Health Benefits Of Kiwi Fruit
Most of the kiwifruit’s benefits come from its high concentrations of nutrients and phytochemicals. Eating this fruit can help your body in the following ways:
Improve Skin Health
Collagen is a key player in skin strength and elasticity, making it an important factor in skin health. Kiwi is high in collagen-promoting vitamin C, which contributes to healthy skin (17). Vitamin E found in the fruit nourishes the skin from within, helping to keep it soft and supple.
A Powerful Source Of Antioxidants
Many of the phytochemicals found in kiwifruit are powerful antioxidants (16). Kiwi’s high concentration of vitamin C, lutein and zeaxanthin help protect your body against harmful free radicals that contribute to chronic diseases like heart disease and cancer.
Promote Healthy Blood Sugar Levels
Kiwi contains a fiber compound called “chitin,” which slows the rate at which sugar enters the bloodstream (2). This helps prevent blood sugar spikes that can lead to insulin resistance, metabolic syndrome, diabetes and heart disease.
Promoting Weight Loss
Kiwi’s high fiber content makes it an ideal snack for weight loss (16). Additionally, kiwifruit is low in calories and rich in water, which boosts satiety. Eating this fruit between meals can help keep you full and decrease late-night snacking that results in weight gain.
Due to its high concentration of magnesium, kiwifruit can help promote sleep by calming the nervous system and relaxing muscles. Magnesium deficiencies have been linked with insomnia, so consider adding a few slices of this tasty fruit into your diet for sweet dreams (7).
The fiber in kiwifruit may improve heart health by lowering total cholesterol and improving the ratio of harmful LDL to beneficial HDL cholesterol (4). This fruit is rich in potassium, which helps protect against stroke risk. Additionally, it’s a good source of magnesium, which relaxes the blood vessels to reduce blood pressure (5).
Most people can benefit from kiwifruit’s blood pressure-lowering effects. Research links a higher consumption of fruits with a decrease in blood pressure (6). Kiwi is also rich in potassium, which reduces blood pressure by countering the effects of sodium.
Kiwi benefits the kidneys by balancing pH levels and reducing kidney-damaging acids (3). This fruit can also help increase fluid intake, which helps combat frequent urination that occurs with conditions like diabetes and urinary tract infections (UTIs).
Regularly eating kiwi may decrease your risk of certain cancers. The fruit is a good source of antioxidants that can help fight free-radical damage to cells, decreasing the risk for cancer and other conditions (15). Kiwifruit also contains lutein, which has been linked with decreased cancer risk due to its ability to protect cell membranes from DNA damage (1).
In addition to kiwifruit’s many health benefits, it can also be used as a natural remedy for several conditions and disorders.
The anti-inflammatory properties of vitamin C found in kiwi fruit have been shown to help relieve arthritis symptoms (19). Eat a few slices of this fruit to help fight inflammation and ease pain.
Kiwifruit helps reduce acid reflux symptoms by decreasing the release of stomach acids while increasing the production of mucus in the stomach (18). This fruit’s fiber can also speed up digestion, helping prevent heartburn. Additionally, kiwi contains potassium, which helps balance electrolytes in the body to reduce heartburn symptoms.
Kiwi is rich in vitamin C and the mineral manganese, both of which help support bone health. Vitamin C helps decrease fracture risk by strengthening collagen and promoting healing after a bone injury. Manganese is needed for proper bone formation (13). Kiwis contain both nutrients in a single delicious snack.

How To Pick A Kiwi Fruit
When choosing a kiwifruit, look for one that is plump with taut skin—avoid shriveled fruits or those with dents or bruises. Kiwifruit can be stored in the refrigerator for up to two weeks before cutting and eating. However, exposing the fruit to oxygen speeds up spoilage, so it is best consumed shortly after purchase
Kiwi Side Effects
Although kiwi is considered safe by most major health organizations, there are some minor side effects to be aware of (14).
Interaction With Beta-Blockers
Individuals who take drugs containing beta-blockers for high blood pressure should avoid eating this fruit or at least cut back on their dosage if they eat kiwi together. Beta-blockers slow heart rate and decrease blood pressure, so adding kiwi to the mix could have a negative effect.
These drugs can cause potassium levels to rise in the blood, which can lead to potentially dangerous heart rhythm abnormalities.
Interaction With Warfarin
Kiwi interacts with the anticoagulant (blood-thinning) drug warfarin and increases its effects, so those taking this drug should limit their intake of kiwifruit. However, it is possible for some individuals to eat kiwi without experiencing negative effects.
Contact your doctor if you take warfarin and want to add kiwi to your diet, as this may require a dosage adjustment.
Interaction With Diuretics
Kiwi is a natural source of potassium, so those on diuretic drugs that work by removing excess potassium from the body should avoid this fruit. Kiwifruit can cause a dangerous rise in these drugs’ effects, or a decrease in potassium levels that may be already low from the diuretic medication.
The fruit may also cause allergic reactions in people sensitive to latex.
Though not common, if you experience tingling or numbness in the mouth after eating kiwi, see your doctor. This could be an early sign of exposure to toxic alkaloids found in certain species of plants like the silverleaf nightshade (Solanum elaeagnifolium) or box elder (Acer negundo).
Kiwi is a great fruit to enjoy year-round. To maximize the nutritional benefits, eat organic varieties that have not been sprayed with pesticides and chemicals.
You can eat this fruit in a variety of ways, including fresh, dried or juiced. Kiwi also pairs well with green tea and mint, which can help to minimize any unpleasant breath odor.
