Yes, transfats were banned about 3 years. I think most margarine makers took them out voluntarily before that. So yes, margarine is now healthier than butter.I never buy margarine. Originally it was sold as a healthier/less expensive alternative to butter. However, then it was recognized that trans fats in margarine are more of a health concern then the cholesterol in butter. Not sure if the formula for margarine has changed over the years. For baking, margarine and butter behave differently, so I avoid recipes that make it sound like you can use them interchangeably and still get the same results.
I saw a study that many baby boomers didn't like the taste of butter, because they all grew up with margarine.I grew up margarine only never tasted butter until I was adult
I’m getting into these farm butters now and love them so I’m moving into butter only camp these days !!
