Gluten's Impact On Keto: What You Need To Know

Gluten is a protein found in wheat, barley, and rye that acts as a binding and extending agent in food. It is not necessary in our diets, and so there are no issues with avoiding it. However, for those on a keto diet, gluten can be problematic as it is often found in carbohydrate-rich foods, which are restricted on a keto diet. While a keto diet is not inherently gluten-free, it is naturally very low in gluten as it restricts foods that contain gluten, such as bread, pasta, and baked goods. For those with gluten intolerance or celiac disease, it is important to avoid gluten to prevent symptoms such as diarrhea, bloating, and fatigue, as well as long-term complications. Even for those without celiac disease, a gluten-free diet may provide benefits such as improved gut health and reduced inflammation. Therefore, it is important to understand the role of gluten in a keto diet and how it can impact health.

Gluten-free foods are not always low-carb

Gluten is a protein found in wheat, barley, and rye, and it acts as a binding and extending agent in food. It is added to products to retain moisture, improve texture, and enhance flavour. Gluten-free products often replace wheat with other thickeners and binders that are void of gluten but high in carbs, such as corn, rice, tapioca, or potato starch. These highly processed foods can cause insulin spikes and are therefore not suitable for a keto diet.

Gluten-free substitutes can be found in the form of almond flour or coconut flour, which are usually delicious and keto-friendly. There are also gluten-free bread, pasta, cakes, etc. that are compatible with low-carb diets like keto, but they can be hard to find.

It is important to note that gluten is not necessary in our diets, and there are no issues with avoiding it. However, if you have coeliac disease or other gluten sensitivities, it is important to follow the advice of your medical professional.

Gluten-free products can be high in sugar and carbs

Gluten-free products are not always low in carbohydrates. Carbohydrates and gluten are two different things. While gluten is a protein compound found in grains, carbohydrates consist of sugar.

Gluten-free products are often made with corn, rice, tapioca, or potato starch. These ingredients are loaded with a high concentration of carbs. These highly processed foods will spike your insulin levels and then bring your sugar crashing down after an hour or so.

A low-carb diet aims to keep your blood sugar levels stable, which is beneficial for those who are insulin resistant. However, gluten-free products can be high in sugar and other carbohydrates that can kick someone out of ketosis.

Therefore, it is important to read labels carefully and be selective about the foods you include in your diet. Just because a product is gluten-free does not mean it is automatically keto-friendly.

Additionally, gluten-free flours used in baking can be made from ingredients like rice flour, tapioca starch, cassava, and corn/corn starch. These flours have a high glycemic index, which means they can cause a rapid increase in insulin levels and excess fat storage.

So, while a gluten-free diet may be medically necessary for those with celiac disease or gluten intolerance, it is not always a healthier option when it comes to sugar and carb content.

Gluten is a binding agent that adds structure and texture to food

Gluten is formed when flours containing two other grain-based proteins, gliadin and glutenin, are mixed with water. Many grains contain gluten, including wheat, spelt, barley, rye, kamut, wheat berries, and triticale. As a result, products derived from these grains, such as bread, pasta, bagels, pizza, and muffins, also contain gluten.

In addition to its role as a binding agent, gluten is also added to packaged foods as a flavour enhancer and texturizer. This makes it challenging for those who need to avoid gluten, such as people with celiac disease or non-celiac gluten sensitivity, to completely eliminate it from their diets.

While gluten is not inherently bad, some people may experience negative health effects from consuming it. For those with celiac disease, ingesting gluten triggers an immune response that attacks the small intestine, leading to symptoms like diarrhoea, bloating, gas, and fatigue. Even for those without celiac disease, gluten can cause gastrointestinal issues similar to irritable bowel syndrome (IBS).

Furthermore, gluten-free does not always mean low-carb or keto-friendly. Many gluten-free products are made with alternative starches like rice flour, tapioca starch, or corn starch, which are high in carbohydrates and can spike insulin levels. Therefore, while a keto diet naturally reduces gluten intake due to the restriction of carbohydrate-rich foods, it is important to read labels carefully to ensure that gluten-free products are also low in carbs.

Gluten can be replaced by other thickeners and binders

Gluten is a group of proteins found in wheat, barley, rye, and other grains. It is added to many packaged foods as a flavour enhancer, texturizer, and binder. It is also used as a meat replacement ingredient in vegan and vegetarian foods.

Gluten-free products often contain other thickeners and binders that are high in carbohydrates, which are not suitable for a keto diet. These include corn, rice, tapioca, or potato starch. These highly processed foods can cause a spike in insulin levels, which is not ideal for those who are insulin-resistant.

However, there are gluten-free substitutes that are compatible with keto. These include almond flour and coconut flour, which are usually delicious and keto-friendly. There are also some brands of gluten-free bread that are rich in healthy fats and proteins and can be included in a keto diet.

It is important to note that gluten-free does not always mean low-carb or healthy. Some gluten-free flours, such as rice flour, tapioca starch, cassava, and corn starch, have a high GI and can cause a spike in insulin levels.

Therefore, it is essential to carefully read food labels and choose gluten-free products that are also low in carbohydrates to ensure they fit within a keto diet.

Gluten-free diets may not be healthier

Gluten-free diets are often associated with health and wellness, but they may not always be healthier. While gluten-containing foods are not especially nutrient-dense, gluten-free diets may not be more nutritious and can even lead to nutritional deficiencies.

Gluten-free diets are often based on gluten-free flours, such as rice flour, tapioca starch, cassava, and corn/corn starch. These flours are high on the glycemic index, meaning they can cause a spike in insulin levels, potentially leading to excess fat storage. Additionally, gluten-free diets can be socially and financially burdensome, and there is limited research on their long-term effects.

Furthermore, gluten-free diets are not always low in carbohydrates. Many gluten-free products, such as bread, pasta, and cookies, are made with gluten-free flours but still contain significant amounts of carbohydrates. These products can cause a similar increase in blood sugar levels as gluten-containing foods.

For individuals without gluten intolerance or celiac disease, there may be limited benefits to following a gluten-free diet. In fact, one study found that healthy individuals who eliminated carbohydrates with gluten from their diets for a month experienced a decrease in healthy gut bacteria and an increase in unhealthy bacteria.

Therefore, while gluten-free diets can be beneficial for those with gluten intolerance or certain medical conditions, they may not be inherently healthier for the general population. It is always important to consult with a healthcare professional before making any significant dietary changes.
