A medical headline caught our attention today. Between high levels of folic acid in pregnant women and an increase risk of their children developing an autism spectrum disorder. Well our dr. Jon lapook has been looking into this and with us now with a dose of reality. Jon, pregnant women are told to take folic acid. And that stays exactly the same. There is no doubt that women who have too little intake of folic acid in pregnancy have increased risk of having kids with birth defects. So that recommendation from the government, which is to take 400800 micrograms of folic acid a day in pregnancy stays the same. Nobody is questioning that. What do you make of this study . This study normally we would not cover aster that was this preliminary. An abstract. Meaning it hasnt yet been submitted for, for publication to a journal. It has the not been reviewed yet by the scientific community. There are numbers in there that give me pause. For example the rate of autism they report is five times what the cdc reports. That makes me wonder are they overdieing anotion. What it showed was women who have high levels of folic acid, it, folate, b12, soon after delivery had kids who went on to develop autism at a higher rate than normal. Now this does not mean that taking too much b12 or folate causes autism this association. Needs more study. And the bottom line here is recommendation stays exactly the same. We do not want will tune misinterpret the headline. Should still be taking folic acid supplementation during pregnancy. Despite the headlines today this study is extremely preliminary and doesnt change the advice to take folic acid. Check with your doctor when taking supplementation or medication.

They can all be unfrozen this thursday or a week from this thursday. Imagine we thought we would still be fighting for ten more weeks. Ahead of the game . Ten weeks ahead of the game. Thats huge. Returning to his day job, texas senator ted cruz refused to utter trumps name for offer endorsement. There will be time for voters to make the determination who they will support.

A good bet it wasnt the new mayor of london who is muslim. Trump backtracked a little. Khan said that is not good enough. Sadiq khan won the election for mayor and by the biggest margin any major has ever had. That in which election in which his faith and history as a political activist and human rights lawyer forced him to battle off claims he was sympathetic to some extremist views.

There will always be exceptions, trump told the new york times. Sadiq khan told donald trump what to do with his exceptions. I think donald trump has ignorant views about islam. Not just about me. I dont want to be the exception to be allowed to go to america. This has become a tale of two city. Paris mayor, hopped the train to london, to congratulate its new mayor. What did she think of Donald Trumps ban all muslims proposition. Not much. Mr. Trump is so stupid, my god, my god. Not just stupid but wrong. You can be a muslim and be european. You can be a paris mayor, and london mayor and work closely together. Hope donald trump looks at the lessons that london set last thursday and recognizes possible to be western and muslim and to be friends with mayors of paris as well. Sadiq khan says the trump position plays into the hand of the extremists by playing into their narrative that the west is an unwelcoming place and is the enemy. And by the way, he has broken with tradition for foreign politicians. He says that if there is a contest between donald trump and Hillary Clinton, he not only backs
