Is Gluten-Free Lower in Carbs?

Posted by Izhar Groner on

The question of whether a gluten-free diet is lower in carbohydrates has gained significant attention in recent years. With the growing popularity of gluten-free diets, it's essential to understand the relationship between gluten and carbohydrates and how it impacts our nutritional choices. This article delves into the science behind gluten and carbs, explores the differences between gluten-free and gluten-containing foods, and provides insight into how these dietary choices can affect your carbohydrate intake.

Defining Gluten and Carbohydrates

Before we delve into the question at hand, it's crucial to define what gluten and carbohydrates are.

Gluten: Gluten is a protein found in wheat, barley, rye, and their derivatives. It is responsible for the elasticity of dough and gives bread and other baked goods their texture. Gluten plays a significant role in the baking industry, but it can cause health issues for individuals with celiac disease or non-celiac gluten sensitivity.

Carbohydrates: Carbohydrates are one of the three macronutrients, alongside fats and proteins, and are a primary source of energy for the body. Carbohydrates are classified into two categories: simple carbohydrates (sugars) and complex carbohydrates (starches and fibers). While sugars are readily digestible and provide quick energy, starches and fibers take longer to break down and provide sustained energy.

Gluten and Carbohydrates in Gluten-Containing Foods

Gluten-containing foods like bread, pasta, and cereals are well-known for their carbohydrate content. These foods are rich in complex carbohydrates, primarily in the form of starch. Starch is a polysaccharide composed of long chains of glucose molecules and is a significant source of energy for humans.

When we ask whether gluten-containing foods are high in carbohydrates, the answer is a resounding yes. The carbohydrate content in wheat-based products is significant, making them an integral part of a typical Western diet. However, it's important to note that gluten itself is not a carbohydrate; it's a protein. Therefore, gluten-containing foods are high in carbohydrates not because of gluten but because of the starchy grains used in their preparation.

The Gluten-Free Diet and Carbohydrates

Now, let's address the central question: Is a gluten-free diet lower in carbohydrates?

The answer depends on the choices individuals make within a gluten-free diet. Gluten-free foods are those that do not contain wheat, barley, rye, or their derivatives, which eliminates many traditional carbohydrate-rich staples from the diet. However, gluten-free alternatives to these staples are available, and their carbohydrate content may vary.

  1. Gluten-Free Grains and Carbohydrates

People on a gluten-free diet often turn to alternative grains such as rice, corn, quinoa, and oats. These grains are naturally gluten-free and can be used to create a variety of gluten-free products like bread, pasta, and baked goods. While these grains are indeed gluten-free, they still contain carbohydrates in the form of starch.

So, it's crucial to understand that a gluten-free diet does not inherently mean a low-carb diet. The carbohydrate content of gluten-free grains is similar to that of their gluten-containing counterparts. Therefore, if individuals consume gluten-free versions of bread, pasta, and cereals, they will still be obtaining carbohydrates, although the type of carbohydrate may differ.

  1. Gluten-Free Processed Foods

One area where individuals need to exercise caution is with gluten-free processed foods. Many commercially available gluten-free products, such as cookies, cakes, and snacks, may have added sugars and starches to improve taste and texture. This can lead to an increased carbohydrate intake in individuals following a gluten-free diet, potentially negating any perceived carb-reduction benefits.

  1. Whole Foods on a Gluten-Free Diet

For those who are concerned about carbohydrate intake on a gluten-free diet, the key is to focus on whole, unprocessed foods, including wholesome snacks like those of Plantraw®. Fresh fruits and vegetables, lean proteins, nuts, and seeds are naturally gluten-free and generally lower in carbohydrates than processed gluten-free alternatives. Choosing these whole foods can help individuals maintain a healthier balance of nutrients and reduce their carbohydrate intake.

Carbohydrate Content in Gluten-Free vs. Gluten-Containing Foods

To further explore the difference in carbohydrate content between gluten-free and gluten-containing foods, let's compare some common items:

  1. Bread:

    • Gluten-Containing: A slice of whole wheat bread typically contains around 12-14 grams of carbohydrates.
    • Gluten-Free: A slice of gluten-free bread can vary widely in carbohydrate content but is often similar to wheat-based bread.
  2. Pasta:

    • Gluten-Containing: A 2-ounce serving of regular wheat pasta has approximately 42 grams of carbohydrates.
    • Gluten-Free: A 2-ounce serving of gluten-free pasta, made from rice or corn, typically contains a similar amount of carbohydrates.
  3. Cereals:

    • Gluten-Containing: A cup of regular breakfast cereal can contain anywhere from 20 to 60 grams of carbohydrates, depending on the brand and type.
    • Gluten-Free: Gluten-free cereals may have a comparable carbohydrate content to their gluten-containing counterparts.

These examples illustrate that the carbohydrate content in gluten-free alternatives is often similar to that of gluten-containing foods. Therefore, individuals who choose gluten-free options are not necessarily reducing their carbohydrate intake.

Balancing a Gluten-Free Diet

For those with celiac disease or gluten sensitivity, a gluten-free diet is a medical necessity, not a choice. However, it's crucial to approach this diet with a balanced perspective, ensuring that nutrient needs are met while managing carbohydrate intake.

  1. Read Food Labels: When opting for gluten-free processed foods, read labels carefully to understand their carbohydrate and sugar content. Look for products with lower sugar and higher fiber content to make healthier choices.

  2. Opt for Whole Foods: Emphasize whole, unprocessed foods in your gluten-free diet. These foods are naturally lower in carbohydrates and provide essential nutrients.

  3. Portion Control: Be mindful of portion sizes, especially when consuming gluten-free grains like rice and quinoa. This can help you manage your carbohydrate intake effectively.

  4. Consult a Dietitian: If you're unsure about managing your carbohydrate intake on a gluten-free diet, consult a registered dietitian or healthcare professional for personalized guidance.


In answering the question, "Is gluten-free lower in carbs?" it's essential to recognize that the presence or absence of gluten does not determine the carbohydrate content of a food. Gluten-free foods, while devoid of gluten-containing grains, can still be rich in carbohydrates, especially when processed or made with alternative grains.

The key to managing carbohydrate intake on a gluten-free diet is to make informed choices, prioritize whole, unprocessed foods, and be mindful of portion sizes. Whether you follow a gluten-free or gluten-containing diet, balancing your nutrient intake and maintaining a healthy lifestyle should be your primary focus.
