Diet while pregnant affecting babies likes/dislikes

Does anyone know if there's any correlation between what you eat while pregnant and what your baby will like/dislike as a child. Or can anything you eat affect allergies of your baby? 
For example, my so has a shellfish allergy, will me eating shellfish affect my baby in any way good or bad?
Or if I eat a lot of strawberries or something while pregnant will my baby love strawberries?
Just curious if there is any info on this
