I think that is a bit of a straw man- a sugar lobby represents economic interests. Why would this man's ideological interests not match his academic interests?

Because they virtue themselves as doing unbiased data-based science, when they're just pushing their agenda. At least, the alt-right folks (Milo, Shapiro) are very clear and honest about their bias.

True. It almost seems that science and research as a whole is increasingly just a channel for pushing an agenda. I don't think we've advanced much in that regard. Anyone can fund a study and twist it to support their agenda or just not publish it. Then the media gets ahold of it and cherry picks what they want and use questionable headlines.

In many cases it results in consumer confusion and serious health issues (sugar vs saturated fat war you noted).

I'm sorry for those who, thanks to the MW are,

- because they are perhaps not very bright, maybe mentally-disabled (Downs syndrome people for instance), possibly just naturally very slow, inexperienced, very young, very old, physically feeble or otherwise considered to be unlikely to be productive would-be employees who

- are then legally prevented from getting a job unless of course the state wishes to force employers not to hire the most productive staff to be paid the minimum wage. And that's not going to happen in a free society and nor should it. Everyone has their value. But don't let's pretend that value (for a specific job) is the same for all of us.
