A gluten-free diet is absolutely necessary for those diagnosed with celiac disease.  In Canada, that’s about 35,000 people.  Yet over 4 million Canadians are going gluten-free because they believe it’s better for them.  But is it?

Let’s compare a loaf of bread from Udi’s, a gluten-free food company, and a loaf of Wonder bread.  The Udi’s bread is more than twice as expensive, has more calories, more sodium, more sugar, more fat, and less fiber than the Wonder bread, and that’s the white bread.

Udi’s has all kinds of celebrity endorsements and makes vague, but unproven, health claims regarding autism and ADHD.
