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 yeast extract

Yeast extract is yeast that has been made to digest itself. Saccharomyces cerevisiae cells are autolysed so the cell walls break and the contents spill out, and what spills out is a concentrate of free amino acids, including a great deal of free glutamic acid, plus the nucleotides that multiply savoury flavour. That is the entire point of the ingredient and it is also its trigger story: free glutamate is graded E, the single highest mark on the page, and the only E in the whole grade set. This is where yeast extract separates hard from nutritional yeast flakes, which come in at A on the same criterion. Flakes are dried whole yeast. Extract is the inside of the yeast, concentrated, and it behaves like a glutamate ingredient because chemically that is what it is. It is why food manufacturers reach for it when they want savoury depth without printing monosodium glutamate on the panel. The second grade worth knowing is gluten at C, which surprises people who think of it as a vegan pantry staple: a lot of yeast extract is made from spent brewer yeast left over from beer, and barley malt extract is a common companion ingredient. The rest reads calmer than the reputation suggests. FODMAPs are graded A, histamine and tyramine both B, sulfite A, lactose A, nickel A, fermentability for SIBO B. If you react to yeast extract, glutamate sensitivity is the first hypothesis to test, not the last.

Watch for

Free glutamate graded E, the highest grade on this page.If added MSG is a known trigger for you, yeast extract is the same molecule arriving under a friendlier name, and it carries no E number because it is treated as an ingredient rather than an additive
Gluten graded C.Yeast extract is frequently produced from brewer yeast recovered from barley beer, and barley malt extract often rides along in the recipe. Dedicated gluten free versions exist as separate products, so the category grade is a prompt to read the specific jar rather than a verdict on all of them
It is mostly hiding rather than spread on toast.Stock cubes, gravy granules, instant soup, crisp seasonings, veggie burgers, savoury biscuits and plant based ready meals all use it, so a glutamate reaction can look random until you start reading the small print on savoury packets
Salt is a huge fraction of it by weight, which is a real consideration if you are working to a sodium target, even though the amount actually eaten in one scrape is small
Tyramine and histamine are graded B here, moderate, which is lower than its reputation.Yeast extract still appears by name on MAOI diet sheets and on migraine handouts, so if you have been given one of those lists, follow the list rather than the grade and treat this as a caution flag rather than a clearance
