Calories and Nutritions in Beef Jerky

A 100 gram (3.5 oz) serving of lean beef jerky contains 321 calories.

One kilogram (1000 grams or 35.3 oz) of lean beef jerky contains 3210 calories.

A piece of beef jerky weighing 10 grams (0.35 oz) contains 32 calories. The calorie content of one piece of beef jerky varies greatly depending on its size and thickness.

Beef jerky offers some nutritional benefits attributed to its high protein and mineral content, as shown below:

• High in Protein: Beef jerky is a concentrated source of protein, which is essential for muscle building and repair, immune function, and satiety.
• Source of Minerals: It provides important minerals like zinc, crucial for immune function and wound healing, and iron, necessary for oxygen transport in the blood. It also contains phosphorus and selenium. (USDA FoodData Central, Beef Jerky, 25057)
• Provides B Vitamins: Beef jerky contains B vitamins, particularly Vitamin B12, which is vital for nerve function and the formation of red blood cells. (Scientific review on meat nutrients: Wyness, L., et al., 2011. Red meat in the diet: an update.)

Beef jerky has several significant downsides due to processing methods, as listed below:

• High Sodium Content: Commercially produced beef jerky is very high in sodium, used as a preservative and flavoring. Excessive sodium intake is linked to high blood pressure, increasing the risk of heart disease and stroke. (Appel, L.J., et al., 2011. Dietary Approaches to Prevent and Treat Hypertension: A Scientific Statement From the American Heart Association.) The Dietary Guidelines for Americans recommend limiting sodium intake to less than 2,300 milligrams per day. Alternatives include low-sodium jerky options or homemade jerky with controlled salt.
• Contains Nitrates/Nitrites: Many jerkies use sodium nitrite as a preservative to prevent bacterial growth and maintain color. Nitrites can form nitrosamines in the body, which are potentially carcinogenic compounds, particularly linked to colorectal cancer risk when consumed frequently from processed meats. (Bouvard, V., et al., International Agency for Research on Cancer Monograph Working Group, 2015. Carcinogenicity of consumption of red and processed meat.) Choosing "uncured" or "nitrite-free" jerky (which often use celery powder, a natural source of nitrates) is an alternative, though the overall impact difference is debated.
• Processed Meat Classification: Beef jerky falls under the category of processed meat. High consumption of processed meats has been associated with an increased risk of colorectal cancer and cardiovascular disease. (World Cancer Research Fund/American Institute for Cancer Research. Continuous Update Project Expert Report 2018. Meat, fish and dairy products and the risk of cancer.)
• Potential for High Saturated Fat/Sugar: Depending on the cut of beef and the marinade used, jerky can be high in saturated fat and added sugars, contributing excess calories and negatively impacting heart health and blood sugar control.

No, beef jerky is not considered a health food despite the high protein and mineral content, mainly due to its processing, and while Beef Jerky provides zinc, iron, and B12 beneficial for bodily functions including immune support and energy metabolism, these benefits are often overshadowed by the high sodium content typical in most commercial jerky, which negatively impacts heart health by contributing to high blood pressure (Appel, L.J., et al., 2011. Dietary Approaches to Prevent and Treat Hypertension: A Scientific Statement From the American Heart Association.). As  processed meat contains nitrates/nitrites, frequent consumption is linked to increased colorectal cancer risk and potentially negative impacts on digestive health and overall systemic inflammation. The high sodium load offers no benefits for liver or brain health and can contribute to cardiovascular strain. Beef jerky is best consumed infrequently and in small portions as a convenient protein source, rather than a staple health food.

Daily consumption of beef jerky is not recommended. The Dietary Guidelines for Americans recommend limiting sodium intake to less than 2,300 mg per day and minimizing intake of processed meats. The American Heart Association also stresses sodium reduction for heart health. A single standard serving (28 grams or 1 oz) of beef jerky can contain 400-600 mg of sodium or more, representing a significant portion of the daily limit. 

Limiting intake to a single standard serving (28 grams or 1 oz) only occasionally fits better within overall dietary health goals focused on reducing sodium and processed meat intake. Consuming beef jerky daily, especially in large amounts, is discouraged due to high sodium levels and its status as processed meat. Exceeding the recommended daily sodium limit (2,300 mg) is easy with jerky, increasing risks of high blood pressure and cardiovascular issues. Frequent intake of processed meats is linked to higher cancer risk. There is no set "maximum" safe amount for daily consumption, moderation and infrequency are key. 

The calorie content of beef jerky changes based on the fat content of the beef cut used and the amount of sugar added in marinades or rubs. Jerky made from leaner cuts like top round or flank (Lean Beef Jerky, Natural/Uncured, Grass-Fed, Biltong) generally has fewer calories, ranging from 90 to 110 calories per 28-gram (1 oz) serving. Flavored jerkies, especially those with sweet profiles like Teriyaki, Sweet & Hot, or BBQ, can have slightly higher calories due to added sugars in the marinade, pushing them towards the 100-120+ calorie range per ounce. Jerky labeled as thick-cut or made from fattier cuts like brisket will contain more fat and thus more calories, potentially reaching 130 calories or more per ounce. The lowest calorie options are lean, minimally flavored jerkies, while the highest calorie options tend to be those made from fattier cuts or with very sugary marinades.

The origin of jerky traces back to ancient techniques for preserving meat by drying. The word "jerky" derives from the Quechua word "ch'arki," used by indigenous peoples in the Andes region of South America to describe dried, salted meat, often from llama or alpaca. This method allowed meat to be stored for long periods without refrigeration, crucial for sustenance during travel or lean times. European explorers and settlers encountered these practices and adapted them, applying the technique primarily to beef in North America. Drying meat in the sun or over low fires became a common practice for preserving buffalo and cattle meat among Native American tribes and later adopted by pioneers, cowboys, and settlers moving west. It provided a lightweight, nutrient-dense, non-perishable food source ideal for long journeys. The process involved slicing meat thin, removing fat, salting or marinating it, and slowly drying it. Over time, particularly in the 20th century, beef jerky evolved from a survival food into a popular commercial snack in the United States, with various marinades, flavorings (like teriyaki, peppered, hickory smoked), and processing techniques becoming common.
