Does going vegan help balance your ph ?

I've been wanting to go vegan for the longest time now and I'm slowly educating myself on it rather than just jumping right into it but I was just wondering ... I struggle with yeast infections pretty much my whole life ( I'm 19 been having them since I was little ) I'm getting my second boric acid treatment that goes on for 6 months it helps a lot but I eventually start getting them frequently again and I was wondering if maybe my diet plays a role in it ? Have any of you gone through the same and once you changed your diet it became less frequent or completely stopped getting yeast infections all together ?
