  • 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
        • 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
    • Comfort food

                • Evidence linked with feeding behaviour: blocking the endorphin brain system using drugs reduces food intake and reduced thoughts about food
      • 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
          • High internal validity
    • Evaluation
      • Gender bias, mostly carried out on females
      • Focus on nurture
      • Determinist
