Balanced diet
• The food is required by all living organisms, for the following
purposes;
• For energy -- Food is used by the body, as a ſuel to work our
muscles and other body organs.
• • For growth and repair - nutrients present in the food, are
used by the body to make new cells,growth and to replace
damaged cells.
• • To stay healthy - food, is used in the cellular reactions in
our body, to produce energy
. to maintain healthy body, we must eat a healthy and
balanced diet,
• It also means matching the amount of energy (calories)
intake with the amount of energy output, for daily activities
and exercise
• The quantity of food needed, to meet the requirements of
various nutrients, varies with age, gender, physiological
status and physical activities.
Balanced diet
• A balanced diet is the food which provides all the
nutrients in required amounts and proper
proportions.
• A balanced diet is defined as the food which provides,
quantitatively and qualitatively, required amounts
and proper proportions of all the nutrients for
maintaining a good health and physiological
efficiency.
ELEMENTS OF BALANCED DIET
• A balanced diet have macro- and micro-nutrients
• Which include:
• Carbohydrates,Proteins,Fat.,Vitamins, Minerals,Water these
nutrients are essential for daily life.
• All these nutrients can be obtained from different food
groups.
FOOD GROUPS
• A food group is a collection of foods that share similar
nutritional properties or biological specifications
• . they provide similar amounts and types of nutrients
• eg nutrients of the milk, yogurt, cheese and alternatives
food group, include calcium and protein,
• the fruit group is a good source of vitamins, especially,
vitamin C.
• balanced diet can be obtained from four basic food groups
•
• .1. Cereals, millets and pulses
• 2. Vegetables and fruits
• 3. Milk and milk products, eggs, meat and fish,
• 4. Oils
• according to their origin
• Plant origin
• Animal origin
• Food groups according to the predominant functions
• according to their predominant functions.
• Body-building foods, e.g. milk, meat, fish, eggs,
• .Energy-giving foods, e.g. cereals, roots and tubers, fats
and oils, etc.,
• .Protective foods, e.g. vegetables, fruits, milk, etc
OTHER FOOD GROUPS
• Instant foods
• Instant foods are those which undergo special processing,
designed to dissolve or to disperse particles, more rapidly in
a liquid e.g. instant noodles, soup powders, cornflakes, etc
•
• high calorie ,high salt content , presence of additives like
monosodium glutamate increases sodium intake from the
food
• Fast foods
• Fast foods are the foods that are already made or
cooked to order, within minutes for consumption,
• noodles, burgers, fried fish, milk shakes, chips, salads,
pizzas, sandwiches,
• . Storage, handling and microbial contaminations
• , calorie dense foods.
• Street foods
• Street foods comprise of a wide range of readyto-eat
foods and beverages, prepared and/or sold by the
vendors and hawkers, on streets and other public
places,
• e.g. idly, wada, dosa, chat items,
• . They may be contaminated with pathogenic
organisms, unless hygienically prepared.
• Junk foods
• Junk (unhealthy) foods are those foods containing little or
no proteins, vitamins and minerals, but are rich in salt,
sugar, fat and energy (empty calories)
• . Some examples are chocolates, artificially-flavored
aerated drinks, potato chips, ice creams, french fries, etc.
• They are not only calorigenic, but also leads to obesity, rise
of low density lipids (LDL or bad cholesterol), and fall of
high density lipids
•Sometimes foods
•Sometimes food, have very little nutritional value
and are often processed and packaged.
• They are high in fat, sugar and salt, should not be
taken by children on a regular basis.
•Examples ,
•Chocolates, and confectionary
•Sweet biscuits, chips and high-fat savoury biscuits

energy drinks, flavoured milk and flavoured mineral
water
DIETARY SUPPLEMENTS
• Dietary supplement is the product that is intended to
supplement the diet.
• These are neither drugs nor food or food additives

• The word supplement, should be clearly stated on the
label.
•ANTIOXIDANTS
• Antioxidants are present in green-leafy vegetables and plant
foods, like papaya, turmeric, palm oil, amla and guava.
•
• The dietary antioxidants include nutrients, such as Bcarotene
(provitamin A), ascorbic acid (vitamin C), tocopherols,
tocotrienols, riboflavin, sulfur-containing amino acids
(cysteine and methionine) and selenium
• Vegetarianism and vegan eating practices
• this means avoiding animal products, such as meat,
poultry and fish.
• some vegetarians eat animal-related products, such
as eggs, milk, cheese and yoghurt.
• vegetarians eat a variety of legumes, nuts, seeds and
grainbased foods, to gain the same nutrients that
meat, poultry and fish provide.
• . It is very difficult to meet children's nutritional needs
with a vegan diet, because the amount of food
needed for sufficient nutrients may be too large for
the child to manage.

•COMPOSITION OF A BALANCED DIET
• • A balanced diet should provide, nearly, 50-60% of
the total required calories from carbohydrates, about
10-15% from proteins and 20-30% from fats
•
•.• a balanced diet should also provide other non-
nutrients, such as dietary fibre, antioxidants and
phytochemicals
•Dietary fibre, includes complex carbohydrates
obtained from whole grains, fruits, vegetables, beans
and legumes. They are low or moderate in calories,
and are devoid of refined grains and sugar.
• Dietary fiber promotes healthy bowel movement
and decreases the risk of chronic diseases, such as
coronary heart disease and diabetes.
• Antioxidants, such as vitamins C and E, beta-
carotene, riboflavin and selenium, protect the body
from free radical damage
•
• . Spices, like turmeric, ginger, garlic, cumin and
cloves, are rich in antioxidants protect against
oxidative damage
DIETARY GUIDELINES FOR INDIANS
• Widespread malnutrition is due to dietary inadequacy and
unhealthy lifestyle.
• factors are poor purchasing , faulty feeding habits, large
family size, frequent infections, poor health care, inadequate
sanitation and low agriculture production.
• longterm solution to the problem of malnutrition is ensuring
availability, accessbility and consumption of adequate
amount of food.
• Dietary guidelines help to achieve the objective of
providing optimal nutrition to the population.
• 1,Eat a variety of foods, to ensure a balanced diet.
• 2. Ensure provision of extra food and health care to
pregnant and lactating women.
• 3. Promote exclusive breastfeeding for 6 months and
encourage breastfeeding until 2 years, or as long as
possible
• .4. Feed home-based semi-solid foods to the infants after 6
months
• .5. Ensure adequate and appropriate diets, for children and
adolescents, both, in health and sickness
• .6. Eat plenty of vegetables and fruits
• .7. Ensure moderate use of edible oils and animal foods, and
use a minimum of ghee butter/vanaspati
• .8. Avoid overeating, to prevent overweight and obesity
• .9. Exercise regularly, and be physically active, to maintain
ideal body weight.
• 10. Restrict salt intake to a minimum.
• 11. Ensure the use of safe and clean foods.
• 12. Adopt the right pre-cooking processes and appropriate
cooking methods.
• 13. Drink plenty of water and take beverages in moderation
• .14. Minimize the use of processed foods rich in salt, sugar
and fat

people, to enable them to be fit and active.
FOOD PYRAMID
• Food pyramid (Food guide pyramid) is a graphic
representation of the number of servings from the
four major food groups, needed daily, to form a
healthful diet.
•The pyramid is divided into four levels of foods,
according to recommended consumption,
•.• At the base, the group of cereals and legumes/
beans, which should be eaten in sufficient quantity.
•Foods in this group are the sources of complex
carbohydrates and vitamins, minerals and fibre
•. Dietary fibre delays and retards absorption of
carbohydrates and fats, and increases the satiety
value.
• Diets rich in fibre also reduce glucose and lipids in
blood, and increase the bulk of the stools.
• •On the second level (going up the pyramid)
• vegetables and fruits
• Vegetables provide vitamins (such as vitamin A,
vitamin C and folate) and the minerals (like iron and
magnesium) and carbohydrates, including fiber.
•the third level, are dairy foods ,meat and meat
alternatives
• meat and meat alternatives e.g. nuts, eggs and legumes),
i.e. foods and oils from the animal sources, which should
be eaten moderately.
• Dairy products provide proteins, vitamins and minerals
• Meat and meat substitutes are good sources of proteins,
Bvitamins, iron and zinc
• combination of cereals, millets and pulses provides most of
the amino acids and provide better quality protein
•
•The upper part of the pyramid contains fat and
sweets
• . the highly processed foods, which should be eaten
sparingly
• .Excess of these substances could lead to obesity, diabetes,
cardiovascular disease and cancer.
Food pyramid
BALANCED DIET FOR INDIANS
• diet must provide adequate calories, proteins and
micronutrients to achieve maximum growth potential.
• appropriate diet during different stages of life is important,
• Breast milk and energy-rich foods for growth and
appropriate milestones.
• Energy-rich body building and protective foods for
growth and development, and to fight infections for
growth spurt, maturation and bone development
•
• .Nutritionally adequate diet, with extra food for child
bearing and rearing for maintaining health, to prevent
diet-related diseases, and to support pregnancy and
lactation.
• .• Nutrients-dense low fat foods for being physically
active and healthy.
• For planning the menu for balanced diets, following points
should be considered:
• 1.) For all nutrients, minimum recommended dietary
allowance must be met
• Energy derived from cereals should not be more than 75
per cent
• include two cereals in one meal, , like rice and wheat, or
millets and rice.
• Whole grain cereals, par-boiled grains give higher
nutritive value
• . Flour should not be sieved, as it reduces bran
content.
• Minimize the use of refined cereals, like white flour
(maida).
• 2. )Variety of foods should be used in the menu. No
single food has all the nutrients.
• , each meal should consist of all the food groups.
• 3.) To improve the protein quality from plant sources,
ratio of proteins from cereal to pulse should be eight
parts of cereals and one part of pulses.
.
• Two to three servings of pulses should be taken every
day. Germinated pulses are more nutritious.
• One egg can be served along with cereals and pulses,
to improve the quality of proteins.
• , one serving of poultry/fish can be included
•4. Choose a diet low in fat, 15-20 percent of the total
calories (energy) should be derived from fat and oils,
and 5 percent from sugar and jaggery.
• It is better to use more than one type of oil.
Combination of oils should be there to have proper
balance of 0-3 and 0-6 fatty acids.avoid Fried food
• 5. Food rich in fiber should be included in the diet. Green-
leafy vegetables should be taken more than one serving
• Five servings of fruits and vegetables should be included
in a day's diet to meet the requirement of antioxidants
•
• ,6. Every meal should contain at least one medium size raw
fruit. Taking juice out of it may cause loss of some
nutrients, like vitamin C
• 7. About two glasses of low-fat milk should be
included. Curd should be consumed to provide
probiotics
• 8. Use salt and sugar in moderation
• 9. Water should be taken in adequate quantity.
• 10. the number of meals should four. For very young
children and patients, number of meals can be more
• 11. One-third of the nutritional requirement of
calories and proteins, should be met by lunch and
dinner.
•12. For quick calculations, food exchange list can be
used. If possible, meals should be planned, at a time,
for several days.
•13. reduce use of processed and ready to eat foods
as it food contains a variety of food additives.
• 14. To children and patients, whose nutritional
requirements are high, supplementary foods can be
given

Dietary fibre delays and retards absorption of carbohydrates and fats, and increases the satiety value.
  • 50.
    • Diets richin fibre also reduce glucose and lipids in blood, and increase the bulk of the stools. • •On the second level (going up the pyramid) • vegetables and fruits • Vegetables provide vitamins (such as vitamin A, vitamin C and folate) and the minerals (like iron and magnesium) and carbohydrates, including fiber.
