Food Sustainability Flashcards
Sustainable Diet Definition
Diets with low environmental impacts, food and nutrition security, protective and respective, and optimizing natural and human resources.
3 Diets to help achieve as Sustainable Diet
- EAT Lancet
- Blue Dot
- NZ Guidelines
EAT Lancet (5)
diet healthy for people and the planet
- change eating habits
- improve food productions
- reduce food waste
plant based diet, restrict meats, mainly wholegrain
Blue Dot
‘the world is just one blue dot’
- decrease meat
- increase plant proteins
- increase wholegrain
- decrease dairy
found that lots of people had the intention to eat more sustainably but way less actually did.
NZ Guidleines
includes thing about eating sustainably
Climate Change
2002 NZ committed to the international treaty that commits to reducing greenhouse gas emissions
Decrease Earths Temp By
1.5 degrees by 2050
6 Type of green house gasses in Order of amount
Agricultural
Energy
Processes and product use
Water
Tokelau
and Land use and forestry (but this takes away CO2)
Agriculture Sector on Climate Change
Dairy Industry and fertiliser the biggest impacts
1990-2022 emission from Agriculture increased by
12%
Impact of Food on Carbon Emissions
1/4 from food
1/2 of all food from animal products
1/2 of all animal products emissions come from beef and lamb
Life Cycle Assesment
everything into it and everything out of it
In sheep farms where does the most of the emissions come from % in the process of lambs
80% actually farming the sheep whilst on the farm
Cheese most emissions come from
In the Vat (on the farm)
GHG emissions of Beef
30
GHG emissions of Pork
5-6
GHG emissions of Chicken
3
GHG emissions of Plant foods
less than 1
Why do Animals have such high GHG
they go through 2 systems
1. plants and grass
2. animals eat this grass and of the animals 45% is what humans eat and the other 55% is ‘waste’ in NZ. hence so high as over half of the animals is waste, compared to vege in which you eat must a of carrot for example
Setting the Table
Level One: large and most significant and immediate
3 Ways to make our Diets more Sustainable
- reduce consumption of meat and dairy
- reduce consuming foods with low nutritional value
- reduce food waste
Global Estimate of food loss and waste
30-40%
Measuring Food Waste in NZ
12.3 = #SDG12
12.3.1 = food loss (manufactures and producers)
12.3.2 = food waste (consumer waste)

Disposal
NZ Top Wasted Food
Bread
In Restaurants what % of foods is wasted
33%
Supermarket Waste
most goes to pig farmers
Household Waste
10 x more waste than supermarkets
NZ Food Lost and Weight %
10-20% less than global as we are a well developed country
2 Ways to Reduce Waste in NZ
- Transport surplus food around NZ
- Upcycling
SDG and Indigenous People
need to incorporate these people are they are the furtherest behind
Amount of Land and Population of Indigenous People
1/4 of land
5% of Population
Food Security
the availability of people to acquire appropriate and nutritious foods on a regular and reliable basis for a active and healthy life
Food Sovereignty
it is the right of people to eat healthy and culturally appropriate food produced through sustainable methods and their right to define their own food and agriculture systems
% of NZ that are Pacific and their capital of the world
8% and Auckland
Pacific Food Insecurity
long term effects on education, mental/physical health, financial strain and increase crimes committed
Pacific’s People Food Influences (4)
- cost
- availability
- culture
- quality and quantity
SPEECH Factors and Pacific People
Social
Political - promoting of unhealthy foods
Economic - fast foods are cheaper than healthy foods
Environmental - increase demand for pacific foods
Cultural - eat until your full
Health - fas food is normalised
Pacific - Recommendations to improve their food Culture (3)
- Quality time is needed for quality food instead of quantity.
- Pacific families growing food on their land
- Lower costs of healthy foods
