This document discusses nutrition, nutrients, and the relationship between nutrition and health. It provides classifications of foods and nutrients, as well as their functions. The key points are:
1. Food provides energy, growth, development and protects the body from diseases. Nutrition involves ingestion, digestion and absorption of nutrients from food.
2. Nutrients include macronutrients like proteins, carbohydrates, and fats which are needed in large amounts, as well as micronutrients like vitamins and minerals needed in small amounts.
3. A balanced diet includes a variety foods in proper amounts and proportions to meet daily nutrient requirements for health. Good nutrition prevents deficiency and chronic diseases while an unhealthy diet increases
Nutrition is the study of the nutrients in food and how they nourish the body.
Nutrients are components of food that are needed for the body to function
Life cannot be sustained without adequate nourishment.
Man needs adequate food for growth and development and to lead an active and healthy life.
Food plays an important role in maintaining a person's nutritional and health status.
PLANTS
Many plant & plant part are eaten as a food.
Seeds are good source of food for animals including humans because they contain nutrients.
All seeds are not healthy. Eg- apple seeds & cherry seeds contains cyanide.

There are seven main classes of nutrients that the body needs. These are carbohydrates, proteins, fats, vitamins, minerals, fibre and water. It is important that everyone consumes these seven nutrients on a daily basis to help them build their bodies and maintain their health. Deficiencies, excesses and imbalances in diet can produce negative impacts on health, which may lead to diseases.
Macronutrients
“Macro” means large
These are nutrients which people need to eat regularly and in a fairly large amount.
They include carbohydrates, fats, proteins, fibre and water.
These substances are needed for the supply of energy and growth, for metabolism and other body functions.
II. Micronutrients
‘micro’ means small
Micronutrients are substances which people need in their diet in only small amounts.
These include minerals and vitamins.
Most foods are mixtures of nutrients( in 1 food more than 1 nutrient may be present)

Most of the foods we eat, provide several nutrients. So to make a wiser diet plan, it is prudent to select a combination of foods that deliver a full contingent of nutrients for good health. Our major focus should be on selecting foods that will deliver all the essential nutrients without excessive energy intake. Food choices made over years influence the body’s health, and consistently poor choices increase the risks of developing chronic diseases.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2. Food can be defined as anything edible that can be solid, semisolid or liquid
which when swallowed, digested and assimilated in the body, proves useful
to it. These substances not only keep the person alive, but also provide
energy used for growth and development, regulate the body processes and
protect the body from diseases.
NUTRITION & HEALTH
3. Nutrition is defined as the science of foods, nutrients and other substances
they contain; and of their actions within the body including ingestion,
digestion, absorption, metabolism and excretion.
4. Nutrients are organic or inorganic substances present or contained in food
which is required or necessary for growth and maintenance of function of
body.” E.g.: Proteins, Vitamins etc.
Or
Nutrients have been defined as “chemical substances found in food that cannot
be synthesized at all or in sufficient amounts in the body, and are necessary for
life, growth and tissue repair”.
Or
Nutrient “or “food factor” are organic and inorganic complexes contained in
food, which are responsible for the functions of foods and protect the body from
disorders.
5. Balanced Diet A balanced diet is one which includes a variety of foods in
adequate amounts and correct proportions to meet the day’s requirements of
all essential nutrients such as proteins, fats, carbohydrates, vitamins,
minerals, water, and fibre.
6. 1. Food is a basic and foundational part of our lives. Food plays a vital role
for human existence just as the air we breathe and the water we drink.
The food we eat is utilized in the body and assimilated substances are
used for growth and maintenance of the tissue.
2. People who eat right foods rich in nutrients enjoy their lives more, live
longer, and are at a reduced risk of disease.
3. Good nutrition is critical in preventing not only deficiency diseases, but
also chronic diseases. Nutrition is vital to our bodies as water is to plants.
An unhealthy diet increases the risk of many diet related diseases.
THE RELATIONSHIP BETWEEN NUTRITION AND HEALTH
7. Food can be classified in accordance to their chemical property, to
their function, to their essentiality, to their concentration and to their
nutritive value. A classification based on nutrients present will
ensure that all nutrients are made available to the body and offer
greater variety within the group.
There are five basic food groups suggested by the Indian Council
of Medical Research (ICMR). These include:
Cereals, grains and products
Pulses and legumes
Milk and meat products
Fruits and vegetables
Fats and sugars
CLASSIFICATION OF FOOD
8. Cereals, grains and products Pulses and legumes
Milk and meat products Fruits and vegetables
11. a) According to the chemical nature
i. Carbohydrates
ii. Vitamins
iii. Proteins
iv. Dietary Fiber
v. Fats
vi. Water Minerals
12. b) ACCORDING TO THEIR FUNCTION IN THE BODY
Energy giving foods:
• The carbohydrates, fats and the protein are considered as calorie nutrients, so that
the body can perform the necessary functions. Rice, chapatti, bread, potato, sugar,
oil, butter and ghee are examples of energy giving foods.
Body building foods:
• Foods such as proteins, fats and carbohydrates are also called as body-building
food. They are the nutrients that form body tissues. Fish, meat, chicken, eggs,
pulses, nuts and milk are some body building foods.
Protective foods:
• Vitamins and minerals are the nutrients that function to regulate body processes.
They protect us from various diseases. Fruits and vegetables are some examples.
Therefore we must eat these regularly.
13.
14. c) According to its mass depending on the quantity necessary for cells and
organisms are classified as:
1. Macronutrients: Macronutrients are required in large quantities daily.
Proteins, carbohydrates and fats are macronutrients. They are the basis of
any diet.
2. Micronutrients: Micronutrients are needed in small quantities (usually in
amounts less than milligrams). These nutrients are involved in regulating
metabolism and energy processes. They are vitamins and minerals.
18. NUTRIENTS
• The substances which are present in the food and consumed in our body
for its vital functions are called nutrients. According to the World Health
Organization (WHO), these nutrients must come from food, and they are
vital for disease prevention, growth, and good health. There are several
constituents such as:
19. Carbohydrates are the chief sources of energy (Providing 4 Kcals/gm).
Carbohydrates consist of carbon, hydrogen, and oxygen.
The general empirical structure for carbohydrates is (CH2O)n. (1:2:1)
The building blocks of all carbohydrates are simple sugars called
monosaccharide.
Classification of Carbohydrates
• Monosaccharide: these are the simplest form of carbohydrates containing
simple sugar molecule. Example: Glucose, Fructose and Galactose.
• Disaccharide: These carbohydrates composed of two units of
Monosaccharide’s. Example: Sucrose, Lactose and Maltose.
• Polysaccharide: These are the complex sugars containing numerous units of
monosaccharide molecules. Example: Glycogen, Cellulose and Pectins.
Carbohydrates
20. Daily requirements
Carbohydrate intake should be in the range of 300-500gm (50%- 70%) out of the total energy
intake for adults and 40-60% for children.
Sources
All sugars, Jaggery, Honey, Pulses, Whole Grains, Cereals, grains, rice, fruits, milk, yogurt,
beans, roots and tubers such as potatoes, beet root etc.
21. Functions of Carbohydrates
a) Living organisms use carbohydrates as accessible energy to fuel cellular
reactions.
b) They are the most abundant dietary source of energy (4kcal/gram) for all living
beings.
c) Stored carbohydrates act as an energy source instead of proteins.
d) Carbohydrates are intermediates in the biosynthesis of fats and proteins.
e) Carbohydrates aid in the regulation of nerve tissue and is the energy source for
the brain.
f) Formation of the structural framework of RNA and DNA (ribonucleic acid and
deoxyribonucleic acid).
g) They help in the modulation of the immune system.
24. Proteins are the essential constituents of the diet. Proteins are made up of amino
acids. Amino acids are needed for replacement and growth of the body parts.
Amino acids are classified as essential and non essential amino acids. Essential
amino acids cannot be synthesized by the body and must be taken through foods
whereas non essential amino acids can be synthesized by the body.
DAILY REQUIREMENTS
The ICMR recommends 1gm of protein/ Kg of body weight for adults.
The amount of protein should be increased for children, pregnant and lactating
mothers by 1.5- 2.0 g/kg body weight.
II. Proteins
Sources of Protein
25.
26. FUNCTIONS OF PROTEINS
1) Protein helps in synthesis of enzymes, immunoglobulin, plasma proteins and hormones in
the body.
2) Protein helps in growth and repair of body tissues
3) Proteins are secondary sources of energy during deficiency of carbohydrates and fats.
(Provides 4 Kcals/gm).
4) Proteins help in forming haemoglobin.
5) Proteins help in antibody formation.
30. Fat are concentrated sources of energy containing Carbon, hydrogen &
oxygen.
Fat are solid up to 200C and if they are liquid at that temperature they are
called Oils.
Fat are insoluble in water and soluble in Chloroform, petrol and Ether.
Fat is deposited as adipose tissue in the body and perform essential functions
in the body.
Fats are composed of fatty acids and contain oxygen, carbon and hydrogen.
3- Fats
31. CLASSIFICATION
Fats are classified in to:-
1) Simple Lipids (Ex. Triglycerides)
2) Compound lipids (Ex. Phospholipids)
3) Derived lipids (Ex. Cholesterol)
Fats are classified in to two types: Saturated fat and unsaturated fat.
Saturated Fat: These have full number of hydrogen atoms. These are from
animal sources. Example: Butter, Ghee and vegetable oil.
Unsaturated Fat: These contain one, two or more double bonds of fatty
acids. These are extracted from vegetable sources. Example: Groundnut oil,
soyabean oil, sunflower oil.
DAILY REQUIREMENTS
15-20% of total calorie requirements should be from fat. That is about 44 gm
to 77 gm. of fat per day if you eat 2,000 calories a day.
32. Fats are classified in to two types: Saturated fat and unsaturated fat.
Saturated Fat: These have full number of hydrogen atoms. These are from
animal sources. Example: Butter, Ghee and vegetable oil.
Unsaturated Fat: These contain one, two or more double bonds of fatty
acids. These are extracted from vegetable sources. Example: Groundnut oil,
soyabean oil, sunflower oil.
DAILY REQUIREMENTS
15-20% of total calorie requirements should be from fat. That is about 44 gm
to 77 gm. of fat per day if you eat 2,000 calories a day.
33. Supplies energy (9 kcals/ gm).
Improve the palatability of food (flavor and taste)
Supports body organs like liver and kidneys
Provides insulation and thermoregulation against cold
Provides essential fatty acids which helps in growth, promotion and
maintenance of skin integrity.
Helps in formation of hormones in the body.
Helps in transportation of fat soluble vitamins.
FUNCTIONS
36. • Vitamins are organic compounds that people need in small quantities.
Most vitamins need to come from food because the body either does
not produce them or produces very little.
• Different vitamins play different roles in the body, and a person
requires a different amount of each vitamin to stay healthy.
37. FAT SOLUBLE VITAMINS
Vitamin-A
• The chemical name is Retinol.
• Found in foods of both plant and animal origin.
• Function: It is essential for eye health.
Deficiency
Deficiency Syndrome
Decreased resistance to infection
Dry scaly skin
Night blindness (Inability to see in dim light)
Bitot’s spots- Greyish, rough and raised patches on conjunctiva
Keratomalacia- Softening of the cornea.
• Daily requirements: 0.4-1 mg Sources. Green leafy vegetables and
yellow orange fruits and vegetables like mango, papaya, pumpkins
and carrots are good sources of β-carotene.
39. Vitamin-D
Vitamin D is synthesized by sunlight.
Vitamin D is essential for bone growth.
Daily requirements: 400 IU Sources
Generated in the skin by action of ultra violet rays of sunlight
Food sources are milk, butter, cheese, egg, fish and fish liver oils, and foods
which have been fortified by addition of vitamin D.
Functions
Increases intestinal absorption of calcium and phosphates.
Mineralization of bones.
Vitamin D is also essential for the dental health. It prevents tooth
decay and loss, strengthen the gums and reduces risk of any oral
infection.
40.
41. Rickets characterized by reduced
growth and softening of bones. This
disease is generally seen in children
due to lack of vitamin D. Children
develop very thin, deformed bones
Osteomalacia, similar to rickets but is
usually seen in elderly people suffering
from vitamin D deficiency.
This disease reduces the absorption of
calcium in the body leading to soft and
deformed bone structure, bending of the
spinal cord and legs and increased risk
of fractures.
Osteomalacia
Rickets:
42. Osteoporosis, being most common
in elderly where the bone density
reduces, making it more porous in
nature and causing increased risk of
broken bone and fractures.
Osteoporosis
43. Vitamin E
• Vitamin E is an antioxidant and formed up of chemical substance
called Tocopherols.
Daily requirements:
• 15UI per day.
Sources
• Milk, oils, eggs, leafy vegetables, papaya, grains, nuts.
Functions
• Antioxidant (Prevents the formation of oxidative free radical)
• Co factor in electron transport
• Prevents or delays the ageing.
44.
45. Vitamin K
• It is called as Antihemorrhagic vitamin. It is required for the fromation
of Prothrombin in the liver the 2nd factor of coagulation.
• Due to deficiency of Vit. K the prothrombin content in blood may lead
to bleeding disorder.
Daily requirements
• WHO suggested RDA of 55 μg per day for adults.
Sources
• Green leafy vegetables, cereals, fruits.
