2. BALANCED DIET
DEFINITION
A balanced diet is defined as one
which contains a variety of food in
such quantities and proportions
that the need for energy, amino
acids, vitamins, minerals, fats,
carbohydrate and other nutrients is
adequately met for maintaining
health, vitality and general
wellbeing .
5. IMPORTANCE OF
BALANCED DIET
ďąBalanced Diet leads to a good
physical and a good mental health.
ďąIt helps in proper growth of the body.
ďąAlso, it increases the capacity to
work
ďąBalanced diet increases the ability to
fight or resist diseases.
7. Carbohydrates are macronutrients,
they are one of the three main ways
the body obtains energy, or calories
They are called carbohydrates
because, at the chemical level, they
contain carbon, hydrogen and
oxygen. The recommended daily
amount (RDA) of carbs for adults is
135 grams, while pregnant women
need at least 175 grams.
Carbohydrates
8. Carbohydrates
â˘Carbohydrates provide fuel for the central nervous
system and energy for working muscles. They also
prevent protein from being used as an energy source
and enable fat metabolism
â˘Carbohydrates are classified as simple or complex
Simple carbohydrates contain just one or two sugars,
such as fructose (found in fruits) and galactose (found
in milk products). These single sugars are called
monosaccharides. Carbs with two sugars â such as
sucrose (table sugar), lactose (from dairy) and maltose
(found in beer and some vegetables) â are called
disaccharides
9. Carbohydrates
Simple carbs are also in candy, soda and
syrups. However, these foods are made with
processed and refined sugars and do not
have vitamins, minerals or fiber. They are
called "empty calories" and can lead to
weight gain
Complex carbohydrates (polysaccharides)
have three or more sugars. They are often
referred to as starchy foods and include
beans, peas, lentils, peanuts, potatoes, corn,
parsnips, whole-grain breads and cereals.
10. GOOD CARBOHYDRATE
ď Low or moderate in calories
ď High in nutrients
ď Devoid of refined sugars and refined grains
ď High in naturally occurring fiber
ď Low in sodium
11. ďLow in saturated fat
ďVery low in, or devoid of,
cholesterol and trans Fat

15. Protein
Protein is a macronutrient that is
essential to building muscle mass. It is
commonly found in animal products,
though is also present in other sources,
such as nuts and legumes.
Protein is the basic component of living
cells and is made of carbon, hydrogen,
oxygen, nitrogen and one or more chains
of amino acids. The three types of
proteins are fibrous, globular, and
membrane.
16. Protein is an important
component of every cell in the body.
... Your body uses protein to build and
repair tissues. You also use protein to
make enzymes, hormones, and
other body chemicals. Protein is an
important building block of bones,
muscles, cartilage, skin, and blood.

20. Fat
â˘Fats are one of the three
main macronutrients, along
with carbohydrates and proteins. Fat
molecules consist of primarily carbon and
hydrogen atoms and are
therefore hydrophobic and are soluble in
organic solvents and insoluble in water.
Examples include cholesterol, phospholipids,
and triglycerides.
21. â˘Dietary fats are essential to
give your body energy and to
support cell growth. They
also help protect your organs
and help keep your
body warm. Fats help your
body absorb some nutrients and
produce important hormones, too.

25. VITAMINS
A vitamin is an organic molecule (or related set of
molecules) that is an essential micronutrient that
an organism needs in small quantities for the proper
functioning of its metabolism. Essential nutrients
cannot be synthesized in the organism, either at all
or not in sufficient quantities, and therefore must be
obtained through the diet.
26. ⢠The thirteen vitamins required by human metabolism
are: vitamin A (as all-trans-retinol, all-trans-retinyl-esters,
as well as all-trans-beta-carotene and other provitamin A
carotenoids), vitamin B1 (thiamine), vitamin B2 (riboflavin),
vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin
B6 (pyridoxine), vitamin B7 (biotin), vitamin B9 (folic
acid or folate), vitamin B12 (cobalamins), vitamin C (ascorbic
acid), vitamin D (calciferols), vitamin E
(tocopherols and tocotrienols), and vitamin K (quinones).
VITAMINS
27. ⢠The four fat-soluble vitaminsâA, D, E, and
Kâare stored in the bodyâs fatty tissues.
⢠The other nine vitamins are water-soluble
and therefore must be replenished regularly
because they are removed from the body in
your urine. Vitamin B12 is the only water-
soluble vitamin that is stored in the liver.
VITAMINS
28. VITAMINS USES
⢠Vitamin A plays an important role in
growth and cell development. It also
promotes healthy skin, hair, nails, gums,
glands, bones and teeth; prevents night
blindness and may help prevent lung
cancer.
⢠Vitamin D aids calcium absorption, and
builds and maintains strong bones and
teeth.
29. ⢠Vitamin E protects fatty acids;
maintains muscles and red blood
cells; and serves as an important
antioxidant.
⢠Vitamin K is an essential vitamin for
your body. Your body needs it for
proper blood clotting.
VITAMINS USES
30. VITAMINS USES
⢠Vitamin C: Strengthens blood
vessel walls; promotes wound
healing and iron absorption;
helps prevent atherosclerosis;
supports immunity; serves as
a key antioxidant.
31. VITAMINS USES
⢠Vitamin B1 is important for
maintaining a healthy metabolism. It
also helps maintain normal digestion,
appetite and proper nerve function.
⢠Vitamin B2 is essential for energy
metabolism. It also aids adrenal
function, supports normal vision and
helps maintain healthy skin.
32. VITAMINS USES
⢠Vitamin B3 is important for the body.
Itâs used to metabolize energy and
promote normal growth. In large
doses, Vitamin B3 can also lower
cholesterol.
⢠Vitamin B5: Aids energy metabolism
and normalizes blood sugar levels.
33. VITAMINS USES
⢠Vitamin B6 is an essential vitamin
for good health. It promotes
protein metabolism, metabolism of
carbohydrates and the release of
energy. It also plays a role in proper
nerve function and the synthesis of
red blood cells.
34. VITAMINS USES
⢠Vitamin B7 (also known as biotin)
is an essential vitamin that plays
an important role in maintaining a
healthy metabolism Biotin is
often used to strengthen hair and
nails, and is also called Vitamin H
(for hair).
35. VITAMINS USES
⢠Vitamin B9: To make DNA, RNA, red
blood cells, and synthesize certain
amino acids. Vitamin B9 is also
important for pregnant women, as it
helps prevent birth defects.
⢠Vitamin B12: To make red blood
cells, DNA, RNA, and myelin for
nerve fibres.

43. ⢠Minerals are inorganic substances required by the
body in small amounts for a variety of functions.
These include the formation of bones and teeth; as
essential constituents of body fluids and tissues; as
components of enzyme systems and for normal
nerve function. Minerals are often absorbed
more efficiently by the body if supplied in foods
rather than as supplements.
MINERAL
S
44. ⢠Some minerals are needed in larger
amounts than others, e.g. calcium,
phosphorus, magnesium, sodium,
potassium and chloride. Others are
required in smaller quantities and are
sometimes called trace minerals, e.g. iron,
zinc, iodine, fluoride, selenium and copper.
Despite being required in smaller
amounts, trace minerals are no less
important than other minerals.
MINERALS
46. MINERALS USES
⢠Calcium is a mineral found in many
foods. Almost all calcium is stored in
bones and teeth to help make and keep
them strong. Your body needs calcium
to help muscles and blood vessels
contract and expand, and to send
messages through the nervous system.
Calcium is also used to help release
hormones and enzymes that affect
47. ⢠Iodine is a mineral found in
some foods. Your body needs
iodine to make thyroid
hormones. These hormones
control your bodyâs metabolism
and other functions. They are
also important for bone and
brain development during
pregnancy and infancy.
MINERALS USES
48. ⢠Iron is a part of hemoglobin, a
protein that transports oxygen
from the lungs to the tissues.
It helps provide oxygen to
muscles. Iron is important for
cell growth, development, and
normal body functions. Iron
MINERALS USES
49. ⢠Magnesium is a mineral naturally present in many
foods, and is added to other food products. It is also
available as a dietary supplement and present in
some medicines. It helps your body regulate muscle
and nerve function, blood sugar levels, and blood
pressure. It also helps your body make protein, bone,
and DNA.
MINERAL
S USES
50. ⢠Phosphorus helps to keep your bones healthy. It
also helps keep blood vessels and muscles working
⢠Potassium is needed for your cells, nerves, and
muscles need to function properly. It helps your body
regulate your blood pressure, heart rhythm and the
water content in cells. It also helps with digestion.
MINERAL
S USES
51. ⢠Selenium needs to stay healthy. It is
important for reproduction, thyroid function,
and DNA production. It also helps protect the
body from damage caused by free radicals
(unstable atoms or molecules that can
damage cells) and infections.
MINERAL
S USES
52. ⢠Table salt is made up of the elements sodium
and chloride - the technical name for salt is
sodium chloride. Your body needs some
sodium to work properly. It helps with the
function of nerves and muscles. It also helps
to keep the right balance of fluids in your
body.
MINERAL
S USES
53. ⢠Zinc, a mineral that people need to stay healthy, is
found in cells throughout the body. It helps the
immune system fight off invading bacteria and
viruses. The body also needs zinc to make proteins
and DNA, the genetic material in all cells. During
pregnancy, infancy, and childhood, the body needs
zinc to grow and develop properly. Zinc also helps
wounds heal and is important for our ability to
taste and smell.
MINERAL
S USES
54. ⢠The main function of fluoride in the
body is in the mineralisation of bones
and teeth. Fluoride also protects the
teeth from dental caries (tooth decay)
and is now routinely added to most
toothpastes.
MINERAL
S USES
55. ⢠Copper is the third most abundant dietary trace
metal after iron and zinc. It is a component of
many enzymes and is needed to produce red and
white blood cells. The body also needs copper to
utilise iron efficiently and it is thought to be
important for infant growth, brain development,
the immune system and for strong bones.
MINERAL
S USES
56. ⢠Manganese is required for bone
formation and for energy metabolism.
It is also a constituent of an
antioxidant enzyme, which helps
prevent free radical-mediated
damage to cells.
MINERAL
S USES
57. ⢠Chromium (III) is the active form of this nutrient
and its main functions appear to be linked with
carbohydrate and lipid metabolism. This form of
chromium is thought to promote the action of
insulin, the hormone which controls glucose levels
in the blood. Subjects with adequate dietary
chromium have improved control over blood
glucose and a better blood lipid profile.

61. FIBER
Fiber is a type of carbohydrate
that the body canât digest.
Though most carbohydrates
are broken down into sugar
molecules, fiber cannot be
broken down into sugar
molecules, and instead it
passes through the body
undigested.
62. Fiber helps regulate the bodyâs use of
sugars, helping to keep hunger and blood
sugar in check.
Children and adults need at least 20 to 30
grams of fiber per day for good health, but
most Americans get only about 15 grams
a day. Great sources are whole fruits and
vegetables, whole grains, and beans.
FIBER
63. Insoluble fiber does not dissolve in water. It is the
bulky fiber that helps to prevent constipation, and is
found in whole grains, wheat cereals, and
vegetables such as carrots, celery, and tomatoes.
Soluble fiber dissolves in water and helps control
blood sugar levels and reduce cholesterol. Good
sources include barley, oatmeal, beans, nuts, and
fruits such as apples, berries, citrus fruits, and
pears.
FIBER
64. ⢠The consumption of soluble fiber has been shown
to protect against heart disease by
reducing cholesterol levels.
⢠The consumption of fiber promotes regular bowel
movements and prevents constipation. It may also
reduce the risk of developing colitis and hemorrhoids.
There is also mixed evidence that consuming fiber might
help reduce the risk of colon cancer.
FIBER
65. ⢠People with diabetes who consume a lot
of fiber tend to need less insulinTrusted
Source than those whose fiber intake is
low. Fiber can help slow the absorption
of sugar, helping to prevent spikes after
meals.
FIBER
66. WATER
To prevent dehydration, you need
to drink adequate amounts of water.
There are many different opinions
on how much water you
should be drinking every day. Health
authorities commonly recommend eight
8-ounce glasses, which equals about 2
liters, or half a gallon. This is called the
8Ă8 rule and is very easy to remember.
67. â˘It lubricates the joints
Cartilage, found in joints and the disks of the
spine, contains around 80 percent water. Long-
term dehydration can reduce the joints' shock-
absorbing ability, leading to joint pain.
â˘It delivers oxygen throughout the body
Blood is more than 90 percent water, and
blood carries oxygen to different parts of the body
ADVANTAGES OF DRINKING WATER
68. . It boosts skin health and beauty
With dehydration, the skin can become more
vulnerable to skin disorders and premature
wrinkling
. It cushions the brain, spinal cord, and other
sensitive tissues
Dehydration can affect brain structure and function.
It is also involved in the production of hormones
and neurotransmitters. Prolonged dehydration can
lead to problems with thinking and reasoning.
ADVANTAGES OF DRINKING WATER
69. . It regulates body temperature
Water that is stored in the middle layers of
the skin comes to the skin's surface as
sweat when the body heats up. As it
evaporates, it cools the body. In sport.
â˘It flushes body waste
Water is needed in the processes of
sweating and removal of urine and feces
ADVANTAGES OF DRINKING WATER
70. The digestive system depends on it
The bowel needs water to work properly. Dehydration
can lead to digestive problems, constipation, and an
overly acidic stomach. This increases the risk
of heartburn and stomach ulcers.
. It helps maintain blood pressure
A lack of water can cause blood to become thicker,
increasing blood pressure.
ADVANTAGES OF
DRINKING WATER
71. â˘The airways need it
When dehydrated, airways are restricted by the body in
an effort to minimize water loss. This can
make asthma and allergies worse
. It makes minerals and nutrients accessible
These dissolve in water, which makes it possible for
them to reach different parts of the body
ADVANTAGES OF
DRINKING WATER
72. . It prevents kidney damage
The kidneys regulate fluid in the body. Insufficient water
can lead to kidney stones and other problems
â˘It boosts performance during exercise
Some scientists have proposed that consuming more
water might enhance performance during strenuous
activities dehydration reduces performance in activities
lasting longer than 30 minutes.
ADVANTAGES OF
DRINKING WATER
73. . Weight loss
Water may also help with weight loss, if it is consumed
instead of sweetened juices and sodas. "Preloading"
with water before meals can help prevent overeating by
creating a sense of fullness.
. It reduces the chance of a hangover
When partying, unsweetened soda water with ice and
lemon alternated with alcoholic drinks can help prevent
overconsumption of alcohol
