Importance of Vitamin C in Lung Health and Nutrition

Understanding Vitamin C and Its Health Benefits

Recent research highlights that large doses of Vitamin C may help protect our lungs from the damaging effects of fine particulate matter in the air. This article delves into the functions, sources, and significance of Vitamin C for overall health.

What is Vitamin C?

Vitamin C, scientifically known as ascorbic acid, is a water-soluble vitamin essential for various bodily functions. It plays a crucial role in the growth and repair of tissues throughout the body.

Functions of Vitamin C

This vitamin is vital for several key processes, including:

• Forming collagen, an important protein necessary for the structure of skin, tendons, ligaments, and blood vessels.
• Facilitating wound healing and the formation of scar tissue.
• Repairing and maintaining cartilage, bones, and teeth.
• Enhancing iron absorption from plant-based foods.
• Acting as a powerful antioxidant that neutralizes harmful free radicals in the body.
• Assisting in the production of hormones and neurotransmitters essential for brain and nerve function.

Sources of Vitamin C

The body does not synthesize Vitamin C, making dietary intake crucial. It is primarily found in:

• Citrus fruits such as oranges, lemons, and grapefruits.
• Red and green bell peppers.
• Tomatoes and tomato juice.
• Broccoli and leafy greens.

Some juices and cereals are fortified with Vitamin C. However, it's important to note that Vitamin C is sensitive to heat, and its nutritional benefits can diminish during cooking. Therefore, consuming raw fruits and vegetables is recommended for maximum benefits.

Vitamin C Deficiency and Scurvy

As Vitamin C is not stored in the body, a deficiency can develop quickly. Insufficient intake can lead to scurvy, a condition characterized by symptoms such as:

• Anemia
• Exhaustion
• Spontaneous bleeding
• Pain and swelling in limbs
• Ulceration of gums and loss of teeth

Recognizing these symptoms early is crucial for effective intervention and recovery.
