I have witnessed and experienced proof of this far too many times to ignore it... people who have worked hard to eat nutrient dense diets through high quality foods have greatly improved their resistance to *sun burning*.
>>"Show us proof that the photons of sunlight has an acidic pH."<<
Photon emission of hydrogen...
>>"Photoelectic effect involves the release of electrons from certain substances when exposed to light. So are you really implying now that electrons have a pH?"<<
Electrons have an *affect* on the pH - again, we can point out potential hydrogen.
>>"I would also like to see your proof that vitamin D is a Lewis acid as you state."<<
You may find lewis acids where you find vitamin D metabolic processes explained that include vitamin D analogues.
I know - technicalities... strictly speaking, semantics, and all of that... however, most of the people we talk to on these forums understand things in simple layman's terms... not technical scientific one's.
