Explanation:

Question 17 (Nutrition Myths)

• "All carbohydrates should be avoided for weight loss" is a myth (complex carbs are healthy).
• "Fat in foods directly leads to body fat gain" is a myth (calorie balance matters more).
• "Individual variability affects nutritional needs" is evidence - based (e.g., age, activity, health vary needs).
• "Supplements are necessary for everyone" is a myth (most get nutrients from food).

• Dietary fiber promotes gut health (feeds good bacteria).
• It helps regulate blood sugar (slows carb absorption).
• It supports healthy cholesterol levels (binds to cholesterol).
• Fiber is not a quick energy source (unlike simple carbs); quick energy comes from carbs like glucose.

Step1: Recall MyPlate proportions. MyPlate recommends protein (and grains) each take about 25% (or 20 - 30%) of the plate.

Step2: For a 10 - inch plate, 20% of 10 inches is $0.2\times10 = 2$ inches, 30% is $0.3\times10 = 3$ inches. The standard MyPlate has protein as about a quarter (25%) or ~2 - 3 inches. The 2 - inch (20%) option aligns with the lower end of the recommended protein portion (protein and grains each ~25%, veggies ~50%, fruits ~25%? Wait, correct MyPlate: veggies (45 - 50%), grains (25%), protein (25%), fruits (25%)? Wait, no, the visual is: veggies and fruits (half), grains (quarter), protein (quarter). So for a 10 - inch plate, quarter of 10 is 2.5 inches, close to 2 or 3. But the options: 2 inches (20%), 3 inches (30%). The MyPlate protein portion is about 25%, so 2.5 inches, closest to 2 inches (20%) or 3 inches (30%)? Wait, maybe the question considers protein as 20 - 30%, and 2 inches is 20% of 10. Let's calculate: 2 inches is 2/10 = 20%, 3 inches is 30%. MyPlate's protein section is about a quarter (25%), so 2.5 inches. The option 2 inches (20%) is the closest among the given (since 20% is close to 25% in the options).

Answer:

Individual variability affects nutritional needs
