Why gos food checker matters
Galacto-oligosaccharides (GOS) are carbohydrates found mainly in legumes and some vegetables. They're a FODMAP that can ferment in the gut, causing bloating and discomfort in sensitive people.
- Canned and rinsed legumes are lower in GOS than dried
- Start with smaller portions and build up tolerance
- Some people find beano-type enzymes helpful
- Firm tofu is lower in GOS than silken tofu
- Sprouted legumes may be better tolerated

What to know about tung oil
Tung oil is not a food, and that is the entire point of this page. It is pressed from the nut of Vernicia fordii and used as a wood finish, valued because it polymerises on contact with air into a hard, water resistant film. It is in this database because it appears in ingredient lists and because people searching for it are usually asking one specific question: whether a tung oil finish on a chopping board or a wooden bowl is safe for food contact. That is a genuinely reasonable question with a genuinely nuanced answer. What it is not is a cooking oil, and it should never be swallowed.
Watch for
- Do not ingest it.Tung oil is a drying oil, not an edible one, and swallowing it causes gastrointestinal upset, vomiting and diarrhoea. There is no culinary use and no quantity that is intended to be eaten. The swap suggestions on this page are edible oils offered for anyone who arrived here looking for one, not equivalents.
- The food contact question turns on curing.Pure, fully cured tung oil is widely regarded as food safe for wooden surfaces once it has polymerised, which takes days to weeks rather than hours. Uncured oil is not, and rushing the cure is the actual mistake people make.
- Most products sold as tung oil are not pure tung oil.Tung oil finish typically contains petroleum distillates and metallic driers, and those additives are the reason a given tin may not be food safe even when the base oil would be.
- Vernicia is in the Euphorbiaceae, the spurge family, and so is a relative of the castor bean rather than of any culinary nut.The word nut in tung nut is misleading in exactly the way that matters.
- It is not a tree nut allergen in the labelling sense, since it is not a food, but the residue question on a finished surface is worth raising with an allergist rather than assuming.
