Regardless of what receipe you use, avoid trans fats and you will be surprised at what they are in and cut down on saturated fats to almost zero ( you need a little but not much) and cut the red meats. Keep the cholesterol count low and walk, walk, walk if your hubby is able, at least 30 min a day. It doesn't have to be speed walking but out and moving, or ride a stationary bike. I have had 4 stents and a valve repair (which hasn't lasted) have two other valves leaking, but they won't do surgery again unless it gets to be on almost an emergency basis, as I could wind up in worse shape than I am now. Surgery would be AT LEAST 5 hours or longer, so until I have to do it am not going to. Don't relish being opened up again if I can avoid it.
I find margarines are the worst culprits. I don't like them to begin with but have found a butter spray that does suffice up to a point. I grew up on the real butter and I still like it but of course it is a no=no.
Good luck and you can modify a lot of your present receipes.
