Breastfeeding diet

Hi breastfeeding mummies, any of u control your diet while u breast feed? Does it really affect the baby when baby drinks the milk? There seems to be so many and too many food that cant be eaten. Especially now that i am still in confinement, ive heard breastfeeding mummies cannot eat and drink herbs or chicken essence etc as it will affect baby. But being on confinement, we need herbs and those food to replenish energy. Anyone can share your experience? Should i eat or should i not?
