Thanks to Stephen Zwick of Regenetarianism for sending this one.

Charoenwoodhipong, P., Zuelch, M. L., Keen, C. L., Hackman, R. M., & Holt, R. R. (2024). Strawberry (Fragaria x Ananassa) intake on human health and disease outcomes: a comprehensive literature review. Critical Reviews in Food Science and Nutrition, 1–31. https://doi.org/10.1080/10408398.2024.2398634

From the Abstract

Of the 60 articles included in this review, 47 were clinical trials, while 13 were observational studies. A majority of these studies reported on the influence of strawberry intake on cardiometabolic outcomes. Study designs included those examining the influence of strawberry intake during the postprandial period, short-term trials randomized with a control, or a single arm intake period controlling with a low polyphenolic diet or no strawberry intake. A smaller proportion of studies included in this review examined the influence of strawberry intake on additional outcomes of aging including bone and brain health, and cancer risk. Data support that the inclusion of strawberries into the diet can have positive impacts during the postprandial period, with daily intake improving outcomes of lipid metabolism and inflammation in those at increased cardiovascular risk.

Funding: This work was supported by the California Strawberry Commission (CSC). PC, MLZ, and RRH received financial support from the CSC for this work.

Disclosure statement: No potential conflict of interest was reported by the authors.

Comment: I can never get over how industry-funded authors do not view industry funding as a conflict of interest when so much evidence confirms that such funding strongly influences research design and interpretation.  For the record, I review that evidence in my book Unsavory Truth: How Food Companies Skew the Science of What We Eat.

This sure looks like a standard industry-funded study with a predictable outcome favorable to the strawberry industry in this case.

Strawberries are a fine food, delicious, nutritious, and obviously healthful.  But a superfood responsible on their own for disease prevention?

How I wish.

This is marketing research.
