Nutrient density

A measure of how much protein, vitamins, minerals, and fiber a food provides relative to the calories it supplies. Foods high in these nutrients and low in added sugar and solid fat are described as nutrient dense.

Related: Empty-calorie food, Balanced diet
Empty-calorie food

A food that supplies energy mainly from added sugars or solid fats while contributing few vitamins, minerals, protein, or fiber. Regular intake can displace more nutritious choices and add excess calories.

Related: Nutrient density, Discretionary calories
Balanced diet

An eating pattern that supplies all essential nutrients in appropriate amounts by combining foods from the major food groups in suitable proportions, matched to a person's age, sex, activity level, and health status.

Related: Nutrient density, Dietary reference intakes
Dietary reference intakes

A set of nutrient reference values used for planning and assessing diets of healthy people, including recommended intakes, adequate intakes, and upper limits for daily consumption of each nutrient.

Related: Balanced diet, Food label
Food label

The printed panel on packaged food giving the ingredients list, serving size, calories, and amounts of key nutrients per serving. It lets consumers compare products and check for allergens or additives.

Related: Serving size, Dietary reference intakes
Serving size

The standardized quantity of a food used as the basis for the nutrition figures on a food label. Portions actually eaten may differ, so comparing intake requires measuring against this stated amount.

Related: Food label, Portion control
Foodborne illness

Sickness caused by eating food contaminated with harmful bacteria, viruses, parasites, or toxins. Symptoms often include nausea, vomiting, diarrhea, and abdominal cramps, and prevention depends on safe handling practices.

Related: Danger zone, Cross-contamination
Danger zone

The temperature range, roughly 4 to 60 degrees Celsius, in which bacteria multiply most rapidly in food. Perishable foods should not be held within this range for extended periods.

Related: Foodborne illness, Cross-contamination
Cross-contamination

The transfer of harmful microorganisms from one food, surface, or utensil to another. It commonly occurs when raw meat juices contact ready-to-eat foods or shared cutting boards during preparation.

Related: Foodborne illness, Danger zone
Mise en place

The practice of gathering, measuring, and arranging all ingredients and equipment before cooking begins. It improves efficiency, reduces errors, and helps keep the work area orderly and safe.

Related: Standard recipe, Work triangle
Standard recipe

A tested formula that lists exact ingredients, quantities, method, yield, and portion size in a consistent format. It allows the same dish to be reproduced with predictable quality and cost.

Related: Mise en place, Yield
Yield

The number of portions or total amount of product a recipe produces after preparation and cooking. Knowing yield allows cooks to scale recipes and calculate cost per serving accurately.

Related: Standard recipe, Portion control
Portion control

Deliberately measuring or estimating the amount of food served to one person. It supports balanced eating, reduces waste, and keeps food costs predictable in both homes and food service operations.

Related: Serving size, Yield
Maillard reaction

The browning that occurs when amino acids and sugars react under dry heat, producing brown color and savory flavors. It explains the crust on baked bread, seared meat, and toasted foods.

Related: Caramelization, Dry-heat cooking
Caramelization

The browning and flavor development that happens when sugars are heated without proteins present. It gives color and sweetness to cooked sugar syrups, grilled vegetables, and browned onions.

Related: Maillard reaction, Dry-heat cooking
Dry-heat cooking

A method that cooks food without added water or steam, using hot air, hot fat, or a hot surface. Examples include roasting, grilling, frying, and baking, which promote browning and concentrated flavor.

Related: Moist-heat cooking, Maillard reaction
Moist-heat cooking

A method that cooks food in or over water, steam, or another liquid. Boiling, steaming, poaching, and stewing tenderize food and preserve moisture but generally do not produce browning.

Related: Dry-heat cooking, Coagulation
Coagulation

The irreversible setting of protein molecules when heated, as when egg white turns opaque or meat fibers firm up. Overheating causes toughening, shrinkage, and loss of moisture in protein foods.

Related: Moist-heat cooking, Gelatinization
Gelatinization

The process in which starch granules absorb liquid and swell when heated, thickening the mixture. It is the basis of sauces, puddings, and cooked cereal products and is affected by sugar and acid.

Related: Coagulation, Standard recipe
Work triangle

The imaginary path linking the sink, refrigerator, and main cooking surface in a kitchen. A compact triangle with unobstructed routes reduces steps and improves efficiency and safety during food preparation.

Related: Mise en place, Kitchen safety
Kitchen safety

Practices that prevent burns, cuts, falls, and electrical or fire hazards during food preparation. They include safe knife handling, turning pot handles inward, and keeping flammables away from heat sources.

Related: Cross-contamination, Work triangle
Opportunity cost

The value of the next best alternative given up when a resource is used for one purpose instead of another. It helps families compare trade-offs when spending money, time, or energy.

Related: Budget, Resource management
Budget

A plan that estimates expected income and assigns spending for a set period. A written budget helps a household control expenditure, save toward goals, and adjust when actual costs differ from estimates.

Related: Opportunity cost, Fixed expense
Fixed expense

A recurring cost that stays roughly the same from period to period, such as rent or insurance premiums. It is distinguished from variable expenses that change with use or season.

Related: Variable expense, Budget
Variable expense

A cost that changes in amount from one period to the next depending on usage, prices, or needs. Food, utilities, and clothing are typical examples that require flexible planning.

Related: Fixed expense, Budget
Resource management

The process of identifying, allocating, and using available resources such as money, time, energy, and skills to meet goals. It involves planning, implementing, and evaluating decisions over time.

Related: Opportunity cost, Budget
Warp and weft

The two sets of yarns that form woven fabric. Lengthwise warp yarns are held under tension while crosswise weft yarns are interlaced over and under them to build the cloth structure.

Related: Selvage, Fabric grain
Selvage

The tightly finished lengthwise edge of woven fabric that does not fray. It marks the direction of the warp yarns and is usually removed or hidden in the seam allowance of a garment.

Related: Warp and weft, Fabric grain
Fabric grain

The direction of the yarns in a woven fabric. Lengthwise grain runs parallel to the selvage, crosswise grain runs perpendicular, and true bias lies at a 45-degree angle with the most stretch.

Related: Selvage, Bias
Bias

A diagonal direction across woven fabric at approximately 45 degrees to the lengthwise and crosswise yarns. Bias-cut strips stretch and drape well, making them useful for facings and curved edges.

Related: Fabric grain, Seam allowance
Seam allowance

The narrow band of fabric between the stitching line and the raw edge of a seam. Its width is specified in the pattern guide sheet and affects fit, strength, and finishing method.

Related: Pattern layout, Bias
