Vitamin C Rich Foods – Health Benefits, Deficiency & More


June 20, 2022

Vitamin C, also known as ‘Ascorbic Acid’, is a water-soluble vitamin and a powerful antioxidant. It protects the body from free radicals, which play an essential role in ageing. In addition, it helps strengthen the blood vessels and muscles. However, unlike other animals, humans cannot synthesise this vitamin internally. Hence, our vitamin C intake depends only on natural foods and artificial supplements. 

You can obtain reasonable amounts of vitamin C from certain fruits and vegetables. Citrus fruits such as oranges, strawberries, gooseberries and grapes and leafy vegetables like cabbage, cauliflowers, etc., are excellent sources of this vitamin.

In addition, potatoes, red peppers, parsley and Brussel sprouts contain considerable amounts. However, make sure to cook food briefly at low temperatures to preserve the vitamin in your food.

Vitamin C Requirements

The requirement of Vitamin C content in one’s body varies according to age. For instance, the United States Food and Nutrition Board (FNB) study suggests the appropriate vitamin C intake for adults (18 years and above) as 65-75 mg of the vitamin, whereas for infants (up to 12 months), it is 40-50 mg.

Proven Benefits of Vitamin C

Let us look at some fantastic benefits of including vitamins in your diet.

Speeds up the healing of wounds

Vitamin C leads to collagen production, a protein present in connective tissues of the skin, muscles, and tendons. So regular intake of this vitamin is helpful in wound healing. Vitamin C speeds up the healing process, whether the wound is a minor or deep cut, broken bone or burns.

Vitamin C is the principal water-soluble antioxidant found in plasma. It is a two-fold action; it oxidises itself and regenerates and activates iron or copper. Then it removes the damaging oxidising agent. The process helps in speeding up the wound healing process.

Role in neurological conditions

Vitamin C is crucial in protecting the brain and nervous system against the harmful effects of stress. If you take them in optimum amounts, it synthesises the regulation of stress hormones. Additionally, high nutrient levels may also reduce the progression of dementia and Alzheimer’s disease. That is because it helps increase beta-carotene and lycopene.

As per the study results, vitamin C may change the course of neurological diseases and display potential therapeutic roles. 

Helps battle asthma

People with chronic asthma can significantly benefit from Vitamin C. It is essentially an antioxidant and antihistamine that enables improved lung function. In addition, it decreases the oxidative stress placed on airway tissues which prevent hypersensitivity-causing triggers. Studies suggest that 1000-2000 mg of the vitamin daily can effectively reduce histamines production, a significant cause of inflammation in asthma patients.

Boosts immunity

Various studies suggest that Vitamin C deficiency can decrease the body’s resistance to specific pathogens. So, including it in your diet helps fight various infections and allergies, strengthening the immune system.

Reduces risk of cataracts

Direct exposure to sunlight leads to the generation of free radicals in the eye lens, which causes cataracts or blindness in the elderly. These free radicals occur as the fluid inside the eye and prevent oxidation that leads to eye lens clouding. Vitamin C intake may successfully eliminate free radicals. In addition, it boosts vitamins in the eye field. Therefore, vitamin C reduces the risk of cataracts in older people and improves their vision.

Aids in the treatment of cancer

High vitamin C dosage increases the effect of cancer-eliminating drugs utilised in chemotherapy. Unlike other medications, this vitamin is target-specific. Hence, it doesn’t damage the other body cells. Moreover, a study suggests that increased intake of nutrients can also reduce the risk of mouth, lungs, throat, vocal cords, colon, oesophagus, and rectum cancer.

Reduces the risk of stroke

Vitamin C kills the free radicals, which damage the walls of arteries. Therefore, they help reduce the chances of a stroke. Besides this, vitamin C consumption also lowers cholesterol and improves blood flow.

As per research, plasma vitamin C modifies the association between hypertension and the risk of stroke. So, add adequate vitamin C to your diet to avoid the risk of stroke.

Cures Lead Toxicity

Vitamin C deficiency may lead to higher amounts of lead in the bloodstream. In addition, it severely affects mental and physical development and can even prove fatal. Hence, people who smoke should add a daily dose of vitamin C supplements to their routine. It reduces lead levels and can alleviate lead toxicity.

Helps in weight loss

Adequate levels of Vitamin C can foster weight and fat loss by increasing body fat oxidation during exercise and enhancing metabolism. So, including citrus fruits or leafy vegetables in your diet before or after your exercise routine can fasten fat loss.

According to a study, individuals who consume more vitamin C with adequate exercise oxidise 30% more fat than individuals with low consumption levels.

Effective for arthritis symptoms

People who have arthritis take vitamin C supplements to raise vitamin levels in their bodies. It helps reduce pain, swelling of joints and inflammation as well. It also assists in lowering uric acid in the blood. In addition, the production, repair, and maintenance of cartilaginous tissues enhance as a result of collagen production by Vitamin C. However, balance in its intake is crucial because a high dose can worsen the condition.

Beneficial for skin problems

Clinical trials prove that vitamin C prevents skin sagging, reduce wrinkles, protects from UV rays and improves skin elasticity. Therefore, it is widely used in face packs, creams, and moisturisers today.

It helps maintain healthy gums.

Vitamin C deficiency can cause periodontal disease, a severe form of gingivitis. It develops because lower vitamin C levels can weaken connective tissues and quickly break down the capillaries. Conversely, a regular and moderated intake of Vitamin C can prevent bleeding gums and improve oral health.

Hence, vitamin C keeps the connective tissues of the gums healthy and strong. As a result, they hold your teeth in place and reduce tooth wear in early childhood.

Regulates blood sugar

According to research, regular and long-term intake of Vitamin C supplements aids the regulation of blood sugar levels in patients who have Type 2 Diabetes. In addition, the vitamin stimulates the insulin mechanism, reduces fasting blood glucose, thereby enhancing the efficacy of the treatment.

Prevents Scurvy 

Scurvy is quite a rare occurrence today. However, vitamin C or ascorbic acid deficiency is one of the leading causes of scurvy. It causes weakness, anaemia, gum disease, and skin problems. In addition, collagen, formed by vitamin C, is vital in connective tissues. Therefore, consuming 10 g of Vitamin C every day can help prevent scurvy.

Great for healthy hair

Dry and flaky skin can lead to the clogging of hair follicles. As a result, it prevents hair growth and leads to hair fall. Vitamin C helps fight the bacteria in the scalp and prevents premature greying of hair.

Research also suggests that vitamins and minerals play a significant role in hair loss.

Prevents Common Cold

Vitamin C foods are not a cure for the common cold, but recent studies suggest that they help prevent it. In addition, they do not worsen into serious complications, such as pneumonia and lung infections.

Helps Prevent Iron Deficiency

Iron is an essential nutrient that serves multiple functions. It builds red blood cells and assists the transportation of oxygen throughout the body. Vitamin C absorbs the iron from your diet. It further converts it into an easily absorbable form. 100 mg of vitamin C can improve iron efficiency in the body by 67%. According to research, it helps lower the chances of contracting anaemia. 

Protects Cells from Free Radical Damage

Our bodies produce free radicals due to cigarette smoke, air pollution, excessive sunlight, and normal metabolism. Vitamin C is an antioxidant that protects your cells from free radical damage. As a result, it stops untimely ageing and prevents diseases like cancer and heart diseases, as mentioned above. In other words, it avoids the harmful effects of pollution around us.
