Most people peel their kiwi without thinking twice. But according to nutritionists, that fuzzy skin you're tossing? It's packed with nutrients you're throwing away.
Turns out, this humble $0.49 fruit might be one of the most underrated additions you can make to your diet, especially if you keep the skin on.
We spoke with Nicolle Cucco, a nutrition expert at Muscle Booster, to break down why kiwi deserves more credit and what happens when you eat the whole thing, fuzz and all.
"Kiwi is one of the most underrated fruits when it comes to nutritional value," Cucco explains.
"Not only is it rich in vitamin C, fiber, and antioxidants, but it also contains a unique enzyme called actinidin, which plays a key role in aiding digestion. It's a small fruit, but it delivers big benefits."
That enzyme, actinidin, is what sets kiwi apart from other fruits. It actively helps your body break down protein, which is why some people eat kiwi after a heavy meal.
But the benefits go far beyond digestion.
Beyond actinidin, kiwi is high in fiber, especially when you eat the skin. "It's a fantastic option for anyone dealing with bloating or sluggish digestion," says Cucco. If you've felt uncomfortably full after meals, kiwi might be worth trying as a natural digestive aid.
Kiwi is one of the few fruits that naturally contains serotonin, a hormone that regulates mood and sleep.
"Some studies even show that eating kiwi an hour before bed can lead to falling asleep faster and enjoying deeper rest," Cucco notes. If you've been struggling with sleep quality, this might be a simple, tasty fix.
One kiwi gives you more than 100% of your daily vitamin C, and that matters for your skin.
"Vitamin C helps boost collagen production, which is essential for maintaining firm, youthful skin," Cucco explains. "The antioxidants also help fight free radicals that can age your skin prematurely."
That vitamin C has another benefit: it supports your immune system.
"Just one kiwi can give you more than your recommended daily intake," says Cucco. "That makes it a powerful ally for your body, helping fight off colds and infections more effectively."
Kiwis are rich in potassium and fiber, both of which support cardiovascular health.
"Potassium helps regulate blood pressure, while fiber helps lower cholesterol levels—a double win for your heart," Cucco points out.
At around 42 calories per fruit, kiwi is both low in calories and high in fiber.
This combination helps you feel full longer. "That makes them a smart snack if you're trying to manage your weight or curb cravings throughout the day," says Cucco.
Here's where things get interesting. That fuzzy skin most people peel off? It's actually where a lot of the fiber, antioxidants, and nutrients live.
"Most people instinctively peel their kiwi, but what they don't realize is that the fuzzy skin is actually packed with additional fiber, antioxidants, and nutrients," Cucco explains. "If you can get past the texture—which, for some, is similar to a peach—eating the whole fruit, skin and all, is one of the best ways to maximize its health benefits."
In other words, by peeling your kiwi, you're essentially cutting the nutritional value in half.
If the fuzz bothers you, try rubbing it gently with a towel first or choosing gold kiwis, which have smoother skin.
If you're active or training regularly, kiwi can fit neatly into your routine. "Its quick-digesting natural sugars provide an energy boost pre-workout, while the vitamin C and anti-inflammatory properties support recovery afterwards," says Cucco.
It's also hydrating and rich in antioxidants, which can help reduce muscle soreness and oxidative stress from intense exercise. Whether you're just getting started with fitness or training consistently, kiwi delivers nutrients your body can actually use.
At less than 50 cents per fruit, kiwi is one of the most affordable ways to boost your vitamin C intake, improve digestion, and support better sleep. And if you eat it with the skin on? You're getting even more fiber and antioxidants for your money.
It's simple, accessible, and packed with benefits. No wonder it's finally getting the recognition it deserves.
