Macro partitioning
Trans fats from partially hydrogenated oils have no safe level of consumption and should be limited as much as possible due to their adverse effects on multiple cardiovascular risk factors.
Avoid trans fats completely. Check food labels for 'partially hydrogenated oils' and avoid products containing them. There is no safe amount of trans fat, and they significantly increase heart disease risk by raising bad cholesterol, lowering good cholesterol, and increasing inflammation.
StrongRefutesVERY_HIGH confidence
The Institute of Medicine determined that there is no safe level of consumption of industrial trans fats from partially hydrogenated oils. Trans fats adversely affect a diverse range of CVD risk factors: they raise LDL-C, raise triglycerides, lower HDL-C, increase inflammation, promote endothelial dysfunction, and may promote hepatic fat synthesis, resulting in far greater risk of developing CHD than any other macronutrient.
Why this rating
Supported by Institute of Medicine determination and multiple studies showing adverse effects on diverse CVD risk factors.
