Mixed Nuts Glycemic Index and Calculate Your Own Glucose Response

Across 5,660 logs of mixed nuts eaten alone, the average glucose peak was +21.4 mg/dL with a median of just +17 mg/dL — the lowest snack in our atlas. Pair them with apple (+4 mg/dL) or dark chocolate (+3 mg/dL) and the build still lands under +30 mg/dL; the fat and fiber are doing serious work.

● Key Findings · Do mixed nuts spike blood sugar?

Barely — averaging just +21.4 mg/dL across 5,660 single-item logs, with 59.4% of responses falling in the low-spike band. The lowest snack in our atlas. Across 5,660 logs of mixed nuts eaten alone, the average glucose peak was +21.4 mg/dL (median +17 mg/dL) — lower than any other snack we've measured in the cohort, including chocolate (+29.0 mg/dL), apple (+31.5 mg/dL), and chips (+38.9 mg/dL). That tracks with the published GI of 24 and GL of 3. The fat and fiber are doing serious work: even pairing the nuts with crackers (+7 mg/dL above baseline) or apple (+4 mg/dL) keeps the total build under +35 mg/dL. The only lever that meaningfully moves the curve is the surrounding meal — a 110g+ carb meal pushes peaks to +40.1 mg/dL, but that's still gentler than chips eaten alone.

  • ▸Mixed nuts ranked lowest of every snack we measured: chocolate (+29.0), apple (+31.5), ice cream (+35.8), popcorn (+37.2), chips (+38.9 mg/dL) all tracked higher in matched cohort rankings.
  • ▸Carb pairings barely move the curve: apple added +4 mg/dL (n=1,129), dark chocolate added +3 mg/dL (n=637), and even crackers — the largest measured penalty — added just +7 mg/dL (n=389).
  • ▸Form barely matters: salted, unsalted, roasted, and raw mixed nuts all landed within ±0.9 mg/dL of the +24.8 mg/dL whole-cohort default.
  • ▸The carb-load effect is the only meaningful lever: meals with 110g+ total carbs averaged +40.1 mg/dL — a 74% escalation over the +23.0 mg/dL light-carb baseline (n=204 vs. n=17,617).
● Signos Rules

Three citable insights from this recipe's data

Rule 1
"The Fat-and-Fiber Buffer"
+4 mg/dL with apple
Apple paired with mixed nuts averaged +28.8 mg/dL (n=1,129) — only +4 mg/dL above the +24.6 mg/dL alone-baseline, and meaningfully lower than the +31.5 mg/dL apple-alone cohort average. Dark chocolate adds even less (+3 mg/dL, n=637). The mechanism: fat and fiber slow gastric emptying, blunting whatever fast-digest carb arrives alongside. Crackers are the only pairing that adds more than 5 mg/dL — and they still cap the build at +31.8 mg/dL.
Rule 2
"The Carb-Load Penalty"
+74% peak
When mixed nuts appear in a meal with 110g+ of total carbs, the glucose peak climbs to +40.1 mg/dL — 74% above the +23.0 mg/dL light-carb baseline (n=204 vs. n=17,617). Mixed nuts themselves average just 8g of carbs in single-item logs; every extra mg/dL above that baseline comes from the bread, rice, pasta, or sweets on the plate alongside them. The high_carb modifier confirmed it directly — meals with ≥60g carbs ran 57.6% higher than the low-carb baseline (n=1,685, p<0.001).
Rule 3
"The Snack-Time Edge"
−5 mg/dL vs. dinner
Mixed nuts logged as a snack averaged +22.7 mg/dL (n=8,041) — the lowest meal-time slot in the cohort and 5 mg/dL below dinner-time logs at +27.7 mg/dL (n=3,441). Breakfast tracked at +25.8 mg/dL and lunch at +26.1 mg/dL. The pattern is consistent with snack contexts having lighter carb co-loads than full meals — and the form variation (salted, roasted, raw) doesn't move the curve, so the meal-time gap reflects what's eaten alongside, not the nuts.
● Curious about your own?

Curious how your body responds to mixed nuts specifically?

Across 5,660 single-item mixed-nut logs, the average glucose peak was +21.4 mg/dL — but the IQR spans 20 mg/dL (p25: +9, p75: +29), meaning individual responses vary widely. Your own result depends on the surrounding meal, baseline glucose, and metabolic state. A CGM tells you which side of that range you actually land on.

Learn how Signos works
Why this meal spikes

This meal stacks 3 independent spike drivers — together they account for +25 mg/dL.

Driver 1
Meal-level carbohydrates (~60g+ when paired)
+13 mg/dL
The dominant lever: meals with ≥60g carbs ran 57.6% higher than the low-carb baseline (CI: +12.3 to +14.2 mg/dL, n=1,685 vs n=17,617, p<0.001). Mixed nuts themselves average just 8g of carbs in single-item logs — the rest comes from the bread, rice, or sweets they're eaten with.
Driver 2
Sugar load in the meal (≥20g sugars)
+11 mg/dL
High-sugar pairings raised peaks 47.2% over the low-sugar baseline (CI: +9.9 to +11.6 mg/dL, n=2,301 vs n=15,694, p<0.001). The crackers pairing (+7 mg/dL) and the apple pairing (+4 mg/dL) both contribute to this lever.
Driver 3
Individual glucose variability (IQR 20 mg/dL)
+5 mg/dL
The interquartile range spans 20 mg/dL (p25: +9, p75: +29 mg/dL in single-item logs), meaning personal metabolic state — insulin sensitivity, recent activity, baseline glucose — accounts for a substantial portion of any given reading.

● What surprised us
What surprised us about mixed nuts is how stubbornly the curve refuses to move. Across 5,660 single-item logs, mixed nuts averaged just +21.4 mg/dL — the lowest snack in the atlas, gentler than chocolate (+29.0), apple (+31.5), or chips (+38.9). Even pairing them with crackers or apple barely moves the dial: +7 and +4 mg/dL respectively, both keeping the total build under +35. The fat and fiber are doing real work — most foods we measure react sharply to carb pairings, and mixed nuts simply don't.
— Signos Data Science Team

Why this happens, physiologically

Mixed nuts are a low-carb, high-fat, high-fiber food — a 1-oz serving carries roughly 5–8g of total carbs and 3g of fiber — so the modest single-item peak of +21.4 mg/dL across 5,660 logs reflects the carb context of the surrounding meal far more than the nuts themselves. The largest lever measured is total meal carb load: meals with ≥60g of carbs ran 57.6% higher than the low-carb baseline (CI: +12.3 to +14.2 mg/dL, p<0.001), and the carb-bucket analysis shows a near-linear escalation from +23.0 mg/dL in light (0–40g) meals to +40.1 mg/dL in very-heavy (110g+) meals — a 74% jump. Two secondary levers pull the same direction: high-sugar pairings (≥20g) raised the response 47.2%, and high-fiber pairings tracked 23.8% higher (correlational — high-fiber co-meals also tend to include cereals or granolas that drive the peak independently). The pattern is observational, not yet causal, but consistent with fast-digesting starch and sugar driving the spike while the nuts' own fat and fiber attenuate it.

● Three mechanisms explain the mixed-nut glucose range

Carb co-load, sugar pairing, and fat content together explain why mixed nuts produce the smallest cohort spike of any snack we measured

  1. Mechanism 1
    +57.6%
    High carb co-load
    Meals logged with ≥60g total carbs showed peaks 57.6% above the low-carb baseline (CI: +12.3 to +14.2 mg/dL, n=1,685 vs n=17,617, p<0.001). Mixed nuts add only ~5–8g of carbs per ounce — every point of that escalation comes from the bread, rice, or sweets they're eaten with.
  2. Mechanism 2
    +47.2%
    High-sugar pairing
    Pairings with ≥20g of sugars raised the response 47.2% above the low-sugar baseline (CI: +9.9 to +11.6 mg/dL, n=2,301, p<0.001). The crackers pairing (+7 mg/dL) and the apple pairing (+4 mg/dL) both sit on this lever — though both stay well below where the same foods land alone.
  3. Mechanism 3
    −0.6%
    Fat in the meal
    High-fat pairings (≥15g) tracked −0.6% lower than the low-fat baseline (CI: −2.4 to +2.0 mg/dL, n=18,846 vs n=252, p=0.89). The effect is statistically flat — nearly every mixed-nut log already carries ≥15g of fat from the nuts themselves, so adding more produces no incremental change.
● Fit Check
Mixed nuts are the lowest-spike snack in the atlas — the only meaningful lever is the surrounding carb load, and even that stays gentler than what we measure for most other snacks alone.
✓ This is for you if
  • ▸You eat mixed nuts as a standalone snack. Snack-time logs averaged just +22.7 mg/dL across 8,041 entries — the lowest meal-time slot in the cohort, with 59.4% of single-item responses landing in the low-spike band.
  • ▸You pair mixed nuts with apple or dark chocolate. Apple added just +4 mg/dL (n=1,129) and dark chocolate added +3 mg/dL (n=637) — both keep the total build under +30 mg/dL.
  • ▸You're indifferent to salted vs. unsalted vs. roasted. All four form variants landed within ±0.9 mg/dL of the +24.8 mg/dL default, so pick whichever you like.
  • ▸You keep total meal carbs under 40g. Light-carb mixed-nut meals averaged +23.0 mg/dL across 17,617 logs — the lowest carb-bucket slot in the cohort.
✗ Not for you if
  • ▸You combine mixed nuts with a 110g+ carb meal. That bucket averaged +40.1 mg/dL — 74% above the +23.0 mg/dL light-carb baseline (n=204 vs n=17,617).
  • ▸You add mixed nuts to crackers as a regular snack. The crackers pairing averaged +31.8 mg/dL — a +7 mg/dL bump over the alone-baseline (n=389), the largest pairing penalty measured.
  • ▸You're chasing a guaranteed flat curve. The IQR in single-item logs spans 20 mg/dL (p25: +9, p75: +29) — the food is low-spike on average, but personal variability is real.
  • ▸You use mixed nuts as the dessert tail of a heavy dinner. Dinner-time logs averaged +27.7 mg/dL (n=3,441) — 5 mg/dL above snack-time, reflecting the heavier carb co-load at that meal slot.

Calorie band and pairings (member-measured)

Per serving
165–1,340 kcal
Ranges from a 1-oz handful (~165 kcal, single-item average 216 kcal) to a full mixed-nut-containing very-heavy-carb meal (~1,340 kcal).
● Pair before
  • ▸Pair mixed nuts with apple or dark chocolate when you want a fuller snack: both pairings stayed within +4 mg/dL of the alone-baseline across 1,766 combined logs.
  • ▸Keep total meal carbs under 40g when mixed nuts ride along with a meal: the light-carb bucket averaged +23.0 mg/dL vs. +40.1 mg/dL in the 110g+ bucket — a 74% escalation across 17,617 vs. 204 logs.
● Pair after
  • ▸If mixed nuts ride along with a 70g+ carb meal, time a 15–20 min walk: the heavy-carb (70–110g) and very-heavy (110g+) buckets averaged +35.6 and +40.1 mg/dL respectively.
  • ▸Note that snack-time logs ran +22.7 mg/dL vs. dinner at +27.7 mg/dL — a 5 mg/dL gap that favors snacking over meal-tailing.
● Avoid pairing
  • ▸Avoid mixed nuts as the snack of a sweets-heavy build: the high-sugar modifier (≥20g) ran +47.2% above baseline (CI: +9.9 to +11.6 mg/dL, n=2,301).
  • ▸Avoid using mixed nuts as a casual top-up on a 110g+ carb meal — that bucket averaged +40.1 mg/dL, the only carb-bucket slot above +35 mg/dL.

Frequently Asked Questions

Methodology

This page draws on 21,641 logged meals containing mixed nuts from 4,332 unique Signos members, with a 5,660-meal single-item subset (mixed nuts logged alone, no pairings) collected through the Signos production CGM platform. Data were filtered to postprandial glucose responses (PPGR) between 0 and 100 mg/dL to exclude sensor artifacts and implausible readings. Modifier effects were estimated using Welch's t-test on matched pairs against a defined baseline; all reported effects carry p<0.001 unless noted. We report mean glucose peak across a right-skewed distribution — the median single-item spike of +17 mg/dL is several mg/dL lower than the mean of +21.4 mg/dL, which is typical for this type of data. The food was identified using a regex matching "mixed nut(s)" as a primary ingredient, with explicit excludes for trail mix (which typically includes dried fruit and chocolate). Any carb-pair pairing slot requires at least 100 matched meals before it appears in the recipe builder.

Limitations

  • Self-reported portion sizes introduce measurement error — a logged "1 oz" of mixed nuts may vary in actual weight, affecting per-serving spike estimates.
  • Cohort skews health-motivated; Signos members actively tracking glucose tend to eat more mindfully than the general population, so real-world average spikes may differ.
  • The crackers-pairing sub-cohort (n=389) carries medium confidence — the +7 mg/dL delta is directional, with the upper bound less certain than the apple or dark-chocolate pairings.
  • The high-fat modifier (−0.6%, p=0.89) is not statistically distinguishable from zero — the baseline cohort for that test is small (n=252) because nearly every mixed-nut log already carries ≥15g of fat from the nuts themselves.
  • Modifier analyses reflect meal-level correlations, not controlled feeding trials — causality cannot be established from observational CGM data alone.
  • The high-fiber modifier (+23.8%) is correlational; high-fiber mixed-nut meals also tend to include cereals, oats, or granolas that drive the peak independently of the fiber itself.

See your own mixed-nut response

Across 5,660 single-item mixed-nut logs, the average glucose peak was +21.4 mg/dL — the lowest snack in the atlas. But the IQR spans 20 mg/dL (p25: +9, p75: +29), meaning your personal response could land well above or below that. Pairings barely move the curve — apple +4, dark chocolate +3, crackers +7 — but the surrounding carb load can. A CGM shows you exactly where you land and which builds work best for your biology.
