The taste of breast milk is VERY dependant on what you are eating/ putting into your body, breast milk will almost always taste like food that the mother eats, kind of watered down and, well, milky. I was expressing in the shower one day and accidently got myself in the face, after I got over the shock, I was amazed at how much it tasted like the chicken dinner I had the night before! It is very good for babies and although not a very good source of nutrition for adults, it isn't BAD for you.
