Quiz: Food and Nutrition¶
Test your understanding of personal nutrition planning, food label analysis, and food systems with these review questions.
1. According to the World Health Organization's definition used in this chapter, what is health?¶
- The absence of diagnosed disease or infirmity
- A state of complete physical, mental, and social well-being
- A fixed label assigned once by a doctor
- A measure based only on recent lab test results
Show Answer
The correct answer is B. The WHO defines health as a state of complete physical, mental, and social well-being, not merely the absence of disease. This matters because it means someone managing a chronic condition well can still be healthy, and someone with a normal lab result is not automatically healthy in every sense. It is a dynamic condition shaped by biology, behavior, environment, and systems.

2. What is a "food desert"?¶
- A region where fast food is completely banned by local law
- A neighborhood where every resident chooses not to cook at home
- An area, often lower-income or rural, with limited access to affordable, nutritious food
- Any location more than one mile from the nearest supermarket
Show Answer
The correct answer is C. A food desert is an area, often lower-income or rural, where residents have limited access to affordable, nutritious food, particularly fresh produce, because grocery stores are scarce relative to convenience stores and fast food outlets. Food-desert residence is linked to higher rates of diet-related chronic disease, independent of individual willpower.

3. On a Nutrition Facts label, what does the % Daily Value (%DV) column tell you?¶
- What fraction of a 2,000-calorie reference diet's recommended intake one serving provides
- The exact number of servings left in the package
- Whether the product contains any added sugar at all
- How the ingredient list is ordered by weight
Show Answer
The correct answer is A. The %DV shows what fraction of a 2,000-calorie reference diet's recommended intake for a nutrient one serving provides. As a rule of thumb, 5% DV or less is considered low and 20% DV or more is considered high, which helps quickly judge whether a food is a poor or rich source of a given nutrient like sodium or fiber.

4. Two cereals have the exact same total sugar per serving, but Cereal A lists sugar as the second ingredient while Cereal B lists it fifth. What does this tell you about "added sugars" on their labels?¶
- Both cereals must have identical added sugar amounts since total sugar matches
- Ingredient order has no relationship to added sugar content
- Cereal B definitely contains more naturally occurring sugar than Cereal A
- Cereal A likely relies more heavily on added sugar, since ingredients are listed by descending weight
Show Answer
The correct answer is D. Ingredients are listed by descending weight, so a cereal listing sugar second is telling you sugar is the second-most abundant ingredient by mass. Since total sugar is identical but Cereal A's ingredient list places sugar higher, this suggests Cereal A relies more on added sugar rather than naturally occurring sugar to reach that total, since added sugars are distinct from naturally occurring sugars like those in fruit or milk.

5. A 150-calorie fruit smoothie provides protein, fiber, and vitamins, while a 150-calorie candy provides almost none of those. What concept explains why these are evaluated differently despite equal calories?¶
- Serving size standardization
- Nutrient density
- Added sugar labeling requirements
- The Estimated Energy Requirement formula
Show Answer
The correct answer is B. Nutrient density is the amount of beneficial nutrients, such as fiber, protein, vitamins, and minerals, a food delivers per calorie. Two foods can have identical calorie counts but very different nutrient density, which is why comparing foods by nutrient density is more useful than comparing them by calories alone.

6. A student wants a drink for typical daily hydration during a normal school day with no intense exercise planned. Based on the chapter's evidence, which choice best fits their situation?¶
- An energy drink, because caffeine improves hydration efficiency
- A sports drink, because electrolytes are always necessary for hydration
- Water, because sports drinks add unnecessary sugar and calories for typical daily hydration
- Regular soda, since its high sugar content provides quick energy for hydration
Show Answer
The correct answer is C. Water is the reference standard for hydration. Sports drinks add electrolytes and sugar that are useful during prolonged, intense exercise generally over 60 minutes, but they are unnecessary and add empty calories for typical daily hydration. Neither energy drinks nor soda are appropriate substitutes for water in this everyday scenario.

7. A student plans to eat a carbohydrate-heavy snack. Which timing makes this the better choice according to the meal and snack evaluation framework?¶
- About 30 minutes before soccer practice, for fast-access energy
- Right before going to sleep, with no activity planned
- Immediately after waking up regardless of the day's schedule
- Only when paired with another carbohydrate-heavy food
Show Answer
The correct answer is A. Timing fit is one of three questions the chapter's framework asks of any meal or snack: does it match what's coming next? A carbohydrate-heavy snack 30 minutes before soccer practice serves a real physiological purpose by providing fast-access energy, while the same snack before bed with no activity planned does not serve that purpose.

8. During a personal nutrition needs assessment, a student notes they menstruate and follow a vegetarian diet. Which micronutrients should this assessment flag as deliberate-planning priorities?¶
- Only sodium and potassium
- Only vitamin C and fiber
- Only saturated fat and cholesterol
- Iron (from both flags), plus vitamin B12 and zinc (from the vegetarian flag)
Show Answer
The correct answer is D. Menstruating teens commonly face iron gaps, and a vegetarian or vegan diet raises additional risk for vitamin B12, iron, and zinc, since these nutrients are more concentrated in animal products. A rigorous needs assessment identifies these overlapping and distinct risk areas rather than applying one generic recommendation to everyone.

9. Two neighborhoods have similar average incomes, but Neighborhood X has three full-service grocery stores while Neighborhood Y has none, only convenience stores. Based on the food-system pathway described in the chapter, what can you conclude?¶
- Chronic disease rates will be identical in both neighborhoods since income is the only real factor
- Neighborhood Y residents face a direct access barrier to fresh food independent of income, raising chronic disease risk
- Grocery store density has no measurable effect on dietary patterns
- Convenience stores stock the same variety of fresh produce as full-service grocery stores
Show Answer
The correct answer is B. The food-system pathway shows a direct branch from grocery store density to household food choices under constraint, labeled the "direct access effect" — meaning access alone, not just price or income, independently constrains what a household can choose. Lower grocery density in Neighborhood Y creates a structural barrier linked to higher chronic disease risk, even when income is similar.

10. A community group is comparing a mobile produce market to a single-season community garden program to decide which deserves more funding. Which combination of factors reflects the strongest evaluation approach described in the chapter?¶
- Whichever program has the most colorful marketing materials
- Whichever program started most recently
- Reach, sustainability, and cultural fit, evaluated together
- Cost alone, regardless of how many residents are actually served
Show Answer
The correct answer is C. The chapter's evaluation framework for community nutrition initiatives weighs reach (does it serve the highest-need residents), sustainability (does it survive past a single grant cycle), and cultural fit (was it designed with the community's own food traditions in mind). The strongest programs combine all three dimensions rather than relying on a single measure like cost or marketing.
