You listen to science and not to crackpots who pretend to do science. Note that most advice regarding nutrition appearing in newspapers/blogs is total crap (as opposed to science).

If you can't distinguish science from crap (or can't be bothered to search for science) I would suggest you go with what seems reasonable to yourself.

That's the whole point though - science so far can't give much useful advice on what to eat, the topic is just too complex.

Science can give hedged explanations of what's been observed in relation to a particular nutrient, but that's a far shot from dietary advice.

What seems to end up happening is "we've observed a correlation between saturated fat consumption and heart disease" makes it out of the science world and gets turned into "avoid saturated fat at all costs" (and buy our replacement products). Then years later we realize it's a lot more complicated than that.

It was known at the time that correlation is not causation. That is a classic example of taking dietary advice from the incompetent.
