Personal trainer here. All things should be done with balance and not excess. There is nothing wrong with eating cake, fried foods, candy, soda, etc...As long as you do it in moderation. Obviously these items are not good for your body but you only live once. You want to enjoy the things that taste good in life. Saturated fats taste great, enjoy them once in awhile...Just don't make them a regular part of your daily diet.
