The study of food in relation to health.
NUTRITION
the science of food (nutrients and other substances) action, interaction and balance in relation to health and diseases
NUTRITION
• any substance, organic or inorganic
FOOD
• nourishes the body
• builds and repairs tissues
FOOD
• supplies heat and energy
• regulates bodily processes.
FOOD
A chemical component needed by the body
• to provide energy
• to build and repair tissues
• to regulate life processes
NUTRIENT
• A condition of the body resulting from the utilization of essential nutrients.
NUTRITIONAL STATUS
• Body has adequate supply of essential nutrients efficiently utilized growth and good health are maintained at the highest possible level.
OPTIMUM OR GOOD NUTRITION
• Condition of the body resulting from lack of one or more essential nutrients (nutritional deficiency)
MALNUTRITION
• May be due to an excessive nutrient supply to the point of creating toxic or harmful effects
overnutrition and hypervitaminosis
• the under consumption of energy or nutrients based on RDA and DRI values.
UNDERNUTRITION
• consumption of too many nutrients and too many energy compared w/ DRI levels
OVERNUTRITION
TRUE OR FALSE
The study of food & nutrition is “a science and an art”
TRUE
TRUE OR FALSE:
Essential nutrients are needed throughout life; only the amounts of nutrients needed change.
TRUE
TRUE OR FALSE:
No single food contains all the essential nutrients in amounts needed for optimum health.
TRUE
What is good nutrition essential for? (give atleast 3)
• Growth
• Normal organ development and functioning
• Normal reproduction
• Maintenance and replacement of worn-out cells and tissues
• Optimum activity level and working efficiency
• Resistance to infection and disease
• The ability to repair bodily damage and injury
TRUE OR FALSE:
Eating means that all the essential nutrients are supplied and utilized in adequate balance to maintain optimal health and well- being.
FALSE: PROPER NUTRITION means that all the essential nutrients are supplied and utilized in adequate balance to maintain optimal health and well- being.
