A selected equal-weight ranking
Per 100 g edible raw fruit, USDA SR Legacy gives guava 228.3 mg vitamin C, SunGold kiwifruit 161.3 mg, green kiwifruit 92.7 mg, papaya 60.9 mg, strawberries 58.8 mg and orange 53.2 mg. Guava leads this set. This is not an exhaustive world ranking and does not include every unusually concentrated fruit or powder. [1]
Why a per-fruit ranking can change
A whole orange, a handful of berries and one guava do not necessarily have the same edible mass. Choose either equal weights or realistic portions, and label the denominator. The SunGold record identifies a particular cultivar; assigning it to all gold kiwifruit would overstate what the record shows. Historic averages also do not measure the fruit on a particular plate. [1]
A hypothetical equal-weight fruit bowl
For 50 g portions, multiply each per-100-g value by one half. Guava gives about 114.15 mg, green kiwi 46.35 mg and orange 26.6 mg. The comparison answers a nutrient-composition question, not which single fruit should replace all others. Different fruits contribute other nutrients and dietary variety. [1]
