Lysine and the Pescatarian Diet
Lysine is one of the nine essential amino acids that the human body cannot synthesize on its own, meaning it must be obtained through the diet. It plays a crucial role in protein synthesis, hormone and enzyme production, and the absorption of calcium. Lysine is also important for immune system function and in the production of collagen and elastin. It is typically found in high-protein foods such as meat, dairy products, eggs, and certain plant-based foods like beans and lentils.
