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..............
They also note that dietary cholesterol was not related to serum cholesterol concentration. As a matter of fact, people who reported eating four eggs a week had a significantly lower mean serum cholesterol concentration than those who reported eating one egg a week. (193 mg/dL vs. 197 mg/dL).
The authors conclude that eggs make "…important nutritional contributions to the American diet."
