What food items can lower high cholesterol level,and what are the foods allowed/not allowed?

my boss had hyperlipidemia,had heart attack,went comatose for 18 days.now he had memory loss and brain anoxia, and at times has to take .25 mg clonazepam for panic disorder.

Nuts, avocados, fish, and seeds. Salmon have an acid in their mega oil which cuts down on cholesterol. Olive oil is very good too. I also ate a lot of oatmeal as cereal and in cookies. Shell fish, red meats high in fat, organ meat, cakes, pies and pastries are not good for anyone trying to lower cholesterol. Also stay away from fried foods of any kind. Exercise is also important.

Along with the previously mentioned, whole grains, fruit and vegetables
