Anyone give advice?

I’m wondering what you ladies eat/drink that help your ph? I know pineapple juice is good and probiotics but is there anything else? I’ve noticed a smell coming on but tested negative for bv and yeast. I’m hoping if I add a few things into my diet and keep up good hygiene I’ll be fine. It’s just my vulva that smells not my actual discharge. Is this kind of smell Normal? I can’t describe the smell other than it’s quite “ tangy” and sour.
