What are the convenient and healthy foods? Please summarize.

Many snacks sold in shops are convenient to eat, but they contain a lot of additives, which makes people who usually pay more attention to health very embarrassed and don't know how to choose. In fact, there are quite a lot of convenient and healthy foods, but many people have never thought of it this way, such as boiled eggs, which can be eaten without shell; For example, pure milk can be drunk through a straw; For example, bananas can be eaten after peeling, and so on. There are many original melon seeds, cucumbers, tomatoes, etc., so I won't give examples one by one.
