Industry-funded study of the week: Eggs

Here’s another in my series of post-Unsavory Truth examples of studies whose funder can be predicted by their titles.

The consumption of 12 Eggs per week for 1 year does not alter fasting serum markers of cardiovascular disease in older adults with early macular degeneration Hassan Aljohia , Mindy Dopler-Nelson , Manuel Cifuentes , Thomas A. Wilson.  Journal of Nutrition & Intermediary Metabolism 2019;15:35-41.

Hypothesis: Egg consumption is associated with reduced risk of macular degeneration, but because eggs are so high in cholesterol, they might increase the risk for cardiovascular disease.

Conclusion: “This study suggests that the consumption of 12 eggs per week for 1 year does not significantly alter fasting serum lipids, lipoprotein cholesterol, or other biomarkers of CVD in older adults diagnosed with early macular degeneration” [the hypothesis is shown to be false].

Funding: “The authors would also like to thank the American Egg Board, Egg Nutrition Center, Washington, DC (T.A.W.) and the Massachusetts Lions Eye Research Fund Inc., New Bedford, MA (T.A.W.) for their funding support. The funding played no role in data collection, analyses, or interpretation.”

Comment: So the authors say, but industry influence is often unrecognized.    Independently funded studies sometimes come to quite different conclusions, as one in JAMA did last week.  Its conclusion: “Among US adults, higher consumption of dietary cholesterol or eggs was significantly associated with higher risk of incident CVD and all-cause mortality in a dose-response manner.”
