Explanation:

The 5/20 rule states that a nutrient is "low" if its % Daily Value is 5% or less, and "high" if it's 20% or more. We analyze each nutrient:

Step 1: Analyze Total Fat

Total Fat: 18% (between 5% and 20%, not low or high by strict 5/20 for high/low, but 18% is close to 20%, moderate)

Step 2: Analyze Saturated Fat

Saturated Fat: 15% (moderate, between 5% and 20%)

Step 3: Analyze Trans Fat

Trans Fat: No % Daily Value (but amount is 3g; for a 2000 - calorie diet, max trans fat should be very low, so 3g is relatively high as trans fat is unhealthy in any significant amount, but by 5/20 rule (which is for %DV), since there's no %DV, we note it.

Step 4: Analyze Cholesterol

Cholesterol: 10% (moderate, between 5% and 20%)

Step 5: Analyze Sodium

Sodium: 20% (this is "high" as it meets the 20% threshold for "high" nutrient)

Step 6: Analyze Total Carbohydrate

Total Carbohydrate: 10% (moderate, between 5% and 20%)

Step 7: Analyze Dietary Fiber

Dietary Fiber: 0% (this is "low" as it is 5% or less)

Step 8: Analyze Sugars

Sugars: No %DV (but amount is 5g; for a 2000 - calorie diet, the recommended sugar intake is about 50g per day, so 5g per serving is 10% of that, but by 5/20 rule (for %DV), since there's no %DV, we note it.

Step 9: Analyze Protein

Protein: No %DV (so 5/20 rule doesn't apply here as %DV is not given)

Step 10: Analyze Vitamins and Minerals

• Vitamin A: 4% (low, 5% or less)
• Vitamin C: 2% (low, 5% or less)
• Calcium: 20% (high, 20% or more)
• Iron: 4% (low, 5% or less)

Answer:

• Low nutrients (≤5% DV): Dietary Fiber (0%), Vitamin A (4%), Vitamin C (2%), Iron (4%)
• High nutrients (≥20% DV): Sodium (20%), Calcium (20%)
• Moderate nutrients (5 - 20% DV): Total Fat (18%), Saturated Fat (15%), Cholesterol (10%), Total Carbohydrate (10%)
• No %DV (so 5/20 rule not applicable): Trans Fat, Sugars, Protein

(If you want a summary of the 5/20 analysis: Nutrients with ≤5% DV are low (Dietary Fiber, Vitamins A, C, Iron), ≥20% DV are high (Sodium, Calcium), and others in 5 - 20% are moderate. Trans Fat, Sugars, Protein lack %DV for 5/20 analysis.)
