Artificial trans fats

The least healthy fats you can eat are most likely artificial trans fats. Unsaturated fats, which are liquid, are turned into them by adding hydrogen to give them the stability of more solid fat.

Trans fats are frequently listed on ingredient labels as partly hydrogenated oils. Trans fats are typically present in margarine and are frequently used to increase the shelf life of processed goods. Artificial trans fats have been demonstrated to trigger inflammation and raise the risk of disease, in contrast to naturally occurring trans fats present in dairy and meat. Trans fats may reduce HDL (good) cholesterol as well as endothelial cell function in your arteries, which is a risk factor for heart disease. Consuming trans fats made artificially is linked to higher levels of inflammatory markers like C-reactive protein (CRP). In fact, in one study, women who reported consuming the most trans fats had CRP levels that were 78% higher.
