Pix, I’ve switched to the much shorter-cooked meat broth, and it’s made a big difference for me. To avoid the high histamine issue, cook the meat with bones for less than 2 hours. I then immediately freeze the meat in meal-sized portions, and it’s helped a lot!
Remember, histamine isn’t like an allergy, it’s more like a bucket. When the bucket is full, you experience symptoms. So if you had the beef stock before the chicken stock, the latter could be what pushed you over the edge.
