**Question:** Sorghum contains good amount of -

A. Vitamin B1
B. Iron
C. Fiber
D. Calcium

**Core Concept:** Sorghum is a cereal grain cultivated primarily for human consumption and livestock feed. It is known for its nutritional value and is often referred to as a superfood.

**Why the Correct Answer is Right:** Sorghum is a rich source of several nutrients, including vitamin B1. Vitamin B1, also known as thiamine, plays a crucial role in various physiological processes, such as carbohydrate and fat digestion, and maintaining cardiovascular health.

**Why Each Wrong Option is Incorrect:**

A. Vitamin B1 (thiamine) is not the only nutrient in sorghum that contributes to its nutritional value. Other nutrients, such as fiber and iron, are also present. However, vitamin B1 is the correct answer because it is a key component of sorghum and contributes to its overall nutritional profile.

B. Iron is present in sorghum, but it is not the primary nutrient that makes sorghum a good food option. While iron is essential for proper red blood cell formation and oxygen transport, vitamin B1 is a more relevant factor considering the context of a single question about the nutritional content of sorghum.

C. Fiber is an important component of sorghum, contributing to digestive health and satiety. However, the question specifically asks about the good amount of a particular nutrient in sorghum, and vitamin B1 is the correct answer.

D. Calcium is essential for maintaining bone health, but calcium content is not the primary factor that makes sorghum a beneficial food option. Vitamin B1 is the correct answer for this question, as it highlights a key nutritional aspect of sorghum.

**Clinical Pearl:** Sorghum is a versatile and nutritious grain that provides various health benefits due to its rich content of nutrients like vitamin B1, fiber, and minerals. Incorporating sorghum into one's diet can contribute to overall health and wellbeing.
