SandwichShortOfAPicnic Morning Glory it's all that but worse. To clarify, the term ultra-processed food (UPF) comes from a classification of food in 4 categories, from non-processes to ultra-processed. Most food has some level of processing (fermenting, frying, canning, etc) but the only concern is UPF. And UPF is not just junk food, most foods that claim to be low fat or low sugar are also UPF.
UPF is basically industrially made food that is made to be hyperpalatable and overconsumed. Most of it is full of stabilizers and flavor enhancers and preservatives that you wouldn't find in most other foods.
The classification came from Brazil, when a Brazilian nutritional team spent some years studying what foods people buy in the supermarket, and found that people were buying less sugar but getting heavier, and what had changed was that people were buying more UPF foods.
Once again the "low sugar, low fat" foods were created by big food companies to solve an issue they created themselves, by introducing foods that were high and sugar and fat in the first place...when nature is already full of foods that are low in fat and low in sugar.
There's a ton of shocking things in the book, like that a lot of food companies fund research on healthy eating, how NestlƩ managed to bring obesity and diabetes to Amazon villages by creating a
"floating" supermarket that basically sold junk food, how Coca-Cola funded most of the studies that say exercise makes you lose weight, how some researchers who did studies about UPF failed to disclose they were affiliated with food companies, how
big food companies lobbied that baby formula is better than breastfeeding effectively leading to a rise in infant malnutrition especially in poorer countries where people could barely afford baby formula and didn't have access to clean water...
For me the bottom line is that big food companies need to make money so they make food that is specifically designed to be overconsumed...and that is fundamentally against the principle of sponsoring a healthy, nutritious diet.
