Robert Mayfield, Ph.D ABMPThis study seems to suggest that heavy red meat diets are Major depressive disorder protective, and that diets heavy in non-oily fish may either contribute, or not protect against MDD (somewhat to my dismay) https://pubmed.ncbi.nlm.nih.gov/36162666/ #MedMastondon
Causal influence of dietary habits on the risk of major depressive disorder: A diet-wide Mendelian randomization analysis - PubMed
In this two-sample MR analysis, we observed that higher beef intake may be protective against MDD. However, MDD did not appear to affect dietary habits. Potential mechanisms need to be further investigated to support our novel findings.
