Which nutrient is not found in egg?

Appeared in: NORCET 3 - 2022 (Shift-2)

Explanation

Eggs contain almost all essential nutrients except for Vitamin C and carbohydrates.
Vitamin C, or ascorbic acid, is a water-soluble vitamin that is primarily found in plant-based foods like citrus fruits (oranges, lemons), berries, tomatoes, and green leafy vegetables.
Animal products, including eggs, meat, and dairy, are not significant sources of Vitamin C.

Option A: Iron is present in eggs, mainly concentrated in the yolk. A large egg provides a small but valuable amount of this mineral.
Option B: Eggs are a well-known source of high-quality, complete protein, containing all nine essential amino acids. Both the egg white and yolk contain protein.
Option D: Fat is a key component of eggs, found almost exclusively in the yolk. This includes both saturated and unsaturated fats.

Visual 1: Infographic: A diagram showing the nutritional breakdown of a whole egg, highlighting the presence of protein, fat, and iron, and the absence of Vitamin C.
Visual 2: Chart: A comparative chart showing sources of Vitamin C (e.g., oranges, guava, amla) versus foods that lack it (e.g., eggs, meat).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Nutritional composition of eggs as background academic context rather than a clinical decision trigger.
Nurses often provide dietary counseling. Knowing the nutritional composition of common foods like eggs is fundamental to advising patients on balanced diets.
For patients with iron-deficiency anemia, a nurse can recommend eating iron-rich foods like eggs and suggest pairing them with a source of Vitamin C (like orange juice) to enhance iron absorption.
What if a patient is a vegetarian? The nurse would need to recommend alternative high-protein sources (like lentils, beans, tofu) and plant-based iron sources, again emphasizing the pairing with Vitamin C.

How to Approach the Question

First, identify the keyword 'not' in the question. This indicates you are looking for the substance that is absent.
Recall the basic nutritional profile of an egg. Think about what eggs are famous for (protein) and what they contain (fat and minerals in the yolk).
Consider each option:
Iron: Is it in eggs? Yes, in the yolk.
Protein: Is it in eggs? Yes, a primary component.
Fat: Is it in eggs? Yes, in the yolk.
