Trans Fat is made when manufacturers add hydrogen to vegetable oil, a process called hydrogenation. Hydrogenation tends to increase the shelf life and flavour consistency of foods containing these fats.
Old Dutch Foods does not use hydrogenated oils in the manufacturing of Potato Chips and Corn Tortillas. By using natural vegetable oil, Old Dutch Foods manufactures products that have 0 Trans Fats and are low in Saturated Fatty Acids.
Saturated Fatty Acids are not necessarily 'bad' fats. Unless they are consumed in excessive amounts, they are relatively neutral to your body's health. Old Dutch is a responsible snack manufacturer and recommends watching your overall fat intake (including Saturated Fatty Acids) and staying active.
