Diet for a healthy non-smelly vagina?

Just curious what I can be eating and drinking for a healthier vagina?

I noticed my vagina has an interesting odor sometimes and I have discharge sometimes as well. It’s never itchy or super smelly. Never burns. But there has been times my hubby will say it smells like cat food lol. What ever that means. I just wanna be the healthiest possible and taste and smell decent for him.
