But surely the Sunflower oil is a liquid, so it has to be partially hydrogenated in order to make it spreadable rather than pourable?
And isn't it the hydrogenation that makes these foods much more harmful?
That was my understanding anyway...
No "modern" margarine (pronounced with a "hard" g if you're in the business) has high levels of trans fats any more (at least those sold in Europe), so not harmful in that way.
Oh, and they aren't all from veg oils - some of them are made with hydrogenated fish oils - boy does that stink when they're cleaning out the reception silos or disposing of the Fullers earth filtration medium. And it's not just hydrogenated, it's (sometimes) bleached and deodourised and coloured - no-one like spreading what looks like lard on their sandwiches.
Healthy? Butter is a natural product with (sometimes) salt added as a perservative and maybe some annatto for colour. Margarine was developed to feed the French army on it's march on Moscow under Napoleon. It's ersatz butter. Why eat it? But then again why eat Quorn or TVP?
My tuppence - follow the advice of Egon Ronay - when asked how he managed to stay so slim whilst eating for the various food guides he replied that he ate whatever he wanted, just not very much of it.
