PH levels & adrenal &/or thyroid correlations?

I am both hypoadrenal & hypothyroid & am on meds for both conditions. Just yesrerday with those little ph strips I found out I am really acidic, 5.5 all day, & I thought I was eating really healthily.

I was wondering, please, if there is anything I ought to know or do in relation to becoming alkaline in order to best help my health, specifically those two conditions. I have started using baking soda, but have ordered some alkaline drops for later use. I am studying the dietary advice on alkalinization too, tho it seems conflicting. One place says eggs, popcorn, milk & strawberries are acidic, & another place on the net says they are alkalinizing!

I am also wondering if being acidic can lead to hypothyroidism and/or hypoadrenalism, and if my correcting to normal alkaline levels can help counter those effects & maybe cause me to need less medication and, particularly with the adrenals, get healed more quickly?

Any input or advice much appreciated as always! :-)
