SIBO Lactose retest and Mannitol test
I tested for lactose again, just because I suspect that was the cause of the whole issue. I ended up making some blueberry buckles - basically, muffins that don't really hold together, with a side of the Tillamook ice cream. I had less than a cup of ice cream, and suffered no ill effects. I really doubled down with some homemade gluten free macaroni and cheese, made with freshly grated cheese and whole milk. Of course, it made more than one serving, so I likely only consumed about a half a cup of milk.
Still no pain or issues! What a success!
Yesterday, I decided to throw caution to the wind and make a Chinese pork noodle dish with fresh shiitake mushrooms. Something high in mannitol that I hadn't yet properly tested. However, I've been eating mushrooms for years without ill effects, and when I was eating vegan, I ate a lot of them, especially portabellas. The recipe called for 10 ounces of mushrooms, and like the mac and cheese recipe, I only ate probably 2 ounces, likely a normal serving for normal people that aren't affected by mannitol.
And still - no pan! I feel great, which is wonderful! Hopefully this keeps up. It's so nice to have more options in my diet.
I'll likely continue to keep my lactose intake pretty low going forward, but I'm pleased that I don't have to swear off lactose completely!
