Across 29,187 caramel-tagged logs from 7,421 members, the average glucose peak was +29.2 mg/dL — caramel is cooked sucrose with a real GI of 40 and a glycemic load of 13 per 30g serving. The form anchors say it cleanly: syrup or sauce drizzle anchors at +29 mg/dL (n=10,890), candy or chew climbs to +44 (n=258), and salted caramel is a flavor variant, not a glucose-different one (+28, n=4,076). Caramel corn is the cohort outlier — +47 mg/dL across 1,049 logs, a +19 delta over the alone baseline.

Yes — caramel is cooked sucrose with a published GI of 40 and a glycemic load of 13. The +29.2 mg/dL cohort average across 29,187 logs reflects real sugar, real curve. Caramel is sucrose heated until it browns through caramelization — the chemistry changes the color and flavor, not the digestibility. Across 29,187 logged caramel meals from 7,421 Signos members, the cohort mean was +29.2 mg/dL with a median of +25 and an IQR spanning 25 mg/dL (p25: +13, p75: +38). The form structure tells the story cleanly: syrup or sauce drizzle anchors at +29 mg/dL (n=10,890), salted caramel reads functionally identical at +28 (n=4,076) — the salt is flavor only — and candy or chew climbs to +44 (n=258), the highest form. The vehicle drives wider variance: caramel corn is the outlier at +47 mg/dL (+19 delta, n=1,049), custard and crème brûlée came in at +43 (+15, n=267), caramel apple at +37 (+9, n=634), and latte and sundae each at +32–33 (+4 to +5). Two buffers help: pairing with nuts trimmed the peak −5 mg/dL across 9,210 logs (high confidence), and pairing with coffee dropped it −5 mg/dL across 6,291 logs. Caramel isn't an empty-calorie afterthought — it's a real sweetener with measurable shape.
Some members spike +25.7 mg/dL. Others spike +49. The only way to know how you'll spike is to measure with a Signos CGM.
Caramel produces a cohort-mean peak of +29.2 mg/dL across 29,187 logs from 7,421 members — a moderate response that tracks closely with caramel's published glycemic index of 40 and glycemic load of 13 per 30g serving. Caramel is sucrose heated until it browns through caramelization reactions — the chemistry changes the color and flavor but not the digestibility, so the body breaks it back down into glucose and fructose within 30 minutes. Three levers explain most of the cohort variance. First, the form: syrup/sauce drizzle anchors at +29 mg/dL (n=10,890), salted caramel reads functionally identical (+28, n=4,076), and candy/chew climbs to +44 (n=258) — likely because the dose per piece is larger and the slow-melt prolongs the sucrose entry. Second, the vehicle: caramel corn is the outlier at +47 mg/dL (+19 delta over alone, n=1,049), with custard, caramel apple, latte, and sundae filling in between. Third, the buffer: pairing with nuts or coffee each trimmed the peak by 5 mg/dL across thousands of matched logs (p<0.001). Effects are observational from matched-pair Welch's t-tests, not controlled trials.
This page draws on 29,187 caramel-tagged logged meals from 7,421 unique Signos members, captured through the Signos production CGM platform between Mar 2025 and Apr 2026. Data were filtered to postprandial glucose responses (PPGR) between 0 and 100 mg/dL to exclude sensor artifacts. Modifier effects were estimated using Welch's t-test on matched pairs against a defined baseline; reported effects carry p<0.05 minimum, with the dominant modifiers reaching p<0.001. Because caramel has a published glycemic index of 40 and glycemic load of 13 per 30g serving, the recipe-builder form anchors reflect the cohort-derived non-zero values — syrup/sauce at +29 mg/dL, candy/chew at +44, salted caramel at +28. Caramel logs were identified by a regex matching the bare term "caramel", with explicit exclusions for cooking-technique uses (caramelized onion, garlic, shallot, leek, fennel, sugar) and the food-coloring additive caramel color (common in colas). A minimum of 100 matched meals was required for any food pairing to appear in the recipe builder.
