Across 1,081 single-item logs where 636 Signos members ate a date alone, the average glucose peak was +35.2 mg/dL — moderate-to-high territory for a dried fruit carrying concentrated sugar. Stuff a Medjool with almond butter and the peak drops to +32.5 mg/dL; chop one into overnight oats and it climbs to +43.4 mg/dL. The fork in the road is what you put with it.

Yes — across 1,081 single-item logs where members ate a date alone, the average glucose peak was +35.2 mg/dL, with 53.2% of responses exceeding the +30 mg/dL threshold. Across our single-item cohort of 1,081 date logs from 636 unique members, the mean glucose peak was +35.2 mg/dL — moderate-to-high territory and one of the higher means in the fruit category. Dates are dried fruit, and concentrated sugar is the core driver: a single Medjool carries ~16g of fast-digest fructose and glucose. The conventional GI of 29 understates the real-world response because the 25g reference serving doesn't match how members typically eat them. Three levers shape the variance: total meal carb load (the single biggest factor, at +36% when the meal hits ≥60g carbs), what you stuff or pair the date with (almond/peanut butter trims −4 mg/dL across 1,498 logs), and form (Medjool anchors highest at +37.8 mg/dL; date syrup lowest at +31.4 mg/dL). The IQR spans 26 mg/dL (p25: +21, p75: +47).
Some members spike +31.7 mg/dL. Others spike +45. The only way to know how you'll spike is to measure with a Signos CGM.
Dates produce a mean peak of +35.2 mg/dL across 1,081 single-item meals where members ate one alone — moderate-to-high territory among fruit pages, reflecting that dates are dried, sugar-concentrated rather than fresh. The IQR spans 26 mg/dL (p25: +21, p75: +47), showing wide individual variability. Three levers explain most of that range in the broader 7,742-meal cohort. First, total meal carb load dominates: meals with ≥60g of carbs spike 36% higher than the low-carb baseline (n=2,199, p<0.001), and very heavy meals (110g+ carbs) average +45.0 mg/dL — a 42% escalation. Second, the stuffed-date pairings cut measurably: almond/peanut butter drops the peak −4 mg/dL across 1,498 matched logs. Third, the overnight-oats pairing adds +7 mg/dL on 258 logs by stacking carb loads. These effects are observational from matched-pair Welch's t-tests, not controlled trials.
This page is grounded in 7,742 logged meals containing dates from 2,168 unique Signos members, captured through the Signos production PPGR cohort. The page-primary cohort is the single-item cut: 1,081 meals where a date was logged alone, from 636 unique members, with a mean peak of +35.2 mg/dL, median +32 mg/dL, and IQR p25 +21 / p75 +47 mg/dL. Data was filtered to meals with a measured glucose rise between 0 and 100 mg/dL (ppgr_case='regular') to exclude outliers and sensor artifacts. Statistical comparisons between modifier groups use Welch's t-test on matched pairs; all effects reported at p<0.05 minimum, with the dominant modifiers reaching p<0.001. Date logs were identified via a regex cohort match on "date" / "dates" with an aggressive exclusion list to filter out non-fruit uses (date night, due date, expiration date, date of birth, etc.). Date forms (Medjool, Deglet Noor, date syrup/molasses) and pairing categories (stuffed with nut butter, stuffed with goat cheese/bacon, in vegan baking, chopped into overnight oats) are identified by sub-form regex matching. A minimum of 100 matched meals was required for any modifier to appear in the recipe builder; smaller sub-cohorts are flagged at medium confidence in the calculator.
