I do think until "science" can come up with conclusive evidence one way or the other — and particularly given the wide variety in individuals' biological/metabolic systems, the best approach is simply to listen to one's own body.

Mine says "ergh, no thanks" to linseed meal (on several occasions), but "hey, that's ok" to linseed. Ergo, that's probably a reasonable point.

It's definitely smart to reproduce the experiments several times — and adjust for externals factors (eg, do it repeatedly over a period of days/weeks, while keeping the rest of your diet reasonably static), but ultimately, you're the person responsible for (and living with) your own health, so who better to listen to?

Ok, I'll admit I have no evidence or knowledge of how it treats horses though, and they do have a large caecum which humans don't.

1. I started the hunt because when I was having linseed meal it made me feel a bit 'off' (which I don't in the slightest when having linseed itself), and

2. Horses are much bigger than fish.. and people.. so it may be messing with them too, just not to a significantly noticeable degree.

Also — wasn't it the flatworm that we're 99% genetically similar to? You can draw some very disturbing conclusions if you start down that line of reasoning.. :)

(Which is not to say *all* horse food, of course; given there are all sorts of valid human-food that horses eat. Like carrots.. and apples..)
