Eat Organically

When it comes to eating organically, Sophie says you don't need to run out and replace everything in your fridge at once. "The first thing I say to people is to think about what you eat the most of," Sophie says.

Families with young children consume a lot of baby food, so Sophie suggests starting there. "I am recommending organic baby food because babies are much more vulnerable to the effects of pesticides, and there's a lot of pesticide residue on all food," Sophie says.

Julia says she feeds her youngest son, Henry, organic baby food. "I make some of my own, I'm happy to say ," she says. "He's doing great."
