Most cheeses, particularly aged cheeses and other strong-flavored hard cheeses like mature Cheddar, Roquefort, Stilton, Parmesan, Camembert, Gruyere, and Mozzarella. (If the fruit has been completely cleaned, you may be able to consume it without reacting.) The only safe cheese is bland milk product such as cottage cheese or ricotta. Even though most cheeses are relatively low in histamine when compared with other foods, some varieties can cause problems for certain people. Histamines are released during the aging process of cheeses that become ripe or go bad. As little as 0.5 percent of some cheeses can cause problems for people who are sensitive to this hormone. People who suffer from allergies, autoimmune diseases, asthma, digestive issues, dermatitis, food sensitivities, headaches, IBS, inflammation, migraines, neurological disorders, obesity, and urinary problems should avoid cheeses with histamines because an allergic reaction is likely to occur. The only way to know for sure if a particular cheese is okay to eat is to test it out for yourself. Cheese has long been used by traditional medicine practitioners to treat a wide variety of conditions, including infections, allergies, asthma, arthritis, diabetes, gastrointestinal problems, irritable bowel syndrome, migraines, and urinary problems. In modern times, clinical studies have also shown that eating cheese can help protect people against cancer and cardiovascular disease.
