--What is "YOUR" body made of ?--And How !--

What is a carbohydrate? It is a family of chemicals that have the general formula C_x(H2O)_n, what you suggest as a carbohydrate; C1H2O1, is really methanal, you may know it better as FORMALDEHYDE. The chemical they use to store organ and tissue samples in bottles, this is a toxic material to cells and the body does all it can to get rid of it.

Plants do indeed contain carbohydrates in various forms, and eating them does provide the consumer with energy, but they are not converted into carbohydrates body for the most part. True some of it is eventually converted into glucose and glycogen but this glucose and glycogen can also be converted from fats and proteins.

How are they turned into flesh and bone?  Well, this is a complicated process which involves various biochemical pathways for fats, protein synthesis and glyco synthesis, as well as what is called post translational modifications.  It involves various genes and gene regulators, the major players are RNA, DNA, and  Ribosomes.   To start the carbohydrates are broken down enzymatically by the body.  What does not happen is that they react with stomach acids and they do not react with carbon, oxygen or alkaline minerals.

Needless to say EM energy is not released in the digestive system, but it is true that EM travels at the speed of light – but only in a vacuum.  So the rest of the claim that it travels to different organs needing repairs is just dumb.  Besides EM travels in straight lines so it would just radiate omni-directionally without any intended direction.

We can detect EM from Billions of light years away, or from a few atoms.  We can detect the EM from the longest to the shortest wavelengths and EM has never been detected in the manner in which you describe.  The reason is that chemistry does not happen this way.   EM is not affected by pH, nor is pH associated with EM.

Carbohydrates are not generally bound with alkaline minerals, in fact carbohydrates are more likely to react with conjugate bases of strong acids, good nucleophiles include: I^-, HS^-, RS^-, Br^-, HO^-, RO^-, NC^-, N₃^-   However none of the acids exist in the body.  This is just benchtop chemistry which requires a ton of heat from a Bunsen burner and hours of bubbling.

Simply put, a Carbohydrate will not react with an alkaline mineral. 

Vitamins may be acidic, but they don’t have to be, either way, they will not affect carbohydrates nor will they react with oxygen, or alkaline minerals.

Oxidation and Reduction happen in tandem.  Oxidation is the loss of an electron, this happens when there is a significant difference in electronegativity between the two reacting agents.  Oxidation does not as you suggest use up oxygen or alkaline minerals.  And again EM energy is not released.

Finally note that the difference between Carbohydrates and Carbon is more than just a Hydrogen and Oxygen.  The very chemistry is different.  If not maybe you could eat a diamond and for water ( for H and O) when you are short on Carbohydrates
