If there is enough time, I believe I can buy the same amount of fresh fruits and vegetables on the same day. In this way, buying a little every day can ensure diversity, and you don't have to consider too many storage problems. So I often buy a few, mainly fruits and vegetables in season, which are fresh and cheap; Imported fruits, not fruits in the northern season, are generally bought from some fresh apps, and you can shop around. I only buy small packages or well-matched fruits to ensure a week's supply. This can be added at least three times a week, which is both fresh and diverse.
