What Foods Should Be Avoided During Yeast Infections?

HELLO, I AM TYPE 2 DIABETIC , I HAD SURGERY 3 WKS AGO FOR RECTROCELL AND SOME GYNO REPAIR. I NOW HAVE A SEVERE YEAST INFECTION BECAUSE MY INSULINIS RANGING 177 AND AC1 IS 7.2. I KNOW IF YOU TAKE ANTIBOTICS IT KILLS THE GOOD BACTERIA AND YEAST THRIVES. I DID NOT KNOW WATERMELON WAS HIGH IN SUGAR AND I HAVE BEEN EATING A LOT OF IT . ARE THERE ANY FOODS I SHOULD AVOID???
