Despite the vitamin E, vitamin K and heart-healthy unsaturated fat content of vegetable shortening, it has two major nutritional drawbacks. One is the 3.2 grams of saturated fat present in one tablespoon of the shortening. According to the Harvard School of Public Health, limiting your intake of saturated fat to 7 percent or less of your total caloric intake can drastically cut your risk of heart disease. Depending on how many calories you consume each day, that tablespoon of vegetable shortening can be a significant amount of that limit. Even more dangerous is the 1.7 grams of trans fat the tablespoon of vegetable shortening contains. Aim to completely eliminate trans fats from your diet because they raise bad cholesterol levels, lower good cholesterol levels and increase your risk of heart disease, reports the Harvard School of Public Health."

If you disbelieve me that trans fats are killers, I will look up actual studies for you.
