Summary

The presence of synthetic additives such as phosphoric acid, artificial flavors, and potassium sorbate contributes to its processing level and raises concerns about potential health impacts. While it provides a good source of protein, the use of artificial ingredients and preservatives detracts from its overall healthiness.
