Sure thing ! Proteins and complex carbohydrates are proteins, and they’re consumed on a daily basis. Vegetables like potatoes are packed with starch, which is a polymer of glucose, same goes for pasta and bread (which also contains quite a bit of protein to help develop the dough when it is kneaded)
DNA is another polymers you regularly consume, purely because it is in all the cells that are in the food you eat.
If you were thinking about plastics, I don’t think so – although if it was possible there’d be much less cleaning up to do!
