This doesn’t seem to be worded very well:
> greater fat and carbohydrate intake is directly associated with anxiety and depression
Carbohydrate was positively correlated, and fat was negatively correlated with anxiety and depression.

#12I’ll confess that I’ve only read the abstract, but was totally confused by this apparent contradiction…
> We found strong correlations between greater consumption of fat and protein to lower anxiety and depression
vs
> We have shown that changing diet affects mood and happiness, that greater fat and carbohydrate intake is directly associated with anxiety and depression
The first says fat reduces anxiety and depression. The second seems to imply it reduces it- unless “directly associated” actually means “negatively correlated”??
Also, are they saying that increased fiber reduces gut biome diversity?

#13 "After the diet change, we observed significant changes in measures of anxiety, well-being and happiness, and without changes in gut microbiome diversity. We found strong correlations between greater consumption of fat and protein to lower anxiety and depression, while consuming higher percentages of carbohydrates was associated with increased stress, anxiety, and depression."
"We also found strong negative correlations between total calories and total fiber intake with gut microbiome diversity without correlations to measures of mental health, mood or happiness.... inversely correlated with gut microbiome diversity."
"Furthermore, total calories and fiber had a negative correlation with gut microbiome diversity, and anxiety and depression decrease as the gut diversity increases."Re: The Role of Diet on the Gut Microbiome, Mood and Happiness
#14I'm glad to see more studies on this, as it's long been misunderstood how strong of a connection there is between the gut microbiome and mental health. Some go as far to referring to the gut as our second-brain, due to its critical role.
Serotonin (the moood-regulating neurotransmitter), for instance, is produced _primarily_ in the gut (up to 95% of it). https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6469458/#:~:tex....

Fiber reducing biodiversity would be news. I thought consensus was the other way around?
Re: The Role of Diet on the Gut Microbiome, Mood and Happiness
#16Has anyone researched the opposite? Like the role of mood and happiness on the gut microbiome. I was diagnosed with Celiac 5 years ago, could never gain weight and had my share of struggles with anxiety etc. I recently found a counsellor who told me to stop overthinking, seeking knowledge and a few other things which after following I gained 5 kilos and became a happier person. I always thought my gut was to blame bu…
I’m not an expert at all but believe there’s good evidence for a large stress/unhappiness -> cortisol -> significant metabolic changes linkage.

#17Since this study only explored a 2 week change, does anyone have any info on more permanent changes? I’m uninterested in temporarily having less anxiety for 2 weeks. I would like to know what’s my anxiety after 2 years!

The idea that fat and protein are good while carbs are "crap" is controversial.

That's the kind of garbage results you get when you run a study with only 20 participants. Also they changed to both mediterranean and ketogenic? Wtf
Re: The Role of Diet on the Gut Microbiome, Mood and Happiness
#20Interesting. Note this has not yet been peer-reviewed, so findings must be taken with an especially large pinch of salt even compared to your average paper. In this case, they only looked at 20 adults over 2 weeks, so I feel that any conclusions drawn here are circumstancial at best. Apparently the reseach was funded by NIH and therefore at least partly the taxpayer. Seems like a bit of a strange study to fund, in my…
Don't go too heavy on the salt.
