Low-Carb Protein Foods

Every cell in the human body requires protein to function properly, according to Medline Plus, a database provided by the U.S. National Library of Medicine. A diet that does not include sufficient protein can negatively affect the body's ability to maintain bones, muscles and other organs. The body can easily store fats and carbohydrates. On the other hand, the body does not store protein in the same manner. Adequate protein should be consumed every day as part of a healthy diet.

Meat

Red meat, poultry and pork provide significant amounts of protein per ounce and contain no carbohydrates. Choose lean cuts of meat to limit the amount of saturated fat consumed while following a low-carbohydrate diet. When selecting prepared meat products, read product labels carefully and avoid breaded or battered meat products, as well as sauces that have been sweetened or thickened with carbohydrates.

Fish and Seafood

Fish and seafood not only contain protein, but they have the added benefit of being low in both carbohydrates and fat. Cod, flounder, halibut, pollock, tilapia and shrimp have a mild flavor for those who do not like the strong "fishy" taste of fish and other seafood.

Nuts and Seeds

Nuts consist of protein, fiber, fat and many vital nutrients. Although nuts and seeds are high in fat, they provide unsaturated fatty acids, which offer many health benefits. According to the American Dietetic Association, eating nuts may reduce the risk of heart disease, diabetes and cancer. When eaten in moderation, nuts and seeds are a nutritious source of protein. Common choices include almonds, flaxseeds, peanuts, pumpkin seeds, sunflower seeds and walnuts.

Dairy Products

Some dairy products, such as milk and yogurt, contain carbohydrates. Other dairy products, such as eggs and most types of cheese, are low in carbohydrates and high in protein. Read the nutrition facts to determine how many carbohydrates are in a dairy product. Individuals concerned about cholesterol may choose products labeled reduced fat or fat free.

Soy Products

The American Dietetic Association reports that the amount of protein and carbohydrates in soy products varies greatly by brand. Read product labels to identify suitable choices. Tofu, veggie burgers, soy hot dogs and soy cheese provide protein and often have few carbohydrates.
