Chapter 2 Food and Nutrition

Diet-planning principles

Adequacy
Balance
kCalorie (energy) control
Nutrient density
Moderation
Variety

Adequacy (dietary)

providing all the essential nutrients, fiber, and energy in amounts sufficient to maintain health

Balance (dietary)

providing foods in proportion to one another and in proportion to the body's needs

kCalorie (energy) control

management of food energy intake

Nutrient density

a measure of the nutrients of a food provides relative to the energy it provides. The more nutrients and the fewer kcalories, the higher the nutrient density

Empty-kcalorie foods

a popular term used to denote foods that contribute energy but lack protein, vitamins, and minerals

Nutrient profiling

ranking foods based on their nutrient composition

Moderation (dietary)

providing enough but not too much of a substance

variety (dietary)

eating a wide selection of foods within and among the major food groups

A healthy diet

Emphasizes a variety of fruits, vegetables, whole grains, and fat-free and low-fat milk products
Includes lean meats, poultry, fish, legumes, eggs, and nuts
Is low in saturated and trans fats, cholesterol, salt (sodium), and added sugars
Stays within your daily energy needs for your recommended body weight

Five food groups

Fruits
Vegetables
Grains
Meat and legumes
Milk

Food group plans

diet-planning tools that sort foods into groups based on nutrient content and then specify that people should eat certain amounts of foods from each group

Legumes

plants of the bean and pea family, with seeds that are rich in protein compared with other plant-derived foods

Discretionary kcalorie allowance

the kcalories remaining in a person's energy allowance after consuming enough nutrient-dense foods to meet all nutrient needs for a day

Healthy eating index

a measure that assesses how well a diet meets the recommendations of the dietary guidelines for Americans and MyPyramid

Exchange lists

diet-planning tools that organize foods by their proportions of carbohydrate, fat, and protein. Foods on any single list can be used interchangeably

Processed foods

foods that have been treated to change their physical, chemical, microbiological, or sensory properties

Fortified

the addition to a food of nutrients that were either not originally present or present in insignificant amounts. Fortification can be used to correct or prevent a widespread nutrient deficiency or to balance the total nutrient of profile of a food

Refined

The process by which the coarse parts of a food are removed. When wheat is refined into flour, the bran germ, and husk are removed, leaving only the endosperm

Enriched

the addition to a food of nutrients that were lost during processing so that the food will meet a specified standard

Whole grain

a grain that maintains the same relative proportions of starchy endosperm, germ, and bran as the original (all but the husk); not refined

Grain enrichment nutrients

Iron
Thiamin
Riboflavin
Niacin
Folate

Textured vegetable protein

processed soybean protein used in vegetarian products such as soy burgers

Functional foods

contain physiologically active compounds that providde health benefits beyond basic nutrition

Imitation foods

foods that substitute for and resemble another food, but are nutritionally inferior to it with respect to vitamin, mineral, or protein content. If the substitute is not inferior to the food it resembles and if its name provides an accurate description of the product, it need not be labeled "imitation

Food substitutes

foods that are designed to replace other foods

Daily Values (DV)

Reference values developed by the FDA specifically for use on food labels

Percent Daily Value (%DV)

The percentage of a Daily Value recommendation found in a specified serving of food for key nutrients based on a 2000-kcalorie diet

Nutrient claims

statements that characterize the quantity of a nutrient in a food

Health claims

statements that characterize the relationship between a nutrient or other substance in a food and a disease or health-related condition

Free

Nutritionally trivial and unlikely to have a physiological consequence; synonyms include: without, no and zero. A food that does not contain a nutrient naturally may make such a claim, but only as it applies to all similar foods

Good source of

the product provides between 10 and 19 percent of the Daily Value for a given nutrient per serving

Healthy

a food that is low in fat, saturated fat, cholesterol, and sodium and that contains at least 10 percent of the Daily Values for vitamin A, vitamin C, iron, calcium, protein , or fiber

High

20 percent or more of the Daily Value for a given nutrient per serving; synonyms include rich in, or excellent source

Less

at least 25 percent less of a given nutrient or kcalories than the comparison food; synonyms include fewer and reduced

Light or lite

one-third fewer kcalories than the comparison food; 50 percent or less of the fat or sodium than the comparison food; any use of the term other than as defined must specify what it is referring to

Low

an amount that would allow frequent consumption of a food without exceeding the Daily Value for the nutrient. A food that is naturally low in a nutrient may make such a claim, but only as it applies to all similar foods; synonyms include little, few, and low source of

More

at least 10 percent more of the Daily Value for a given nutrient than the comparison food; synonyms include added and extra

Organic

on food labels, that at least 95 percent of the product's ingredients have been grown and processed according to USDA regulations defining the use of fertilizers, herbicides, insecticides, fungicides, preservatives, and other chemical ingredients

kCalorie-free

fewer than 5 kcalories per serving

Low kcalorie

40 kcalories or less per serving

Reduced kcalorie

at least 25 percent fewer kcalories per serving than the comparison food

Percent fat-free

may be used only if the product meets the definition of low fat or fat-free and must reflect the amount of fat in 100 grams

Fat-free

less than 0.5 gram of fat per serving; synonyms include zero-fat, no-fat, and nonfat

Low fat

3 grams or less fat per serving

Less fat

25 percent or less fat than the comparison food

Saturated fat-free

less than 0.5 gram of saturated fat and trans fat combined than the comparison food

Trans fat-free

less than 0.5 gram of trans fat and less than 0.5 saturated fat per serving

Cholesterol-free

less than 2 milligrams cholesterol per serving and 2 grams or less saturated fat and trans fat combined per serving

Low cholesterol

20 milligrams or less cholesterol per serving and 2 grams or less saturated fat and trans fat combined er serving

Less cholesterol

25 percent or less cholesterol than the comparison food (reflecting a reduction of at least 20 miligrams per serving), and 2 grams or less saturated fat and trans fat combined per serving

Extra lean

less than 5 grams of fat, 2 grams of saturated fat and trans fat combined, and 95 milligrams of cholesterol per serving and per 100 grams of meat, poultry, and seafood

Lean

less than 10 grams of fat, 4.5 grams of saturated fat and trans fat combined, and 95 milligrams of cholesterol per serving and per 100 grams of meat, poultry, and seafood. For mixed dishes such as burritos and sandwiches, less than 8 grams of fat, 3.5 grams of saturated fat, and 80 milligrams of cholesterol per reference amount customarily consumed

High fiber

5 grams or more fiber per serving. A high-fiber claim made on a food that contains more than 3 grams fat per serving and per 100 grams of food must also declare total fat

Sugar free
