Why does low cholesterol cause aggression?
There might be a Darwinian explanation. According to Meninger clinic researchers, lower blood LDL cholesterol may be a signal for famine, which led to an adaptation of a response of more aggressive behavior.(1) Of course I think this is a pretty far-reaching hypothesis, but it’s interesting.
