3.  A diet which contains different
types of food possesing the
nutrients-
Carbohydrate,protein,fats,vitamin
s,minerals and water –in a
proportion to meet the requirement
of the body.
3

4.  Balanced diet achieved by eating variety
of food.
 There is no single food with correct
amount of all essential nutrients.
 Eating a balanced diet requires a certain
amount of knowledge and planning.

5. • The basic composition of balanced diet
is highly variable as it differs from
country to country depending on the
availability of food.
• Social &cultural habits, economic status,
age,sex &physical activity of the
individual largely influence the in take of
diet
5

6. • Nutrion Expert Group from ICMR has
recommended the composition of
balanced diet for Indian.
• They recommended
cereals(rice,wheat,jowar)
pulses,vegetables, roots & tubers,
fruits,milk&milk products,fats &oils
,sugar & ground nuts.
• Additional intake of Meats,fish&egg for
non vegetarian.for vegetarian milk
&pulses. 6

7.  body’s organs and tissues need proper
nutrition to work effectively.
 Without good nutrition, body is more
prone to disease, infection, fatigue, and
poor performance.
 Children with a poor diet run the risk of
growth and developmental problems. Bad
eating habits can continue for the rest of
their lives.

8.  The USDA reports that four of the top 10
leading causes of death in the United States
are directly influenced by diet. These are:
 heart disease
 cancer
 stroke
 diabetes

19.  Severe protein calorie malnutrition characterized
by energy deficiency and emaciation
 Causes stunted growth and wasting of muscles
and tissue
 Develop between the age of 6 months & 1 years
in children who weaned from breast feeding/who
suffer from weakening conditions like chronic
diarrhea.

 Frequent watery diarrhea & acid stools.
 Temperature is abnormal.
 Edema absent.
20

21.  Also called wet-protein energy malnutrition.
 Form of PEM characterized by protein
deficiency.
 Refers to an insufficient protein consumption
but with sufficient calorie intake.
 Usually appear in the age of 12 months when
breast feeding is discontinued.
21

22.  Change in skin pigment.
 Diarrhea.
 Decreased muscle mass.
 Swelling(edema).
 Fatigue.
 Hair changes
 Lethargy.
 Increased & more severe infection due to
damaged immune system.
 Failure to gain weight & grow.
22

23. Treatment strategy divided into 3 stages:
 Resolving life threatening conditions.
- Hospital management
 Resolving nutritional status.
-Dietary management
 Ensuring nutritional rehabilitation
23

24. 1. Hospital Management:
These conditions should be corrected –
hypothermia, hypoglycemia, infections,
dehydration, electrolyte imbalance, anemia &
other vitamin & mineral deficiency.
2. Dietary Management:
Diet from staple foods– inexpensive, easily
digestible, evenly distributed & increased
number of feedings.
3. Rehabilitation:
Nutritional training for mothers- feeding
their children back to health & use local food. 24

25.  Promotion of breast feeding.
 Development of low cost weaning.
 Nutritional education.
 Family planning.
 Immunization.
 Early diagnosis & treatment.

26. • The complex carbohydrate are not digested
by the human enzymes are collectively refers
to as dietary fibers
• soluble fiber-mostly found in fruits & legumes
insoluble fiber- vegetables &grains

41.  Patients with IDD most commonly present
with goiter.
 patients may complaints of compressive
symptoms, such as
 hoarseness,
 shortness of breath,
 cough,
 dysphagia.
41

42.  Cretinism is the most extreme manifestation
of IDD.
 Cretinism can be divided into neurologic and
myxedematous subtypes.
 Both conditions can be prevented by adequate
maternal and childhood iodine intake.
42

43.  Correction of an individual's iodine deficiency
should be instituted at a level recommended by
the World Health Organization (WHO).
 In a nonpregnant adult, 150 mcg/day is sufficient
for normal thyroid function.
 Consultation with an endocrinologist should be
considered when the etiology of thyroid
abnormalities is unclear.
 Thyroidectomy indicated for patients with
compressive symptoms of a large goiter.
43

44.  At a population level, iodine deficiency
disorder (IDD) can be prevented by the
iodization of food products or the water
supply.
 In practice, this is usually achieved by
iodization of salt.
 An alternative in some developing
countries has been the periodic injection
of iodized oil supplements
