So does pineapple juice and cranberry juice/pills actually help to make you taste better???

so i bought some pineapple juice to see if it will help my strained throat because im sick, then i got to thinking if i should make it a daily part of my diet. people with vagina's/uterus (forgive me, i havent heard of men who do this) who have tried this, any changed or improvements to your ph?? better taste?? i always wash myself before sex and my boyfriend says i taste fine but thats without any prior enhancements. thoughts?
