I'd never eat linseed oil. Lookup what it's used for historically, varnishing and what not. That rancidification and cross-linking is something you def don't want happening in your body.
Just because something is used for varnishing doesn't mean it's unhealthy. Can you post any serious and credible source that says linseed oil is unhealthy?
It's trash. Unedible. You know how even in the mainstream, it is common knowledge that burnt oil is bad? Linseed doesn't even need to heat up to start reacting.
