I think that's the trick aw well. It's also smart to research foods. For instance fresh pork sausage (not the kind with preservatives) is very low in cholesterol. And I'm pretty sure our bodies needs at least some cholesterol.
A variety of foods - especially with an emphasis on vegetables, fruits, and nuts - is key, along with proper exercise of course.
Makes no difference because there is zero relationship between high [or low] cholesterol food consumption and serum cholesterol.
In weighing the value of this study, you should consider the fact that these same people told us to avoid eggs, shrimp, whole milk, beef, and other foods high in dietary fat and cholesterol for over three decades, and encouraged the consumption of more cereals and grains.
We now know that the body's production of cholesterol is almost entirely a function of carbohydrate metabolism, and the diet they were encouraging at-risk people to eat was EXACTLY the wrong one.
