What is Protein?

Protein is a complex molecule that is fundamental to our health, growth, and development Comprising smaller components known as amino acids, protein is indispensable for constructing various bodily tissues, including muscles, skin, and hair [1]. Besides being a building block, protein also plays a crucial role in a myriad of biochemical reactions within the body, such as enzyme reactions, immune responses, and DNA replication [2]. In essence, protein takes center stage in nearly every physiological function and procedure.

Types of Protein

Typically, proteins can be classified into two major types based on their source – animal protein and plant protein. Animal-derived proteins, like those found in meat, dairy, and eggs, earn the title of ‘complete proteins’ due to their inclusion of all essential amino acids that our bodies cannot independently generate. On the other hand, plant proteins like beans, lentils, and quinoa are often called ‘incomplete proteins’ because they lack one or more essential amino acids, though there are exceptions like soy and buckwheat [3].

History and Discovery of Protein

The term “protein” was coined by the Swedish chemist Jöns Jacob Berzelius back in 1838 [4]. However, the concept of protein as a vital body component was recognized much earlier. In the 18th century, French chemist Antoine Fourcroy and others noted the presence of a substance in egg whites which they called ‘albumen’ [5]. They identified it as a compound that was also present in other tissues and fluids in the body. This was essentially our first glimpse of protein. However, it wasn’t until the 20th century that the structure and function of proteins were more thoroughly understood, paving the way for modern protein research and nutritional understanding.

Importance of Protein

As a fundamental constituent within each cell of our bodies, protein undertakes roles in tissue formation and repair, enzymatic and hormonal production, and pivotal involvement in all bodily operations [6]. With a deep understanding of its importance, we can make better dietary choices, ensuring we receive an adequate amount of this essential nutrient.

Role of Protein in the Human Body

The human body utilizes protein to construct and mend tissues, produce enzymes and hormones, and generate various other body chemicals. It forms an integral part of bones, muscles, cartilage, skin, and blood. At the biochemical level, proteins partake in nearly all cellular processes [7]. They are vital for metabolic reactions, immune response, protein synthesis, and cell division. Some proteins even serve as neurotransmitters, assisting in transmitting messages in the brain [8],[9].

How Much Meat Protein Should Be Eaten In A Day?

The daily requirement of meat-derived protein fluctuates based on variables such as age, gender, activity level, and overall health condition. According to the Dietary Guidelines for Americans, an average adult woman needs about 46 grams of protein per day, while an average adult man needs approximately 56 grams [10]. It’s worth highlighting that these figures represent averages and that individual needs may diverge. For instance, athletes or those engaging in intensive physical activity might require more protein.

Remembering that protein intake shouldn’t be solely dependent on meat is crucial. Alternative protein sources like legumes, dairy, and whole grains contribute to a comprehensive diet. Always consult a healthcare professional or a registered dietitian to understand the optimal protein intake for your specific needs.
