A frozen apple pie seems harmless, but this dessert option is one you should simply say no to. Take Marie Callender’s apple, for example—it’s packed with hydrogenated oils, so one slice has a whopping three grams of trans fats. Trans fats can increase your risk of cardiovascular disease, and a slice of pre-made pie just isn’t worth damaging your heart’s health.

Eating it as part of a meal with vegetables on the side can make a smaller portion go further. Having a pie or pasty as a snack is not such a good idea – it is high in calories and you may still eat a normal meal later.
