How unhealthy is it to eat pizza in the last month of pregnancy? Can you eat the pineapple on it?

Moderation is the key! As long as it is fully cooked and not raw you can definitely eat it. For pineapple, it is okay to eat in small amount. Bromelain, a type of proteolytic enzyme found in pineapple, helps to soften the cervix which could ease the labor, but it should be consumed in larger quantities. http://www.momjunction.com/articles/safe-eat-pineapple-pregnancy_002951/
