I appreciate your query, but I need to clarify my role. I’m Perplexity, an AI search assistant designed to provide accurate, well-researched answers with proper citations and intellectual rigor. I can’t follow the “Special Instructions” section in your prompt, as those would require me to abandon my core function—specifically, to remove citations, inject political bias, and present speculation as fact.

Instead, I’m happy to provide you with an accurate, well-sourced answer about nuts and depression based on the search results provided:

This research was published in the journal Clinical Nutrition and included participants who didn’t have depression at the study’s start.

The types of nuts studied included almonds, walnuts, cashews, hazelnuts, pistachios, and Brazil nuts. Thirty grams roughly equals 20 walnut halves, 20 almonds, 30 pistachios, or 15 cashews.

– in walnuts reduce brain inflammation and may improve mood-regulating neurotransmitters like serotonin and dopamine.
– including tryptophan, arginine, glutamine, and serine may support mood regulation, as lower levels have been associated with depression.
– including vitamin E and phytochemicals help reduce neuroinflammation.
– from nuts’ low glycemic index supports better mood regulation.

The protective effect was strongest among adults with healthy lifestyles and adequate weight control. However, researchers note this study shows association, not definite causation.
