A student records their intake for three days. Day 1: 1 cup cooked oats (4 g fiber) + 1 apple (4 g). Day 2: 1 cup lentils (15 g) + 1 banana (3 g). Day 3: sandwich with whole-wheat bread (2 slices, 4 g) + mixed salad (2 g). What is the average daily fiber intake across the three days, and is this likely to meet a commonly cited recommendation of ~25 g/day for general adult benefits?

• A. Average ≈ 25 g/day, which meets the recommendation and should be sufficient to confer benefits for most adults.
• B. Average ≈ 32 g/day, exceeding most recommendations and likely to cause nutrient malabsorption and gastrointestinal distress.
• C. Average ≈ 10.7 g/day, which is substantially below the common 25 g/day benchmark and thus unlikely to provide full expected benefits.
• D. Average ≈ 18 g/day, which is marginally adequate to relieve constipation but insufficient for reducing long-term disease risk.

Answer: (C)
