Specific foods do not directly cause an increase in globulin levels. However, consuming a well-balanced diet that includes sources of high-quality proteins can help maintain healthy globulin levels. Good sources of protein include lean meats, poultry, fish, eggs, dairy products, legumes, nuts, and seeds.
