THE HUMBLE KIWI: A SUMMER SUPERFRUIT HIDING IN PLAIN SIGHT

When summer hits, the fruit bowl tends to fill with familiar favorites. Watermelon. Berries. Stone fruit.

But what should really be among them is a small, fuzzy powerhouse with outsized benefits: the kiwi.

The health benefits of kiwi fruit are immense.

Both green and golden kiwis offer incredible nutrient density in a tiny package.

Kiwis are one of the best summer superfoods for digestion, skin and immune support.

And depending on which variety you choose, you're getting a slightly different but equally powerful boost to your health.

WHAT ARE THE HEALTH BENEFITS OF KIWI FRUIT? Kiwis support digestion, immunity, and antioxidant protection. Green kiwis are high in fiber, while golden kiwis are rich in vitamin C and polyphenols that may restore gut health after antibiotics.

GREEN KIWI VS. GOLDEN KIWI: MORE THAN MEETS THE EYE

Green kiwis are fiber-rich and tart. Golden kiwis are smoother, much sweeter, and less acidic.

The difference isn’t just taste. It’s structural.

Green kiwis deliver around 2 grams of fiber per fruit, making them an excellent ally for digestion and gut health. They also contain a natural enzyme called actinidin, which aids protein breakdown and supports motility.

Golden kiwis, on the other hand, are the product of years of careful breeding.

Zespri’s patented SunGold variety is now a golden trademark—valued for its tropical flavor, vibrant color, and impressive nutrient profile. Though they come at a slightly higher price point, goldens are worth the upgrade.

THE VITAMIN C POWERHOUSE (THAT'S NOT AN ORANGE)

We tend to think of oranges as the go-to source for vitamin C.

But there’s a twist because kiwis outpunch oranges in the vitamin C department.

A single kiwi contains twice as much vitamin C as an orange—about 160mg versus 70mg.

One golden kiwi can cover more than 200% of your daily needs—supporting immune resilience, collagen production, and oxidative stress repair, all in one fruit.

Pair that with a kiwi’s unique polyphenol profile, and you’ve got something special.

WHAT SETS KIWIS' ANTIOXIDANTS APART

Each kiwi contains between 50 to 100mg of polyphenols, depending on the variety.
These include powerful compounds like quercetin, caffeic acid, and chlorogenic acid—all known for their anti-inflammatory, blood sugar-regulating, and brain-protective effects.

And in a standout study, kiwi polyphenols were found to completely restore the gut microbiome after antibiotic disruption—making kiwi one of the few foods shown to help rebalance the gut on a cellular level.

Kiwis also appear on our list of flu-busting essentials for the winter.

They’re not just snacks. They’re recovery tools.

EASY, PORTABLE & VERSATILE

Kiwis are one of the simplest whole foods to keep on hand.

They require no prep beyond slicing (or scooping, or biting into if you’re team skin-on).
They pair effortlessly with yogurt, cottage cheese, or summer salads. Some say you can use kiwi as a natural meat tenderizer, thanks to its enzymatic activity.

Whether you’re looking to support gut health, tame inflammation, or just swap a sugary dessert for something real—kiwis are a no-fuss, high-impact option.

And this summer? They deserve a permanent place on the table.

The only note of caution: Kiwis are histamine liberators.

Be aware of overdoing it and overconsuming kiwis because they are known to be histamine liberators. This means they can trigger the release of histamine from your own mast cells—even if they aren’t high in histamine themselves.
