Hello dear
I understand your concern
Postinor 2 is 95 % effective in preventing the pregnancy.
So failure rate is 1-5 %.
Postinor 2 inhibit the ovulation so no fertilization and implantation will occur.
It also cause delay period by 8-10 days.
So if your next period will delay by 12-14 days, then go for Urine pregnancy kit and or blood HCG to confirm pregnancy.

You can eat any type of food after postinor 2.
There is no interaction between type of food and effectiveness.
Avoid stress, take healthy diet and drink plenty of water
Hope this may help you
