In June 2015, the U.S. Food and Drug Administration (FDA) announced its position that partially hydrogenated oils, the main source of artificial trans fat in processed foods, aren’t “generally recognized as safe” to eat. 3. Fats are compounds that play essential roles in many aspects of human health. Saturated fats cause a build up of LDL cholesterol in the blood stream, which blocks the arteries and leads to an INCREASED chance of developing atherosclerosis and other coronary heart diseases.
