in my non expert opinion, based on things i have heard(personal testimonies) and studies/research ive read, the best diet for someone with bad cholestrol ratio (hdl/ldl) is not to limit cholestrol intake, but to limit carbohydrate and calorie intake. in such a diet, one would want to include fats in their meals to provide energy and nutrients to the body, and also in such a diet one need not remove cholestrol entirely from their diet, just make sure its not too excessive, and this would be accomplished by keeping calories under control. dietary cholestrol isnt the bad guy, its the transporters that carry cholestrol to and from your cells that you need to worry about. eating less cholestrol means less total activity within the transoprters, both going to and coming from the cells. more cholestrol means more total activity (going to and coming from cells). you want to improve your ratio of good to bad transporters (good=takes it away, bad=brings it to [although i may be wrong on that detail, they could be switched, LOL]). more cholestrol=more good and more bad. doesnt effect the ratio. and the ratio is the most important factor. anyways, i know that most people who get on low carb controlled calorie diets such as the atkins (where you can eat red meat and whole eggs at every meal) experience improvements in their cholestrol levels, and a vast array of other health benefits too.
ha ha "bad cholesterol" WTF does that even mean. People are so misinformed about the subject and mainstream dogma (lower TC at all costs) is mainly due to big pharma pushing statins off onto docs to prescribe.
To fully understand where you are ones needs to know HDL, LDL, Triglycerides, Lipoprotein break down (particle size), and perhaps other things like fasting glucose, CRP, calcium score etc
Basically, dietary cholesterol intake has very little to do with serum cholesterol, which itself may, or may not be, be moderately associated with CVD.
Some chunky guy might go into his doc but have low Trig ( due to a low sugar, low carb diet) yet have very high HDL and normal LDL and have fantastic arteries yet their TC (total cholesterol) is "high" and their doc wants to put them on toxic worthless statins that do nothing but reduce inflammation (which you can do for free by eating less wheat and sugar)
Another guy with "good" TC might actually be a walking heart attack with super low HDL and small dense a Lipoprotein profile (very deadly). He might be thin but have high fasting glucose ( a strong risk factor for atherosclerosis) and massive chronic systemic inflammation of the arteries.
Eat your steak and egg yolks. Lay off the bagels and doughnuts.
If you are worried about your CVD risk check out a cardiologist who knows his shit. A guy like this: http://heartscanblog.blogspot.com browse through his blog and prepare to learn.
Low cholesterol is associated with depression, increased mortality etc. Your brain and body need cholesterol to function. Not sugar, not junk food, but whole/natural foods.
