Yup. There's definitely a pattern and it seems like an obvious consequence of the structure of incentives.

If you make a product you can make a study that shows it has some kind of benefit in some specific way, even if it probably causes more harm in other ways that are less obvious, and then you can sell it. Media will spread around your study especially if it shows something that will be a bit click-baity, and any study or discussion of the possible downsides will get far less attention.

This is also why basically every edible plant has some article saying it's a "super food" etc etc.
