Healthy Eating Frustrations

I'm still struggling with this "healthy cooking" I'm supposed to be doing.  I've spoken to several nurses and dieticians over the last few weeks, and I've gotten some conflicting information.  One nurse told me that olive oil is the absolute worst kind of oil a heart patient could eat, because, according to this nurse who obviously shouldn't have been speaking, it was a saturated fat.  Olive oil is not a saturated fat.  Others are telling me to feed Mom things that in my dietary belief system are not real foods.

Have you seen this chart from SummerTomato around the internet?  It's been passed around on Facebook a lot lately.  I love it, and think it explains clearly how to eat.  Of course my flow chart would add "was it locally grown?"  This is proving to be my biggest frustration in learning how to cook in a heart healthy way.  I'm learning that most people have no concept of what it means to cook completely from scratch or what food without a label is.  I'm trying to find out if it's ok to add any salt at all when I'm cooking, and they just keep telling me to read the label on the food.  I say, no, I'm starting with fresh whole food that is not packaged or processed, and they tell me to read the label.

The nurse today told me not to add any salt to food I'm cooking from scratch, for instance, fresh cauliflower (1 cup raw: 30 mg sodium ), but it's ok for Mom to have a Jello Pudding cup (1 snack cup: 190 mg sodium).  Somebody please help me understand the logic in that!

I think I'll go talk to my granddaughter on webcam to get my mind in a better place.  If you know of any heart healthy and good tasting recipes that are made from real food, please share!
