Buffalo sauce: the heat is famous, the salt is the number

Buffalo sauce borrows its reputation from chili peppers, and the pepper compound capsaicin has been tested properly. Across 15 randomized trials in 762 adults with overweight or obesity, capsaicin supplements, at doses a sauce cannot supply, cut body weight by 1.1 lb (95% CI 0.33 to 1.9; metric: 0.51 kg, 0.15 to 0.86) and waist by 0.44 in (1.12 cm). That is a real effect and a small one. Across 14 trials the same supplements did not change fasting glucose, with a pooled difference of 0.54 mg/dL (95% CI -0.9 to 2.2; metric: 0.03 mmol/L, -0.05 to 0.12). What the sauce itself reliably delivers is sodium. A single US dietary survey record puts 100 g at 2917 mg sodium and only 11 calories, and one 16 g tablespoon at about 467 mg, roughly a fifth of the 2300 mg Daily Value. A 28 g dipping cup brings about 817 mg. The 11 calories figure fits a recipe made without butter, and we have no record for a homemade sauce made with it.

As people eat it, per 3.5 oz (100 g)

How much is actually in it

• In US survey data buffalo sauce is mostly a salt carrier: 2917 mg sodium but only 11 calories per 3.5 oz (100 g). — Buffalo sauce as coded in the US dietary survey, 100 g Evidence E source
  Sodium 2917 mg, energy 11 calories per 3.5 oz (100 g)

What a real portion looks like

• One tablespoon of buffalo sauce (16 g) carries about 467 mg sodium and a dipping cup (28 g) about 817 mg, roughly a fifth and a third of the 2300 mg Daily Value. — US portion measures for buffalo sauce Evidence E source
  1 tablespoon 16 g = 466.7 mg sodium, dipping-size container 28 g = 816.8 mg

What it does to your health

• Observational data link eating chili pepper, ever or more than once a week, with 13% lower all-cause mortality across four cohorts of 564,748 people. — Adults in 4 prospective cohort studies (n = 564748) Evidence C source
  All-cause mortality HR 0.87 (95% CI 0.85-0.90), CVD mortality HR 0.89 (0.85-0.93)

Safety, limits and interactions

• Observational data link high chili consumption with about 2.3 times higher odds of gastric cancer, while moderate intake showed no clear link. — 3,095 gastric cancer cases and 4,761 controls in 13 studies (n = 13 studies) Evidence C source
  High intake OR 2.28 (95% CI 1.76-2.96), moderate intake OR 0.72 (0.36-1.41)

What people believe that the data does not support

• Capsaicin supplements, the heat compound in buffalo sauce peppers, trimmed only 1.1 lb (0.5 kg) of body weight and 0.43 in (1.1 cm) of waist across 15 trials in people with overweight. — Adults with overweight or obesity, capsaicin supplementation (n = 15 RCTs, 762 people) Evidence A source
  Body weight WMD -1.1 lb (95% CI -1.9 to -0.33; metric: -0.51 kg, -0.86 to -0.15), waist -0.44 in (95% CI -0.79 to -0.09; metric: -1.12 cm, -2.00 to -0.24), BMI -0.25
• Across 14 trials capsaicin did not change fasting blood glucose, with a pooled difference of 0.54 mg/dL (0.03 mmol/L). — Adults in controlled trials of capsaicin supplementation (n = 14 trials) Evidence A source
  Fasting glucose WMD 0.54 mg/dL (95% CI -0.9 to 2.2; metric: 0.03 mmol/L, -0.05 to 0.12), no effect on insulin
• Red pepper or capsaicin did not lower blood pressure in pooled clinical trials, with systolic pressure changing by 0.43 mmHg. — Adults in clinical trials of red pepper or capsaicin Evidence A source
  SBP +0.43 mmHg (95% CI -1.15 to 2.01), DBP -0.45 mmHg (95% CI -2.14 to 1.24)
• Culinary doses of red pepper did not significantly raise energy expenditure in a synthesis of 24 randomized studies, though they did shift the body toward burning more fat. — Adults in randomized studies of culinary red pepper doses (n = 24 studies) Evidence A source
  Energy expenditure change not significant, respiratory quotient consistently lower

What is still unknown

• A 2026 review of 13 trials in 821 adults rated evidence that red pepper improves blood lipids or glucose as low to very low, and found no effect on LDL cholesterol. — Adults in RCTs of capsaicin, red pepper or related compounds vs placebo (n = 13 RCTs, 821 people) Evidence A source
  No significant effect on TG, LDL, HDL, SBP, glucose, insulin, HbA1c, small unstable TC and DBP reductions

The bottom line

Hot sauce as a metabolism booster was tested, and at kitchen doses the effect did not reach significance. A synthesis of 24 randomized studies of culinary red pepper doses found no significant long-term rise in energy expenditure. The body did burn a slightly higher share of fat, and the abstract gives no size for that shift. Pooled trials of red pepper or capsaicin found no effect on blood pressure, with systolic pressure moving 0.43 mmHg (95% CI -1.15 to 2.01), in an analysis with high heterogeneity whose abstract does not say how many trials went in. A 2026 review of 13 trials in 821 adults found no effect on LDL cholesterol, triglycerides, glucose or HbA1c, and rated the evidence low to very low. Observational data from four cohorts of 564,748 people link eating chili pepper, ever or more than once a week, with 13% lower all-cause mortality (HR 0.87, 95% CI 0.85 to 0.90). The exposure was chili in general, the cohorts did not look at buffalo sauce, and people who eat chili may differ in ways the adjustment could not catch. The caution on this page is about salt and about a lot of chili. Across 13 mostly case-control studies with 3,095 gastric cancer cases, high chili consumption went with 2.28 times the odds of gastric cancer (95% CI 1.76 to 2.96), while moderate intake showed no clear link (OR 0.72, 95% CI 0.36 to 1.41). These are odds from studies of high chili intake, and none of them measured sauce. If you have been told to limit sodium, a tablespoon of buffalo sauce counts as about 467 mg. We have no cards on pregnancy, children, kidney disease or interactions with medicines for this sauce, so this page says nothing about them.
