Question

................ is the best source of vegetable protein.

• A. Soyabean
• B. Rice
• C. Mustard
• D. Groundnut

Hint:

For nutrition-based questions, remember these key associations: Soyabeans for highest plant protein, lentils/pulses for good protein, and grains like rice and wheat primarily for carbohydrates.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
The question asks to identify the best source of protein among the given vegetable/plant-based options.
Step 2: Detailed Explanation:
Let's compare the protein content of the given food items:
(A) Soyabean: Soyabean is renowned for its high protein content. It contains approximately 36-40 grams of protein per 100 grams, which is significantly higher than most other plant sources. It is also a complete protein, meaning it contains all nine essential amino acids.
(B) Rice: Rice is primarily a source of carbohydrates, with very low protein content (around 2-3 grams per 100 grams).
(C) Mustard: Mustard seeds are used as a spice and for oil extraction. While they contain protein, they are not consumed in quantities large enough to be a primary source.
(D) Groundnut (Peanut): Groundnuts are a good source of protein, containing about 25 grams per 100 grams, but this is still lower than soyabean.
Step 3: Final Answer:
Among the given options, soyabean has the highest concentration of protein, making it the best source of vegetable protein.
