What snacks can be called green food?

Remove snacks such as plum, melon seeds, potato chips, chocolate, fried, carbonated drinks. These snacks are high in calories and easy to get fat. There are many green foods and many green pollution-free vegetables, but if you want green food snacks, I think fruit and yogurt are. People say that seaweed is a green food, but you can tell by looking at it, right?
