A few online studies do interface oxalic acids with chemical imbalance and vulvodynia, yet just a couple of studies have investigated potential associations. Further research is required.
Healthy Foods with Oxalic acid
There are foods high in oxalate. A few critics of low-oxalic acid diets down say people are better to avoid the foods with oxalic acids, since they may have negative health impacts.
