Summary

Colby Jack cheese is a processed food with a relatively clean ingredient list, including pasteurized milk, cheese culture, salt, and enzymes. However, the presence of natamycin as a mold inhibitor introduces a synthetic additive, which slightly detracts from its overall quality. Despite this, the cheese maintains a good balance of protein and fat, making it a reasonable choice within its category.
