Kuwait MOH Dietitian key terms

Energy used by the body at complete rest to maintain vital functions such as breathing, circulation, and cell production, measured under standard conditions after an overnight fast and rest.

Energy expended at rest over 24 hours, slightly higher than BMR because it includes minimal activity and is usually measured by indirect calorimetry or predicted by equations such as Mifflin-St Jeor.

Energy cost of digesting, absorbing, and metabolizing nutrients, typically about 10 percent of total energy intake and varying by macronutrient, being highest for protein and lowest for fat.

Sum of basal metabolic rate, thermic effect of food, and activity thermogenesis, representing the total daily energy a person uses and the basis for estimating energy requirements.

Ratio of total energy expenditure to basal metabolic rate, used to express habitual activity and to multiply BMR when estimating daily energy needs for sedentary to very active individuals.

Technique that estimates energy expenditure by measuring oxygen consumption and carbon dioxide production, often with a metabolic cart, and yields a respiratory quotient indicating substrate oxidation mix.

Ratio of carbon dioxide produced to oxygen consumed during metabolism, near 0.7 for fat oxidation, 0.8 for protein, and 1.0 for carbohydrate, useful for assessing overfeeding or underfeeding.

Ranking of carbohydrate-containing foods by how much they raise blood glucose over two hours compared with a reference food, useful for counseling in diabetes and insulin resistance.

Product of a food's glycemic index and its available carbohydrate content per serving, giving a more practical estimate of blood glucose impact than glycemic index alone.

Non-digestible carbohydrates and lignin from plants, including soluble and insoluble types, which affect bowel function, glycemic response, and lipid levels and are recommended in adequate daily amounts.

Nine amino acids the body cannot synthesize in adequate amounts and must obtain from food, including histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Method for evaluating dietary protein quality by comparing a food's amino acid profile with human requirements and correcting for digestibility, scoring from zero to one.

Difference between nitrogen intake from protein and nitrogen lost in urine, feces, and sweat, used to assess whether protein intake meets needs, with positive balance indicating anabolism.

Proportion of a nutrient consumed that is absorbed and available for physiological use, influenced by food form, absorption enhancers and inhibitors, and individual nutritional status.

Iron bound within hemoglobin and myoglobin in animal foods, absorbed more efficiently than plant iron and less affected by dietary inhibitors, making it a key source in iron-deficiency prevention.

Iron found in plant foods and fortified products, whose absorption is enhanced by vitamin C and inhibited by phytates, tannins, and calcium, requiring careful meal planning.

Iron-storage protein measured in serum as the most sensitive indicator of iron stores, low values indicating depletion before hemoglobin falls and high values reflecting inflammation or overload.

Iron-containing protein in red blood cells that carries oxygen, measured to diagnose anemia, with low concentrations suggesting iron deficiency when other causes are excluded.

Health consequences of inadequate iodine intake, including goiter, hypothyroidism, and impaired cognitive development, prevented mainly through iodized salt and monitored by urinary iodine.

Insufficient vitamin D status, assessed by serum 25-hydroxyvitamin D, causing impaired calcium absorption, bone loss, and rickets or osteomalacia, common in hot climates with limited sun exposure.

Intake level sufficient to meet the needs of nearly all healthy people in a population group, used for planning diets and assessing adequacy, often set two standard deviations above average requirement.

Highest average daily nutrient intake likely to pose no risk of adverse health effects for almost all individuals, used to guard against excessive supplementation and fortification.

Family of nutrient reference values including estimated average requirement, recommended dietary allowance, adequate intake, and upper level, used for planning and assessing diets of healthy people.

Weight in kilograms divided by height in meters squared, used to classify underweight, normal weight, overweight, and obesity, with population-specific cutoffs for some Asian groups.

Measure of abdominal adiposity taken at a defined landmark, used with BMI to assess cardiometabolic risk, with elevated values indicating central obesity and increased disease risk.

Measurement of body size and proportions such as weight, height, circumferences, and skinfold thickness, used to assess growth, nutritional status, and risk in individuals and populations.

Serial measurement of weight, height, and head circumference plotted on growth charts to detect faltering growth, obesity, or malnutrition early in infants and children.

Clinical tool combining history of weight change, dietary intake, gastrointestinal symptoms, functional capacity, and physical examination to classify patients as well nourished or mildly, moderately, or severely malnourished.

Screening tool that scores nutritional status and disease severity to identify hospitalized patients who need formal nutrition assessment and intervention, widely used on admission.

Systematic evaluation of anthropometric, biochemical, clinical, and dietary data, often summarized as the ABCD approach, to diagnose nutritional problems and plan appropriate therapy.

Spectrum of deficiency states from inadequate protein and energy intake, including marasmus and kwashiorkor, marked by wasting, edema, impaired immunity, and growth failure.

Individualized nutrition assessment and counseling provided by a dietitian to treat a disease or condition, with measurable goals and follow-up as part of clinical care.

Structured framework for dietetics practice with four steps: nutrition assessment, nutrition diagnosis, nutrition intervention, and nutrition monitoring and evaluation, documented in standardized language.

Delivery of liquid formula nutrients into the gastrointestinal tract by tube or orally, used when oral intake is inadequate but the gut functions, with aspiration and tolerance as key concerns.

Provision of nutrients directly into the bloodstream through a central or peripheral vein when the gastrointestinal tract cannot be used or fails to absorb adequately.

Potentially fatal shift of electrolytes, especially phosphate, potassium, and magnesium, after reintroducing nutrition to a malnourished patient, requiring gradual feeding and close biochemical monitoring.

Systematic food safety system that identifies biological, chemical, and physical hazards, establishes control points and limits, and monitors them to prevent unsafe food reaching consumers.

Step in a food production process where a control measure can be applied to prevent, eliminate, or reduce a food safety hazard to an acceptable level, such as cooking temperature or chilling.

Practices and conditions that prevent foodborne illness, including safe sourcing, temperature control, hygiene, separation of raw and cooked foods, and proper holding and reheating.

Feeding an infant only breast milk, without water, formula, or other foods, for the first six months, as recommended by WHO and adopted in Kuwait, with complementary foods added thereafter.

Introduction of safe, adequate solid and liquid foods alongside breast milk from six months while breastfeeding continues, supporting growth and developmental readiness for chewing and self-feeding.

Skeletal disorder of reduced bone mass and deteriorated bone structure causing fragility fractures, prevented and managed with adequate calcium and vitamin D, protein, and weight-bearing activity.

Shift in population diets toward energy-dense processed foods and reduced physical activity, driving rising obesity and noncommunicable diseases in countries such as Kuwait.

Planned activities that enable people to increase control over and improve their health, including nutrition education, policy, and community programs targeting diet-related risk factors.

Population-specific advice translating nutrient recommendations into practical food choices, often illustrated as a plate or pyramid and adapted to local food culture and availability.

Clinical decision-making that integrates the best available research evidence, professional expertise, and patient values and preferences to improve outcomes.

Structured synthesis of all relevant studies addressing a focused question, using explicit search and appraisal methods and often meta-analysis to produce pooled estimates.

Voluntary agreement to a nutrition intervention or research participation after receiving understandable information about purpose, risks, benefits, and alternatives, respecting autonomy and confidentiality.

Principles guiding dietetics practice, including beneficence, nonmaleficence, autonomy, justice, confidentiality, competence, and avoidance of conflicts of interest in patient care and research.

Range of roles, activities, and responsibilities a dietitian is trained and legally permitted to perform, defining boundaries for clinical care, counseling, and delegation within a jurisdiction.
