Question

Which one of the following has highest amount of carbohydrates ?

• A. Lettuce
• B. Carrot
• C. Peas
• D. Knol Khol

Hint:

As a general rule in nutrition, seed-based vegetables (like Peas and Corn) store starch for embryo growth, making them much richer in carbohydrates than leafy, stem, or root vegetables.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Vegetables differ significantly in their proximate nutritional composition, specifically their moisture, protein, lipid, and carbohydrate content, based on which plant part is consumed (leaves, roots, or seeds).

Step 2: Detailed Explanation:
Let us compare the typical carbohydrate content (per \(100\text{ g}\) of edible portion) of the listed vegetables:
1. Lettuce (Lactuca sativa) (A): A leafy green vegetable composed of over \(95\%\) water. It contains only about \(2.9\text{ g}\) of carbohydrates per \(100\text{ g}\).
2. Carrot (Daucus carota) (B): A root vegetable containing around \(9.6\text{ g}\) of carbohydrates per \(100\text{ g}\), primarily in the form of simple sugars (sucrose, glucose).
3. Peas (Pisum sativum) (C): These are leguminous seeds. Unlike leafy or root vegetables, seeds store high reserves of energy to support germination. Consequently, green peas contain approximately \(14.4\text{ g}\) of carbohydrates per \(100\text{ g}\), largely in the form of complex starches.
4. Knol Khol (Kohlrabi) (Brassica oleracea) (D): A stem vegetable containing around \(6.2\text{ g}\) of carbohydrates per \(100\text{ g}\).
Thus, Peas have the highest carbohydrate content among the given choices.

Step 3: Final Answer:
Therefore, Peas contain the highest amount of carbohydrates.
