Green kiwifruit (Actinidia deliciosa), most commonly the Hayward variety, is a sweet-tart fruit with vibrant green flesh, tiny edible black seeds, and a fuzzy brown skin. Two kiwifruit provide an excellent source of vitamin C along with fiber, vitamin K1, vitamin E, lutein, polyphenols, and the protein-digesting enzyme actinidin. Green kiwifruit has been particularly well studied for digestive health, with human clinical trials showing benefits for bowel regularity and gastrointestinal comfort. Enjoy kiwifruit on its own or add it to yogurt, breakfast bowls, smoothies, fruit salads, green salads, and salsas.
