For the most part, it is okay to eat the things enjoyed before being pregnant, but there are some foods that should be avoided. Some foods to avoid include raw eggs, sushi, unpasteurized juice, and high levels of caffeine, according to the website Parents. Smoking and alcohol use should definitely be avoided during the entire pregnancy.
While there appears to be an association between a woman's diet and the gender of her baby, there is no scientific evidence that diet affects the gender of an unborn baby, as stated on WebMD. Another food to be wary of is certain types of fish that might have higher mercury levels, such as swordfish and shark. Instead eat limited amounts of low-mercury seafood, such as pollock, shrimp and tuna.
