Kathleen, I shiver at the tought of having such uninformed people calling themselves RDs. But it happens. The best come back you can present this person and whatever comitte you need to convince is the work done by the National Academy of Sciences : "Nutrition durign Lactation". This committe has reviewed all the available data on the topic and the conclusions are that you do not have to have a RD perfect diet to make good milk. When you think about it it makes sense. In the old days women's bodies were much more stressed and nutrition not nearly as abundant and varied than in our country today (over nutrition is now the main problem: look at the incidence of obesity). So in evolutionary terms, our bodies had to adapt to adverse conditions to be able to have the race survie and for us to be here to talk about it today!!!. Good luck] Maryelle
