What research shows that urine ph reflects blood ph

I am wondering if the "Ya gotta be alkaline" belief in alternative health circles is valid. I see some people, online, saying Yes and some saying No the blood ph stays the same. None of them seem to be offering any data based research.

I don't like hypothetical arguments, though I know research papers can be unreliable too. I do know that growing up and for many years thereafter I'm sure I no way had a diet that was even half alkaline. Lots of meat and milk and potatoes, even some candies, cereals. There were some fresh fruits & veggies but not as a big part of the diet. Yet I was very healthy.

The reason I really need to know is because I have been mega mega dosing on ascorbic acid for adrenal insufficiency. Nothing helps the adrenals like Vitamin C. But I cannot take sodium ascorbate due to the high salt content and baking soda in it. The ascorbic acid makes me have a very low ph in urine, though the saliva ph is okay.

Who is right on this issue, and what research is there to prove it? Maybe some people just want to sell books about alkalinity as the golden key to health and/or the people who want to sell those ph papers have a campaign going on to indoctrinate the public through fear about the ph levels. Or maybe it's all true. So confusing....... Tweet
