Mr. Dinindu Lokugamage

(North Colombo Teaching
Hospital

3. There are two main types
of Nutrients.
Macronutrients
Micronutrients

4. There are three main
macronutrients.
 Proteins
 Carbohydrates
 Fats(lipids)

5. Why Human Body needs
Protein?
Protein is used by our bodies
for growth and repair.
Our bodies will use protein as
an energy source if there is
nothing to use.

6. Why Human body needs
Proteins?

7. How we find Proteins?

8. Prof. Lakmi Fernando
(University of Colombo)

9. Chemical structure of a
protein is a chain of alfa-
Amino acids
Alfa-amino acids

17.  Growth and maintenance
 Causes biochemical reactions
 Maintain proper PH
 Bolsters immune health
 Transports and store nutrients
 Provides energy
IMPORTANCE OF
PROTEINS

18.  Protein is required for growth and
maintenance of tissue.
 Our body’s protein needs are dependent
upon our health and activity level

19. Enzymes are proteins that allow key
chemical reactions to take place within
body.

20. Protein act as a buffer system , helping
your body maintain proper PH values of the
blood and other bodily fluids

21. Proteins form antibodies to protect your
body from foreign invaders , such as
disease-causing bacteria and viruses

22. Some proteins transport nutrients
throughout your entire body,while others
store them.

23. Proteins can serve as a valuable energy
source but only in situations of fasting ,
exhaustive exercise or inadequate calorie
intake

24. Problems related
to protein
deficiency
Dr. Damith
District General Hospital
Gampaha

25. problems
 Weight loss
 Muscle weakness
 Swelling
 Low blood pressure and low heat rate
 Nutrient malabsorption
 Liver problems
 Anemia
 Weak Immunity
 Food carvings
 Muscle and joint pain

26. Weight Loss
 a reduction of the total body mass,
due to protein deficiency.

27. Muscle weakness
Muscle weakness means lack of strength
in muscles.

28. Low Blood Pressure and low
heart rate
Low blood pressure define as readings
lower than 90mmHg and low heart rate is
define as readings below 60 beats a
minute.

29. Weak Immunity
 The immune system defends the body from
developing potentially harmful diseases and
conditions caused by bacterial, parasitic, fungal
and viral infections. When the immunity system
get weak you can be caught easily by diseases.

30. Anemia
 A condition in which there is a deficiency of red
cells or of hemoglobin in the blood, resulting in
pallor and weariness.

31. Food Carvings
 A food craving (also called selective hunger) is an
intense desire to consume a specific food, and is
different from normal hunger.
