Where do the elite buy their food?

All of these food recalls, the Taylor Farms debacle, and the questionable state of USA beef and chicken, and just the overall nutrient deficient food sold to the public has me wondering if the ultra wealthy/elite have a black market – of sorts – or a different supply chain, however you want to frame it.

For sure they are generally thinner than the general populace. They eat less and healthier. Still… What about what they do eat? Does Elon Musk's personal chef source from the same grocery stores, or the same big agriculture corporations as the rest of us? Like, does Sysco service the White House, or who does? Do they use the same suppliers? And what about supplements – is there a separate market for that too?

We know they have access to alternative medical treatments and procedures in autonomous (read: lawless) zones like Peter Thiel's Prospera.

Does anyone have any info related to this? Are there autonomous zones dedicated to feeding the ultra rich? Or even just simply private farms with very high standards and rigid protocols dedicated to selling higher quality food to the elite?

Everything with them is inside info and velvet roped access. Why not food?
