Introduction to Nutrition & Food Labels

Which statement best distinguishes nutrients from food in human biology?

• Nutrients are chemical substances; food contains many nutrients

• Nutrients are meals we eat; food is single molecules

• Nutrients are flavors in dishes; food is taste only

• Nutrients are cooking tools; food is edible utensils

Nutrition science is primarily concerned with which focus?

• How diet affects health and disease patterns

• How agriculture increases crop market prices

• How restaurants design profitable menus

• How flavors change during cooking processes

Which list correctly names the six essential nutrient classes?

• Proteins, lipids, nucleic acids, fiber, phytochemicals, water

• Carbohydrates, proteins, fats, vitamins, minerals, water

• Carbohydrates, amino acids, lipids, fiber, electrolytes, alcohol

• Sugars, starches, oils, enzymes, hormones, oxygen

Which grouping correctly identifies macronutrients versus micronutrients?

• Macronutrients: carbs, fats, proteins; Micronutrients: vitamins, minerals

• Macronutrients: fiber, water; Micronutrients: fats, amino acids

• Macronutrients: vitamins, minerals; Micronutrients: carbs, proteins

• Macronutrients: enzymes, hormones; Micronutrients: electrolytes

Which item is typically required on a packaged food label in the United States?

• Microscopic images of ingredients and allergens

• Soil type from farm and irrigation schedule

• Restaurant inspection grade and chef credentials

• Nutrition Facts panel with serving size and calories

A nutrient content claim such as “low sodium” differs from a health claim in which key way?

• Content claims require no rules; health claims have no oversight

• Content claims cite exercise plans; health claims list vitamin doses

• Content claims discuss flavors; health claims explain cooking methods

• Content claims describe nutrient levels; health claims link diet to disease risk

Which U.S. agencies primarily govern food labels and dietary guidelines?

• USDA and USPS for labeling; HHS and DHS for guidelines

• CDC and NIH for labeling; FEMA and SSA for guidelines

• EPA and NASA for labeling; DOE and DOC for guidelines

Which example illustrates a questionable ingredient sometimes found in packaged foods?

• Cold-pressed olive oil with polyphenols

• Partially hydrogenated oils contributing trans fats

• Fresh spinach rich in folate

• Rolled oats providing soluble fiber

When interpreting a Nutrition Facts panel, which strategy helps evaluate sugar content?

• Estimate sweetness based on brand popularity

• Compare added sugars grams to percent Daily Value

• Ignore grams and focus on package color design

• Multiply serving size by cooking temperature
