"At the end of their paper, Dr. Hazen’s group cautions against “excessive consumption of dietary phosphatidylcholine and choline” and recommends a high-fiber, vegetarian diet as a means of protecting against heart disease.
Yet as I’ve argued above, they failed to present convincing evidence that eating eggs significantly increases TMAO over time—especially when compared to other foods like fish. Moreover, if eating choline-rich foods did increase the risk of heart disease (via TMAO or any other mechanism), we’d expect to see higher rates of CHD in those that eat more eggs. Yet numerous studies have failed to find any such association. For example, a meta-analysis of prospective studies involving a total of 474,000 participants followed from 8 to 22 years published in the British Medical Journal found no association between higher egg consumption (up to one per day) and CHD or stroke.
