Replacing nutrients such as B vitamins and iron that were lost during processing of a grain, restoring them to levels close to those in the whole grain.

- Added sugars
- Related: Empty calories, Dietary Guidelines for Americans
Sugars and syrups added to foods and beverages during processing or preparation, as distinct from sugars naturally present in fruit, milk, and other whole foods.
- Portion size
- Related: Serving size, Glycemic index
The amount of a specific food a person chooses to eat at one time, which may differ from a standard serving and strongly influences total calorie intake.
- Serving size
- Related: Portion size, Nutrition Facts label
A standardized amount of food used on nutrition labels and in dietary guidance to make nutrient comparisons consistent across products.
- Nutrition Facts label
- Related: Serving size, Added sugars
The standardized panel on packaged foods that lists serving size, calories, and amounts of key nutrients per serving to help consumers compare products.
- Food insecurity
- Related: Food desert, Food bank
Limited or uncertain access to enough safe, nutritious food for an active, healthy life because of money or other resources.
- Food desert
- Related: Food insecurity, Food bank
A geographic area where residents have limited access to affordable, nutritious food, often because supermarkets are distant and few transportation options exist.

- Food waste
- Related: Food recovery, First in, first out
Edible food that is discarded or lost at any point from production through consumption, representing wasted resources and avoidable environmental and economic costs.
- Hazard Analysis and Critical Control Point (HACCP)
- Related: Temperature danger zone, Cross-contamination
A systematic food safety system that identifies biological, chemical, and physical hazards and sets controls at critical points in food production to prevent contamination.
- Temperature danger zone
- Related: HACCP, Two-hour rule
The range of roughly 40 to 140 degrees Fahrenheit in which bacteria multiply most rapidly, so perishable foods should be kept outside this range.
- Two-hour rule
- Related: Temperature danger zone, HACCP
The food safety guideline that perishable foods left at room temperature should be discarded after two hours, or after one hour when the air is very hot.
- Cross-contamination
