Short answer: gram for gram, guava has about four times the vitamin C of an orange. Here are the numbers, straight from the U.S. Department of Agriculture.

The numbers

According to USDA FoodData Central, 100 grams of raw common guava contains 228 mg of vitamin C. The same amount of raw orange contains 53.2 mg. That makes guava roughly 4.3 times richer in vitamin C by weight.

For context, the FDA's Daily Value for vitamin C is 90 mg. So 100 g of guava, about one medium fruit, provides around 250% of the Daily Value.

Pink guava or Thai guava?

Both are guavas (Psidium guajava). Pink guava is small, fragrant and soft, with pink flesh, and it shines in smoothies and juices. Thai guava is large, crisp and lightly sweet, with white flesh, and most people eat it in slices, like an apple. The USDA figures above are for common raw guava; individual varieties vary.

How to eat guava

Wash it well. The skin is edible.
Thai guava: slice it and eat it crisp, skin and all, or with a pinch of salt and lime.
Pink guava: wait until it smells fragrant and gives slightly to the touch, then eat it as is or blend it.
Keep ripe guava in the fridge and eat it within a few days.
