Kiwi (Actinidia deliciosa, Actinidia chinensis)

background

Kiwi contains high amounts of vitamin E, serotonin, and potassium, and it is known to have the highest density of vitamin C among all fruits. It is also low-fat, cholesterol-free, and believed to be a good source of folic acid. However, even with these possible benefits, kiwi has been linked to a growing number of reports of allergies.
Kiwi is believed to have antioxidant effects and has been used to protect against lung problems and to improve heart health. However, high quality evidence supporting the use of kiwi in humans is lacking. More research is needed.

evidence table

These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
 
Allergy (Grade: C)
Early research has looked at the effects of kiwi extract on measures of allergic sensitivity in humans. More research is needed before conclusions can be made.
Antioxidant (Grade: C)
Early evidence shows that adding kiwi to the Western diet may improve antioxidant status and other heart health indicators in healthy people. More research is needed before conclusions can be made.
Blood pressure control (Grade: C)
Limited evidence shows that eating three kiwi fruits daily may lower blood pressure. However, results are conflicting, and more research is needed before conclusions can be made.
Constipation (Grade: C)
Early research suggests that kiwi extract may promote bowel movements and improve quality of life in elderly people with constipation. Some research found that a freeze-dried kiwi extract called Zyactinase® may help relieve constipation, while other research reported that it may promote healthy gut bacteria. However, firm evidence is still needed before conclusions can be made.
Energy enhancement (Grade: C)
Early research suggests that a drink that contains kiwi may improve athletic performance. However, high-quality evidence is needed before conclusions can be made on the effectiveness of kiwi for improving energy.
Respiratory problems (Grade: C)
Kiwi has been used to protect against respiratory illness and to increase lung function. A survey found that kiwi and other fruits high in vitamin C may benefit children who have lung conditions such as wheezing. However, high quality evidence supporting the use of kiwi for lung conditions is lacking. More studies are needed before conclusions can be made.
Skin rash (Grade: C)
Human research found a lack of effect of kiwi extract in people who had chronic skin rashes. More research is needed.
