>This premise assumes we understand, with no uncertainty, how the human body functions and utilizes nutrients [but] this is still a huge mystery to science
If "no uncertainty" was the golden standard, we'd never do anything new (except perhaps mathematics). Yes, there is uncertainty in what he's doing, as there is always when trying something truly novel. But I'm sure glad someone is making the attempt. Nutrients are not a huge mystery to science - there are entire college courses on biochemistry and such.
It is really easy to figure things out at the cellular level because you can easily build experiments containing controls and the turn-around time on iterations is fast.
The human body has trillions of cells and even more symbiotic bacteria. We are clueless how the system functions as a whole. We know some simple things (iron and calcium compete for absorption in the intestine), but only the "big" stuff.
Maybe if you eat 20% of your RDA of Vitamin E at every meal, it makes your intestines toxic to a particular strand of gut biota that regulates half your body[1]. The space we know nothing about is huge, and jumping in with a product for the masses with so little respect for that is, IMO, very dangerous.
1. There is evidence that people suffering metabolic syndrome have significantly different gut biota than those who aren't and when "normal" biota is reintroduced, their health improves. My hypothetical is not an impossibility.
If you set yourself on fire, your flesh will burn and you will eventually die horribly. It is less clear what happens if you expose yourself to repeated small amounts of radiation. See the problem with your logic?
Er, no? People repeatedly expose themselves to small amounts of radiation all the time. X-rays, sunlight, airplanes, astronauts, living anywhere with large quantities of granite rock . . .
Really, that seems to be totally irrelevant to whether or not this guy is on to something. (Personally, I think he's probably running a long con. But making stupid arguments against con men is just a way to send them more victims. Ask for some evidence instead - arguments screen off authority.)
