Which statement about food and nutrients is not correct?
Appeared in: RRB Staff Nurse Mumbai-2015
Explanation
The statement 'Starch found in cereals is an example of proteins in food' is factually incorrect.
Starch is a complex carbohydrate (a polysaccharide), which serves as the primary energy-providing nutrient in cereals like rice, wheat, and maize.
Proteins are a distinct class of macronutrients composed of amino acids. Their main role is in building and repairing body tissues, not primarily as starch.
The food pyramid in the image correctly places cereals, bread, and pasta at the base, representing the carbohydrate group, which should form the largest part of the diet.
Why Other Options Were Wrong
Option A: This statement is correct. Food serves important psychological functions, providing comfort, security, and satisfaction, which are known as the emotional aspects of eating.
Option C: This statement is correct. Vitamins are essential organic compounds required in small quantities for the body's growth, maintenance, and normal metabolic functions.
Option D: This statement is correct. Water is crucial for numerous bodily processes, including the digestion of food, absorption of nutrients, and the formation of feces for the elimination of waste.

Clinical Relevance
Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification and functions of major nutrients (carbohydrates, proteins, vitamins, water) as background academic context rather than a clinical decision trigger.
A nurse must educate patients on balanced nutrition. Correctly identifying food groups is fundamental for creating diet plans for patients with conditions like diabetes (carbohydrate counting), renal failure (protein restriction), or malnutrition.
Understanding the role of water in waste elimination is critical when managing constipated patients, especially post-operative or elderly individuals. Encouraging adequate fluid intake is a key nursing intervention.
What if? If a patient with celiac disease consumes cereals like wheat, the gluten (a protein) would trigger an autoimmune reaction. This highlights that while the primary nutrient is a carbohydrate, other components like proteins can have significant clinical implications.
How to Approach the Question
First, read the question carefully and note the negative keyword 'not correct'. This means you are looking for the false statement among the options.
Evaluate each option based on your foundational knowledge of nutrition.
Option A discusses the psychological role of food. Recall if food has emotional functions. Yes, it does (e.g., comfort food).
Option B makes a specific claim: 'Starch...is an example of proteins'. Analyze this. Is starch a protein? No, starch is a well-known carbohydrate. This is a likely candidate for the incorrect statement.
Verify the remaining options. Option C states vitamins are for growth and function. This is a core fact. Option D states water is for waste elimination. This is also a core fact.
Conclude that the statement classifying starch as a protein is the incorrect one.
