Is the study of food and how the body makes use of it. It deals not only with the quantity and quality of food consumed but also with the process of receiving and utilizing it for the growth and renewal of the body and for the maintenance of the different body functions
Nutrition
Is any substance, organic or inorganic, when ingested or eaten, nourishes the body by building and repairing tissues, supplying heat and energy, and regulating bodily processes
FOOD
Food Qualities
- It is safe to eat.
- It is nourishing or nutritious
- Its palatability factors satisfy the consumer.
- It has satiety value
- It offers variety and planned within the socioeconomic context
- It is free from toxic agents or does not contain substances deemed deleterious to health
Are chemical substances found in food.
Nutrients
Nutrients diverse roles in the body
✓ Providing heat and energy
✓ Build and repair body tissues
✓ Regulate body processes
Classification of Nutrients

Nutrient Classification - ACCORDING TO FUNCTION
- BODY BUILDING nutrients
- REGULATORY nutrients
- Nutrients that FURNISHES ENERGY
Nutrients are either ___ or ___
ORGANIC or INORGANIC
Organic nutrients
protein, fat, carbohydrate, and vitamins
Inorganic compounds
minerals and water
Are organic catalysts that are protein in nature and are produced by living
cells
ENZYMES
composed of the protein part called apoenzyme and a
cofactor
Enzyme System
cofactor is sometimes called
activator or coenzyme
Are organic substances produced by special cells of the body which are discharged into the blood to be circulated and brought to specific organs or tissues that are remote from the source or point of manufacture
HORMONES
a.k.a Nutriture, is the condition of the body resulting from the utilization of essential nutrients
* one may be classified as having good, fair, or poor nutriture depending upon
the primary or secondary factors
NUTRITIONAL STATUS
means that the body has adequate supply of essential nutrients that are efficiently utilized such that growth and good health are maintained at the highest possible level
OPTIMUM or GOOD NUTRITION
Is the opposite of good nutrition, It is a condition of the body resulting from a lack of one or more essential nutrients or it may be due to an excessive nutrient supply to the point of creating toxic or harmful effects
MALNUTRITION
is the structural, functional and biological unit of organism.
CELL
Compositions of Cell (Give atleast 5)
- Nucleus
- Peroxisome
- Endoplasmic reticulum
- Plasma Membrane
- Cytoplasm
- Mitochondria
- Vacuole
- Lysosome
- Golgi Apparatus
- Microfilaments
“The quality and cost materials
at the time of purchase largely
determine the quality and cost of
the finished product.

CLASSIFICATIONS OF NUTRIENTS
MACRONUTRIENTS & MICRONUTRIENTS
THREE MAJOR NUTRIENTS
- CARBOHYDRATES
- PROTEIN
- FATS
major source of energy of the body
CARBOHYDRATES
CLASSIFICATION OF CARBOHYDRATES
- MONOSACCHARIDES
- DISACCHARIDES
- POLYSACCHARIDES
- Simplest form of carbohydrates
- Do not require digestion
MONOSCCHARIDES
It is a process of transforming non-carbohydrate substrates into glucose
GLUCONEOGENESIS
with less available carbs for energy, more fats may be broken down, but not to energy. Fat fragments combine and form ketone bodies
KETOSIS
⮚ made up of 2 monosaccharides
⮚ they are sweet and must be changed to sugars by hydrolysis before they can be absorbed
DISACCHARIDES (double sugar)
⮚ composed of many molecules of simple sugars
⮚ commonly known as complex sugars
POLYSACCHARIDES
