How does cis differ from trans fat?
Cis fats are the typical form of unsaturated fat found in nature, while trans fats are made through hydrogenation. Cis fats have a different shape, so the physical properties are different. Trans fats are even more unhealthy than saturated fats in that they raise your LDL levels and lower your HDL levels.
Is cis healthier than trans?
While cis fats are beneficial and can promote good cholesterol, trans fats are considered harmful to cardiovascular health, especially those trans fats which come from unnatural sources (e.g., hydrogenated oils in processed foods). …
What are trans fats and why are they controversial?

Why was trans fat banned?
In 2015, the FDA deemed artificial trans fats unsafe because of their link to heart attacks. Companies had until June 18, 2018 to eliminate the ingredient from foods.
Why is trans fat worse than cis fat?
The structure of the atoms and molecules can vary slightly, which changes how the fats affect your body. This change may seem small, but it totally changes the fat’s physical properties–trans fats have a higher melting point than cis fats and can stack on top of each other, which makes them solid at room temperature.
Are trans fats worse than saturated fats?
“Trans fats raise (bad) LDL cholesterol levels slightly less than do saturated fats,” says Lichtenstein. “But saturated fats also raise levels of high density lipoprotein (HDL) or “good” cholesterol, and trans fatty acids don’t.” Trans fats may actually lower HDL. Thus, some researchers say trans fats are worse.
Why is trans fat worse than cis?
Why are trans fats bad for you compared to cis fats?

They not only increase low-density lipoprotein cholesterol but also decrease high-density lipoprotein cholesterol, thus increasing the risk of cardiovascular disease. Trans fats provide no benefits to human health and are not essential.
