LEARNING
OBJECTIVES
 EXPLAIN THE IMPORTANCE OF
DIETARY FIBRES AND WATER
IN THE BODY.
 DEFINE BALANCED DIET.
 EXPLAIN THE IMPORTANCE OF
BALANCED DIET.
 STATE THE CAUSE OF
OBESITY.
 DEFINE DEFICIENCY
DISEASES.
 NAME SOME DISEASES ALONG
WITH THEIR SYMPTOMS
CAUSED BY DEFICIENCY OF
VITAMINS AND MINERALS.

THE VARIOUS
COMPONENTS
PRESENT
IN FOOD ARE
CALLED
NUTRIENTS.
CARBOHYDRATES
PROTEINS
FATS
VITAMINS
MINERALS
CARBOHYDRATES
MAINLY PROVIDE
ENERGY TO OUR
BODY.
SOME SOURCES
OF
CARBOHYDRATES
ARE WHEAT,
RICE, POTATO,
SUGARCANE AND
MAIZE.
WE CAN TEST
PRESENCE OF
STARCH IN A
FOOD ITEM WITH
THE HELP OF
IODINE
SOLUTION.
FOODS
CONTAINING
PROTEINS ARE
OFTEN CALLED
BODY BUILDING
FOODS.
SOME PLANT
SOURCES OF
PROTEINS ARE
BEANS, PEAS,
GRAM,
SOYABEAN AND
LEGUMES.
SOME ANIMAL
SOURCES OF
PROTEINS ARE
MILK, PANEER,
FISH, MEAT
AND EGGS.
WE CAN TEST THE
PRESENCE OF
PROTEINS IN A
FOOD ITEM WITH
THE HELP OF
CAUSTIC SODA AND
COPPER SULPHATE
SOLUTION.
 FOODS
CONTAINING
CARBOHYDRATES
AND FATS ARE
CALLED ENERGY
GIVING FOODS.
 SOME MAIN
SOURCES OF
FATS ARE GHEE,
OIL, BUTTER,
CHEESE AND
MILK.
 WE CAN TEST
THE PRESENCE
OF FATS IN A
FOOD ITEM
WITH THE HELP
OF WHITE
PAPER.
 VITAMINS HELP
IN PROTECTING
OUR BODY
AGAINST
DISEASES.
 THERE ARE
DIFFERENT
KINDS OF
VITAMINS SUCH
AS VITAMIN A ,
B COMPLEX, C,
D, E AND K.
 MINERALS ARE
ESSENTIAL FOR
PROPER GROWTH
OF BODY AND
TO MAINTAIN
GOOD HEALTH.
POTASSIUM,
CALCIUM, IRON,
PHOSPHORUS,
IODINE ARE SOME
EXAMPLES OF
MINERALS NEEDED
BY OUR BODY.

MANY FOOD
ITEMS HAVE
MORE THAN ONE
NUTRIENT.

Milk
Eggs
PROTEINS
VITAMIN D
IODINE
CALCIUM
 FATS
 VITAMIN A
 PHOSPHORUS
 CALCIUM

CARBOHYDRAT
S
VITAMIN B
PHOSPHORUS
PROTEINS
FATS

ALSO KNOWN AS
ROUGHAGE.
MAINLY PROVIDED
BY PLANT
PRODUCTS.
 DOES NOT PROVIDE ANY
NUTRIENT TO OUR BODY, BUT
IS AN ESSENTIAL
COMPONENT OF OUR FOOD.
 HELPS OUR BODY GET RID
OF UNDIGESTED FOOD

 WE GET MOST OF THE WATER
FROM THE LIQUIDS WE DRINK
SUCH AS WATER, MILK AND
TEA.
WE ADD WATER TO
MOST COOKED FOODS.
 MANY RAW FOOD ITEMS
CONTAIN SOME AMOUNT
OF WATER.
 HELPS OUR BODY TO ABSORB
NUTRIENTS FROM FOOD.
 ALSO HELPS IN THROWING
OUT SOME WASTES FROM
BODY.

 WHAT WOULD
HAPPEN IF YOU
KEEP ON EATING
CHOCLATES ALL
THE TIME?

 Our diet
should have all the
Nutrients that our body
needs in right quantities.
 Diet that contains
all nutrients in right
amount with roughage and water is
called BALANCED DIET .

 WHY WE MUST
INCLUDE
DIFFERENT
FOOD ITEMS IN
OUR FOOD?

 DO YOU THINK
THAT PEOPLE OF
ALL AGES NEED
THE SAME TYPE
OF DIET?

 EATING THE RIGHT KIND OF
FOOD IS NOT ENOUGH.
 IT SHOULD BE COOKED
PROPERLY SO THAT ITS
NUTRIENTS ARE NOT
LOST.

 SOME NUTRIENTS GET
LOST IN THE PROCESS
OF COOKING AND
PREPARATIONS.
HOW?

CUTTING AND PEELING
OF VEGETABLES AND
FRUITS.
REPEATED WASHING
OF RICE AND PULSES.
USE OF EXCESS WATER
DURING COOKING AND
THEN THROWN AWAY.

VITAMIN C GETS
EASILY DESTROYED
BY HEAT DURING
COOKING

MALNUTRITION
IMPROPER OR POOR INTAKE OF
NUTRIENTS

 RAHUL EATS FATS RICH
FOOD ALL THE TIME.
 DO YOU THINK HE IS
RIGHT?

FATS GIVE MUCH MORE
ENERGY AS COMPARED TO
CARBOHYDRATES.
IF WE DON’T USE UP THIS
ENERGY, OUR BODIES BUILD
UP A STORE FOR FUTURE
USE.
UNUSUAL FATS GET STORED
IN OUR BODY. THIS
CONDITION IS CALLED
OBESITY.

 OH! I FEEL SO
WEEK AND MY
BONES ACHE. I
MUST INTAKE
OF CALCIUM
AND VITAMINS
IN MY DIET.

UNDER-NOURISHMENT
 WHEN A DIET
LACKS SOME
NUTRIENTS, IT
IS CALLED
UNDER-
NOURISHMENT .

DEFICIENCY DISEASES
 DISEASES THAT
ARE CAUSED
DUE TO LACK
OF NUTRIENTS
OVER A LONG
PERIOD OF
TIME .

DEFICIENCY DISEASES
 IF THE PERSON DO NOT GET
ENOUGH PROTEINS IN HIS/HER
FOOD FOR A LONG TIME, HE /SHE
IS LIKELY TO HAVE STUNTED
GROWTH, SWELLING OF
FACE,DISCOLOURATION OF HAIR,
SKIN DISEASES AND DIARRHOEA .

DEFICIENCY DISEASES
 IF THERE IS DEFICIENCY OF
CARBOHYDRATES AND PROTEINS,
THE GROWTH MAY STOP
COMPLETELY. SUCH A PERSON
BECOMES VERY LEAN AND THIN
AND SO WEAK THAT HE/SHE MAY
NOT BE ABLE TO MOVE.

 ALL
DEFICIENCY
DISEASES CAN
BE PREVENTED
BY TAKING A
BALANCED
DIET.

Night-Blindness
-deficiency of vitamin a
-poor vision, loss of vision in
darkness

Beri-Beri
-deficiency of
vitamin b1

APPEAR SWOLLEN,
MENTAL
DISABILITY
IN CHILDREN

ANAEMIA
-deficiency of IRON
-WEAKNESS

MANY FOOD
ITEMS HAVE
MORE THAN
ONE
NUTRIENT.
BESIDES MAJOR
NUTRIENTS, OUR
BODY NEEDS
DIETARY FIBRES
AND WATER.
 DIETARY FIBRES
( ALSO KNOWN
AS ROUGHAGE)
HELP OUR BODY
GET RID OF
UNDIGESTED
FOOD.
WATER HELPS
OUR BODY TO
ABSORB
NUTRIENTS FROM
FOOD.
Diet that contains
all nutrients in right
amount with
roughage and water
is called BALANCED
DIET .

 DISEASES THAT
ARE CAUSED DUE
TO LACK OF
NUTRIENTS OVER
A LONG PERIOD OF
TIME ARE CALLED
DEFICIENCY
DISEASES .
NIGHT
BLINDNESS IS
CAUSED BY
DEFICIENCY OF
VITAMIN A.
DEFICIENCY OF
VITAMIN B1
CAUSES A
DISEASE
KNOWN AS
BERIBERI.
RICKETS IS
CAUSED BY
DEFICIENCY
OF VITAMIN
D.
DEFICIENCY OF
VITAMIN C
CAUSES A
DISEASE
KNOWN AS
SCURVY.
DEFICIENCY
OF CALCIUM
CAUSES BONE
AND TOOTH
DECAY.
DEFICIENCY
OF IODINE
IN FOOD
CAUSES
GOITER .
DEFICIENCY
OF IRON IN
FOOD
CAUSES
ANAEMIA .
