How many calories in an Apple Pie?

Posted by biochemistryquestions on March 15, 2010

 

Of course, there are many different apple pies, and many different serving portions  too!!!

So…let’s do the calculations with a “standar” apple pie…certainly not the best but it is standard, so standard that it is the same all around the world!

Of course, I am talking about the MacDonald Apple pie!

Nutrition facts of the Macdonald baked Apple pie (taken from the label):

Proteins 2g

Fat 13 g

Carbohydrates 32 g

Sodium 170 mg

How many calories are obtained when you eat 1 serving size of this pie?
