It seems like every day we hear another story about preservatives, additives, chemicals or toxins that have the potential to make us sick. Now, more than ever, people want to make the right choices so that they can have good health for themselves and their families. Jessica Alba wanted that too. When she was about to have her first baby, it was a wakeup call for her to find a life that could be summed up in two words: Pure and simple. The actress, entrepreneur and mom writes about all of this in her new book, The Honest Life.

New York City’s Cortney and Bob Novogratz are the home design world’s go-to couple for their signature style of mixing modern and vintage elements. In other words, they know how to reuse stuff and make it look cool. On top of that, they have seven kids!

For six million children, everyday food items can be dangerous, even deadly, because they are allergic to things like peanuts, milk, eggs or wheat. In the cover story of a recent New York Times Magazine article, writer Melanie Thernstrom from San Francisco introduces us to Dr. Kari Nadeau, an associate professor of allergies and immunology at Stanford’s Lucile Packard Children’s Hospital. Dr. Kari Nadeau is conducting an experimental trial that may offer these families something they haven’t had in the past: hope.

“We’re giving back the food that people are allergic to.” -Dr. Kari Nadeau

@katiecouric thanks for the informative session on allergies!! My 12 yr old would love to be able to eat a pb&j w/I dying!!
