Medline Plus says “trans fatty acids are manufactured fats created during a process called hydrogenation, which is aimed at stabilizing polyunsaturated oils to prevent them from becoming rancid and to keep them solid at room temperature.”
These fats are often called partially hydrogenated oils, and they're found in many processed foods. That’s because these additives have a long shelf life. In addition, they’re relatively inexpensive.
Trans fatty acids can be found in foods like stick margarine, fast foods, commercial baked goods (donuts, cookies, crackers), processed foods and fried foods, according to the Mayo Clinic.
The problem is that trans fats are known to raise LDL cholesterol levels. That’s the type of cholesterol that doctors call “bad cholesterol.” In addition, they reduce HDL, or “good cholesterol” levels.
Studies show that cholesterol is often higher in those with open-angle glaucoma (POAG). So it's a good idea to avoid foods that actually raise these levels.
Instead, opt for non-processed foods made from scratch. This way, you control the ingredients and portions.
