Beef jerky: a protein snack that is mostly a sodium question

Sodium is the number to watch in beef jerky, and it is the one with firm evidence behind it. A meta-analysis of 35 randomized trials in 2,885 people already treated for high blood pressure found that every 100 mmol less sodium a day lowered systolic pressure by 6.81 mm Hg (95% CI 4.96 to 8.66). Those 100 mmol equal 2.3 g of sodium, about what 4.6 oz (130 g) of jerky holds. The US survey database gives beef jerky 1,785 mg sodium and 33.2 g protein per 3.5 oz (100 g), so its default 1.1 oz (30 g) serving carries about 536 mg sodium and 10 g protein. That is one figure with no spread, and brands differ widely. A single meat stick is coded at 7 to 18 g and a cup of pieces at 90 g.

How much is actually in it

• The US dietary survey database puts beef jerky at 1,785 mg sodium and 33.2 g protein per 3.5 oz (100 g), so a default 1.1 oz (30 g) serving carries about 536 mg sodium and 10 g protein. — FNDDS food code 21602100 Beef jerky (n = 1 food code) Evidence E source
  Sodium 1785 mg and protein 33.2 g per 3.5 oz (100 g); 1.1 oz (30 g) serving 535.5 mg sodium, 10.0 g protein

What a real portion looks like

• US survey coding weighs a single meat stick at 7 to 18 g, a Slim Jim at 10 g and a cup of jerky pieces at 90 g. — FNDDS food code 21602100 Beef jerky (n = 7 portion measures) Evidence E source
  1 Big Jerk 7 g, 1 Super Jerk 10 g, 1 Giant Jerk 18 g, 1 Slim Jim 10 g, 1 cubic inch 12 g, 1 cup pieces 90 g, quantity not specified 30 g

What it does to your health

• In a randomized counterbalanced trial in 8 trained runners over three weeks, beef jerky after exercise did not change hydration, body mass or blood pressure compared with a standard recovery drink. — Trained male endurance runners aged about 22, three identical weeks of training (n = 8) Evidence B source
  24 h urine volume 1.8 vs 1.7 L/d, mean arterial pressure 81.1 vs 81.0 mm Hg; urinary sodium excretion matched the extra sodium intake
• A meta-analysis of 36 cluster randomized trials with 66,803 participants found population sodium reduction programs lowered systolic blood pressure by 2.64 mm Hg compared with usual care. — Community, workplace and clinic populations in cluster randomized trials (n = 66803) Evidence A source
  Office systolic BP MD -2.64 mm Hg (95% CI -3.48 to -1.80), benefit in adults but not in children

Safety, limits and interactions

• An umbrella review of 54 meta-analyses found each extra 1.8 oz (50 g) of processed meat a day linked to 17% higher colorectal cancer risk and 72% higher gastric cancer risk, on low to very low certainty evidence. — Systematic reviews and meta-analyses of processed meat intake and health outcomes up to May 2025 (n = 54 meta-analyses) Evidence C source
  Per 50 g/day: colorectal cancer +17%, gastric cancer +72%, prostate cancer +4%, COPD +8%
• A meta-analysis of 31 observational studies linked processed meat intake with a higher risk of colorectal polyps but not of colorectal adenomas. — Observational studies of meat subtypes and precancerous colorectal lesions up to December 2024 (n = 31 studies) Evidence C source
  Colorectal polyps RR 1.65 (95% CI 1.05 to 2.61); colorectal adenoma RR 1.14 (95% CI 0.93 to 1.41)
• In 1995 New Mexico health officials traced a salmonellosis outbreak to beef jerky from one local plant, identifying 93 cases in total. — People in New Mexico who ate beef jerky from one processing plant, 1995 (n = 93) Evidence C source
  2 index cases plus 91 additional salmonellosis cases

Who this works differently for

• A meta-analysis of 35 randomized trials in 2,885 treated hypertensive people found every 100 mmol less daily sodium lowered systolic blood pressure by 6.81 mm Hg. — Hypertensive individuals on constant blood pressure-lowering medication, trials of at least 2 weeks (n = 2885) Evidence A source
  Per 100 mmol lower 24 h urinary sodium: systolic -6.81 mm Hg (95% CI 4.96 to 8.66), diastolic -3.85 mm Hg (95% CI 2.26 to 5.43)
• In a Japanese study of 3,134 older adults, beef jerky was the hardest food group tested, needing 14 lb (6.56 kg) of bite force, and fewer teeth meant fewer people could chew all food groups. — Community-dwelling adults with median age 71, Fujiwara-kyo study 2007 (n = 3134) Evidence C source
  Beef jerky 14 lb (6.56 kg) vs bananas 1.2 lb (0.53 kg); proportion able to chew all five groups fell with tooth loss

The bottom line

In a few young athletes the extra salt looked harmless in the short term. In a randomized trial in 8 trained male runners over three weeks, jerky after exercise left 24-hour urine volume and mean blood pressure unchanged against a standard recovery drink, 81.1 against 81.0 mm Hg. Their kidneys simply excreted the extra sodium. That result comes from eight young athletes and does not carry over to people with high blood pressure or kidney disease. Across 36 cluster trials in 66,803 people, programs that cut salt lowered systolic pressure by 2.64 mm Hg in adults, with no benefit shown in children. Jerky is processed meat, and that evidence is observational. An umbrella review of 54 meta-analyses linked each extra 1.8 oz (50 g) of processed meat a day with a 17 percent higher risk of colorectal cancer and a 72 percent higher risk of gastric cancer. The certainty of that evidence is low to very low, and jerky was never analyzed on its own. A meta-analysis of 31 observational studies linked processed meat with colorectal polyps (RR 1.65, 95% CI 1.05 to 2.61). The link with adenomas did not reach significance (RR 1.14, 95% CI 0.93 to 1.41). Food safety is a real if rare concern. In 1995 New Mexico traced a salmonella outbreak of 93 cases to jerky from one local plant, which tells us it can happen and gives no rate. Teeth matter too. In 3,134 Japanese adults with a median age of 71, jerky was the hardest food tested at 14 lb (6.56 kg) of bite force against 1.2 lb (0.53 kg) for bananas, and fewer teeth meant fewer people could chew everything. We found no card on pregnancy, on children eating jerky or on medicines for beef jerky.
