Featured Expert Contribution: Salt, Processed Food and Metabolic Health

I was recently featured as an expert contributor in an article published by SAVEUR Magazine, the New York-based international food and culture publication, discussing the role of salt in digestion, metabolic health and modern diets.
The piece explored a much wider and more nuanced conversation around sodium than the usual “salt is bad” narrative.
Within the article, I discussed how sodium and chloride are involved in digestive signalling, stomach acid production, bile flow, pancreatic enzyme release and nutrient absorption, alongside the wider relationship between salt, food quality and metabolic health.
One of the key points raised was that context matters.
For individuals consuming highly processed diets dominated by packaged and restaurant foods, excessive sodium intake can absolutely become problematic. However, this is very different from someone eating predominantly whole foods and seasoning meals normally within a nutrient-dense diet.
The article also explored how industrialised food systems changed our relationship with salt, with modern ultra-processed diets now contributing the majority of sodium intake in many populations.
As discussed in the feature, sodium was historically consumed within traditional foods such as broths, fermented foods, cured proteins and meals prepared from minimally processed ingredients, rather than being isolated within heavily manufactured products.
The broader discussion touched on:
salt and digestive physiology
sodium’s role in blood volume and nutrient transport
ultra-processed food consumption
gut health and microbial balance
restaurant and packaged food sodium exposure
why sodium tolerance and requirements may differ between individuals
It was great to contribute to a publication taking a more balanced and physiologically informed approach to the conversation around salt and health.
