Yes, there are polymers that can be eaten. In fact, we consume a lot of polymers daily without even thinking about it. Don’t be surprised. Think of a chicken burger. Chicken contains a lot of protein and the bun contains starch. Both protein and starch are polymers.
Proteins make up a major chunk of our body; it constitutes organs, muscles and fingernails. Milk, eggs, meat, seeds and nuts are protein rich foods. Starch is a polysaccharide with high molecular weight. Our body breaks down starch into glucose which gives us energy to work and play. In short, polymers give us energy to do everything. Foods like corn, potatoes and bread are rich in starch.
Cellulose is also present in vegetables and grains, but we cannot digest it.
