Blue cheese is rich in nutrients and offers various health benefits. It is high in calcium, with a one-ounce serving containing 150 mg of calcium. Regular consumption of calcium-rich foods like blue cheese can help maintain healthy bone density and reduce the risk of osteoporosis. The calcium in blue cheese may also help prevent obesity by reducing body fat and maintaining gut health. Additionally, blue cheese contains spermidine, a compound that may delay aging and reduce the risk of cardiovascular disease by positively affecting cardiac muscle cells. Blue cheese is also a good source of protein. However, it should be consumed in moderation due to its high salt and saturated fat content. People prone to headaches or migraines may want to limit their intake of blue cheese.
