“That Bites!” is a documentary about food allergies and living with food allergies by a 12-year old kid in Chicago. Good for him. He’s funded, but I would love to see him get a ton of money and go big with this thing. Our son has a bunch of food allergies and it’s scary that he could be killed by a bit of peanut cross-contamination. Food is so central to so many activities, and his inability to casually participate — or, say, to get on a plane without our worrying — is profoundly saddening to me. Broader understanding of food allergies, their seriousness, and how to minimize risk to others in environments like restaurants is critical.
