>> The move from saturated fats (e.g. butter, beef tallow) to trans fats (e.g. margarine) was not necessarily a good one. Sometimes I wonder if most nutritional advice just follows constantly changing fads... The reason for change is often forgotten or even misunderstood. From what I've read there is nothing wrong with eating saturated far or unsaturated fat, but transfat (a.k.a. partially hydrogenated) is very bad for you, as it chokes the machinery for "consuming" one or the other by being a bit of both. After the crusade against fat, people also seemed to get the idea that eating fat makes you fat (the original reasoning had more to do with heart disease), but keto and low-carb diets that work would beg to differ. You gotta read the actual results to get to the bottom of things.
