What is Gluten? 

Gluten is a common term for the proteins found in wheat, rye, barley, triticale, malt, and brewer’s yeast.1 It is what helps maintain the shape and texture of foods made with these grains. The list looks simple enough, but we have not yet considered the various products made from these grains that are then used in various foods. This can make it difficult to really know which consumables contain gluten. 

For example, products like semolina, farina, spelt, farro, bulgar, emmer, and more, are all products made from wheat. If you see one on a food item’s ingredient list, you may not immediately know that it contains gluten.

What is the Problem with Consuming Gluten?

Consuming gluten typically isn’t a problem unless you have a sensitivity to or intolerance for it. People diagnosed with Celiac Disease experience the more serious side-effects because the intake of gluten actually causes damage to the small intestine. Not only does this hinder nutrient absorption, it can also result in symptoms like weight loss and diarrhea.2 For these reasons, malnutrition is a serious concern for individuals with this condition.  

Non-celiac gluten sensitivity essentially means that, even though a person tests negative for Celiac Disease and negative for a wheat allergy, they still experience some of the milder side-effects. Typically, this means they may experience some intestinal symptoms, headaches, fatigue, and joint pain if they consume gluten.2 

Busting the Myths About Gluten

Gluten-Free Diets Aid Weight LossMYTH 

How surprised would you be to learn that the opposite can actually be true? Gluten-free foods can contribute to weight gain because food manufacturers will often add fat and sugar to help recreate the qualities that gluten gives to food.3 In fact, there is no evidence that supports the idea that gluten-free foods can help someone lose weight.3   

The reason gluten-free diets are perceived as beneficial for weight loss probably comes from the fact that going “gluten free” can simply mean sticking to unprocessed foods. For example, avoiding glutinous foods (like cake, pasta, etc.) can mean a lower daily calorie count which is potentially what helps gluten free dieters lose weight. 

Gluten-Free Labels Mean Zero Gluten Content – MYTH 

Research has determined that there is a safe threshold in terms of gluten consumption. So, if a food is labeled as “gluten free,” what that really means is that it contains less than 20 parts per million of gluten.4 Okay, but what does that even mean? We rarely quantify things this way. Parts per million refers to how much gluten there is in relation to all the other ingredients. This is not a fixed number. Some foods have a little more and some have a little less.  

Each low-gluten food item adds to your overall daily intake. This means that if you consume too many “gluten-free” foods, you can accidentally consume more than the safe amount. Individuals with Celiac Disease are advised to consume no more than 10-50 milligrams per day.4  

Gluten-Free Diets are Easy to Follow – MYTH 

Following a gluten-free diet is actually pretty tough to adhere to, and if you don’t pay attention to what you’re eating (or if you stick to the same foods every single day), you may put yourself at risk for nutrient deficiencies. Not to mention that gluten-free foods typically aren’t enriched with the nutrients you’re already missing by avoiding gluten-containing foods.3 

According to an article by the Gluten Intolerance Group, some of the most common nutrients that are difficult to obtain on a gluten-free diet include: 

  • Thiamin 
  • Riboflavin 
  • Niacin 
  • Folate 
  • Iron 
  • Calcium 
  • Vitamin D 
  • Magnesium 
  • Fiber 
  • Zinc 

Which Foods You Should Avoid

If you need to go gluten-free, Healthline explains that the easiest way to avoid gluten is to eat unprocessed, single-ingredient foods. This means you should avoid foods like bread, pasta, cereal, cookies, muffins, pizza, crackers, and certain beverages like beer. You should also avoid foods made or topped with soy sauce, teriyaki sauce, hoisin sauce, certain broths or marinades, and even some salad dressings.1  

If you are going to consume grains, you are encouraged to stick to foods like quinoa, rice, buckwheat, tapioca, corn, and gluten-free oats.1 To be extra-safe, check the packaging for a “gluten-free” label on these items because many foods that are naturally gluten-free (like oats) may still be contaminated with gluten because they are processed or packaged in the same facility as gluten-containing products.  

The lists go on for both the do’s and don’ts of gluten-friendly dieting, so be sure to check with a reputable source for a more complete list of foods.
