About Dr. Katharina Dalton

Hi Wray, I've seen you mention Dr. Dalton's studies and practices before and as I had never heard of her, I googled her name. Amongst the results I cam across this site about her: http://www.bmj.com/rapid-response/2011/10/30/katharina-dalton-and-progesterone-dangers

In the article it talks also about the adverse affects of Progesterone. Here's is quote from some of it:

"Removal of the ovaries has long been used to prevent endogenous progesterone production as a treatment for breast cancer. Recent studies confirm that progesterones cause more breast cancer than oestrogens. Progesterone is also potentially teratogenic."

Is this true? I always thought it was estrogen that was the "bad" hormone to increase cancer risk. Hence all the hoopla with the risks of HRT over the years. If this study is true then surely this is big news and we should duly take note. But I know you are a better study than me because of the reading you've throughout the years. But this seems to be fairly new study results and maybe needs to be researched more.

Now I'm a little scared....

I would be very interested on your thoughts on this article.

About Dr. Katharina Dalton

Hi Nikki When I started reading it I thought the author must be on some mind altering drug! Then I discovered it was Ellen Grant who wrote it. If you read her other papers, you'll find she is very confused by progestins and progesterone. Look at the titles of the few papers she gives as references. And she doesn't give the refs for the breast cancer 'studies'. Now if she means progestins, which I know she does having read her other work, then yes I entirely agree with her. You might like to see this video here. And this paper here. This is an older paper which is quite unequivocal in it's conclusion. And teratogenic......huh? Why is it called the pregnancy hormone? Why is it so important for pregnancy and the foetus that without it no woman will carry a child to term? Why does the female body increase production ten fold whilst pregnant? Why is it that the majority of infants born are not deformed? Surely this in itself is proof that nothing could be further from the truth! If you want further confirmation that Grant is talking nonsense, please contact Dr Judy Evans who's crossed swords with her before. I do agree with her comments about small, frequent, starchy meals, I'm not in favour either. And I don't agree with Dalton's take on vitamin B6. Take care Wray
