Thanks for your response. I have had a look at Dr Brown’s website, but I am unconvinced about the alkaline diet stuff which seems to be a big part of her focus. Do you know of any hard scientific research which specifically supports the idea that the food we eat causes changes to the pH of our blood, resulting in the body using calcium etc from bones as a buffer? Lots of people claim that it does, but all the science I have been able to find on the topic supports the opposite idea – that blood pH is maintained by other mechanisms & is not affected by food intake (and that pulling minerals from bones is not one of the mechanisms used by the body to control blood pH). I’d be very interested to read any such research if it exists, because none of the proponents of this view that I have come across have actually provided proof of this being the case.
