In recent years, eggs have been a topic of debate, with concerns over their impact on cholesterol levels and heart health. Many people believe that consuming eggs regularly can lead to increased cholesterol and a higher risk of heart disease. However, new research presented at the American College of Cardiology’s Annual Scientific Session challenges these notions.
The study, conducted over four months, investigated the effects of consuming fortified eggs on cholesterol levels and heart health among 140 patients with high risk for heart disease. Surprisingly, the results revealed that individuals who consumed 12 or more fortified eggs per week had similar cholesterol levels compared to those who ate fewer than two eggs weekly.
Lead author Nina Nouhravesh emphasized the importance of dietary patterns in maintaining heart health. The team specifically focused on fortified eggs, which contain less saturated fat and additional vitamins and minerals essential for overall health, including iodine, vitamin D, selenium, vitamin B2, B5, B12, and omega-3 fatty acids.
"This study provides reassurance that eating fortified eggs does not adversely affect lipid levels over a four-month period, even among individuals at higher risk for heart disease," stated Nina Nouhravesh, a research fellow at the Duke Clinical Research Institute in Durham, North Carolina.
During the study, participants aged 50 or older were randomly assigned to either the fortified egg group or the non-egg group. Vital signs and bloodwork were regularly monitored throughout the study period. Although no significant differences in cholesterol levels were observed between the two groups, potential benefits of fortified eggs were noted, particularly among older patients and those with diabetes.
While the fortified egg group showed slight reductions in HDL-cholesterol (good cholesterol) and LDL cholesterol (bad cholesterol), these changes were not statistically significant. However, the findings suggest that consuming 12 fortified eggs each week had no adverse effects on blood cholesterol levels.
In addition to cholesterol levels, the study examined secondary endpoints, revealing potential improvements in total cholesterol, LDL particle number, apoB (another lipid biomarker), high-sensitivity troponin (a marker of heart damage), insulin resistance scores, and increased vitamin B levels in the fortified egg group.
Despite these encouraging results, experts caution against unhealthy dietary practices often associated with egg consumption, such as pairing eggs with buttered toast and bacon. Nina Nouhravesh advised individuals with heart disease to consult their healthcare providers regarding dietary options and overall heart health management.
While the study indicates that fortified eggs may be safe for heart health, it is essential to acknowledge the study's limitations, including its small size and reliance on self-reported data. Continued research and discussions with healthcare professionals are crucial for making informed dietary choices that support heart health and overall well-being.
