my new presentation on balanced diet

1. BALANCED DIET

2. Balanced diet
Balanced diet is a combination of different varieties of
nutrients, To maintain good health and physical
efficiency the diet should contain adequate amount of all
nutrients.
On the basis of their predominant functions food are
sometimes grouped as
Energy yielding food – carbohydrates and fat
Body building food – protein
Protective food – vitamins and minerals

3. Carbohydrate
Carbohydrate contain carbon, hydrogen and oxygen. the
main functions of carbohydrate in the body is to provide
energy. The glucose formed by the digestion of starch and
sugar is absorbed mainly in to the blood through the walls
of intestine and carried to the liver.
When carbohydrate are supplied in the diet in excess that
will be converted in to fat and stored as such in the adipose
tissues

4. Uses:
Quick source of energy
It produces heat and energy.
It regulates amount of sugar circulation in the body.
It assist in body’s absorption of calcium.
It helps in lowering cholesterol level and regulate blood
pressure.
One mole of carbohydrates releases 4.1 kcal of energy.
Sources:
Rice, potatoes, sugarcane, wheat, dates, bread sugar, beef
etc

5. Fat
Fat is a component used in the production of several
hormones like compounds which helps to regulate blood
pressure, heart rate , blood vessel constriction, blood
clotting and nervous system.
But too much fat can have a negative impact on health. A
high fat diet can increase the risk of heart disease, high
blood cholesterol, diabetes, liver disease etc.

6. Uses:
Delayed source of energy.
Better source than carbohydrate.
Helps to maintain body temperature.
It lubricates and smoothens the body.
It protects delicate organs against being injured.
Helps to maintain healthy hair ,skin etc.
One mole of fat releases 9.45 kcal of energy.
Sources:
Ghee, cheese, milk products, egg (yolk), oil seeds, fish
oils, Badam, nuts etc.

7. Protein
Proteins are made up of Amino acids. Out of 23 amino acids
eight are essential and they cannot be manufactured in our
body and are to be supplied from outside. proteins are
present in all living tissues – both in plant and animal.
Proteins are very large organic compound, which contain
carbon , hydrogen, oxygen, nitrogen etc.
Even though plants are primary source of protein animal
proteins are considered superior to vegetable source
because they contain all the essential amino acids needed
by the body. the daily requirement of protein is 1gm/kg
weight.

8. Uses:
For building new tissues.
Maintenance of tissues already built and replacement of
regular losses.
Functions as regulatory substances for internal water and
acid base balance.
For lactation
It also produces heat and energy in the absence of
carbohydrate.
Sources:
Plant:- pulses, cereals, papayas, beans, nuts, oil seeds, etc
Animals;- meat, egg(albumin), milk products , fish etc

9. Minerals
Minerals provide material for the growth and
development of bones and teeth. they are also needed
for the growth of body cells, especially the red blood
cells. They are ingredients of various body fluids and are
more important for proper functioning of the circulatory
and nervous system.

10. Uses
They maintain acid balance in the body
They regulates normal system in the heart beat.
They regulate normality in reaction time.
Formation of bones and teeth.
It activates the digestive system and strengthens
muscles and nerves.

11. Major mineral items
1.Iron
Uses:
Activates blood to carry oxygen to the body parts.
Acts as a part of hemoglobin.
Deficiency causes anemia.
sources:
carrot, green leafy vegetables, egg, meat etc

12. 2.Iodine
uses:
It regulates temperature.
For mental development and coloring of hair.
Deficiency create goiter, stunted growth.
sources:
sea foods, iodized salt, egg yolk, onion etc
3.Magnesium
uses:
bones and teeth are formed by magnesium.
deficiency limits muscle contraction.
sources:
Cabbage, figs, almonds, sea foods, meat etc

13. 4.Calcium
Uses:
Formation of bones and teeth
It controls the action of heart, blood, nerves
Physical retardation takes place in its absence.
Asthma, skin disease appear in the absence of
calcium.
Sources:
Fish, milk, cheese, egg yolk, orange, vegetables, curd,
carrots etc

14. Vitamins
Food contains certain chemical substances in small amounts.
these are called vitamins. Vitamins plays a key role in most
chemical reactions in the body but they do not provide
energy . Many of the cell reactions are carried through
enzymes. it is made by the combination of vitamins and
minerals. if one item happens to be missing that enzyme
cannot be formed and some important functions of the body
cannot be carried out. so no one can survive without
vitamins.
On the basis of the characteristics of their solubility vitamins
are categorized as
1.Water soluble – B complex and C
2.Fat soluble - A, D,E, K

15. Uses:
It facilitates the digestive action.
For proper growth of the body.
It produces disease resistance and destroying
capacity.
For proper physical reproduction.
Sources:
Green vegetables, milk, egg, dhal, lemon,
grapes, liver, banana

16. WATER
Water is a medium in which most of the chemical reactions
connected with metabolism and life take place. man
cannot live without water and it is best fluid to drink in any
form.75% of the body consists of water. An average adult
need to take 2 to 3 liters of water a day because the same
amount is eliminated from the body in the form of urine,
perspiration and water vapors in the process of breathing.

17. uses:
It helps in elimination of poisonous elements and
waste products from the body in the form of sweat
and urine.
It helps in digestion of food.
It regulates the body temperature.
