A family friend who's a psychiatrist told us that tofu can worsen depression. I'm skeptical, but a web search revealed the following:

Even though soy is packed with lean protein, it's also packed with trypsin and protease inhibitors—enzymes that make the digestion of protein incredibly difficult. Soy is also high in copper, a mineral linked to anxious behavior, and loaded with oligosaccharides, which are known to cause flatulence. (Link, TW: meat)

The article also says tempeh is better than tofu in this regard, so that's good since I like tempeh more than tofu (harder to source though). I wanted to ask here who are more along in life.
