The "dietary cholesterol equals blood cholesterol" view is a standard of dietary recommendations, yet few consider whether the evidence justifies such restrictions.
He notes that studies demonstrate that dietary cholesterol increases both LDL and HDL cholesterol with essentially no change in the important LDL:HDL cholesterol ratio.
For example, the addition of 100 mg cholesterol per day to the diet increases LDL cholesterol by 1.9 mg/dL, but that is accompanied by a 0.4 mg/dL increase in HDL cholesterol.
This, on average, means that the LDL:HDL ratio change per 100 mg/day change in dietary cholesterol is from 2.60 to 2.61, which is likely not even statistically significant and would probably have no influence on heart disease risk.
This helps to "…explain the epidemiological studies showing that dietary cholesterol
