This book really clarified for me what specific ingredients in processed foods  (like xanthan gum, polysorbate-80, and carrageenan) were doing to my body. I knew they were "bad" but I didn't know why. They have been found to alter your gut microbiome, cause inflammation, which can increase risk of chronic illnesses. This info isn't widely known because of... capitalism! Large corporations making big money on Ultra Processed Foods don't want you to know how bad these (and many other) ingredients are for your body and for the environment. The corporations themselves can't be trusted to monitor themselves or be trustworthy to create "safe" food, so it's really up to governments to regulate it. It's naive to think that the (processed) food we can buy in a grocery store is safe. It really isn't. (And that is sad!) Conclusion: cut out all the ultra processed food from your diet. Read labels. Don't put anything in your body that has ingredients in it that you can't make in your home kitchen.
