Why fructans food checker matters

Fructans are chains of fructose molecules found in wheat, onions, garlic, and many other foods. They're a type of FODMAP that can cause digestive symptoms in sensitive individuals because they're not well absorbed in the small intestine.

  • Garlic-infused oil is low-FODMAP since fructans don't dissolve in oil
  • Green parts of leeks and scallions are lower in fructans
  • Sourdough bread may be better tolerated than regular wheat bread
  • Spelt and ancient grains still contain fructans despite marketing claims
  • Portion size matters - small amounts may be tolerable

What to know about lychee

Lychee grades E for excess fructose and D for polyols, which puts it at E overall on FODMAPs and makes it one of the tropical fruits most likely to produce bloating, wind and loose stools. It also grades E for low-fermentation SIBO protocols. On food chemistry it is mild: low histamine, only a slight liberator effect, low salicylate and low nickel, so a lychee reaction is almost always about the sugars rather than about amines. The other thing people search for is whether lychees are dangerous, after the acute encephalopathy outbreaks reported in litchi-growing regions of India and Vietnam. That risk is specific and worth stating precisely: it involves unripe fruit eaten in quantity by undernourished children who had skipped their evening meal, not ripe lychee eaten as part of a normal diet.

Watch for

  • Very high in excess fructose (E), with more fructose than glucose, so a handful of lychees delivers a fructose load that a sensitive gut absorbs badly
  • High in polyols (D) on top of that, which is what pushes it to E for total FODMAPs.Lychees are also easy to over-eat because they are small and sweet
  • Poor fit for low-fermentation SIBO diets (E), where the combination of fructose and polyols is exactly what those protocols are built to limit
  • Unripe lychee contains hypoglycin A and MCPG, natural compounds that block the body from making glucose from fat.They are the documented cause of hypoglycaemic encephalopathy outbreaks in undernourished children who ate unripe fruit on an empty stomach. Ripe fruit eaten alongside meals is not that scenario, but there is no reason to eat green, unripe lychees
  • Canned lychee in syrup and dried lychee concentrate the sugars, so the processed forms are heavier on fructose than the fresh fruit
