Portion Distortion Quiz
Questions: 16 · 10 minutes
1. After months of using a very large bowl, a person is unsure what 1 cup of cereal looks like. What would best recalibrate that estimate?
Fill the bowl to the usual height and call that 1 cup.
Count the individual cereal pieces instead of checking volume or weight.
Measure 1 cup once and observe how it sits in the bowl.
Use the package width as the serving guide.
2. Two snack labels display different serving sizes. What is the most reliable first step when comparing their nutrition information?
Compare only the numbers printed in the calories row.
Choose the product with fewer servings in its package.
Put the values on an equal amount or otherwise account for the serving-size difference.
Assume the physically smaller package has the smaller portion.
3. Your usual portion is larger than the serving size used on a label. What happens to the listed calories and nutrients for the amount you actually eat?
They stay unchanged because labels describe the entire food product.
Only calories increase; all other nutrient amounts stay fixed.
They should be scaled in proportion to the number of labeled servings eaten.
They decrease because a larger portion spreads the nutrients out.
4. What is “unit bias” in the context of portion distortion?
The tendency to treat one package, item, or container as the appropriate amount even when it contains multiple servings
The belief that foods measured in grams contain no calories
The requirement that every meal contain one unit from each food group
The difference between metric and customary measuring systems
5. A cereal label defines one serving as 1 cup. You pour 2 cups into a bowl. How many labeled servings is that?
Half a serving
One serving
The number cannot be determined without knowing the bowl size.
Two servings
6. What is the clearest distinction between a portion and a serving size?
A portion applies only to meals, while a serving size applies only to packaged snacks.
A portion is the amount someone chooses to eat, while a serving size is a stated reference amount.
A portion is always smaller than the serving size shown on a label.
A portion is measured by volume, while a serving size is measured only by weight.
7. Why can a larger plate contribute to portion distortion?
Food contains more calories after it is transferred to a larger plate.
The same amount may look smaller on it, making a larger helping seem more typical.
Plate diameter determines the serving size used on food labels.
A larger plate makes every food less filling, regardless of quantity.
8. A drink bottle lists 2 servings per container. If you drink the whole bottle, how should you interpret the listed calories and nutrients?
Multiply the listed amounts by 2.
Use the listed amounts once because the bottle is a single package.
Divide the listed amounts by 2 because the serving size is smaller than the bottle.
Use the listed calories once but double only the nutrients.
9. Two bowls have different shapes and capacities. What is the most dependable way to learn how much cereal your usual fill level holds?
Judge by which bowl looks fuller from above.
Assume the taller bowl always contains more.
Count both bowls as one serving because each is a single dish.
Measure the usual amount with a cup or scale and compare it with the label.
10. Someone automatically refills a bowl before noticing whether the first portion was satisfying. Which action would best test whether more food is actually wanted?
Use a larger bowl so no refill is necessary.
Match the amount eaten by everyone else at the table.
Treat each refill as a separate meal regardless of timing.
Pause after the first portion and check current hunger before deciding.
11. Which familiar object is commonly used as a rough visual cue for about 3 ounces of cooked meat?
A standard smartphone
A tennis ball
A teaspoon
A deck of playing cards
12. Why is a single “perfect portion” unlikely to suit every person and situation?
Serving sizes on labels are individualized for whoever buys the product.
Visual portion cues become exact once someone uses them regularly.
Needs and appetites can differ with factors such as body size, activity, age, health, and meal context.
Every person needs the same amount of food, but plate sizes make it look different.
13. Two foods occupy the same volume: water-rich vegetables and a fried snack. Which statement best reflects energy density?
The fried snack will generally provide more calories in the same volume.
Equal food volumes always contain equal calories.
The vegetables will generally provide more calories because they contain more water.
Energy density describes package size rather than calories relative to food weight or volume.
14. A package contains 4 servings at 120 calories per serving. You eat half the package. How many calories does that represent?
240 calories
120 calories
360 calories
480 calories
15. A restaurant entrée looks much larger than the amount you intended to eat. Which response most directly limits the effect of that oversized serving?
Assume the restaurant has already defined it as one standard serving.
Set aside or box the amount you do not intend to eat before continuing.
Eat more quickly so the food does not influence later choices.
Skip an earlier meal whenever you expect a large restaurant entrée.
16. What is the main limitation of estimating food portions with familiar objects or your hand?
The method works only for foods that come in packages.
Object and hand sizes vary, so these cues provide estimates rather than exact measurements.
Visual cues measure calories directly but not food volume.
Every object comparison corresponds to an exact legal serving size.
