Verified step by step guidance

Step 1: Understand the concept of nutritionally incomplete proteins. These are proteins that lack one or more of the essential amino acids required for proper human nutrition.

Step 2: Recall the difference between essential and nonessential amino acids. Essential amino acids cannot be synthesized by the body and must be obtained through the diet, while nonessential amino acids can be produced by the body.

Step 3: Analyze the options provided in the question. Carbohydrates and fatty acids are not directly related to the classification of proteins as nutritionally complete or incomplete. Nonessential amino acids are synthesized by the body and are not a limiting factor in incomplete proteins.

Step 4: Recognize that the defining characteristic of nutritionally incomplete proteins is their deficiency in one or more essential amino acids, which are crucial for protein synthesis and overall health.

Step 5: Conclude that the correct answer is 'Essential amino acids,' as these are the nutrients that nutritionally incomplete proteins are low in.
