I kept reading this second paragraph trying to understand the &amp;quot;without correlations&amp;quot; part. And also the  negative correlations part. And then the full-text has this, which helped I think:&lt;p&gt;&lt;pre&gt;&lt;code&gt;   &amp;quot;Furthermore, total calories and fiber had a negative correlation with gut microbiome diversity, and anxiety and depression decrease as the gut diversity increases.&amp;quot;&lt;/code&gt;&lt;/pre&gt;</text></item></parent_chain><comment><author>snapcaster</author><text>What a weird hill to die on. I think you might be reading more &amp;quot;woo&amp;quot; into the comment you&amp;#x27;re responding to than is necessary. It&amp;#x27;s fine if you keep eating your microwaveable factory slop and keep convincing yourself it&amp;#x27;s identical to cutting a carrot or cooking vegetables but I&amp;#x27;m skeptical you&amp;#x27;ll convince many people of this</text></comment>

The United Nations published so-called NOVA food classification which divides food into four categories by the amount of processing it received.&lt;p&gt;Category 4 is what OP was talking about. Industrially processed stuff full of preservatives, artificial coloring,  hydrogenated oils, protein isolate, maltodextrin, invert sugar etc. Unlike the other three categories, this sort of industrial processing is a relative newcomer, it wasn&amp;#x27;t even a thing 100 or 150 years ago, so it is entirely plausible that our guts and our gut biome may not be happy about it.</text></comment>
