While we all know about the importance of incorporating protein into our daily diet, it may be a surprise when we tell you there are two classes of this essential component. Understanding the distinction between them is crucial, especially for vegetarians and those looking to maintain a balanced diet.
Proteins are divided into two classes — class I and class II. Dr Pranav Honnavara Srinivasan, consultant gastroenterologist at Fortis Hospital Bengaluru, explains, “I’ve seen countless diet trends come and go. But one fundamental principle remains constant: protein is essential for building and maintaining a healthy body. However, not all proteins are created equal. Understanding the distinction between class one and class two proteins can empower you to make informed dietary choices and ensure your body gets the complete range of amino acids it needs to thrive.”
What are class one and class two proteins?
Class One Proteins (Complete Proteins): They contain all nine essential amino acids that our bodies can’t produce independently. Think animal-based sources like meat, poultry, fish, eggs, and dairy, says Dr Srinivasan.
Class Two Proteins (Incomplete Proteins): These proteins are like puzzles with missing pieces. They lack one or more of the essential amino acids. Most plant-based protein sources like beans, lentils, grains, and nuts fall into this category.
“Understanding this distinction is crucial because
your body needs all nine essential amino acids to function optimally.
Without them, you could experience a range of health problems, from
muscle wasting and impaired immunity to fatigue and poor wound healing,”
states Dr Srinivasan.
