I guess everyone is sick of the subject so this is my last post on the topic. I questioned how researchers measured toxins in breastmilk and whether they took into account how the fat composition of breastmilk changes. Well, I had a look at a heap of studies and they all avoided that problem by expressing the level in contamination as a function of g of fat. Thus, accuracy is only a problem when they attem[pt to calculate the dose of toxin injested by the baby because at this point they have to work out how much fat the child is getting.
