* Most TNPSC questions are direct-based from basic nutrition concepts, so strong fundamentals will help you score easily.

1.Energy-Giving Nutrients (Carbohydrates)

Carbohydrates are the primary source of energy for the human body.

• They are broken down into glucose during digestion. This glucose provides instant energy for daily activities
• Found in rice, wheat, sugar, potatoes.

To Remember: “Energy = Carbohydrates” (most asked TNPSC question)

2. Vitamins and Their Functions

Vitamins are protective nutrients required in small amounts.

• Vitamin D is called the sunshine vitamin because it is produced when skin is exposed to sunlight
• Vitamin D helps in calcium absorption and strengthens bones

👉 Important vitamins:

• Vitamin A → Vision
• Vitamin B → Metabolism
• Vitamin C → Immunity
• Vitamin D → Bones

3. Body-Building Nutrients (Proteins)

Proteins are essential for growth and repair of body tissues

• They help in muscle development and cell regeneration
• 👉 Found in foods like eggs, pulses, milk, and meat

To Remember: “Body building = Protein” “Growth and repair = Protein” (very important)

4. Vitamin Deficiency Diseases

Lack of vitamins leads to deficiency diseases

• Night Blindness is caused due to Vitamin A deficiency
• Scurvy occurs due to lack of Vitamin C
• Beriberi is caused due to deficiency of Vitamin B1 and affects nerves and muscles
• Pellagra occurs due to lack of Vitamin B3 and is known for 3D symptoms (Dermatitis, Diarrhea, Dementia)
• Rickets is caused by Vitamin D deficiency and leads to weak bones

5.Energy Storage (Fats)

Fats act as a stored source of energy in the body and are used when immediate energy is not available from carbohydrates.

• Fats provide more energy than carbohydrates, making them an efficient energy reserve
• They help in maintaining body temperature and protecting internal organs
• Stored in the body for long-term energy needs
• Found in oils, butter, nuts

To Remember: Fats = Energy storage (long-term energy source)

6.Blood Clotting (Vitamin K)

Blood clotting is an important process that helps stop bleeding during injuries and protects the body from excessive blood loss.

• Vitamin K is essential for the blood clotting process
• It helps in forming clotting factors that seal wounds quickly
• Deficiency of Vitamin K can lead to excessive bleeding

To Remember: Vitamin K = Blood clotting

7.Nutrient for Digestion (Dietary Fiber)

Digestion is supported by certain nutrients that help in smooth movement of food through the digestive system.

• Dietary Fiber helps in proper digestion and bowel movement
• It helps prevent constipation by making waste soft and easy to pass
• Found in fruits, vegetables, and whole grains

To Remember: Fiber = Dietary Fiber = Digestion support

8.Mineral for Strong Bones (Calcium)

Calcium is an essential mineral required for building and maintaining strong bones and teeth in the human body.

• Calcium helps in bone strength and structure
• It works along with Vitamin D for better absorption
• Deficiency of calcium can lead to weak or brittle bones

To Remember: Calcium = Strong bones

9.Vitamin Deficiency – Scurvy (Vitamin C)

Scurvy is a deficiency disease caused due to lack of Vitamin C, which is important for maintaining healthy tissues and immunity.

• Scurvy occurs due to deficiency of Vitamin C
• It leads to symptoms like bleeding gums, weakness, and poor wound healing
• Vitamin C helps in boosting immunity and tissue repair
• Vitamin C is a water-soluble vitamin that is naturally obtained from fresh fruits and vegetables
• Rich sources include citrus fruits like orange, lemon, and sweet lime

To Remember: Scurvy = Vitamin C deficiency

10.Protein-Rich Food (Egg)

Proteins are essential nutrients required for growth, repair, and maintenance of body tissues, and eggs are one of the richest sources of protein.

• Egg is a high-quality protein source containing all essential amino acids
• Other sources include pulses, milk, and meat

To Remember: Protein → Egg (common TNPSC question)

11.Vitamin for Healthy Skin (Vitamin A)

Vitamin A is essential for maintaining healthy skin and proper functioning of body tissues, especially for cell growth and repair.

• Vitamin A helps in keeping skin smooth and healthy
• Deficiency can lead to dry and rough skin

To Remember: Vitamin A → Healthy skin & vision

12.Nutrient that Regulates Body Functions (Vitamins)

Vitamins are essential nutrients that help in regulating various body functions and maintaining overall health.

• Vitamins control processes like metabolism, immunity, and growth
• They are required in small amounts but are very important for proper body functioning
• Help in protecting the body from deficiency diseases

To Remember: Vitamins = Regulation of body functions

13.Mineral for Hemoglobin Formation (Iron)

Iron is an essential mineral required for the formation of hemoglobin, which carries oxygen in the blood.

• Iron helps in production of hemoglobin in red blood cells
• Hemoglobin is responsible for transporting oxygen throughout the body
• Deficiency of iron can lead to anemia and weakness

To Remember: Iron → Hemoglobin formation

14.Vitamin D Deficiency Disease (Rickets)

Rickets is a disease caused by deficiency of Vitamin D, which is essential for bone development and strength.

• Rickets occurs due to lack of Vitamin D
• It leads to weak and soft bones, especially in children
• Vitamin D helps in calcium absorption for healthy bones

To Remember: Vitamin D deficiency → Rickets

15.Vitamin in Citrus Fruits (Vitamin C)

Citrus fruits are rich sources of Vitamin C, which is essential for immunity and overall body health.

• Vitamin C is abundantly found in citrus fruits like orange, lemon, and sweet lime
• It helps in boosting immunity and healing wounds
• Deficiency of Vitamin C can cause scurvy
• Vitamin C is a water-soluble vitamin that is naturally obtained from fresh fruits and vegetables
• Vitamin C found in amla (gooseberry), guava, tomato, and green leafy vegetables
• Fresh and raw foods contain higher Vitamin C content

To Remember: Citrus fruits → Vitamin C

16.Nutrient Needed in Small Amounts (Vitamins)

Vitamins are essential nutrients required in very small amounts, but they play a crucial role in maintaining proper body functions.

• Vitamins are needed in minute quantities for normal growth and health
• They help in regulating body processes like metabolism and immunity
• Lack of vitamins can lead to deficiency diseases
• check for more deficiency diseases (Que 4)

To Remember: Vitamins → Needed in small amounts

17.Nutrient for Repair of Body Tissues (Proteins)

Proteins are essential nutrients that help in the repair and maintenance of body tissues, especially after injury or wear and tear.

• Proteins are responsible for growth and repair of cells and tissues
• They support muscle development and healing process
• Found in foods like eggs, pulses, milk, and meat

To Remember: Proteins → Growth and repair

18.Mineral for Nerve Function (Sodium)

Sodium is an important mineral that helps in proper nerve function and transmission of signals in the body.

• Sodium helps in transmitting nerve impulses
• It maintains fluid balance and muscle function
• Essential for proper communication between brain and body

To Remember: Sodium → Nerve function

19.Vitamin Deficiency – Beriberi (Vitamin B1)

Beriberi is a disease caused due to deficiency of Vitamin B1, which is important for nerve function and energy metabolism.

• Beriberi occurs due to lack of Vitamin B1 (Thiamine)
• It affects the nervous system and muscles, causing weakness
• May lead to fatigue and difficulty in movement

To Remember: Beriberi → Vitamin B1 deficiency

20.Nutrient for Quick Energy (Carbohydrates)

Carbohydrates are the main nutrients that provide quick and immediate energy for the body’s daily activities.

• Carbohydrates are broken down into glucose, which gives instant energy
• They are the primary energy source for the body
• Found in foods like rice, wheat, sugar, and potatoes

To Remember: Carbohydrates → Quick energy

Final Revision Points

• Carbohydrates → Quick and primary source of energy
• Proteins → Growth and repair of body tissues
• Fats → Stored energy (long-term energy source)
• Vitamin A → Vision and healthy skin
• Vitamin B1 → Prevents Beriberi
• Vitamin C → Prevents Scurvy and boosts immunity
• Vitamin D → Helps in bone strength (Rickets if deficient)
• Vitamin K → Helps in blood clotting
