In this tutorial, we will learn about:

1. Role of vitamin C in the body.

2. Food sources of vitamin C.

3. Ways to increase vitamin C intake in our diet.

Image: Vitamin C symbol

Image: Collage of functions

Vitamin C is a water soluble vitamin.

It plays a very important role in several body functions.

Image: Collagen

Image: Collage of bones, muscles, skin

Image: Collage of Skin, hair, blood vessels, bones

It is essential for the synthesis of collagen which acts like a cement.

It holds the bones, muscles, skin and the whole body together.

Tissues of our body like skin, hair, blood vessels and bones have collagen.

Vitamin C helps in recovery after a muscle or skeletal injury.

It helps in the healing of wounds.

It is also required for maintaining healthy skin.

Another role of vitamin C is that it acts as an antioxidant.

Antioxidants are substances that protect our body from damage by free radicals.

Free radicals are substances that are naturally produced in the body.

They become harmful only when they become excessive.

Pollution, smoking, alcohol, harmful chemicals increase free radicals production.

This results in cancer, diabetes, heart diseases and cataract.

Gif: Vitamin C preventing free radicals from attacking

Vitamin C reduces the formation of free radicals in the body.

Thus, protecting our cells from damage.

Image: Boosting of immune system

Image: Fighting against infection

Image: Collage of cold, cancer, heart disease

Vitamin C also strengthens our immune system.

It helps in fighting infections and protecting against other diseases.

For example: common cold, cancer and heart diseases.

Image: Collage of bones

Image: Synthesis of hormones

Image: Dopamine

Image: Adrenaline

Image: Nor- adrenaline

Image: Collage of stress and fright

Vitamin C helps in bone formation.

It also helps in the synthesis of a few hormones.

For example: dopamine, adrenaline, noradrenaline.

These hormones help the body respond to stress or fright.

In addition, vitamin C enhances the absorption of non-heme iron in the body.

Non-heme iron is a form of iron which is mostly present in plant based foods.

For example: green leafy vegetables, seeds, nuts and beans.

Consuming too little vitamin C can increase the risk of iron deficiency.

This may result in anemia which is known as iron deficiency anemia.

Image: Fever

Image: Fatigue

Deficiency of vitamin C can result in scurvy.

Early signs of scurvy are uneasiness, fever and fatigue.

Image: Swollen and bleeding gums

Images: Loose teeth

Image: Bruising and bleeding

Image: Pain and swelling in joints

Image: Coiled shaped hair

Other symptoms are swelling and bleeding in gums and loosening of teeth.

Poor healing of wounds and bruises and bleeding on the skin is visible.

Swelling and pain in the joints may also arise.

The hair becomes dry and coiled.

Image: Collage of dry skin, mood changes, poor immunity Other signs of deficiency are dry skin, mood changes and poor immunity.
Image: Anemia due to low vitamin C Iron deficiency anemia can also occur due to vitamin C deficiency.
Image: Collage of Vitamin C recommendations

Image: Vitamin C recommendations for babies

Image: Vitamin C recommendations for older children

Image: Vitamin C recommendations for adolescents

Image: Vitamin C recommendations for adult females

Image: Vitamin C requirements in adult males

Let us now have a look at the daily vitamin C recommendation.

For babies upto 12 months of age, 25 milligrams per day is recommended.

For children who are 1-10 year old, 40 milligrams per day is recommended.

For adolescents, 45-75 milligrams per day is recommended.

For adult females, it is 75 milligrams.

90 milligrams is recommended for adult males.

Image: Vitamin C requirements in pregnancy and lactation

Image: Vitamin C recommendations for lactating mothers

The requirements are higher during pregnancy and lactation.

Pregnant women should have 85 milligrams of vitamin C per day.

Lactating mothers should have 120 milligrams per day.

Image: Collage of dietary sources of vitamin C Let me now tell you the food sources of vitamin C.
Image: Collage of vitamin C rich fruits and vegetables

Image: Collage of guava and gooseberry

Certain fruits and vegetables are good sources of vitamin C.

Among fruits, gooseberry and guava are the richest sources.

1 medium-sized guava gives around 300 milligrams of vitamin C.

1 gooseberry has nearly 60 milligrams of vitamin C.

Image: Vitamin C content of orange

Other examples are: Bengal currant, indian jujube and raw mango.

Fruits like oranges, lemons and sweet limes are also good sources.

1 tablespoon of lemon juice has approximately 8 milligrams of vitamin C.

1 medium orange has about 40 milligrams.

Even green leafy vegetables have an adequate amount of vitamin C.

For example: leaves of drumstick (moringa), amaranth, radish and mustard.

Fenugreek leaves, agathi leaves are other examples.

Image: Collage of things that results in loss of Vitamin C

Image: Cooking on high flame

Image: Keeping fruits in open

Image: Cooking in lots of water

Image: Discarding water

Image: Storing food for a long time

There are certain factors which decrease the vitamin C content of the food.

It is sensitive to heat and water.

It is lost if cooked at high temperature or exposed to prolonged sunlight.

Cooking in excessive water and discarding the water also results in loss.

Storing food in the refrigerator for a long time reduces the vitamin C content.

Image: Raw vitamin C rich food

Image: Cooking on low flame

Image: Steaming versus boiling

Image: Less loss of vitamin C with steaming

Thus, many of the vitamin C rich foods are best consumed raw.

This way you get the maximum amount of vitamin C from it.

If they are cooked, they should be cooked on low flame for shorter durations.

Steam or sauté vegetables instead of boiling.

Upon steaming, the loss of vitamin C is the least.

Image: Avoid repetitive heating of food

Image: Cooking with minimum water

Image: Avoid storing in refrigerator for long time

Do not repetitively heat the food.

Cook with minimum or no water.

Avoid storing and refrigerating food for a long time.

Image: Collage of ways to increase vitamin C content

Image: Fresh versus spoiled vegetables

Image: Ripe versus raw fruits

Let us learn some ways to increase our daily intake of vitamin C.

Eat fresh fruits and vegetables.

Pick the raw fruits as they have more vitamin C.
