Alan Greene: Yes Female Speaker: Does what you eat during pregnancy determine allergies? Alan Greene: Answer a lot in the book about allergies because in specifically because the allergies at present so quickly in the US up until about 1996 those stayed level and they have been increasing really rapidly since then and so I do talk about during pregnancy what foods to avoid and what foods actually help to prevent allergies if you are getting them in and all the way through childhood but there is one really important thing for kids that is revolutionary most pediatricians still say that you should only feed one new food every 3 to 5 days, because of allergies and when you ask them about so what is what you mean by that line and they say well it probably increase allergies but it helps you figure out what they are allergy too and its true its easier to know but you are given up so much because kids learn to like food is been studied in placebo controlled studies its solidly true that the faster you introduce foods they more they like and the more mixtures they get at the beginning the more they like and the more adventures they become. And there is no food that there is evidence to delaying it beyond 6 months reduces allergies peanuts, eggs, fish in countries were they feed a lot of fish to 6 months old like all of Scandinavia the have less in the way of allergies and even in the same group were they parts of the family that live in European parts some live in Israel when they cut peanuts and they are from different ages but all through they get the peanuts the less lightly they are to become allergic and that’s all in the book to the studies this is. Yes DES story, okay tell the story. So I mean the best about the story this is I think one of the greatest failures of medical profession in my life time. There was a medicine DES that was given to pregnant women in order to help them not having miscarriages this practice started in the 50’s and there was actually placebo controlled studies showing in the 50’s so with it nothing to help and doctors knew this. But we decided we collectively decided that you know there is so terrified of either having miscarriage if had a miscarriage people what harm could it do lets just give it any and then feel better. So millions of women who were pregnant would give DES or synthetic hormone throughout the 50’s and 60’s and it was until the 1970’s beginning of 72 that it was suddenly pulled from the market because the girls who were born during from those pregnancies were having an early age like 8 years old, who are having cancer in the Virgina Renal cell carcinoma really were tumor and started happening in all the moms that had this DES so its is stopped in the market. That we didn’t know at that time that had longer lasting health impacts it wasn’t until those kids grew up that we learned with those daughters who were less like to be fertile. It wasn’t till those women who took till were older that we learn that it cause breast cancer in those women who took it and in this CDC that cause a modest increase in breast cancer but which mean 10 to 15% which means 100’s of 1000’s of women in the United States had breast cancer who would not have had other wise because of ineffective medicine that we gave them to help and feel better because it couldn’t cause a problem and we now know that the grand kids the little boys who just recently studied and we know that they are 20 times more likely to have what’s called hypospadias with that the opening at the tip of the penis isn’t it some one down along the shaft. So this hormone in very tiny doses has had an generational impact that what most people don’t know now about the DES story is at the same time that is started being used in pregnant women. In the US we started using it in cattle because it plug put the cow’s into premature puberty they would have growth sprouts they got fat cheap and two thirds of the beef cow’s in United States were fed DES and
