The nutrition profile of passion fruit means it has some great health benefits.
It's a Rich Source of Antioxidants
Antioxidants protect your body from free radicals, unstable molecules that can damage your cells when they are present in large numbers (4).
Passion fruit contains a lot of antioxidants.
In particular, it's a rich source of vitamin C, beta-carotene and polyphenols.
Polyphenols are plant compounds that have a range of antioxidant and anti-inflammatory effects. This means they may protect against chronic inflammation and diseases like heart disease and cancer (2, 5, 6).
Vitamin C is an important antioxidant that you need to get from your diet. It helps support a healthy immune system and healthy aging (7, 8, 9, 10, 11).
Beta-carotene is also an important antioxidant. In your body, it is converted to vitamin A, which is essential for preserving good eyesight.
Diets that contain lots of beta-carotenes from plant foods have been linked with a lower risk of some cancers. These include prostate, colon, stomach and breast cancer (12, 13, 14, 15, 16, 17).
It's a Good Source of Dietary Fiber
A single 18-gram serving of passion fruit contains around 2 grams of fiber, most of which is soluble fiber.
This is quite a large amount for such a small fruit.
Fiber is important for keeping your gut healthy and preventing constipation, yet most people don't eat enough of it (18).
Soluble fiber helps slow the digestion of your food, which can prevent blood sugar spikes (19).
Diets that are high in fiber are also associated with a lower risk of diseases including heart disease, diabetes and obesity (20).
