Is it true that dietary cholesterol from eggs significantly raises blood cholesterol in healthy adults?

Worth knowing

• •Individuals vary considerably in their cholesterol response to dietary cholesterol — so-called 'hyper-responders' may see more pronounced LDL increases than the general population.
• •The type of LDL particle raised matters: eggs appear to preferentially raise larger, less atherogenic LDL particles rather than the small, dense LDL most associated with cardiovascular risk.
• •The overall dietary pattern and baseline diet quality significantly modify the effect; egg intake paired with a high saturated fat diet may have different outcomes than egg intake on a healthier background diet.
• •Most evidence in this area focuses on healthy adults; the relationship may differ in people with diabetes, metabolic syndrome, or existing cardiovascular disease.
• •HDL-cholesterol tends to rise proportionally with LDL in response to egg consumption, which may partially offset cardiovascular risk implications.

• Association between Egg Consumption and Cholesterol Concentration: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

  Li et al. · Nutrients · 2020 · PMID 32635569

  A meta-analysis of RCTs found that higher egg consumption raised LDL-cholesterol and the LDL/HDL ratio compared to control groups in healthy individuals.

  Supports the claim

  Meta-analysis of RCTs in healthy populations found egg consumption raised LDL-cholesterol and LDL/HDL ratio.

• The Effect of the Consumption of Egg on Serum Lipids and Antioxidant Status in Healthy Subjects.

  Kishimoto et al. · Journal of nutritional science and vitaminology · 2016 · PMID 27928124

  Consuming one egg per day for four weeks did not significantly change serum LDL-cholesterol, and actually increased HDL-cholesterol while reducing the LDL/HDL ratio.

  Contradicts the claim

  One egg daily for 4 weeks did not change LDL-cholesterol and actually improved the lipid profile in healthy subjects.

• High-density lipoprotein cholesterol changes after continuous egg consumption in healthy adults.

  Mayurasakorn et al. · Journal of the Medical Association of Thailand = Chotmaihet thangphaet · 2008 · PMID 18575296

  Twelve weeks of one additional egg per day significantly raised HDL-cholesterol and reduced the TC/HDL ratio, with no significant change in LDL-cholesterol.

  Contradicts the claim

  One additional egg daily for 12 weeks increased HDL-cholesterol and reduced TC/HDL ratio with no significant LDL change.

• Consumption of Eggs Alone or Enriched with Annatto (Bixa orellana L.) Does Not Increase Cardiovascular Risk in Healthy Adults-A Randomized Clinical Trial, the Eggant Study.

  Galvis et al. · Nutrients · 2023 · PMID 36678239

  Daily consumption of two eggs for eight weeks did not significantly alter lipid biomarkers of cardiovascular risk compared to egg white consumption in healthy adults.

  Contradicts the claim

  Two eggs daily for 8 weeks did not significantly alter lipid biomarkers in healthy adults.

• Egg consumption, cardiovascular diseases and type 2 diabetes.

  Geiker et al. · European journal of clinical nutrition · 2018 · PMID 28952608

  A review of high-quality intervention studies found nonsignificant effects of increasing egg consumption on cardiovascular risk markers in healthy subjects, with confounding by overall dietary patterns noted in observational data.

  Contradicts the claim

  Review of high-quality intervention studies found nonsignificant effects of increased egg consumption on cardiovascular risk markers in healthy subjects.

• Intake of up to 3 Eggs per Day Is Associated with Changes in HDL Function and Increased Plasma Antioxidants in Healthy, Young Adults.

  DiMarco et al. · The Journal of nutrition · 2017 · PMID 28077734

  Consuming up to three eggs per day increased large LDL and large HDL particle concentrations and improved antioxidant status, suggesting a more favorable lipid profile shift than raw LDL numbers imply.

  Neutral

  Focuses on HDL function and particle size rather than the direct claim about blood cholesterol raising.
