Why lectin food checker matters

Lectins are proteins found in many plant foods, especially legumes and grains. Some people follow low-lectin diets believing they reduce inflammation and digestive issues, though properly cooked foods have reduced lectin content.

  • Proper cooking destroys most lectins - never eat raw beans
  • Pressure cooking is highly effective at reducing lectins
  • Peeling and deseeding reduces lectin content
  • Fermentation can reduce lectins in some foods
  • Sprouting may increase or decrease lectins depending on the food

What to know about acorn nuts

Acorns are one of the very few foods you cannot simply eat off the tree. Raw acorn is loaded with bitter tannins, which is why every traditional acorn food (Korean dotorimuk jelly, dotori guksu noodles, Native American acorn flour) begins by leaching those tannins out in water. Once leached, the trigger profile becomes a straightforward nut profile: acorns are high in nickel and high in lectins, borderline on salicylates, oxalate and FODMAPs, and only mildly anti-inflammatory despite the antioxidant reputation oak nuts have picked up online.

Watch for

  • Unleached acorn is the real hazard, and it is chemistry rather than allergy.The tannins are astringent enough to irritate the gut lining and commonly cause nausea and stomach cramping, so anything you eat should have been leached or bought as processed acorn starch
  • High in nickel.Nuts and seeds are among the largest dietary nickel contributors, and milling acorns into flour concentrates the kernel, so acorn noodles are a bigger nickel load than the portion size suggests
  • High in lectins, which is worth knowing if under-processed nut flours are already a pattern for you.Cooking and the leaching step both help, but the raw kernel is the worst version
  • Moderate for FODMAPs and for SIBO, so a full bowl of acorn noodles behaves differently from a small side of acorn jelly.Log the portion, not just the food
  • Borderline on both salicylates and oxalate.Neither is high enough to lead with, but if either is already one of your patterns, acorn belongs on the watch list rather than the safe list
