I think he meant an over time aquired food allergy. Esp. Older folks seem to get them -like me- one can test with a Serum specific IgE in vitro Test. There are over the counter test one can buy relatively cheap.
I did one recently, turned out I was allergic to garlic of all things (among others). Advice is to stay off it for 4-6 months then slowly reintroduce. Life is wild sometimes.
I personally know someone who uses something he calls "Dutch reach-around" and while I'm hazy on the details, I know it starts with some complex setup of a charitable foundation in your home country, with real people and real money and a network of firms and other foundations in the Netherlands that are somehow interwoven. He told me "setup is cheap, only 5 million dollars up front, you can ask my tax attorney for the deets"....
That was a nice move, but no thank you, this is not the kind of money I have lying around.
Bonus how us firms do it, I imagine this costs also a lot of money up front...
