Gluten is a protein found in wheat, barley, and rye. It is a common ingredient in many foods, but it can also be hiding in unexpected places.

For those with celiac disease or a gluten sensitivity, consuming gluten can lead to uncomfortable symptoms such as bloating, gas, and diarrhea. Here are 7 foods you didn’t know contain gluten:.

1. Soy Sauce

Soy sauce is a staple in many Asian dishes and is often used as a marinade or dipping sauce. However, traditional soy sauce contains wheat as a main ingredient.

There are gluten-free soy sauce alternatives available, so be sure to read the label before consuming.

2. Salad Dressing

Salad dressing may seem like a safe bet, but many store-bought dressings can contain gluten. Thickening agents and flavorings may contain wheat flour or other gluten-containing ingredients.

To be safe, try making your own salad dressing using simple ingredients like olive oil, vinegar, and herbs.

3. Candy

You may assume that candy is gluten-free, but many varieties contain gluten as an ingredient. For example, licorice and certain types of chocolate may contain wheat flour or barley malt.

Always check the label before indulging in your favorite sweet treat.

4. Beer

Beer is made from grains like barley and wheat, which means it often contains gluten. There are gluten-free beer options available, such as those made from sorghum or rice.

If you’re not sure if a beer contains gluten, be sure to ask your server or bartender.

5. Processed Meats

Many processed meats, such as sausages and hot dogs, may contain gluten as a filler or thickener. It’s important to read labels carefully and look for brands that explicitly state that they are gluten-free.

6. Instant Coffee

Instant coffee may contain traces of gluten due to manufacturing processes. While the amount of gluten is typically very small, those with celiac disease or severe gluten sensitivities may want to opt for freshly brewed coffee instead.

7. French Fries

While potatoes themselves are naturally gluten-free, French fries may contain gluten due to the frying process. Some restaurants use a shared fryer for both French fries and breaded items, which can lead to cross-contamination.

Always ask your server if the French fries are gluten-free.

Gluten can be hiding in many foods, so it’s important to read labels carefully and be vigilant about what you’re consuming.

For those with celiac disease or gluten sensitivities, a gluten-free diet is essential for maintaining overall health and wellbeing.
