How do they relate breastmilk feeding with eventual diet of your baby?

Breastmilk is a non-static, living, dynamic fluid that takes on the flavours of the mother’s diet (unlike formula, which always tastes the same). Some research has shown that children who have been breastfed will more easily accept a wider variety of food tastes (subject to their personality as well). So, the longer you breastfeed, then in theory the more accepting your toddler will be to varying flavours (particularly, say, if you have a preference for strongly-flavoured ethnic foods).
