Industry-funded review of the week: Seafood!

Seafood intake and the development of obesity, insulin resistance and type 2 diabetes.  Bjorn Liaset, Jannike Øyen, Hélène Jacques, Karsten Kristiansen and Lise Madsen. Nutrition Research Reviews (2019), 32, 146–167.

Conclusion: Evidence from intervention trials and animal studies suggests that frequent intake of lean seafood, as compared with intake of terrestrial meats, reduces energy intake by 4–9%, sufficient to prevent a positive energy balance and obesity. At equal energy intake, lean seafood reduces fasting and postprandial risk markers of insulin resistance, and improves insulin sensitivity in insulin-resistant adults… More studies are needed to confirm the dietary effects on energy intake, obesity and insulin resistance.”

Funding: The present review was financially supported by The Norwegian Seafood Research Fund…The authors declare that they have no competing interests.

Comment:  It is understandable that the Norwegian seafood industry would support research to promote seafood consumption.  Seafood is a demonstrably good source of animal protein but how good, how essential, and how environmentally sustainable are highly debatable.  To the authors’ credit, they acknowledge the debate when they admit that “more studies are needed….”  Industry-funded studies tend to put a positive spin on equivocal research, as this one does [I provide evidence for these views in Unsavory Truth].
