Sonic Gluten-Free Options

Sonic Drive-In may look like they don’t offer gluten free items, but they are also considered one of the top fast food chains that offer gluten free options. In this article, we will go through Sonic’s gluten-free items and how to order them.

What is Gluten?

Before we go on their gluten free options list, let’s first understand why gluten should be avoided.

Gluten is a protein that is found in wheat, rye, and barley. It helps make dough elastic or chewy (which is why it’s often used in bread). People who are allergic to gluten may not be able to digest products with gluten, like buns, croutons, or breaded chicken items that are usually located at fast-food restaurants like Sonic America’s Drive-In.

Our body doesn’t produce enough enzymes to break down gluten-containing protein into small amino acids. If the body can’t absorb it, this triggers a chain reaction of inflammation and damage to cells in the body. The symptoms include diarrhea, bloating, fatigue, joint pain, brain fog, or headaches.

Sonic Gluten-Free Options

We’ve compiled the list of gluten free options at Sonic menu. All of these items do not contain wheat or gluten according to Sonic allergen menu guide.

Benefits of a Gluten-Free Diet

A lot of people have turned to a gluten-free diet in recent years, for various reasons. There are potential benefits to going gluten-free that you should be aware of:

  • Relief from symptoms of gluten intolerance or celiac disease: People with celiac disease or gluten intolerance can experience digestive problems, skin issues, fatigue, and other symptoms when they consume gluten. A gluten-free diet can help alleviate these symptoms and improve overall health.
  • Better digestive health: Even if you don’t have celiac disease or gluten intolerance, eating gluten can sometimes cause digestive discomfort. By eliminating gluten from your diet, you can improve your gut health, reduce bloating and gas, and promote regular bowel movements.
  • More nutrient intake: A gluten-free diet typically involves consuming more whole, unprocessed foods like fruits, vegetables, nuts, and lean proteins. These foods are often high in nutrients like fiber, vitamins, and minerals that can enhance overall health and wellness.
  • Improved energy levels: Some people feel more energetic and less fatigued after going gluten-free. This may be due to the fact that gluten can cause inflammation in certain individuals, leading to fatigue and other symptoms.
  • Weight loss: While a gluten-free diet alone is not a guaranteed weight loss solution, it can aid in weight loss when paired with a healthy lifestyle. Many gluten-free foods are naturally low in calories and fat, making them a suitable choice for those seeking to shed some pounds.

It’s essential to note that a gluten-free diet isn’t beneficial for everyone, and it’s not advisable to start it without consulting a healthcare professional. If you’re considering a gluten-free diet, it’s crucial to make sure you’re still getting all the necessary nutrients for optimal health.
