   • 2. Protein
     • builds new cell for growth & replace damage cells
       • Example : fish, beef, chicken
   • 3. Fats
     • acts as a heat insulator & protects internal organs
       • Example : Chocolate, butter, cheese
   • 4. Water
     • maintain body temperature
       • 8 glasses a day
   • 5. Fibre
     • helps the movement of food through digestive tract (to avoid constipation)
       • Example : Fruits, vegetables, Nuts, Barley
   • 6. Vitamins/minerals

3. FACTORS THAT INFLUENCE

   • Age
   • Sex
   • Body size
   • Physical activities
   • Condition of health
   • Surrounding temperature

4. HEALTH PROBLEMS

   • Malnutrition (eating unbalanced diet)
     • eating unbalanced diet
     • Marasmus (carbohydrate)
     • Kwashiorkor (protein)
     • Anemia (iron)
     • Goitre (iodine)
     • Osteoporosis (calcium)
     • Beri-beri (vitamin B)
     • Scurvy (vitamin C)
     • Rickets (vitamin D)
     • Constipation (dietary fibre)
     • Night blindness (vitamin A)
     • Dehydration (water)
   • Obesity (overeating)
   • Anorexia Nervosa (psychology illness-less eating)

5. PLANTS

   • PHOTOSYNTHESIS PROCESS
   • MACRONUTRIENTS
     • Carbon
       • Form carbohydrats, proteins and fats
     • Hydrogen
     • Oxygen
     • Nitrogen
       • form hormones, proteins, chlorophyll
         • stunted growth, leaves small, yellow, drop easily
     • Phosphorus
       • flowers & fruits production
         • poor growth (roots), few flower & fruits
     • Potassium
       • Leaves turn yellow
         • Plants weak and die before maturing
   • MICRONUTRIENTS
     • Copper
     • Boron
     • Zinc
