Yes, it is, because cheese contains a rich source of protein, which contributes to muscle building. According to Hermans WJH et al., in Cheese Ingestion Increases Muscle Protein Synthesis Rates Both at Rest and During Recovery from Exercise in Healthy, Young Males: A Randomized Parallel-Group Trial showed that Eating cheese enhances muscle protein synthesis rates both at rest and during recovery from exercise. The post-meal muscle protein synthetic response to consuming cheese or milk protein remains consistent when 30g of protein is consumed either at rest or during recovery from exercise in healthy, young males.
