Notable compounds in each

When to choose each

Kiwifruit edges ahead on nearly every number here, a little more protein and fibre, and slightly less sugar and fat, though the margins are mostly small. Orange is virtually sodium-free and remains the more iconic vitamin C fruit by reputation, even though kiwifruit is, gram for gram, at least as concentrated a source. Both are excellent low-calorie fruit choices; kiwifruit’s edible skin, yes, it’s edible, if you don’t mind the fuzz, adds a bit more fibre than most people realise.

Common questions

Is kiwifruit really as high in vitamin C as orange? Yes — gram for gram, kiwifruit is at least as concentrated a source of vitamin C as orange, and by some measurements higher, despite orange’s much stronger reputation for the nutrient.

Can you eat kiwifruit skin? Yes — kiwifruit skin is edible and adds extra fibre, though the texture puts most people off eating it whole. Rubbing off some of the fuzz first, or choosing a smoother-skinned variety, makes it easier to manage if you want the fibre benefit.
