Industry-funded study of the week: avocados again

The study: Effects of replacing solid fats and added sugars with avocado in adults with elevated cardiometabolic risk: a randomized, double-blind, controlled feeding, crossover trial.  American Journal of Clinical Nutrition Volume 123, Issue 2101137 February 2026.

Objective: to assess the effects of replacing energy from solid fats and added sugars with equivalent energy from 1 avocado daily on cardiometabolic risk factors.

Methods: Study subjects were given a diet with or without an avocado a day to replace energy from saturated fatty acids and added sugars.

Results: While on the avocado diet, subjects improved their lipoprotein profiles.

Conclusions: Replacing solid fats and added sugars with avocado in a typical American diet improves the lipoprotein lipid profile in adults with
elevated triglycerides.

Funding: “The Avocado Nutrition Center of the Hass Avocado Board funded this research. The sponsor was allowed to comment on the study design as part of the application process. The sponsor had no role or involvement in the collection, analysis, or interpretation of the data; in the writing of the manuscript; or regarding the submission of the manuscript for publication, regardless of the results of the study.”

Conflict of interest:  The list of disclosed conflicts is much too long to bother to reproduce.  At least 3 of the 12 authors specifically disclose financial support from  from the Hass Avocado Board.

Comment: The disclosure statement is unusally forthcoming.  The funder had input into the study design, the part of the research process where industry influence is most likely to show up.  Funders are most likely to fund research that has the best chance of giving them the answers they want.  This was a cooperative effort to demonstrate the benefits of eating avocados.

I like avocados and appreciate that their fats are largely monounsaturated and benign or good for health.  But the purpose of this research is not about science; it is about avocado industry-sponsored research to market avocados.

I have no doubt the Hass Board would respond to this by saying, “if we don’t fund this kind of research, who will?”

That’s my point.
