Why do so many foods have a little transfat

[bigbrain 5]

I'm on a LCHF diet and i noticed a lot cheeses and bacon have a little bit of transfat, something like 0.3g per serving while saturated fat is round 8g. Why do they have any transfat at all ?

Some meat and dairy have small amounts of naturally occurring trans fat. it is not added. The larger amounts in food is from hydrogenated vegetable oil which is added either to keep things solid at room temperature or to give a longer shelf life. The good news is that some companies have taken it out of their products. The louder the voice from consumers the more companies listen.
