Are there any food that i shouldn't eat after circumcision? like seafood or eggs?

Anything: Nothing special. It is likely to heal fine on its own. Keep it clean.

No problem: Circumcision is a simple surgical procedure just like any laceration repair or other skin incision procedure. Vitamin c and high protien diet may help with tissue building and healing. You don't necessarily need to avoid any specific foods unless you are already allergic. Pay attention to routine wound care, making sure there is no redness, heat, pain, swelling, nor discharge.
