Investigative journalist Joanna Blythman, author of the brilliant exposé Swallow This, joins us to discuss what’s going on behind the scenes with ingredients in the products we buy in the supermarket. Even healthy-looking products that look like there are no additional ingredients can be a source of chemical contaminants that may be destructive to our health. In this discussion we focus on the gap between regulation and the reality of what you’re getting when you buy both ultra-processed products as well as some goods that might not even look all that “processed”...and we ask the question - how much do you really want to trust your health to a largely self-regulated packaged goods industry?
