PSYC 314 WEEK 3
-
FATS
trans fat -- linked to higher risk of heart disease BUT current evidence does not support lo consumption of total sat. fats
diabetes, heart disease, obesity went up???
social engineering went wrong -- changing social environment to support health behaviours -- like seatbelt laws, sugar tax
FAT + MENTAL HEALTH
- omega-3 fatty acids -- play a role in preventing mood disorders, alzheimer's
- fat rich diet (short term) decreases anxiety response in adult male rats
- high fat diet in mice alters gut microbiome, increases suspectibility to mental illness
PROTEINS
-
PROTEIN + MENTAL HEALTH
amino acids needed to manufacture NTs involved in cog. func, mood
high ratio of protein to carbs associated w/ reduced testosterone, increased cortisol in men
high protein/high carb diet found to produce increased stress, anxiety, depression
CARBS
low carb diet -- lower levels of serotonin, NT for happiness
-
-
GMOs/ORGANICS
WHY
- personal values/ethics
- pos. attitude towards organic foods -- subjective norms + perceived control regarding organics/non -GMOs
- better nutritional evaluation -- eg. lower calories, higher willingness to pay
the LESS NATURAL, the less a participant trusts to eat it
the MORE NECESSARY a food item is to dietary needs, more likely to endorse it
- ORGANICS -- no sig. diff in nutritional value, but neg impact of trace pesticide on fetal health, the brain, IQ
- GMOs -- concluded GMOs are safe to eat
PSYCHOLOGY OF NUTRITION -- don't forget abt factors like food-related guilt, eating disorders, etc
-
