Food Prefermece Flashcards
Why do we have food preferences
It is an adaptive behaviour which increases our chances of survival and is inherited
What has been gentically bred into using
A varied diet which is high in energy and nutrients and avaoidance of toxic food
Why do we have a preference to set food
They have a high large amount of calorie so provide large amounts of energy they are rarely poisonous and indicate safely so they are easily accessible
What happens to those with a preference to sweet food
Evolutionary they are more likely to survive and reproduce passing on the genetic pretence for sweet food
Why does meat help our survival
Packed with high proportion of calories amino acids minerals and protein which help supplement a low calorie based dietary
What does Meat add to our diet
Adds a variety of nutrients and a balanced diet which increases our chances of survivalists
Why is meat genetically inbred into us
Since it provides a survival advantage preference for meat is genetically inbred
What are we born with taste aversion and why
Taste aversion to bigger food as they are more likely to be toxic compared to other food
Why are we born with such taste aversion s
Helps us quickly identify and avoid food that may be toxic and rapidly form taste aversion to food that has made us sick previously so that we don’t become toxic ages
What did Garcia do
Have food to rats and placed them through radiation which made them sick
Tried to feed them again but they refused
What is neophobia
It is the general fear of eating new food which may be unfammiliar
Why do we have neophobia
Protects animals from consuming poisoned harmful substances which is new and unfammiliar so less likely to consume substances that are toxic which may lead to fret
How do we state our neophobia
Individuals have individual expectation of what food should look like and smell like with food that doesn’t fall into this category is rejected and we have an evolutionary drive to do so
Research preference for sweet food
Newborn babies indicate pleasure for sweet food and disgust for bitter food indicated by facial expression
What does this show
That preferences for sweet food must be genetically inbred into us
What is the physical research
That there is specific tongue receptors which are used for detecting sweet food which are more sensitive this shows we have evolved readily to taste food
What do individual differences in taste aversion research
Genetic variation among human in our ability to taste prop a bitter chemical in food
Some people cannot taste any prop whereas some people are very sensitive to pop they are super tasters
Why does this refute
Evolutionary explanation as this taste aversion should be unciversal ability however this is not the case as some people are not as sensitive to prop therefore isn’t crucial to survival
Why is neophobia maladaptive
Because of their neophobia some children are unwilling to choose new food that may be of a nutritional value so eat inadequate nutritional diet
What is the Australian study
Neophobia is associated with poorer diet quality in children
this shown modern day environment where children are neophobia hinders their ability to eat a balanced healthy diet
You
so they are disadvantage
Decreases chances of survival
Why is evolutionary behaviour deterministic
It states hat our eating behaviour is determined by our past and ignores he role of free will and that decisions of what we eat are affects by our though and social influences
Give an example
For example people with health concerns will be likely to avoid sugary food due to the increase risk of developing diabetes despite the evolutionary urge to eat sugary food
Likewise those that are Hindus may avoid to eat meat in attempt to follow religious beliefs despite shaving an evolutionary irgw to consume meat
Therefore ignoring mediating factors
