An ADI is "the amount of a food additive, corrected for body weight, that can be ingested daily over a lifetime without appreciable health risk". The ADI is determined by bodies such as HPFB, JECFA, or FDA and is generally 1% of the highest dose at which studies have demonstrated no harmful effects.

A range of intakes for a particular energy source that is associated with a reduced risk of chronic disease while providing adequate intakes of essential nutrients. The AMDR of a macronutrient is expressed as a % of total energy intake because its requirement is not independent of other energy fuel sources or of the total energy requirement of the individual.

ACT is a third-wave cognitive behavioural therapy (3wCBT). 3wCBT advocates acceptance of physical discomfort or other adverse or negative internal experiences, verses avoidance. When applied to weight loss, 3wCBTs may increase an individual’s awareness and psychological flexibility in order to improve their ability to recognize and act on cues that may lead overeating. Specifically, the ACT approach seeks to promote healthy behaviour habits through acceptance and mindfulness in moments of behavioural decision-making.

Alcohol dependence is an older classification used in the DSM-IV, which corresponds to moderate or severe alcohol use disorder in the DSM-V. While the DSM-IV classified problematic alcohol use into two categories, alcohol abuse (one or more symptoms) and alcohol dependence (three or more symptoms), the DSM-V describes alcohol use disorders as a spectrum from mild (two to three symptoms) to severe (six or more symptoms). Individuals with alcohol dependence typically have increased tolerance (i.e. need to consume more alcohol to feel the same effects) and withdrawal symptoms when alcohol use is stopped (e.g. nausea, sweating, difficulty sleeping, shakiness, hallucinations, racing heart, seizures).

Allele is one of the variant forms of a gene at a particular location on a chromosome. Different alleles produce variation in inherited characteristics such as hair color or blood type. In an individual, one form of the allele (the dominant one) may be expressed more than another form (the recessive one).

An allergen is a special type of antigen that causes an IgE antibody response.

An allergen-specific IgE is an IgE antibody formed in response to a specifc allergen. These are the antibodies that are detected in allergy tests such as RAST and skin tests.

Allergic asthma refers is asthma caused by immunological mechanisms.

Allergic disease is caused by exposure to specific antigens (allergens) in people who are sensitized to the antigens.

Allergic eosinophilic gastroenteritis is a food-related gastrointestinal hypersensitivity disease involving IgE and/or non-IgE mechanisms. It can occur at any age, including in young infants. Weight loss or failure to thrive is typical for this disorder.

Allergic rhinitis is an inflammation of the nasal mucous membrane induced by IgE antibody to specific allergens.

Allergic sensitization is the presence of IgE antibodies against environmental and/or food antigens.

An allergy is an inappropriate or exaggerated reaction of the immune system to substances that, in the majority of people, cause no symptoms. Symptoms of allergic disease may be caused by exposure of the skin to a chemical, of the respiratory system to particles of dust or pollen (or other substances), or of the stomach and intestines to a particular food. In its broadest sense, it is applied to all types of immunologically-mediated hypersensitivity reactions. Previously, the term was restricted to IgE-mediated hypersensitivity.

All-rac (racemic)-alpha-tocopherol is synthetic vitamin E.

Alopecia is a complete or partial loss or absence of hair.

Alopecia areata is a condition of undetermined etiology characterized by non-scarring and circumscribed areas of baldness on the scalp, eyebrows and beard area which are usually asymmetric.

Alopecia totalis is a complete loss of scalp hair.

Alopecia universalis is the total loss of all body hair.

A serine protease inhibitor present in blood that protects tissue from inflammatory cells enzymes, especially elastase.

Alpha-tocopherol is the biologically active form of vitamin E. It has three asymmetric carbon atoms in the side chain, at positions 2, 8 and 12, each of which can be designated as "R" or "S". This formation leads to eight possible stereoisomers: RRR, RSR, RRS, RSS, SRR, SSR, SRS, and SSS. The naturally-occurring form of alpha-tocopherol is RRR-alpha-tocopherol. For the purposes of establishing requirements and recommended intakes, vitamin E is defined as the two R-stereoisomers of alpha-tocopherol (i.e. RRR, RSR, RRS and RSS).

Alpha-tocopherol equivalents (TE) are used in most nutrient databases to show the vitamin E content of foods. This unit incorrectly attributes vitamin E activity to tocopherols and tocotrienols other than alpha-tocopherol. The new RDA is for alpha-tocopherol only.

Anaphylactoid is a reaction with symptoms often indistinguishable from anaphylaxis in people in whom no evidence of IgE-mediated allergy can be demonstrated.

Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death. Signs and symptoms can occur within minutes of exposure to an allergen. In rarer cases, the time frame can vary up to several hours after exposure. The ways that these symptoms occur may vary from person to person and even from episode to episode in the same person. An anaphylactic reaction can involve any of the following symptoms: (skin) hives, swelling, itching, warmth, redness, rash, (respiratory)coughing, wheezing, shortness of breath, chest pain/tightness, throat tightness, hoarse voice, nasal congestion or hay fever-like symptoms (runny, itchy nose and watery eyes, sneezing), trouble swallowing, (gastrointestinal) nausea, pain/cramps, vomiting, diarrhea, (cardiovascular) pale/blue colour, weak pulse, passing out, dizzy/lightheaded, shock, (other) anxiety, feeling of “impending doom”, headache, uterine cramps in females. These symptoms may appear alone or in any combination regardless of the triggering allergen.

Anthropometrics is the measurement of the physical dimensions and gross composition of the human body (e.g. waist circumference, skinfold measurements, height).

An antibody is a protein, also called an immunoglobulin (Ig), that is manufactured by lymphocytes to neutralize an antigen. Humans make five types of antibodies - IgA, IgD, IgE, IgG,and IgM.

An antigen is a substance that can trigger an immune response, resulting in production of an antibody as part of the body's defense against infection and disease. Many antigens are foreign proteins (those not found naturally in the body). Bacteria, viruses and other microorganisms commonly contain many antigens, as do pollens, dust mites, molds, foods, and other substances.

An antigen presenting cell is a white blood cell that engulfs and degrades foreign proteins and displays the individual molecules on surface receptors for recognition by T helper cells.

Antigen processing is the display of antigens on the surface of a macrophage that has engulfed and partially degraded them, a preconditioning for recognition and a protective response by T cells.

Antigenicity is the ability of an antigen to trigger an immune response.

Atopic disease is a genetic predisposition toward the development of immediate (Type I) hypersensitivity reactions against common environmental allergens (atopic allergy). The most common clinical manifestations are allergic rhinitis, bronchial asthma, atopic dermatitis, and food allergy occurring less frequently.

Atopy is a personal or familial tendency to produce IgE antibodies in response allergens, and to develop typical symptoms such as asthma, rhinoconjunctivitis or eczema/dermatitis.

Continuous subcutaneous insulin infusion is a method of insulin delivery. Insulin is delivered by a microcomputer (pump) in very small amounts from a syringe reservoir through a thin tube (infusion set) that is connected to a needle or cannula which is inserted into the subcutaneous tissue. The pump is programmed to deliver a continuous infusion of basal insulin according to physiological needs and then programmed to deliver boluses of fast or rapid-acting insulin as needed to cover carbohydrate intake or to correct hyperglycemia.

"A variable that can theoretically take any value and in practice can take a large number of values with small differences between them (e.g. height). Continuous variables are also sometimes called interval data."

The tendency to overeat in response to different stimuli.

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

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.

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".

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.

Glossitis is a condition where the tongue is swollen, has a smooth surface (normally it is covered by small bumps called papillae), and feels sore or tender. The colour of the tongue can be paler than usual or bright red. There are many possible causes of glossitis, including allergies, very dry mouth (as in Sjogren syndrome), infection or injuries to the tongue. Glossitis can affect the ability to chew, swallow and talk. It generally resolves once the underlying cause is addressed.

A type of immunoglobulin. Levels of IgE antibody are elevated in individuals with atopic conditions such as asthma, allergic rhinitis and atopic dermatitis. IgE antibodies are produced against specific allergens and determined by both genetic factors and exposure to allergens. Allergens will trigger an allergic response, in sensitized individuals, by attaching to IgE antibodies bound to mast cells. This results in mast cell release of inflammatory mediators, which trigger acute tissue inflammation.

Abbreviated IgE. A class of immunoglobulins that includes the antibodies elicited by an allergic substance (allergen). A person who has an allergy usually has elevated blood levels of IgE. IgE antibodies attack and engage the invading army of allergens

Immunoglobulins are proteins found in blood and in tissue fluids. Immunoglobulins make up gamma globulin; all antibodies are immunoglobulins. There are five classes (IgA, IgD, IgE, IgG, and IgM) of immunoglobulins which differ in the structure of their polypeptide heavy chains. Immunoglobulins are produced by cells of the immune system called B-lymphocytes. Their function is to bind to substances in the body that are recognized as foreign antigens (often proteins on the surface of bacteria and viruses). This binding is a crucial event in the destruction of the microorganisms that bear the antigens. Immunoglobulins also play a central role in allergies when they bind to antigens that are not necessarily a threat to health and provoke an inflammatory reaction.

"Indicators of adequacy" are criteria that can be used to determine a requirement for a nutrient. Examples include absence of clinical deficiency signs and symptoms; biochemical parameters reflecting the function or storage of the nutrient; circulating levels of a nutrient; etc. For each nutrient, different intakes are required to meet different indicators of adequacy. For example, more iron is needed to maintain iron stores (for which the indicator of adequacy would be a defined level of serum ferritin) than to prevent anemia (for which the indicator of adequacy would be a defined level of hemoglobin).

"A fundamental way to analyze a randomized controlled trial in which all subjects allocated to each arm of the trial are analyzed “as intended” upon randomization, whether or not they actually received the exposure allocated or completed treatment. Failure to follow this approach defeats the main purpose and advantage of random allocation and can cause serious confounding bias. This approach is virtually always required as part of the primary analysis of studies aiming to influence clinical or public-health decisions and policy formulation. It may be complemented by an explanatory analysis, in which subjects are analyzed according to the exposure they actually experienced (with adjustment for possible confounders, i.e., with an analytic approach similar to an observational cohort study), or in which some participants (e.g., subjects who complied poorly with the protocol) are excluded from analyses. An intention-to-treat analysis does not determine whether and how to impute missing data on the outcome measure. Because of its pragmatic nature, ITT can underestimate treatment efficacy or have a low explanatory capacity."

Lactose malabsorption is a physiological problem that presents as lactose intolerance. It is caused by the imbalance between the amount of ingested lactose and the capacity for lactase to hydrolyze the disaccharide due to a deficiency in levels of the lactase enzyme. It is measured by a breath hydrogen test after the ingestion of a lactose load.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the presence of hepatic steatosis in conjunction with at least one cardiometabolic risk factor (e.g. elevated waist circumference, blood glucose, blood pressure or dyslipidemia). The term MetALD is used to describe individuals with MASLD who consume greater amounts of alcohol (>140 g/week for women and >210 g/week for men). MASLD was previously referred to as nonalcoholic fatty liver or nonalcohol-related fatty liver disease (NAFLD) and metabolic dysfunction-associated fatty liver disease (MAFLD).

Metabolic syndrome is a collection of risk factors (at least three of the following: large waist circumference, high blood pressure, high fasting blood glucose, high serum triglycerides, low serum HDL cholesterol) that is associated with an increased risk of cardiovascular disease beyond what is expected from individual risk factors.

In order to study the relationships among variables, observational studies are performed. Unlike controlled experimental designs where only certain variables are allowed to vary (at prespecified levels), in observational studies the variables are observed and recorded. Often some of the variables are controlled as much as possible. Consider a long term study on a drug involving humans where a variable that needs to be controlled is diet. The diet guidelines are set but these will probably be broken from time to time (or maybe often) by some of the human subjects. Contrast this with a lab setting, where the diet of animals can be controlled.

In observational studies, cause and effect are hard (often impossible) to establish. But associations and predictabilities among variables can be investigated. Such associations and predictabilities may be further studied in a lab setting.

(POI) occurs after abdominal surgery and involves a transient cessation of bowel function. There may be a reduction in activity sufficient to prevent effective transit of intestinal contents. POI is caused by a complex interaction between inhibitory neural reflexes, neurotransmitters, inflammatory mediators, and endogenous and exogenous opioids and usually resolves within two to three days. It can cause patient discomfort, increase postoperative complications, negatively affects patient nutritional status, and increases length of stay.

Prebiotics are defined as non-digestible food ingredients (dietary fibre) that beneficially affect the host by selectively stimulating the growth and/or activity of one of more limited number of bacteria in the colon and thus improve host health. For a food ingredient to be considered a prebiotic, it must meet several criteria. These criteria include: it must neither be hydrolysed, nor absorbed in the upper part of the gastrointestinal tract; be selectively fermented by one or a limited number of potentially beneficial bacteria in the intestine; and it must be able to alter the colonic microflora towards a healthier composition.

helps determine a patient's needs within a given counselling context by assessing motivational characteristics, physical, manual and economic barriers and facilitators, and specific circumstantial rewards and penalties. The approach can avoid inappropriate techniques, for example trying to persuade an already-motivated patient that change is necessary. Skipping unnecessary steps frees time to focus on aspects of the knowledge, beliefs, attitudes and understanding that require modification.

"1. [In statistics:] A measure of the likelihood of random errors in the results of a study, meta-analysis or measurement. The greater the precision, the less random error. Confidence intervals around the estimate of effect from each study are one way of expressing precision, with a narrower confidence interval meaning more precision.
2. [In trial searching:] The proportion of relevant articles identified by a search strategy expressed as a percentage of all articles (relevant and irrelevant) identified by that strategy. Highly sensitive strategies tend to have low levels of precision. It is calculated as follows: Precision = Number of relevant articles/Number of articles identified."

Reliability refers to the extent to which a measure or tool obtains similar results over repeated trials/ uses (i.e. the trustworthiness). There are several types of reliability: Test-retest Reliability - whether the self-administered measure obtains similar results when repeated by the same individuals over time. Inter-rater Reliability - whether the measure obtains similar results when rated or scored by different people. Intra-rater Reliability - whether the measure obtains similar results when rated or scored by the same person over time.

Retinol, the dietary form of vitamin A, is a fat-soluble, antioxidant vitamin important in vision and bone growth. It belongs to the family of chemical compounds known as retinoids. Retinol is ingested in a precursor form; animal sources (milk and eggs) contain retinyl esters, whereas plants (carrots, spinach) contain carotenoids. Tissue cells convert these precursors to retinol, and then to either retinal or retinoic acid.

The Recommended Dietary Allowances (RDA) for vitamin A are listed as Retinol Activity Equivalents (RAE) to account for the different activities of retinol and provitamin A carotenoids. Sometimes RDAs are also listed in International Units (IU) because food and some supplement labels list vitamin A content in International Units (1 RAE in micrograms = 3.3 IU).

An organized framework for evaluating scientific information, which has as its objective a characterization of the nature and likelihood of harm resulting from excess human exposure to an environmental agent (in this case, a dietary nutrient). It includes the development of both qualitative and quantitative expressions of risk. The process of risk assessment can be divided into four major steps; hazard identification, dose-response assessment, exposure assessment, and risk characterization.

The process by which risk assessment results are integrated with other information to make decisions about the need for, method of, and extent of risk reduction. In addition to risk assessment results, risk management considers such issues as the public health significance of the risk, the technical feasibility of achieving various degrees of risk control, and the economic and social cost of this control.

A lay term for a skin eruption.

The skin test is a method of measuring the patient's level of IgE antibodies to specific allergens. Using diluted solutions of specific allergens, the physician either injects the patient with the solutions (intradermal test), or scratches (scratch test) or pricks the skin with a sharp lancet (prick test) through the allergen drop. A positive reaction appears as a small raised area surrounded by a flat red area on the skin (the wheal and flare reaction). A positive reaction to the skin test, especially with food allergens, does not always mean that the patient is will develop symptoms when the food is eaten.
