxins

    Professional Description:

    Excitotoxins are molecules that act as excitatory neurotransmitters, and can lead to neurotocity when taken in excess.

  • Exclusive breastfeeding

    Professional Description:

    Exclusive breatsfeeding is when no food or liquid other than breastmilk, not even water, is given to the infant from birth by the mother, health care provider, or family member/supporter.

  • Exogenous iron source

    Professional Description:

    An exogenous iron source is iron from dietary or supplementary sources.

  • Extensively hydrolyzed infant formula

    Professional Description:

    An extensively hydrolyzed infant formula is a formula in which the constituents, especially the proteins, have been hydrolyzed (“digested”) by enzymatic activity to yield single amino acids and small peptides to achieve a product that has few proteins capable of initiating an immunological response.
