Are made when manufacturers add hydrogen to vegetable oil?

When manufacturers add hydrogen to vegetable oil, they create hydrogenated oils. This process, known as hydrogenation, solidifies the oil and increases its shelf life, making it suitable for various food products. However, it can also lead to the formation of trans fats, which are associated with health risks such as Heart disease. As a result, many food manufacturers are now seeking to reduce or eliminate trans fats in their products.
