Nutrition is the study of nutrients in food, how the body uses them, and the relationship between diet, health, and disease.
Nutritionists use ideas from molecular biology, biochemistry, and genetics to understand how nutrients affect the human body.
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.

2137ad Merindol Colony Interiors where refugee try to build a seemengly norm...luforfor
This are the interiors of the Merindol Colony in 2137ad after the Climate Change Collapse and the Apocalipse Wars. Merindol is a small Colony in the Italian Alps where there are around 4000 humans. The Colony values mainly around meritocracy and selection by effort.
2137ad - Characters that live in Merindol and are at the center of main storiesluforfor
Kurgan is a russian expatriate that is secretly in love with Sonia Contado. Henry is a british soldier that took refuge in Merindol Colony in 2137ad. He is the lover of Sonia Contado.
Hadj Ounis's most notable work is his sculpture titled "Metamorphosis." This piece showcases Ounis's mastery of form and texture, as he seamlessly combines metal and wood to create a dynamic and visually striking composition. The juxtaposition of the two materials creates a sense of tension and harmony, inviting viewers to contemplate the relationship between nature and industry.

At the end of lecture students should be able
to:
Define nutrition
Discuss important nutrients
Define balanced diet
Understand importance of balanced diet
Describe dietary reference intake
Identify the energy requirement of body
LEARNING OBJECTIVES
3.
The use of foods by organism is termed
as nutrition
The ability of an organism to use a
particular food material depends upon its
chemical compound composition & upon
the metabolic pathways available to
organism
NUTRITION
4.
The study of food or nutrients regarding:
• Digestion
• Absorption
• Transport
• Excretion
• Utilization by body
It also concerned with the certain social, economic,
cultural and psychological implication of food
NUTRITION
5.
It also covers the aspects of food related to its
preservation, marketing, processing and
distribution
Clinical aspects of nutrition covers the
problems associated to deficiency or excess
of nutrients in the body
NUTRITION
6.
Nutrition can prevent disease
Nutrient deficiency diseases:
scurvy, goiter, rickets
Diseases influenced by nutrition
chronic diseases such as heart disease
Diseases in which nutrition plays a role
rickets, osteoporosis
Why is Nutrition Important?
7.
Chemical substances in food that:
• Provide energy
• Provide materials for building body
parts
• Provide factors to regulate needed
chemical processes in the body
• Functions as anti-oxidants
NUTRIENTS
8.
TYES OF NUTRINTS
MAJOR NUTRIENTS
A) Source of energy
• Carbohydrates
• Proteins
• Lipids
B) As source of essential
biochemical
• Essential amino acids
• Essential fatty acids
MINOR NUTRIENTS
1. Vitamins
2. Minerals
3. Water
4. Fiber
9.
1. Carbohydrates : main source of energy
2. Proteins: repair and growth of the body
3. Lipids: provide energy, helps in storing energy and vitamins
4. Vitamins: helps in getting energy from carbohydrates,
proteins and lipids
5. Minerals: regulation of water balance, bone development
and maintenance
6. Water: helps in body processes such as digestion, absorption,
transport and making blood and other body fluid
7. Fiber: regulate intestinal motility, water absorption and
prevent constipation
Biochemical Role Of Nutrients
10.
“Diet that can be followed for a long period of time
& that will keep the body healthy”
It is affected by:
i. Age
ii. Sex
iii. Level of activity
iv. Body surface
v. Climate
vi. Taste and desires
vii. Religious prejudice
viii.Social outcomes
BALANCED DIET
12.
A person must have all these otherwise a
person will feel very tired and will not have
high or enough energy
If you take too much energy containing foods
you will become over weight which leads to
different diseases
BALANCED DIET
13.
The balanced diet should provide the adult
weight 70 kg; with 2400 to 3000 calories per
day
• 1 gm of carbohydrate provide 4.6 k Calories
• 1 gm of fat provides 9.1 k calories
• 1 gm of protein provides 4.2 k calories
ENERGETICS OF BALANCED
DIET
14.
60-70% of total energy should come from
CHO
20-35% of total energy should come from fats
10-15% of total energy should come from
proteins
According to %
15.
While calculating the energy requirements,
we have to consider the energy required for:
i. Maintenance of basal metabolic rate
ii. Specific dynamic action or thermogenic
effect of food
iii. Extra expenditure for physical activities
Energy Requirement Of A
Normal Person
16.
“The basal metabolic rate (BMR) is the
energy required by an awake individual
during physical, emotional and digestive
rest”.
It is the minimal amount of energy required
to maintain life or sustain vital functions like
working of heart, circulation, brain function,
respiration etc.
BASAL METABOLIC RATE
18.
Also called thermogenic effect of
food
“SDA refers to increased heat
production or increased metabolic
rate following intake of food”
SPECIFIC DYANMIC ACTION
(SDA)
21.
“The average daily dietary intake level that is
sufficient to meet the nutrient needs of nearly
all (97-98%) healthy individuals in a group”
Does not include intake of those with any
disease
Must come from consumption of foods
(dietary), does not include intake from
supplement
RECOMMENDED DIETARY
ALLOWANCE (RDA)
22.
“ A value based on observed or experimentally
determined approximations of nutrient intake
by a group (or groups) of healthy people used
when RDA can not be determined”
ADEQUATE INTAKE (AI)
23.
“ A nutrient intake value that is estimated to
meet the requirement of half of the healthy
individuals in a group”
This is restricted to healthy persons only
ESTIMATED AVERAGE REQUIREMENT
(EAR)
24.
“ The highest level of daily nutrient intake
that is likely to pose no risks of adverse health
effects to almost all individuals in the general
population. As the intake increases above the
TUL, the risk of adverse effects increases”
TOLERABLE UPPER LEVEL OF
INTAKE (TUL)
27.
Diet influences certain type of cancers e.g.
Esophagus, stomach, colon, prostate, breast and lung
Consumption of saturated fats associated with
increased risk of cancers especially colon, breast and
prostate
Increase consumption of vitamins like vitamin C
reduced risk of lung, stomach, esophagus and oral
cavity cancer
High fiber diet reduced risk of colon cancer and
diverticulitis
DIET AND CANCER
28.
Group of related disorders that include marasmus,
kwashiorkor, and intermediate states of marasmus-
kwashiorkor.
PEM is due to “food gap” between the intake and
requirement.

surgery
