Experts Change Advice on Kids' Allergies - washingtonpost.com:

Breast-feeding helps prevent babies' allergies, but there's no good evidence for avoiding certain foods during pregnancy, using soy formula or delaying introduction of solid foods beyond six months. That's the word from the American Academy of Pediatrics, which is updating earlier suggestions that may have made some parents feel like they weren't doing enough to prevent food allergies, asthma and allergic rashes.

In August 2000, the doctors group advised mothers of infants with a family history of allergies to avoid cow's milk, eggs, fish, peanuts and tree nuts while breast-feeding.

That advice, along with a recommended schedule for introducing certain risky foods, left some moms and dads blaming themselves if their children went on to develop allergies.

"They say, 'I shouldn't have had milk in my coffee,'" said Dr. Scott Sicherer of the Mount Sinai School of Medicine's Jaffe Food Allergy Institute in New York. "I've been saying, 'We don't really have evidence that it causes a problem. Don't be on a guilt trip about it.'"

Sicherer helped write the new guidance report for pediatricians, published in the January issue of the journal Pediatrics. Earlier advice about restricting certain foods from moms' and babies' diets has been tossed out and the only surefire advice remaining is to breast-feed.

Kinda goes hand-in-hand with the recent revelation that there's no such thing as the "Mozart Effect", at least as far as IQ scores go.

Of course, there's more to academic and professional success besides the mere IQ score.  Whether extended/complex music in early chlidhood impacts concentration skills or long-term memory, neither of which are covered in the typical Mensa thingy but are critical to success in our society, is not really addressed by the hype.  The hassle of not having an objective criteria for success we can all agree on...
