Proposal and other issues aside, I’m not sure you rely on food served to be food consumed. Prisons in most places still buy food at commissary.

But I’ll agree that you might be able to quantitative compare prison A vs prison B if you can get a control prison and account for differences. Just a diet of 20% more carbs between A/B would be interesting.

I imagine someone has “done science” on prisons in other areas already. Way more ethical than the typical proposals I see for prisoners/prisons on the internet.

Every time I've considered how to really do nutrition research, it essentially amounts to a prison, even if voluntary. You would need to be able to lock different populations away from any source of food than what you provide, and control their daily activities, etc, for at least 2 years, though you could likely get some results after only 6 months.
