Fine. The cancer still can't tell if the glucose is processed or not.
drinking phosphoric acid is not so natural. It greatly depresses body Ph.
What's the pH before you drink it? What is it after?
Test it your self with a Ph test strip. Do not drink or eat anything for 20 minutes before the test or residuals in your mouth will throw the test off. Test your saliva, drink a soda, and wait 20 minutes and test again. If you test closer than 20 minutes the residual soda will throw the test way acid and give you a false reading. (Ans: lower or more acid, depends on body mass, contents of stomach and quantity of drink)
Second test: Test, then drink a solution of one teaspoon to one table spoon natural cider vinegar (a natural acid!) stirred into a tall glass of water. Wait 20 minutes and test again. Your Ph will read 1 Ph level... Higher! (Ans: While vinegar is acid, when it is digested it is alkaline.) If it was simply the acid balance of what you drink, your ph should be lower just like the soda, but it is actually higher. (again, YMMV. Do on empty stomach for best results)
Third home science experiment, drink the same amount of white vinegar or cheap non natural apple cider vinegar stirred into a glass of water like above. Your Ph will be shifted acid, not alkaline. Cheap apple cider vinegar is actually white vinegar with apple flavoring. Tastes the same but not the same effect with the body.
By the way, Apple cider vinegar has been for years a back woods cure for many a thing. (My guess, all of them fungal) The trick is to switch the fungus off and into its spore phase or seed phase by making the environment alkaline. Works decently with most stomach "flu" or "food poisoning" cases. They are bad fungus, not viral or salmonella, they are "diagnosed" at home, and not by a real doctor. And in most cases the diagnosis is wrong.
WARNING, DO NOT DRINK PURE VINAGAR, it will burn the snot out of your throat and piss you off at me. STIR into WATER. More than two table spoons of vinegar in a 16 oz glass of water or not stirring it in can irritate your throat badly.
Don't want you irritated, want you healthy!
