TFA contributes to the risk of heart attack and diabetes, and increases the chance of stroke. They cause cholesterol to rise in the body.
The use of TFA (especially hydrogenated oils) raises low-density lipoprotein cholesterol levels. Low-density lipoprotein cholesterol is the “bad” cholesterol. It damages the heart and blood vessels. It should be present in the blood as little as possible (Foods High in Trans Fat, 2020).
TFA are sometimes referred to as “fat killers”, because they stimulate metabolic oxidation processes, further narrow blood vessels, and increase the risk of various cancers (Daily Newspaper “Klaipėda,” 2018).
