Can ultraprocessed foods meet the same benchmarks for addictive substance as tobacco & alcohol?

Prof Ashley Gearhardt, developer of the Yale Food Addiction Scale on the remarkable similarities. 'They are consumed compulsively, are highly reinforcing, & impact the reward centres of the brain.'

'We're seeing those same behavioural indicators of addiction - the loss of control & the intense cravings. The inability to cut down, even if you know you have a life-threatening illness.'

Ashley N. Gearhardt, Ph.D. Professor of psychology, University of Michigan, (PhD Yale).

Dissertation: An Examination of the Validity of “Food Addiction”.

While working on her doctorate in clinical psychology at Yale University, Dr. Gearhardt became interested in the possibility that certain foods may be capable of triggering an addictive process. To explore this further, she developed the Yale Food Addiction Scale (YFAS) to operationalize addictive eating behaviors, which has been linked with more frequent binge eating episodes, an increased prevalence of obesity and patterns of neural activation implicated in other addictive behaviors. - https://lsa.umich.edu/psych/people/faculty/agearhar.html

The YFAS has been cited over 1,000 times (2024).

This discussion (also on Spotify @PSGRNZ ) traverses:

  • scientific controversy about whether highly processed foods are truly capable of triggering an addictive response

  • Relationship between ultraprocessed foods (UHPs) and food addiction

  • Formalising a diagnostic criteria food addiction – no valid biomarker – behavioural indicators.

'Addiction epidemics often occur because a novel and potent addictive substance is created, but it's addictive potential is undetected or underestimated.'

Our hunger & our satiety signals are very intertwined with our reward & motivation systems.

Science, stewardship & scalability.
Doctors & scientists talking about how policy-makers steward tech, pollution & open-ended systems to protect human & environmental health. Discussions traverse health, environment, agriculture, technology and governance. They shed light on why linear, technical approaches to risk assessment & regulation often create more problems in open-ended, biologically complex environments than they solve.
How can we identify & prevent tipping points to build resilience & protect health – from soil biology; to water systems; to our children and young people - who are being diagnosed with preventable conditions, at younger and younger ages?
Importantly: When policy and decisions around new laws rest upon science claims, how do 'we' create governance structures to prioritise the independent science & research that might inform policy & triangulate industry claims?
There's lots to talk about!
