What You'll Learn
Eat more citrus fruits
Citrus fruits are an excellent source of vitamin C, an essential nutrient that your body needs but cannot produce on its own. Oranges, grapefruits, lemons, limes, and mandarins are all citrus fruits that are high in vitamin C. The vitamin C content in these fruits can vary depending on factors such as type, size, and ripeness, but here are some estimates:
- Oranges: 59-90 milligrams (mg) per 100 g, with one medium orange delivering 83 mg of vitamin C.
- Grapefruit: 80-100 mg.
- Lemon: 30-53 mg per 100 g, with one medium lemon delivering 50% of the daily value (DV).
- Lime: 20-30 mg.
Just one orange or grapefruit can fulfill your daily requirement of vitamin C. You can easily incorporate these fruits into your diet by having an orange as a snack or adding a slice of lemon or lime to your water for a boost of flavor and vitamin C. You can also add citrus fruits to your main dishes, salad dressings, desserts, or beverages. For example, try a quinoa orange and pistachio salad, or add pinwheel slices of oranges or grapefruit as a side to grilled chicken for a Mediterranean twist.
In addition to being a good source of vitamin C, citrus fruits also provide other health benefits. For example, lemon juice acts as an antioxidant, preventing cut fruits and vegetables from browning and lowering blood pressure. Vitamin C in citrus fruits also contributes to the health of your immune system, connective tissue, heart, and blood vessels.

Try red peppers
While oranges are often touted as a vitamin C-rich food, there are several other fruits and vegetables that contain even more of this essential nutrient. One of these is the red bell pepper, also known as a sweet pepper or capsicum.
Native to Central and South America, bell peppers are fruits that belong to the nightshade family. They are low in calories and rich in vitamin C and other antioxidants, making them an excellent addition to a healthy diet. In fact, one medium-sized red bell pepper provides 169% of the Reference Daily Intake (RDI) for vitamin C, making it one of the richest dietary sources of this nutrient.
Bell peppers can be eaten raw or cooked, and they are a great way to add both sweetness and crunch to your meals. They are also a good source of vitamin B6, vitamin K1, and folate, which is a form of vitamin B9. Vitamin B6 is important for forming red blood cells, while vitamin K1 plays a role in blood clotting and bone health. Folate has a variety of functions in the body, including supporting pregnancy and promoting heart health.
In addition to their high vitamin C content, bell peppers also contain the carotenoids lutein and zeaxanthin, which are important for eye health. Consuming adequate amounts of these carotenoids may help protect your retina from oxidative damage and reduce the risk of age-related eye conditions such as cataracts and macular degeneration.
However, it is important to note that while vitamin C is essential for overall health, it is possible to have too much of it. Excess vitamin C in the diet can lead to the formation of kidney stones. Therefore, it is always important to maintain a balanced diet and consult a healthcare professional if you have any concerns or questions about your vitamin C intake.

Eat broccoli
Broccoli is a great food to add to your diet if you're looking to increase your vitamin C intake. This vegetable is packed with nutrients, including vitamin C, which provides numerous health benefits.
Firstly, let's look at the vitamin C content in broccoli. Broccoli contains 65 mg of vitamin C per 100 g. A half-cup of steamed broccoli provides 57% of the daily value (DV) for vitamin C, while one cup of chopped raw broccoli offers 81.2 mg. This already provides a significant amount of your recommended vitamin C intake.
Broccoli can be enjoyed both raw and cooked, but gentle steaming is recommended as it provides the most health benefits. Steaming broccoli may also be more effective at binding bile acids, which could help lower cholesterol levels. If you're eating it raw, make sure you don't consume excessive amounts, as raw broccoli contains goitrogens, which can impair thyroid function in large quantities.
In addition to vitamin C, broccoli is also rich in other essential vitamins and minerals, including vitamins K1 and K, folate, potassium, manganese, iron, and antioxidants. These nutrients work together to promote overall health and well-being.
By incorporating broccoli into your diet, you can boost your vitamin C intake and reap the associated benefits. Vitamin C is important for immune function, bone and cartilage repair, and wound healing. It also acts as an antioxidant, helping to protect the body against various diseases and conditions.

Eat more tropical fruits
Eating more tropical fruits is a great way to increase your vitamin C intake. Tropical fruits like papaya, also known as pawpaw, are an excellent source of vitamin C. One cup of fresh papaya provides nearly 90% of your daily recommended intake of vitamin C. With a buttery texture and a taste similar to a combination of mango and cantaloupe, papaya is a delicious and nutritious option. Another tropical fruit that packs a punch when it comes to vitamin C content is guava. Depending on the variety, a single fresh guava can provide anywhere from 73 mg to 247 mg of vitamin C, which is approximately 200% of your daily recommended intake.
In addition to papaya and guava, there are several other tropical fruits that are rich in vitamin C. Tropical favourites like mango, pineapple, and kiwi are all good sources of this essential nutrient. Mango, with its sweet and tangy flavour, is a tasty addition to any meal or snack, while pineapple adds a burst of sweetness and a unique tropical twist to smoothies, salads, or even grilled dishes. Don't forget the kiwi, a small but mighty fruit that is packed with vitamin C and can be enjoyed on its own or as a delicious topping for your morning porridge or yogurt.
If you're feeling more adventurous, you can explore exotic tropical fruits like camu camu and acerola, which are both considered superfoods due to their exceptionally high vitamin C content. Camu camu, a relatively unknown fruit outside of its native regions, boasts an impressive 1,800 mg of vitamin C per 100 g, along with various beneficial plant compounds. Acerola, a red exotic fruit, contains just under 1,700 mg of vitamin C per 100 g and is also a good source of provitamin A and B vitamins. While fresh acerola may be hard to come by in certain regions, you can still enjoy its nutritional benefits in dried or juice forms.
Lastly, don't underestimate the power of citrus fruits like oranges, grapefruit, limes, and lemons. These familiar tropical treats are widely available and provide a significant portion of dietary vitamin C intake. Oranges, in particular, are a popular choice, with one medium orange delivering 83 mg of vitamin C. So, whether you're enjoying a glass of freshly squeezed orange juice or snacking on a sweet, juicy grapefruit, you're giving your body a healthy dose of vitamin C.

Eat a balanced diet
Eating a balanced diet is crucial to ensuring you get enough vitamin C, a water-soluble vitamin that the body cannot produce or store. While vitamin C deficiency is rare, a diet lacking in fruits and vegetables can lead to insufficient intake.
To maintain a balanced diet rich in vitamin C, include a variety of fruits and vegetables in your daily meals. Citrus fruits, such as oranges, grapefruit, mandarins, and limes, are excellent sources of vitamin C. Oranges, for example, contain 59 mg of vitamin C per 100 g, providing 83 mg in a single medium orange. Other citrus fruits like the Kakadu plum are even more concentrated, delivering 484% of the daily value (DV) of vitamin C in just one plum.
Beyond citrus fruits, there are numerous other vitamin C-rich options to diversify your diet. For instance, Brussels sprouts offer 85 mg of vitamin C per 100 g, with half a cup of steamed sprouts providing 54% of the DV. Similarly, lemon juice acts as an antioxidant, preventing cut fruits and vegetables from browning and offering potential health benefits like lowering blood pressure. Lychees, red acerola cherries, and bananas are also good sources of vitamin C, contributing to your daily requirements.
To maximize the vitamin C content in your meals, opt for quick cooking methods like stir-frying or blanching, which use minimal water and help retain the vitamin. Consuming fruits and vegetables raw is ideal, as cooking and prolonged storage can reduce their vitamin C content. Additionally, choose orange juice packaged in cartons instead of clear bottles to minimize exposure to light, which can also decrease vitamin C levels.
Incorporating vitamin C-rich foods into your meals can enhance the absorption of iron from plant-based sources, such as leafy greens. A small glass of 100% fruit juice or a vitamin C-rich food item included with meals can boost iron absorption. While supplements are available, they are generally unnecessary unless recommended by a healthcare professional, as vitamin C deficiency is uncommon.
