Non-essential amino acids are those that the body can synthesize on its own, meaning they do not need to be obtained directly through the diet. In contrast, essential amino acids must be consumed because the body cannot produce them; they are critical for various physiological functions, including protein synthesis, hormone production, and immune function.

In this case, the correct answer is that non-essential amino acids are not considered essential because the body is capable of producing them. Examples of non-essential amino acids include alanine, aspartic acid, and glutamic acid, among others. This classification helps in understanding dietary requirements and the role of macronutrients in nutrition.

Histidine, tyrosine, and leucine, on the other hand, are classified either as essential or conditionally essential, meaning they must be consumed under certain circumstances when the body's needs are elevated. Recognizing the difference between essential and non-essential amino acids is fundamental in nutrition and dietetics, as it helps in creating balanced dietary plans that meet individuals' needs based on their health and lifestyle.
