Question

Which food item is rich in protein?
raw vegetables
cheese
bacon
nuts
eggs

Answer 1

Nuts are very rich in protein, although eggs are also a good source of protein... So either one

Answer 2

They are all rich in protein, just in different amounts. You would need to look up each of them to see which has the most protein, but they all have protein is the point.
Although, I think the Bacon would have the most. Most to least based on daily value: Bacon, Cheese, Eggs, Nuts, Raw vegetables.
