L-ascorbic acid, commonly known as vitamin C, is one of the most beneficial and talked about vitamins. The human body cannot naturally produce this vitamin. However, it is highly essential for proper bodily functions.

Foods that contain vitamin C include citrus fruits, vegetables, and other dietary supplements. The following write-up will provide you with a detailed overview of the health benefits of vitamin C rich foods and how they assist the body in day-to-day functioning.

The human body cannot synthesise vitamin C naturally. Hence, it has to be supplied through food items that are loaded with vitamin C.

Among such foods items, fruits and vegetables containing vitamin C are probably the only sources. The daily recommended limit of vitamin C intake for adults is 65-90 milligrams.

If you want to know which food has the most vitamin C, make sure to go through the following section. However, keep in mind that the actual amount of vitamin C might vary.

Citrus fruits, berries, vegetables, and other foods contain vitamin C, a water-soluble vitamin sometimes referred to as ascorbic acid and ascorbate. Your body needs vitamin C to produce muscle, blood vessels, cartilage, and bone collagen. 

You must obtain vitamin C from your diet because your body cannot make it. Citrus fruits, berries, potatoes, tomatoes, peppers, cabbage, and spinach all contain vitamin C. Additionally, vitamin C can be taken orally as a supplement, usually as chewable pills and capsules.

Fresh fruits and vegetables are just one of the numerous natural sources of vitamin C. The most abundant sources consist of:

• Indian gooseberry (700 mg/100 g)

• Citrus fruits, such as limes, oranges and lemons

• Tomatoes and tomato juice

• Potatoes

• Green and red peppers

• Kiwifruit, strawberries and cantaloupes

• Green leafy vegetables such as broccoli

• Fortified cereals

Food loses vitamin C when it is cooked and stored for extended periods. Microwaving or steaming can reduce its content. The daily requirement for vitamin C is met by eating an adequate amount of fresh fruits and vegetables, which equates to five or more servings of various fruits and vegetables.

Look at these top vitamin C rich foods designed to feed your body and excite your taste buds. This list includes colourful vegetables, juicy fruits, nuts and seeds, and animals and seafood full of nutrients.

Vegetables are also reliable sources of vitamin C. Here’s a list of top vitamin C vegetables that can help you to fulfil your daily recommended level of vitamin C requirement:

These values can vary slightly depending on factors like ripeness and cultivation methods. Here's a list of fruits rich in vitamin C, along with their approximate content per 100 grams:

Seeds and nuts are not typically significant sources of vitamin C compared to fruits and vegetables. However, here are some seeds and nuts along with their approximate vitamin C content per 100 grams:

Animal-based foods and seafood are generally not significant sources of vitamin C, as they are primarily found in plant-based sources. However, here are some animal and seafood options that contain trace amounts of vitamin C:

Vitamin C offers a wide range of health benefits. Here are some of the major benefits of consuming vitamin C:

Helps in Boosting the Immune System

One of the most well-known benefits of vitamin C is that it helps to strengthen the immune system. A study conducted by the University of Helsinki shows that significant vitamin C intake lowers the duration of viral infection.

In addition, a review published in November 2017 in Nutrients says that vitamin C aids in strengthening the immune system by preventing oxidative stress.

Vitamin C eliminates harmful foreign microbes and reduces the possibility of tissue damage. Therefore, including vitamin C food sources in daily diet can help in boosting the overall immunity.

Maintain Blood Pressure Level

High blood pressure can lead to major heart ailments along with the possibility of stroke. Vitamin C fruits and vegetables can work wonders in keeping blood pressure under control. These food items help in reducing the level of triglyceride. Triglyceride, commonly known as bad cholesterol, is the primary factor behind high blood pressure levels.

Lemons, for instance, are a great solution for high blood pressure and hypertension. It helps in making the blood vessels soft and flexible, thereby facilitating a smooth flow of blood.

Collagen Synthesis for a Youthful Skin

Collagen is an important protein that plays a vital role in the production of connective tissues. Connective tissue is found in abundance in hair, nail, skin, and other body organs. The presence of sufficient vitamin C facilitates the production of collagen.

Collagen helps in maintaining the elasticity of the skin, which tends to decrease with age. Adequate collagen is essential for firm and healthy skin tissues. In addition, vitamin C is a popular beauty ingredient in many cosmetic products for a glowing and even skin tone.

Enhanced Iron Absorption

Iron is an essential mineral for the body. It aids the body in proper growth and development and helps in improving the distribution of oxygen throughout the body. Moreover, iron also assists in the production of various hormones.

However, iron found in plant sources (nonheme iron) can be quite difficult for your body to absorb effectively. This is where vitamin C steps in. According to Harvard Health Publishing, consuming fruits and vegetables rich in vitamin C can help in better absorption of nonheme iron.

Helps in Brain Functioning

Research shows that the synthesis of neurotransmitters and cognitive functions depend greatly on vitamin C. Neurotransmitters help the brain in sending messages to various parts of the body. Therefore, proper synthesis of neurotransmitters is associated with increased brain function.

Protects the Eyes

Studies show that vitamin C aids in slowing down the spread of macular degeneration, which is an eye disorder that leads to loss of vision. A report published in the Archives of Ophthalmology suggests that those who took 500 milligrams of vitamin C in their daily diet along with vitamin E, zinc and beta-carotene, showed reduced chances of macular degeneration by almost 25% and reduction of visual acuity by almost 15%.

Packing a punch of health benefits, vitamin C-rich foods are beneficial for a strong and healthy body. Here are the many health benefits of vitamin C: 

Here are some health benefits of incorporating vitamin C-rich foods into your diet:

• Stronger Immune System: Vitamin C supports the production of white blood cells, which are key fighters in your body's immune defence against infections.

• Improved Iron Absorption: Vitamin C enhances the absorption of iron, especially from plant-based sources.

• Faster Wound Healing: Vitamin C is crucial for collagen production, a protein essential for healthy skin, connective tissues, and wound healing.

• Reduced Disease Risk: Vitamin C's antioxidant properties help combat free radicals, potentially lowering the risk of chronic diseases like heart disease and certain cancers.

• Overall Health and Well-being: Vitamin C plays a role in various bodily functions, contributing to healthy bones, teeth, and cartilage. 

Vitamin C is an essential element for the body, and you must consume it on a daily basis to prevent its deficiency. The unavailability of adequate vitamin C in the body can disrupt normal bodily functions and lead to various ailments. Here are some of the signs that might indicate vitamin C deficiency:

Delayed Wound Healing

Vitamin C is responsible for the production of collagen in the body. Collagen helps in promptly healing the cuts and wounds. With vitamin C deficiency, the body loses its ability to generate adequate collagen, which results in the slow healing of wounds. In cases of severe deficiency, old wounds may reopen.

Bleeding Gums

Inadequate vitamin C leads to weakened gum tissues and inflamed blood vessels around the gums. This causes red and swollen gums, which eventually results in the falling of teeth.

Iron Deficiency Anaemia

Vitamin C is responsible for the systemic absorption of iron in the body. Insufficient vitamin C levels can lead to poor iron absorption resulting in iron deficiency anaemia. The signs of iron deficiency anaemia include pale skin, fatigue, pounding of the heart, sore tongue, unexplained hair loss, chest pain, and more.

Other key signs include:

• Dry and rough skin

• Poor immunity

• Sudden weight gain

• Weak bones 

• Swollen joints

To sum up, you must make sure to have enough vitamin C rich foods to maintain a healthy level of the vitamin. You can add several fruits and vegetables to your daily diet to meet the daily recommended vitamin C intake requirement. Health experts suggest following the red, green, and yellow rules for vitamin C intake, which would include bell peppers, green leafy vegetables, and colourful citrus fruits.

Note: Apart from fruits and vegetables, there is rarely any other food source that contains vitamin C.

By incorporating these vitamin C rich foods into your diet in various ways, you can ensure that you're getting an adequate intake of this essential nutrient to support your overall health and well-being.

• Fresh Fruit Salad: After daily meals, eat fresh fruit salad with oranges, strawberries, kiwis, mangoes, and grapefruits. You can enjoy them as snacks, add them after meals, or blend them into smoothies for a refreshing treat.

• Vegetable Salads: Make vegetable salads using bell peppers (especially red and green ones), broccoli, Brussels sprouts, tomatoes, and spinach. These vegetables can be raw in salads, stir-fried, or roasted as side dishes.

• Citrus Juices: Drink freshly squeezed citrus juices like orange, grapefruit, or lemonade. Just be mindful of added sugars in store-bought juices and opt for freshly squeezed ones whenever possible.

• Cooked Foods: Some vegetables, like bell peppers and broccoli, retain their vitamin C content even when cooked. Include these vegetables in stir-fries, soups, stews, or roasted vegetable medleys to add flavour and nutrients to your meals.

• Herbs and Spices: Certain herbs and spices, such as parsley, thyme, and chilli peppers, are also good sources of vitamin C. Use them generously in your cooking to add flavour and boost your vitamin C intake.

• Fortified Foods: Look for fortified foods enriched with vitamin C, such as cereals, fruit juices, and plant-based milk alternatives. These can be convenient options for meeting your daily vitamin C requirements.

Consuming adequate vitamin C from a balanced diet with plenty of fruits and vegetables is important to minimise these risks. Not getting enough vitamin C can lead to various health risks and complications:

• Severe deficiency leads to scurvy.

• Decreased intake may prolong wound healing and increase infection risk.

• Deficiency can cause joint and muscle pain.

• Insufficient intake may result in dry, prematurely aged skin. 

• Without enough vitamin C, there is a risk of developing iron deficiency anaemia. 

While vitamin C is generally considered safe and well-tolerated, excessive intake can lead to certain side effects:

• Digestive Issues: Consuming too much vitamin C can cause digestive discomforts such as diarrhoea, nausea, vomiting, and abdominal cramps.

• Kidney Stones: High doses of vitamin C can increase the risk of developing kidney stones, particularly in individuals prone to this condition. 

• Iron Overload: Excessive vitamin C supplement intake in combination with high iron intake can lead to iron overload, especially in individuals with hereditary hemochromatosis or other conditions predisposing them to iron accumulation.

• Interference with Medical Tests: High doses of vitamin C can interfere with certain medical tests, like blood glucose tests and stool occult blood tests, leading to inaccurate results. 

• Increased Oxidative Stress: Excessively high doses of vitamin C may promote oxidative stress in the body. This can have harmful effects on cells and tissues.

• Gastroesophageal Reflux Disease (GERD): Excessive vitamin C intake in supplements may worsen GERD symptoms due to its acidic nature.

Whether or not you should take a vitamin C supplement depends on several factors, including your diet, lifestyle, and health status. If you have a balanced diet rich in fruits and vegetables, you may already be getting enough vitamin C naturally. A supplement might be beneficial if you have a limited intake of these foods or have certain health conditions that increase your need for vitamin C, such as smoking or pregnancy.

It's important to note that while vitamin C supplements are generally safe for most people when taken in recommended doses, excessive intake can lead to adverse effects such as digestive discomfort or kidney stones. Therefore, it's always wise to consult with a healthcare professional before starting any new supplement regimen to ensure it's appropriate for your needs and health status.
