Sure! Histamines are tricky! It's best to get a list to guide you, but basically most fresh foods are low histamine. Anything that is aged, cured, fermented, smoked, long cooked or reheated develops histamines. Many people get allergy type symptoms from them and often people with seasonal allergies find they improve with a low histamine diet as it reduces the overall allergy load. Some fresh foods are high though like eggs, avocado, banana.
