Explanation:

The 5/20 rule in nutrition states that a nutrient is considered "low" if its % Daily Value (DV) is 5% or less, and "high" if its % DV is 20% or more. We analyze each nutrient:

Step 1: Identify nutrients with ≥20% DV (high)

• Sodium: 20% DV.
• Calcium: 20% DV.

Step 2: Identify nutrients with ≤5% DV (low)

• Dietary Fiber: 0% DV.
• Vitamin A: 4% DV.
• Vitamin C: 2% DV.
• Iron: 4% DV.
• Saturated Fat: 15% (not low, 15>5), Total Fat: 18% (not low), Cholesterol: 10% (not low), Total Carbohydrate: 10% (not low), Sugars: no DV, Protein: no DV.

Step 3: Summarize

• High in Sodium (20% DV) and Calcium (20% DV).
• Low in Dietary Fiber (0% DV), Vitamin A (4% DV), Vitamin C (2% DV), and Iron (4% DV). Also, check total amounts: For a 2000 - calorie diet, daily limits: Total Fat <65g, Sat Fat <20g, Cholesterol <300mg, Sodium <2400mg, Total Carb <300g, Fiber 25g. Per serving: Total Fat 12g (12/65≈18% of daily max), Sat Fat 3g (3/20 = 15% of daily max), Cholesterol 30mg (30/300 = 10% of daily max), Sodium 470mg (470/2400≈19.6% of daily max), Total Carb 31g (31/300≈10.3% of daily max), Fiber 0g (0/25 = 0% of daily max). So in terms of daily limits (not just % DV), Sodium is close to 20% of daily max (470/2400≈20%), Calcium is 20% DV (good source), Fiber is very low (0g), Vitamins A, C, Iron are low.

Answer:

• High (≥20% DV): Sodium (20% DV), Calcium (20% DV).
• Low (≤5% DV): Dietary Fiber (0% DV), Vitamin A (4% DV), Vitamin C (2% DV), Iron (4% DV).

(For daily intake context: Sodium per serving is ~20% of 2400mg limit, Calcium meets 20% of daily need; Fiber is 0% of 25g daily need, Vitamins A/C/Iron are ≤5% of their daily needs.)
