Deficiency of which type of substances leads to malnutrition?

Amino acids are the building blocks of proteins, which are essential for numerous bodily functions, including muscle repair, immune function, and the production of hormones and enzymes. A deficiency in amino acids can lead to malnutrition because proteins are crucial for growth, maintenance, and overall health. Insufficient protein intake can result in a range of health issues, including muscle wasting, weakened immunity, and impaired metabolic processes.

While vitamins, fatty acids, and minerals are also important for maintaining health and preventing malnutrition, the specific impact of amino acids on human physiology is profound. Proteins derived from amino acids play a central role in nearly every biological process, which underscores the importance of having an adequate supply of these substances in the diet. Without enough complete proteins providing the necessary amino acids, the body cannot perform vital functions effectively, leading to malnutrition.
