Dried meat like beef jerky and biltong is a genuinely high-protein snack, but it comes with real tradeoffs. A 40-gram serving (a typical snack portion) delivers about 13 grams of protein along with meaningful amounts of iron and zinc, making it one of the most nutrient-dense portable foods you can carry. The catch: most commercial dried meat is loaded with sodium, and it falls squarely into the category of processed meat that the World Health Organization has linked to colorectal cancer.
What You Get From a Serving
Dried meat is essentially concentrated animal protein. When you remove the water from beef or turkey, the nutrients pack into a much smaller volume. A 40-gram portion of beef jerky or biltong provides roughly 25% of your daily protein needs, 17% of your daily iron, and 26% of your daily zinc. That protein-to-calorie ratio is hard to beat in a shelf-stable snack.
Protein is also the most filling of the three macronutrients. Your body uses 20% to 30% of the calories from protein just to digest it, compared to 5% to 10% for carbohydrates and nearly zero for fat. Protein-rich foods consistently score highest on satiety indexes, meaning they keep you feeling full longer per calorie consumed. For people trying to manage their weight, this makes dried meat a more effective snack than chips, crackers, or trail mix. High-protein diets also help preserve lean muscle mass during weight loss, which keeps your resting metabolism from dropping as sharply.
The Sodium Problem
Salt is what makes jerky shelf-stable and flavorful, but the amounts are significant. A single one-ounce serving of commercial beef jerky contains roughly 22% of the 2,300 mg daily sodium limit set by federal guidelines. The American Heart Association’s ideal target is even lower, at 1,500 mg per day for most adults. Two or three servings of jerky can put you at or above that ceiling before you’ve eaten anything else that day.
Excess sodium raises blood pressure over time, which increases the risk of heart disease and stroke. If you’re eating dried meat regularly, the sodium content is the most immediate dietary concern to manage. Some brands run significantly lower than others, so checking labels matters. Biltong, which is air-dried rather than heat-dried and often uses a simpler spice blend, sometimes contains less sodium than American-style jerky, though this varies by brand.
Processed Meat and Cancer Risk
The WHO classifies processed meat as a Group 1 carcinogen, meaning there is sufficient evidence that it causes cancer in humans. Beef jerky and biltong are specifically named in that classification. The primary concern is colorectal cancer: an analysis of data from 10 studies estimated that eating 50 grams of processed meat daily increases colorectal cancer risk by about 18%. An association with stomach cancer has also been observed, though the evidence there is less conclusive. Globally, about 34,000 cancer deaths per year are attributed to diets high in processed meat.
To put 50 grams in perspective, that’s roughly two servings of jerky, which many people could easily eat in one sitting. Group 1 classification doesn’t mean dried meat is as dangerous as smoking (another Group 1 carcinogen). It means the strength of evidence that it causes cancer is equally well established, not that the magnitude of risk is the same. Still, daily consumption clearly carries more risk than occasional snacking.
Nitrites and Nitrosamines
Many commercial dried meats are cured with sodium nitrite, which prevents bacterial growth and gives the meat its characteristic color. The health concern isn’t the nitrite itself at typical doses. It’s what nitrite can become: when it reacts with proteins during high-heat processing or digestion, it can form compounds called nitrosamines. The International Agency for Research on Cancer has stated that nitrite, under conditions that produce these compounds, is “presumably carcinogenic to the human body.” Most nitrosamines are classified as probable carcinogens, with links to cancers in specific organs.
High nitrite intake can also interfere with thyroid function by reducing iodine absorption, potentially leading to thyroid enlargement over time. These effects require sustained high exposure, not a single bag of jerky, but they’re worth knowing about if dried meat is a daily habit.
Are “Uncured” Options Better?
Products labeled “no nitrites added” or “uncured” typically use celery powder, beetroot, or other nitrate-rich vegetables as natural curing agents. Celery powder is the most common, and under controlled fermentation it can produce nitrite concentrations of 15,000 to 20,000 mg per kilogram. In other words, it’s still producing nitrite in the meat. It’s just arriving through a vegetable source rather than a synthetic one.
This doesn’t mean these products are worthless. Some research suggests that the antioxidants naturally present in vegetable-based curing agents may partially offset nitrosamine formation. But if your concern is nitrite exposure specifically, “uncured” labels can be misleading. Your body processes the nitrite the same way regardless of its origin.
Jerky vs. Biltong
The two most popular styles of dried meat differ in how they’re made. Jerky is typically marinated and then dried with heat, sometimes smoked. Biltong is cured in vinegar and spices and air-dried without heat, a process that can take several days. Because biltong skips high-heat processing, some of its nutrients may be better preserved, and the conditions for nitrosamine formation are less favorable.
Turkey jerky tends to be lower in fat than pork jerky or beef biltong, which matters if you’re watching saturated fat intake. The protein content across all types remains high. Differences in overall nutritional quality depend more on the specific recipe, marinade, and additives than on whether the product is called jerky or biltong.
Making Dried Meat at Home
If you want to control sodium and skip preservatives entirely, homemade jerky is straightforward. The key safety step is heating the meat to 160°F (or 165°F for poultry) before dehydrating it. The USDA recommends this pre-cooking step because dehydrators alone may not reach temperatures high enough to reliably kill E. coli or Salmonella. Steam or roast the meat first, then dry it in strips.
Homemade jerky lets you cut the sodium by half or more compared to commercial versions, skip nitrites entirely, and choose leaner cuts. The tradeoff is shelf life: without preservatives, homemade jerky should be refrigerated and eaten within one to two weeks.
How to Include It Wisely
Dried meat works well as an occasional high-protein snack, especially when you need something portable and shelf-stable. It’s a reasonable choice after workouts, during travel, or when your other options are vending machines. The protein density and satiety benefits are real.
The risks scale with frequency. Eating jerky a few times a month is a very different proposition than eating it daily. If you’re a regular consumer, rotating in lower-sodium brands, choosing products without added sugars (some jerky contains surprisingly high amounts), and balancing your overall processed meat intake across the week are practical steps that reduce your exposure to the compounds that carry the most concern.
