No I don't. Perhaps I should do more homework. I was appealing to common sense. If there is a famine or drought, people are starving and thirsty. Making milk is a lot of work and requires at least marginally decent nutrition. If someone is only eating one "meal" a day and drinking 2-4 cups of water a day, there's just not much with which to make milk. N=1 anecdote, my daughters mother was very easily able to tell how her diet affected breastfeeding. A lot of it had to do with water intake.
