- Attitudes of Eating Behaviour 2
- Mood and Food
- Biological reasons
- Serotonin hypthosesis
- Carbohydrates such as chocolate contain tyrptophan which is used in the brain to make the neurotransmitter serotonin
- So eating sweet things makes people's mood more positive
- This is unlikely as pure carbohydrate is needed - which is very rare
- So eating sweet things makes people's mood more positive
- Carbohydrates such as chocolate contain tyrptophan which is used in the brain to make the neurotransmitter serotonin
- Opiate hypothesis
- In the brain are opiate neurotransmitters - endorphins.
- They are addictive and lead to feelings of euphoria
- Brain's opiate pathways are part of our reward system which control our feelings of pleasure and reward
- Evidence linked with feeding behaviour: blocking the endorphin brain system using drugs reduces food intake and reduced thoughts about food
- They are addictive and lead to feelings of euphoria
- In the brain are opiate neurotransmitters - endorphins.

- Serotonin hypthosesis
- Biological reasons
- food cravings; reflect need for variety in our diets
- Women more than men, often during pre-menstrual phase or during pregnance
- Affective states are different moods
- Garg et al
- how moods influence food consumption
- People consider pleasurable products (chocolate/popcorn) as mood up-lifting then over-consume them
- Aim: to examine how manipulating happiness and sadness through the content of a film can influence the consumption of hedonistic foods such as buttered popcorn
- Participants watched full length movies that evoked positive/negative effects
- Were told that researchers would be asking them to evaluate the films
- Lack of informed consent
- Sad film: Love Story. Happy film: Sweet Home Alabama
- Matched on several key variables such as running time, quality and box office success
- 5-8 P's watched the movie together and given equal amounts of popcorn and calorie free drinks.
- Rated film as happy or sad and had to say why
- Popcorn container weighed and amount consumed calculated
- Movies were successful in manipulating the desired emotions. Also P’s consumed significantly more (28% more) while watching the sad film than while watching the happy movie
- The more unhappy you are, the more you will eat. The happier you are, you don't need to eat as much (you are trying to activiate the opiate pathway
- Movies were successful in manipulating the desired emotions. Also P’s consumed significantly more (28% more) while watching the sad film than while watching the happy movie
- Were told that researchers would be asking them to evaluate the films
- High internal validity
- Garg et al
- Mood and Food
- Evaluation
- Gender bias, mostly carried out on females
- Focus on nurture
- Determinist
- Mood and Food
