Is there any nutritional difference between eating kiwi fruit hard and soft? I feel there is no difference because it is the same substance and the same fruit. It's just that if you eat it hard, it may taste a little astringent and a little sour. If you eat it soft, it will be sweeter and less astringent because it is completely ripe. So I think it’s better to eat soft ones, but you should eat them as soon as they get soft, otherwise they will break easily.
