Why nightshades food checker matters
Nightshades are a plant family including tomatoes, peppers, eggplants, and potatoes. Some people find that avoiding nightshades helps with joint pain, digestive issues, or inflammatory conditions, though research is limited.
- Complete elimination for 30 days gives the clearest picture
- Watch for hidden nightshades in spice blends and sauces

- Goji berries are nightshades
What to know about xylitol
Xylitol (E967, sold in some markets as birch sugar) is graded E for polyols and D on FODMAPs overall, so for a sensitive gut it carries the usual sugar-alcohol load: osmotic water into the bowel, then fermentation. Two things genuinely set it apart from the rest of the sweetener shelf. It is severely toxic to dogs at doses a household pet can easily reach, and it has real dental evidence behind it, because oral bacteria cannot ferment it into acid. That second point is why xylitol turns up in pharmacy chewing gum, toothpaste and mouthwash rather than only in diet food. On the chemical sensitivities it is clean, graded A for histamine, histamine liberation, tyramine, sulfite, nickel, glutamates, gluten, lactose and dairy protein.
Watch for
- Dangerous to dogs.Xylitol triggers a rapid insulin release in dogs, causing a sharp drop in blood sugar within roughly half an hour, and larger doses can cause acute liver failure. Sugar-free gum, mints, some peanut butters and some toothpastes are the usual household sources. This is a veterinary emergency, not a wait-and-see
- Polyols E and low fermentation SIBO E.Dose-dependent bloating, wind and laxation are the human side effect, and the amount in a few pieces of gum is enough for some people
- It hides outside the food diary.Toothpaste, mouthwash, nasal spray, chewable vitamins and liquid medicines are common xylitol carriers, so a log that only records meals can miss the exposure that explains the day
- The dental benefit is specific.It comes from xylitol itself being non-fermentable by oral bacteria, not from a product simply being sugar-free, so a different sugar-free sweetener does not automatically carry the same effect
- It is not the low-FODMAP escape from other polyols.Xylitol and sorbitol are graded identically here at polyols E, so swapping one sugar alcohol for the other changes nothing for the gut
