Sensitivity notes
Why glutamates food checker matters
Glutamates, including MSG, are flavor enhancers found naturally in many foods and added to others. Some people report sensitivity causing headaches, flushing, or other symptoms, though research on 'MSG syndrome' is mixed.
- MSG goes by many names - look for 'glutamate' on labels
- Naturally high in soy sauce, fish sauce, and aged cheeses
- Tomatoes and mushrooms are naturally high in glutamates
- Yeast extract and hydrolyzed proteins contain glutamates
- Fresh, unprocessed foods are generally lower

What to know about casein protein
Casein protein is the slow-digesting fraction of milk, sold as a night-time protein powder because it gels in the stomach and releases amino acids over hours. It is graded high on dairy protein, and that is the point most labels obscure: casein is one of the two proteins (with whey) responsible for cow's milk protein allergy, so a tub marked lactose free or low lactose is still made of the exact molecule a milk allergy reacts to. Residual lactose is graded moderate, low enough that many lactose intolerant people tolerate it and high enough that some do not. On everything else it is clean: no gluten, no FODMAPs, no histamine, no oxalate, no nickel, no caffeine.
Watch for
- Graded high on dairy protein.Lactose free casein is not milk allergy safe, because the allergy is to the protein and casein is the protein
- Moderate residual lactose.Micellar casein and caseinate powders are filtered, not lactose free, so a large night-time serve can still bloat a lactose intolerant gut
- Casein is the milk protein most likely to survive heat and processing, so cooked-in casein in a bar or ready-to-drink shake stays reactive
- Read the tub, not the front label.Blends marketed as slow-release routinely mix casein with whey, and milk protein concentrate and sodium or calcium caseinate are all casein under another name
- Clean on the food chemistry side: no gluten, FODMAPs, histamine, oxalate, nickel or caffeine, so a reaction to it points squarely at the dairy
