Diet Ratings

Keto8/10APPROVED

Sucralose is a non-nutritive artificial sweetener with zero net carbs and no caloric content. It does not trigger insulin response or affect blood glucose. Widely used in keto diet. Some formulations contain maltodextrin filler which adds carbs; pure sucralose is keto-safe.

Vegan6/10CAUTION

Sucralose is a synthetic sweetener with no animal ingredients, making it technically vegan. However, it is heavily processed and some vegans avoid it due to environmental concerns and potential health considerations. Not a whole food.

Paleo2/10AVOID

Sucralose is a synthetic chlorinated sugar derivative created in a laboratory. It is not a food available to Paleolithic humans and represents processed food technology. While regulatory agencies deem it safe, paleo philosophy excludes artificial additives and processed foods.

Mediterranean2/10AVOID

Sucralose is a synthetic artificial sweetener with no nutritional value. It contradicts Mediterranean diet principles emphasizing whole, minimally processed foods. While generally recognized as safe, it represents the antithesis of traditional Mediterranean eating patterns focused on natural foods.

Carnivore5/10CAUTION

Sucralose is a synthetic sweetener derived from sucrose through chlorination. It is not animal-derived but is chemically processed and non-caloric. Many carnivores use it, but strict practitioners avoid all sweeteners.

iLion Diet adherents and strict carnivores like those following Saladino's stricter protocols avoid all sweeteners. Baker acknowledges some practitioners use sucralose but recommends caution due to potential metabolic effects and sweetener dependency.

Whole301/10AVOID

Sucralose is a synthetic artificial sweetener. Whole30 explicitly excludes artificial sweeteners and sugar substitutes.

Low-FODMAP9/10APPROVED

Sucralose is a non-nutritive artificial sweetener with zero FODMAP content. Not fermented by gut bacteria. Monash University confirms it is low-FODMAP at all practical serving sizes.

DASH5/10CAUTION

Sucralose is non-caloric and non-glycemic, approved by FDA. DASH guidelines don't prohibit it as it avoids added sugar. However, emerging evidence suggests potential effects on gut microbiota and glucose metabolism; some clinicians recommend moderation.

iNIH DASH guidelines treat approved artificial sweeteners neutrally; updated clinical interpretation increasingly questions long-term metabolic effects and recommends water/unsweetened beverages as primary choice.

Zone5/10CAUTION

Non-caloric sweetener with zero glycemic impact. Dr. Sears generally permits artificial sweeteners in Zone protocol. However, emerging research on gut microbiome effects creates debate. Acceptable for Zone macros but not ideal for anti-inflammatory philosophy.

iSome Zone practitioners and newer research suggest non-nutritive sweeteners may impair glucose regulation and gut health, conflicting with Zone's anti-inflammatory intent despite macro neutrality.

Artificial sweetener with mixed evidence. Generally recognized as safe by FDA, but emerging research suggests potential effects on gut microbiome and glucose metabolism. Some anti-inflammatory experts prefer natural sweeteners. Acceptable in moderation but not ideal.

iDr. Weil and some functional medicine practitioners prefer stevia or monk fruit over synthetic sweeteners due to microbiome concerns, though mainstream consensus considers sucralose safe in typical amounts.

GLP-1 Friendly8/10APPROVED

Non-caloric artificial sweetener with no blood sugar impact. Widely recommended for GLP-1 patients to satisfy sweet cravings without triggering nausea or metabolic disruption. No digestive side effects at typical use levels. Supports adherence to low-sugar diet.
