What is Protein?

Proteins are complex molecules made up of amino acids, which are often described as the building blocks of life. They are essential macronutrients that play a fundamental role in nearly all biological processes in the body. Proteins are vital macronutrients that are necessary for the structure, function, and regulation of the body's cells and tissues. They play a crucial role in various biological processes, and consuming adequate amounts of protein is essential for overall health and well-being.

 

Why Protein is Important for Body?

Protein is crucial for the body as it plays a vital role in building and repairing tissues, making enzymes and hormones, and supporting immune function. It's essential for everyone, not just bodybuilders or athletes. Many hormones are made of proteins or require proteins for their synthesis. Hormones regulate various body functions, including metabolism, growth, and mood. Protein is the building block of muscles. When you exercise, especially strength training, you create micro-tears in your muscles. Protein helps repair these tears, leading to muscle growth and recovery.

Antibodies, which are critical for fighting infections, are proteins. Protein deficiency can weaken the immune system, making you more susceptible to illnesses. Protein-rich foods tend to be more filling than foods high in carbs or fats. Including protein in your meals can help you feel satisfied and may aid in weight management by reducing overall calorie intake. The amount of protein you need depends on various factors such as age, sex, weight, and activity level. Generally, the Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight for adults. However, athletes and those engaged in intense physical activity may need more.
