Do Processed Foods Hijack Reward Pathways?

Ultra-processed foods (UPFs) May Trigger Responses Like Substance Use Disorders

Some research I read recently highlighted the importance of eating properly, food noise, and how it relates to addictive behaviour.

It is something I see evidence of all the time in my clinic.

Food Choices Matter

What's important is the food choices we make.

The more wisely we choose, the more our brain chemistry and our body's metabolism recognises that, and allows us to choose wisely again.

What we didn't know until very recently is this: if we choose unwisely, it locks out the part of the brain that wants to choose wisely.

So the more we choose ultra-processed, hyper-palatable foods - those foods that are creating neurobiological pathways - they actually lock out focus.

The effect is likened in some ways to substance dependance.

Can Things Change?

So how can you make the changes necessary to prevent or reverse this process.

We can't deny that making the switch is difficult, but our patients our doing it.

• That's why medications can help.
• Talking to the dietitian helps.
• Talking to the psychologist helps.
• Regular check-ins help.
• Dr Lockie Support can help
