Bovril is a meat extract that is used as a flavoring for a range of foods, including stews and soups, and is sometimes used as a spread for toast. Bovril is sold with a thick, gelatinous consistency, but it can be diluted for other uses by mixing it with water. Bovril is relatively low in calories, although it is high in sodium, so it may not be appropriate for all diets.
Bovril is very low in calories, as each 12 g serving contains just 22 calories. This makes Bovril lower in calories than many other condiments and spreads, such as jelly, which contains 50 calories per tablespoon, or beef gravy, which contains 103 calories in a 4 oz. serving. If you are dieting, you can burn off the calories in Bovril quite easily; six minutes of weightlifting or eight minutes of walking at a 2 mph pace would be sufficient to burn 22 calories.
Bovril is a fat-free food, which helps keep the calorie content low, as fat provides 9 calories per gram.
Bovril is a low-carbohydrate food, as each 12 g serving contains just 1 g of carbohydrates. Carbohydrates provide your body with energy, so consuming them can be beneficial for athletic endeavors. However, some research suggests that limiting carbohydrate intake can be helpful, particularly for weight loss; a study from the July 2008 edition of "The New England Journal of Medicine" found carbohydrate-restricted diets more effective for weight loss than fat-restricted diets.
Bovril is rich in protein. Each 12 g serving of this food contains 5 g of protein, a nutrient your body uses to build muscle, skin and other tissues. Protein is essential for life, so the Institute of Medicine suggests eating at least 0.8 g for every kilogram, or about 8 g for every 20 lbs., of your body weight each day.
Bovril is high in sodium, as a 12 g serving contains 540 mg. While some sodium is needed for proper health, too much sodium is unhealthy. The 2010 Dietary Guidelines for Americans suggests eating no more than 2,300 mg each day; one serving of Bovril provides more than 23 percent of that amount. If you have high blood pressure, kidney disease or diabetes, you should limit daily sodium intake to 1,500 mg.
