The Importance of Vitamin C
Vitamin C, also known as ascorbic acid, is a water-soluble vitamin vital for human health. Unlike many animals, humans must obtain vitamin C from their diet as they cannot produce it internally. Its crucial roles include:
- Collagen synthesis: Essential for producing collagen, which maintains the health of skin, blood vessels, and bones. Deficiency weakens tissues, causing issues like bleeding gums.
- Antioxidant protection: Acts as an antioxidant, shielding cells from damage by free radicals.
- Iron absorption: Enhances the body's ability to absorb iron from plant-based foods.
- Immune function: Supports the immune system's various cellular functions.
Top Fruits to Fight Scurvy
Many fruits are excellent sources of vitamin C, with some exceeding the content found in citrus fruits. Including a variety of these in your diet is a flavorful way to prevent scurvy.
Fruits with exceptionally high vitamin C content
Fruits like Kakadu plums and acerola cherries are among the richest sources of vitamin C. Guavas, blackcurrants, kiwifruit, and strawberries also provide significant amounts.
Powerful Vegetables that Combat Deficiency
Vegetables are also valuable sources of vitamin C. To maximize intake, consume them fresh or with minimal cooking, as heat can degrade the vitamin.
Best vegetable sources of vitamin C
Bell peppers (especially yellow ones), chili peppers, broccoli, Brussels sprouts, cauliflower, and dark leafy greens like kale are notable for their vitamin C content. Potatoes, while lower in concentration, have historically been important in preventing scurvy due to their availability.

To preserve vitamin C in foods, consider these tips: eat foods raw when possible, steam vegetables lightly, and minimize reheating.
Other Dietary Considerations
Besides fresh produce, some other sources contain vitamin C, such as raw liver and fortified foods. However, fruits and vegetables remain the most reliable and beneficial sources.
Conclusion
