All fats are not the same. There are "good" fats and "bad" fats. When we eat foods high in saturated fat or trans fat, it raises the bad (LDL) cholesterol in our blood. Having high LDL cholesterol increases the risk for heart disease, the leading cause of death in the US, in New York, and in Monroe County. Trans fat is even worse than saturated fat because it actually lowers the good (HDL) cholesterol in the blood. Eating foods high in poly and monounsaturated fat have a good effect on cholesterol levels and are encouraged.
Federal guidelines recommend that total fat intake be 20-35% of total calories. Saturated fat intake should be less than 10%, and trans fat consumption should be kept as close to zero as possible.
