Below is a reprint from a question Melissa answered in Better Nutrition magazine.
Q: What is the most common mistake people make on the gluten-free diet?
A: For people who are just beginning the gluten-free diet as well as those who have been on the diet a long time, the biggest mistake they make is over-relying on manufactured processed foods instead of eating naturally gluten-free whole foods such as vegetables and fruits.
Highly processed “gluten-free” food products set people up for health problems in three different ways. The first way is, ironically, by those products sometimes being contaminated with unwanted gluten. Even though gluten-free grains and and flours are naturally gluten free, these foods are often processed in the same facilities – and with the same equipment – as the gluten grains wheat, rye, and barley, where they can inadvertently pick up gluten.
