Which food do you think will take a longer time to get digested - sugar or beans (beans contain a lot of proteins) why?

Beans will take longer to get digested. Sugar is carbohydrate which is converted to its absorbable form, i.e., glucose whereas beans contain proteins. Proteins are a long complex chain of amino acids. For proteins to get digested, they first need to be broken down into simpler forms, i.e., amino acids. Therefore, beans will take a longer time to get digested.
