JAKARTA - Protein is one of the nutrients that are important for the body, especially for those who exercise regularly or undergo muscle building programs. This is because protein serves to form enzymes, energy sources, and maintain body endurance.

Therefore, not a few people deliberately increase protein intake through food or supplements in order to achieve fitness goals. However, it is important to note that the protein needs are different.

One of the organs most affected by excessive protein consumption is the kidneys. When protein is digested, the body produces metabolic waste that must be filtered and removed through the kidneys, which adds to the organ's burden.
