Why nightshades food checker matters

Nightshades are a plant family including tomatoes, peppers, eggplants, and potatoes. Some people find that avoiding nightshades helps with joint pain, digestive issues, or inflammatory conditions, though research is limited.

What to know about acesulfame potassium

Acesulfame potassium, listed as Ace-K or E950, is an intense sweetener roughly two hundred times sweeter than sugar that your body does not metabolise at all: it is absorbed, passed through unchanged and excreted in urine, so it delivers no calories and no blood sugar response. On the sensitivity columns it comes back A across the board, including gluten, lactose, dairy protein, histamine, salicylate, oxalate, nickel, sulfite and glutamate, and every FODMAP group including polyols is clean, so it does not behave like the sugar alcohols it often sits beside. The catch is that you almost never meet it alone. On its own it carries a bitter, slightly metallic finish, so manufacturers blend it with sucralose or aspartame to mask that, which means a reaction blamed on Ace-K is frequently a reaction to the blend. It is also graded E for low-fermentation and SIBO protocols and E for DASH, which are plan-fit calls about ultra-processed sweeteners rather than chemical trigger findings.

Watch for

It is a blending sweetener, not a solo one.Check the full sweetener line on the label before attributing anything to Ace-K, because sucralose or aspartame is nearly always in there with it
Graded E for low-fermentation and SIBO plans and E for DASH, so it is one to leave out if you are running a strict protocol of either kind, even though the chemical trigger columns are clean
It is not a sugar alcohol.Sorbitol, maltitol and xylitol pull water into the bowel and ferment, which is why they cause gas and loose stools. Ace-K has no polyol content and grades A for polyols, so that particular mechanism does not apply to it
Heat stable, unlike aspartame, so it survives baking and turns up well beyond soft drinks: protein powders, yogurts, chewing gum, sauces, flavoured waters, medicines and toothpaste.Your total exposure is usually wider than you think
The potassium in the name is just the counter-ion that makes the salt.The quantity used to sweeten a drink is measured in tens of milligrams, so it is not a meaningful source of dietary potassium
