The Grasses -
Many people want to use wheat, barley, rye, and oat grass (not the seed) as a supplement in the diet.  Technically, these do not contain gluten as they are the grass part of the plant.  However; it is recommended that these be avoided to prevent the possibility of cross contamination.
Alcoholic Beverages that contain gluten-
Beer
Malted beverages
Grain based spirits (many claim that distillation removes gluten…Gluten Free Society recommends avoidance regardless)
Non Edible Items That May Contain Gluten (Read Your Labels)-
Stamps & envelopes
Toothpaste

Detergents

Is There Gluten in Dairy?
Research has identified that gluten from mother’s milk passes into the dairy of humans.  A majority of gluten sensitive individuals do not tolerate milk or dairy based foods.  The staple diet for commercial dairy cows is grain.  Whether or not glutens from feeding cows grain crosses into dairy is still in question and has not been adequately studied.    That being said, common sense of the obvious should supersede the decision to use dairy.  Gluten Free Society recommends only dairy that comes directly from pasture fed cows if any at all.  For more in depth information on this topic, please listen to the following 2 part interview between Dr. Peter Osborne and Dr. Rodney Ford:
Part 1
Part 2
****Note – their is no such thing as a complete comprehensive list of food items that contain gluten.  Manufacturers regularly change their ingredients, mislabel, have product recalls, etc.  This is why Gluten Free Society’s stance is to avoid processed and packaged foods as much as possible as well as to avoid eating out as much as possible.  You cannot control the mistakes or ethical considerations of others.
