Highest source of vitamin-C?

Appeared in: NORCET 2 -2021 (Shift-2)

Explanation

Amla (Indian gooseberry) is exceptionally rich in Vitamin C, making it the most potent source among the choices.
It contains approximately 600 mg of Vitamin C per 100 grams of fruit.
This concentration is substantially higher than that found in citrus fruits like oranges (30-68 mg/100g) and lemons (63 mg/100g).
The vitamin C in amla is also highly stable due to the presence of tannins, which protect it from being destroyed by heat or oxidation.

Option B: Banana is a very poor source of Vitamin C, providing only about 7 mg per 100g.
Option C: While oranges are a well-known source of Vitamin C, they contain significantly less than Amla, with a content of about 30-68 mg per 100g.
Option D: Lemon contains a good amount of Vitamin C (approximately 63 mg per 100g), but this is nearly ten times less than the amount found in Amla.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Nutritional sources of Vitamin C as background academic context rather than a clinical decision trigger.
Nurses advise patients on dietary sources of Vitamin C for promoting wound healing, boosting immunity, and preventing scurvy. Knowing the most potent sources like Amla is crucial for effective patient education.
A patient with delayed wound healing, frequent infections, or bleeding gums might be assessed for Vitamin C deficiency. Recommending Amla can be a cost-effective and potent dietary intervention.
What if the patient cannot tolerate the sour taste of Amla? The nurse could suggest Guava, which is the next richest common source (around 212 mg/100g) and is often more palatable.

How to Approach the Question

This is a factual recall question that asks you to identify the 'highest' or 'best' option from a list.
First, identify the core concept of the question, which is the dietary source of 'Vitamin C'.
Next, recall or deduce the relative amounts of Vitamin C in each of the options provided: Amla, Banana, Orange, and Lemon.
Even if you don't know the exact numbers, general nutritional knowledge suggests that Amla is exceptionally high in Vitamin C.
Compare the values to find the maximum. Amla (600 mg/100g) is significantly higher than Lemon (63 mg/100g), Orange (50 mg/100g), and Banana (7 mg/100g).
Select the option with the highest value to correctly answer the question.
