What to know about sucralose

Sucralose is made by replacing three hydroxyl groups on ordinary sugar with chlorine atoms, which makes it roughly 600 times sweeter than sucrose and largely indigestible. Most of a dose passes straight through the gut, and that is why it grades clean on the classic food-chemistry triggers: no gluten, no lactose or dairy protein, no histamine, no tyramine, no sulfites, no nightshade content, and unlike the sugar alcohols it is not a polyol. Two things catch people out. Sucralose is not stable at baking temperatures, which is why some products carry a quiet warning against cooking with them. And the granulated sucralose sold in packets and bags, Splenda included, is mostly maltodextrin or dextrose by weight, which is where the calories and the blood sugar response come from. It also rates poorly on low-fermentation and SIBO protocols and sits well outside DASH and Mediterranean eating patterns.

Watch for

Heat sensitive.Sucralose begins to degrade above roughly 120C and can form chlorinated breakdown products, and German risk assessors have advised against heating foods sweetened with it to frying or baking temperatures. That is the reason some tabletop products say they are not intended for baking.
Packet and granulated versions are mostly bulking agent.Maltodextrin or dextrose makes up the volume, carries the calories the label rounds down to zero, and maltodextrin has a higher glycaemic index than table sugar, so heavy users can see a genuine blood sugar bump from a supposedly zero-calorie sweetener.
Rated poorly for low-fermentation and SIBO plans, which routinely exclude non-nutritive sweeteners.If bloating started when you switched to sucralose, the bulking agent deserves as much suspicion as the sweetener itself.
Rated pro-inflammatory and a poor fit for DASH and Mediterranean patterns, both of which push you toward reducing sweetness rather than swapping one intense sweetener for another.
Clean on gluten, dairy, histamine, tyramine and sulfites, so when a diet drink reliably bothers you it is worth reading past the sweetener to the acids, colours and preservatives in the same can.
