Artificial trans fats

Trans fat is considered the worst type of fat to eat. Unlike other dietary fats, trans fats — also called trans-fatty acids — raise "bad" cholesterol and also lowers "good" cholesterol.

Hydrogen is pumped into unsaturated oils, such as soybean and corn oils, to turn them into solid fats, which is how artificial trans fats are made. They used to be included in a wide variety of processed foods, including margarine, snacks, and packaged baked products. However, studies on both humans and animals have consistently shown that consuming trans fats causes inflammation and has an impact on heart health. As a result, manufactured trans fats are fully prohibited in the US as of January 2020. Natural trans fats are sometimes found in foods made from animals, but they don't have the same health dangers as trans fats that are made artificially.
