Now urban legends are urban folklore that was created by stories weaved together and circulated around until most people have accepted them as truths. There are different kinds of urban myths and covers a wide range of subject. It’s not impossible to find that even diseases have their own folklore. A celiac disease urban legend revolves around teabags containing gluten which can trigger the disease.
For those who do not know, celiac disease is a condition where the small intestines get inflamed due to the consumption of food containing gluten. Gluten is a protein commonly found in food made from wheat, barley, and rye. So such foods like bread, pizza, and pasta can contain gluten. The condition can be terrible in the long run. The inflammation that the disease causes in the intestines prevents the body to absorb the nutrients that it needs. So the end result would be malnutrition. Malnutrition itself can then cause more ailments.
I don’t actually know where and when it started, but stories have already circulated that some makers of tea uses tea bags made from gluten. This is obviously bad for tea drinkers that have contracted celiac disease. Word went out and people with the disease now started to avoid tea just because of the stories or are selective of the tea brands that they buy.
Reinforcing the stories is the fact that tea manufacturers began labeling their products as using only gluten-free tea bags. This, of course, is a reaction from the stories which probably resulted in tea sales going down. That’s the problem with urban myths, despite how absurd they might sound, people will tend to be wary since they would treat stories coming from credible sources as truth. The effects can sometimes be quite devastating.
Now, there has not been a solid shred of proof that manufacturers indeed used gluten as an ingredient for making their teabags. Some say that making tea bags with gluten does not make sense at all since gluten can be dissolved with water. Although, there is research that indicates that gluten has poor water-solubility properties. But still, stories circulated.
Tea in itself does not contain gluten. It contains caffeine and other antioxidants but definitely not gluten. However, the tea brands that are available in the market today are often a blend of other ingredients. The reason for blending different kinds of tea and other stuff is to develop a unique taste. There are times that barley is added to tea blends to enhance taste and to offer something different. But barley contains gluten. Maybe, a tea brand that contains barley was consumed by someone with celiac disease. The symptoms recurred and that person might have generalized that the tea was the cause not analyzing it more closely.
That can be the start of the urban myth of the teabag. I am not aware of any tea blends, today or in the past, which uses barley or even wheat as part of the ingredients. In the same way, I haven’t read any conclusive study which defunct this urban legend once and for all.
Personally, I would believe the fact that protein-based or gluten-based tea bags is not a commercial viability. I would choose to believe that this is indeed a celiac disease urban legend. However, for you who chose to be cautious, there are numerous tea brands today that claim to be gluten-free. With regard to choices, you won’t be restricted. You can continue enjoying your tea.
