Plant based diets
Environmental considerations
Transport vs heated greenhouses in UK
Asparagus highest environmental impact of veg
Red meat bigger impact than fish, poultry and pork
Environmental impacts of plant based diet depends on where food comes from, water usage, packaging, household preparation, and waste along supply chain
Higher impact if coming from a water stressed country
Green/blue/grey water footprint
Nutritional considerations
Vegan diets lower in protein, vitamins B2, B3, B12, D, iodine, zinc, calcium, potassium, and selenium
No differences in fat intake
Low glycemic load
Diversity of vegan products improved
Famous vegans will just have diet carefully planned out
Risk of potential dietary deficiencies but not certain
Ethical considerations
Vegans try not to causes cruelty to animals in all lifestyle
Boycotting animal products to try to change legislation on animal treatment or greenhouse gas emissions
But just individual consumer purchases may not be enough to achieve this
Factory animal farming also indirectly affects humans rights e.g. food, water, health
Population turning vegan will make it easier to overcome world hunger
Do animals deserve moral consideration?
No suffering to animals without good reason- humans do not need to eat animal products
Health considerations
Significant reduced levels of BMI, total cholesterol, LDL-cholesterol, glucose compared to omnivores
Significant reduced risk of mortality from ischemic heart disease, total cancer
No differnce in total cardiovascular diseases, all-cause mortality and mortality from cancer
Maybe higher risk of impaired bone health due to less calcium
Defining diets
Many types e.g. flexitarian, pescatarian, vegan
Influenced by upbringing and culture
Google hits for vegan increasing
Affordability considerations
Preconception that being vegan more expensive
Found to be cheaper in middle-to high income countries, but more expensive in low income countries
Reductions in food waste reduces household and company costs
