Dietary Cholesterol and LDL Cholesterol

Impact of Dietary Cholesterol on LDL

Dietary cholesterol can increase LDL cholesterol levels, though to a lesser extent than saturated fat 2, 3
The effects of dietary cholesterol on plasma LDL levels appear to be greater at low versus high levels of cholesterol intake 3

Cholesterol-rich foods that are relatively low in saturated fatty acid content (notably egg yolks) have smaller effects on LDL cholesterol levels compared to foods high in both cholesterol and saturated fat 3, 4

The American Heart Association recommends limiting dietary cholesterol to <300 mg/day for the general population 2, 3
For individuals with elevated LDL cholesterol levels, diabetes, and/or cardiovascular disease, a more restrictive limit of <200 mg/day is advised 3, 5
The AHA's 2006 guidelines recommend limiting saturated fat to <7% of energy, trans fat to <1% of energy, and cholesterol to <300 mg per day 6
Periodic consumption of eggs and shellfish can be compatible with meeting these dietary guidelines 3, 4

Presence of other cardiovascular risk factors or existing disease should be considered when evaluating the impact of eggs on cardiovascular risk 3, 6

For healthy individuals without cardiovascular disease or diabetes, moderate egg consumption (up to 1 per day) appears to have minimal impact on cardiovascular risk 3
For those with elevated LDL, diabetes, or established cardiovascular disease, more restrictive limits on dietary cholesterol (<200 mg/day) are warranted 3, 5
Focus more on reducing saturated and trans fats, which have a greater impact on LDL levels than dietary cholesterol 2
Consider the entire dietary pattern rather than focusing exclusively on individual foods 6
