MCQ Detailed View

Vitamin B1, also known as thiamine, is an important vitamin that helps the body turn food into energy. It also supports nerve, muscle, and heart function. When someone doesn’t get enough vitamin B1, they may develop a disease called beriberi.

There are two main types of beriberi:
1. **Wet beriberi** – affects the heart and circulatory system. It can cause shortness of breath, swelling in the legs, and heart failure.
2. **Dry beriberi** – affects the nerves. It can lead to muscle weakness, nerve damage, and even paralysis in severe cases.

Beriberi is more common in people who:
- Eat mostly white rice or processed carbs without B1 enrichment
- Have alcohol addiction (alcohol stops the body from absorbing B1)
- Have long-term illnesses or very poor diets

To prevent beriberi, it is important to eat foods rich in vitamin B1 such as:
- Whole grains (brown rice, oats)
- Nuts and seeds
- Eggs
- Legumes (beans, lentils)
- Lean meats (especially pork)

Now, let’s look at the other options:
- **Myopia** is short-sightedness and is not caused by vitamin deficiency.
- **Bone Infection** (osteomyelitis) is usually caused by bacteria.
- **Rickets** is caused by vitamin D deficiency, not vitamin B1.

So the correct answer is **Beriberi**, a disease directly linked to vitamin B1 deficiency. It is preventable and treatable, but if ignored, it can become very serious.
