Hi hun, I'm sorry you and DH are so worried right now.
My father has always had high cholesterol What he did/does differently is that he doesn't eat any fried foods, doesn't cook anything in any kind of oil, he loves peanuts and he stopped eating those, eats only egg whites, watches his fat, replaces part of the saturated fat in his diet with unsaturated fat. Also Cheerios is really supposed to help reduce cholesterol. He still allows himself to splurge every now and then though. He also exercises 5x a week. He's now on Lipitor as he's been dealing with this for many years without medication and it just got to be too much on his body.
Eating more fruit and vegetables (especially raw veggies) is also a great way to reduce cholesterol and the fiber in fruit acts like a sponge and soaks up the cholesterol and gets it out of the body.
Avocado also reduces cholesterol by 8%.
Please don't blame yourself hun.
It isn't your fault!! Much of it is hereditary. Take my brother for example, he's 34 years old, is a powerlifter so he's in excellent shape and his diet is immaculate, yet he has high cholesterol.
