How much protein in a 12oz steak?


The amount of protein in a 12oz steak is a common question among individuals who are conscious of their protein intake. Protein is an essential macronutrient that plays a crucial role in building and repairing tissues, supporting immune function, and maintaining overall health. In this article, we will explore the protein content of a 12oz steak and its nutritional implications.

Protein Content in a 12oz Steak

The protein content in a 12oz steak can vary depending on the type of meat and its preparation. On average, a 12oz steak contains approximately 84 grams of protein. However, it is important to note that this value can fluctuate based on factors such as the cut of meat, fat content, and cooking method.

Types of Steak and Protein Content

Different cuts of steak have varying protein contents. Here are a few popular cuts and their approximate protein content per 12oz serving:

Filet Mignon: Filet mignon is a tender and lean cut of beef. It typically contains around 84 grams of protein per 12oz serving.

Ribeye: Ribeye is a well-marbled and flavorful cut of beef. It usually contains approximately 78 grams of protein per 12oz serving.

Sirloin: Sirloin steak is a versatile cut that is relatively lean. It generally contains around 72 grams of protein per 12oz serving.

It is worth mentioning that these values are approximate and can vary depending on the specific steak and its fat content.

Protein Quality in Steak

In addition to the protein content, the quality of protein in steak is also important to consider. Steak is considered a high-quality protein source as it contains all the essential amino acids required by the body. Essential amino acids are those that the body cannot produce on its own and must be obtained through diet.

Furthermore, steak is rich in heme iron, which is highly bioavailable and easily absorbed by the body. Iron is essential for the production of red blood cells and the transportation of oxygen throughout the body.

Other Nutritional Considerations

While steak is a good source of protein, it is also important to consider other nutritional aspects. A 12oz steak typically contains a significant amount of fat, including saturated fat. Consuming excessive amounts of saturated fat can have negative effects on cardiovascular health. Therefore, it is recommended to balance protein intake with a variety of other nutrient-dense foods such as fruits, vegetables, whole grains, and healthy fats.


A 12oz steak generally contains around 84 grams of protein, depending on the cut and preparation. Steak is a high-quality protein source that provides essential amino acids and heme iron. However, it is important to consume steak in moderation and consider its fat content in the context of a balanced diet.
