25
the _________ is the link between the consumer subsystem and the nutrition subsystem

26
this subsystem focuses on obtaining nutrients and avoiding contaminants, this also uses physiological indicators as measures of biological functioning.
nutrition subsystem
27
nutrition subsystem foods enter the gastrointestinal tract to be broken down into nutrients
digestion
28
nutrition subsystem after the food is absorbed, it goes to specific sites in the body

involves all the food choices made by consumer at different levels (e.g., household or individual)
consumer behavior
44
inter-disciplinary science that examines all components of the food chain and evaluates their effects from four main points of view (??)

health
46
nutrition ecology this dimension refers to the aspect of nutrition that are associated with the natural basis of human life

define food security
all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food which meets their dietary needs and food preferences for an active and healthy life
52
define nutrition security

agriculture
55
contribs of agri to society
-provision of food -income and employment -labor for the non-agri sector -capital for the development of non-agri sector
56
4 determinants of FNS
1-availability 2-access 3-utilization 4-stability
57
factors affecting the determinants
on crops -agri methods -cropping patterns -land quality and soil fertility on livestock -diseases and parasites -nutritional influences on fisheries and aquaculture -off-farm externalities -weak resources tenure rights -econ constraints for value-chain actors -competition of resources and markets cross-cutting factors -storage method -climate -locality -incentives to produce -social roles -income levels
58
2 methods to measure food available for consumption (national and household)
FBS and HCES
59
key tool to understand the status of food availability as it describes all the factors that constitute the total availability of food in an annual basis
FBS
60
FBS is composed of three sets of data which are:
-domestic food supply -domestic food utilization -per capita food supply
61
domestic food utilization distinguishes how food supplies are used - classifications (6)
1- exported 2- fed to livestock 3- used for seeds 4- processed 5- lost 6- for consumption
62
FBS describes all the factors that constitute the total availability of food in a country over a selected _______-month period.
12 or twelve
63
the difference between the consumption requirements and the estimated food available for human consumption
food gap or deficit
64
concepts encountered in the FBS
1- commodity coverage 2- supply and utilization elements -production -changes in stocks -gross imports -supply -gross exports -feed -seed -food manufacture -waste -other uses -food -per caput supply
65
per caput supply is measured in terms of
1- quantity 2- caloric value 3- protein 4- fat content
66
food production systems
based on food value chain -traditional -mixed -modern livestock -smallholder mixed farming -pastoral systems -commercial grazing system -intensive livestock systems crops -slash and burn -monocropping -multi-cropping -integrated farming
67
harvested commodities that remain to be biologically active even after harvest
fresh produce
68
attributes that irreversibly change after harvest
-flavor -aroma -color -nutritive value -wholesomeness
69

71
primary processing procedures that start from harvest and end before secondary food processing or consumption.
post-harvest operations
72
post-harvest handling acts
-reduce metabolic rates -reduce water loss -minimize bruising -reduce spoilage -prevent freezing injury
73
post-harvest acts that influence food availability for human consumption
