The World's Vitamin C Champion: The Kakadu Plum
When people think of vitamin C, the first food that comes to mind is often the orange. However, numerous fruits and vegetables contain a higher concentration of this essential nutrient. To answer the question, "which food has the highest in vitamin C?", the clear winner is the Kakadu plum. This small, green fruit native to Australia boasts the highest recorded natural vitamin C content of any food in the world. Some reports indicate concentrations reaching up to 5,300 mg per 100g, far exceeding the vitamin C content of citrus fruits. Indigenous Australians have used this powerhouse fruit for centuries as both a food and a medicinal resource.
Other Superfoods with High Vitamin C
While the Kakadu plum is in a league of its own, several other foods offer an exceptional amount of vitamin C, making them excellent choices for boosting your intake. These include:
- Acerola Cherries: These small, red berries are a tropical powerhouse, delivering approximately 1,650 mg of vitamin C per 1/2 cup (49g). They are also rich in polyphenols with strong antioxidant properties.
- Rose Hips: The small, tangy fruit from the rose plant contains an impressive 426 mg of vitamin C per 100g. They are often dried and used in teas or jams.
- Chili Peppers: Surprisingly, green chili peppers contain a high amount of vitamin C, with one raw green chili providing 109 mg. Red chilies are also a good source.
- Guavas: This tropical fruit is a fantastic source, with a single guava containing 125 mg of vitamin C. It is also high in lycopene and fiber.
- Sweet Yellow Peppers: The vitamin C content of bell peppers increases as they ripen. A single large yellow pepper can provide up to 342 mg, significantly more than a green pepper.
- Black Currants: These tart berries contain 102 mg of vitamin C per half-cup serving.
The Role of Vitamin C in Health
Vitamin C, or ascorbic acid, is an essential water-soluble vitamin that plays a crucial role in many bodily functions. As a potent antioxidant, it protects your cells from damage caused by harmful free radicals, which are linked to the development of chronic diseases like heart disease and cancer. It is vital for the growth, development, and repair of all body tissues, aiding in the formation of collagen, a key protein for maintaining healthy skin, blood vessels, bones, and cartilage. It also improves the absorption of non-heme iron, the type of iron found in plant-based foods. Furthermore, vitamin C plays a significant role in immune function, helping to protect the body against infection.
A Quick Comparison of Vitamin C in Common Foods
To provide a clear picture of how different foods stack up against each other, here is a table comparing the vitamin C content of several popular fruits and vegetables per 100g serving:
| Food | Vitamin C (mg) per 100g | Common Serving Size | % Daily Value* per Serving | Notes |
|---|---|---|---|---|
| Kakadu Plum | 2,907 | 1 plum (15g) | ~484% (based on 90mg DV) | A single plum is an extreme dose. |
| Acerola Cherry | 1,650 | 1/2 cup (49g) | 916% (based on 90mg DV) | Very high concentration. |
| Rose Hips | 426 | 100g | 473% | Often used in dried or tea form. |

| Broccoli (raw) | 89 | 100g | 90% | Offers more than oranges, surprisingly. |
*Based on a 90 mg Daily Value (DV) for adults, but concentrations can vary based on ripeness, growing conditions, and processing.
Maximizing Your Vitamin C Intake
Since the body cannot produce or store vitamin C, it is important to include a consistent supply through your diet. While raw fruits and vegetables are the best sources, cooking and processing methods can affect the vitamin C content. Vitamin C is water-soluble and heat-sensitive, meaning it can break down when exposed to high heat or leached into cooking liquids. Steaming or microwaving can help retain more vitamin C than boiling. For best results, consume vitamin C-rich foods when they are at peak ripeness and eat them raw, whenever possible.
Simple ways to boost your vitamin C:
- Start your day with a fruit smoothie featuring strawberries, kiwis, or a pinch of acerola cherry powder.
- Snack on raw red or yellow bell pepper strips with hummus.
- Add a handful of fresh parsley to your salads, soups, or dishes as a garnish.
- Make a fruit salad with papaya, cantaloupe, and strawberries.
- Opt for steamed or lightly roasted broccoli and Brussels sprouts instead of boiling them.
- Pair vitamin C-rich foods with iron-rich foods, as vitamin C enhances the absorption of non-heme iron.
Conclusion: Variety is Your Best Bet
While the Kakadu plum indisputably has the highest natural concentration of vitamin C, a healthy diet isn't about consuming just one superfood. A varied intake of different fruits and vegetables ensures you get a wide range of essential nutrients, not just vitamin C. Incorporating a mix of these foods into your daily routine is the most effective way to ensure optimal health. Focusing on whole, raw, or lightly cooked foods is key to getting the most out of every bite.
