Gluten-Free Keto: Foods To Eat And Avoid

The ketogenic diet is a high-fat, low-carbohydrate diet that aims to put the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. While a keto diet is often gluten-free, as it typically involves avoiding wheat and other grains, it is not always the case. Some keto-friendly foods, such as soy sauce, do contain gluten. On the other hand, gluten-free foods are not always keto-friendly, as they may contain high levels of carbohydrates. For those with celiac disease or gluten intolerance, it is essential to avoid gluten, but for others, the decision to avoid gluten may be a choice to improve overall health. Understanding the differences between a keto and gluten-free diet is crucial for those considering either dietary approach.

Gluten-free foods aren't always keto-friendly, and vice versa

Gluten is a mixture of proteins found in wheat, barley, and rye. It gives bread its springiness and provides structure and texture to many bread products. Gluten is also commonly found in crackers, cakes, pastries, pasta, bagels, pizza, muffins, and a vast array of other refined carbs.

A gluten-free diet is typically followed by people with celiac disease, a condition where the body's immune system attacks healthy tissue when gluten is consumed, leading to a range of health consequences. A gluten-free diet is also beneficial for those with a wheat allergy or non-celiac gluten sensitivity, which can cause gastrointestinal issues and irritable bowel syndrome.

The keto diet, short for ketogenic, is a high-fat, low-carbohydrate diet. It involves drastically cutting down on carbohydrates and replacing them with healthy fats and proteins. When the body enters a state of ketosis, it starts breaking down stored fat to use as energy. A keto diet usually involves eating fewer than 20 to 50 grams of carbs per day.

Gluten-free doesn't always mean keto-friendly

While a keto diet often tends to be gluten-free as it avoids wheat and other grains, not all gluten-free foods are keto-friendly. Gluten-free products often contain too many carbohydrates to be considered ketogenic. For example, gluten-free bread, pasta, and cookies are made from refined carbs and gluten-free flours like corn, potato starch, rice flour, or tapioca, which are not keto-friendly.

Keto-friendly doesn't always mean gluten-free

On the other hand, some keto-friendly foods may contain gluten. For instance, soy sauce, which is commonly used as a flavour enhancer, contains gluten. Processed meats, soups, stocks, alcohol, and dressings may also contain gluten, so it's important to read labels carefully.

Combining the keto and gluten-free diets

If you're considering combining the keto and gluten-free diets, it's important to understand their differences and how they relate to each other. While a keto diet is often naturally low in gluten, it's not always gluten-free, and vice versa. To follow both diets, focus on whole foods like vegetables, meat, fish, nuts, healthy fats, and eggs, and avoid gluten-containing grains and highly processed gluten-free products.

Gluten is found in wheat, barley, rye, and other grains

Gluten is a protein found in grains such as wheat, barley, rye, and spelt. It is formed when flours containing the proteins gliadin and glutenin are mixed with water. Gluten provides food with structure and chewiness.

Wheat is the primary source of gluten, and it is found in a variety of wheat-based products, including bread, pasta, bagels, pizza, muffins, and other refined carbs. Gluten is also commonly found in barley and rye, as well as other grains such as kamut, wheat berries, and triticale. These grains are often used in baked goods, crackers, and cereals, which means that gluten can be found in a wide range of processed and packaged foods.

In addition to naturally occurring gluten, manufacturers often add gluten to packaged foods as a flavour enhancer, texturizer, and binder. This makes it challenging for those with gluten intolerance or sensitivity to completely avoid gluten in their diets.

For those with celiac disease, a wheat allergy, or non-celiac gluten sensitivity, it is essential to follow a gluten-free diet. Celiac disease is an autoimmune condition where the ingestion of gluten leads to intestinal inflammation, intestinal permeability, and nutrient deficiencies. Wheat allergy involves an allergic reaction to wheat proteins, which can cause life-threatening symptoms. Non-celiac gluten sensitivity is a controversial diagnosis, but it is believed to be related to changes in intestinal permeability caused by gluten or other components of wheat.

While a gluten-free diet is crucial for those with gluten-related disorders, it is important to note that gluten-free does not always mean healthier. Gluten-free products are often highly processed and may contain more sugar, fat, and refined carbohydrates than their gluten-containing counterparts.

Gluten-free foods are often highly processed

Tapioca starch, for example, is high in carbs but has hardly any protein, fibre, vitamins or minerals. When used alone, as many gluten-free food makers do, these flours and starches make seemingly healthy gluten-free foods unhealthy, and full of empty calories. The empty calories in tapioca and the other starchy flours will likely spike your blood sugar—sometimes even more than refined sugar! High insulin levels follow, which blocks the mobilisation of fat and encourages inflammation, so you will actually gain weight, instead of losing it.

In addition, highly-processed gluten-free diets that are high in refined carbohydrates are often deficient in important nutrients such as iron, zinc, vitamin D, and protein.

However, it is possible to eat a healthy gluten-free diet. Most whole, unprocessed foods are gluten-free, including fruits, vegetables, legumes, certain whole grains, dairy products, and oils, as well as fresh meat, fish, and poultry.

Gluten-free diets are recommended for people with autoimmune diseases

Gluten is a protein found in grains such as wheat, barley, rye, spelt, barley, kamut, wheat berries, and triticale. It is also added to many processed foods as a flavour enhancer, texturizer, and binder.

For people with celiac disease, a gluten-free diet is a medical necessity. Celiac disease is an autoimmune condition affecting less than 1% of the global population. When someone with celiac disease consumes gluten, their immune system attacks healthy tissue, leading to intestinal inflammation, intestinal permeability (leaky gut), and subsequent nutrient deficiencies. A gluten-free diet is therefore vital for people with celiac disease to prevent intestinal damage and promote healing.

However, the benefits of a gluten-free diet extend beyond those with celiac disease. Many people with non-celiac gluten sensitivity experience gastrointestinal issues and other symptoms such as fatigue and rash when consuming gluten. Additionally, a gluten-free diet may offer relief for those with irritable bowel syndrome (IBS), type 1 diabetes, and other autoimmune conditions such as thyroid disease and rheumatoid arthritis.

Gluten has been linked to increased intestinal permeability, also known as leaky gut. When gluten is consumed, it triggers the release of zonulin, a chemical that signals the tight junctions of the intestinal wall to open up, allowing microbes, toxins, proteins, and partially digested food particles to pass into the bloodstream. This can lead to chronic inflammation as the immune system continuously creates inflammation in response to these foreign substances.

Furthermore, gluten poses a risk for those with autoimmunity due to molecular mimicry, where the body mistakes gluten for its own tissues and attacks them. This is particularly true for those with autoimmune thyroid disease, as gluten proteins are structurally similar to thyroid tissues.

Therefore, a gluten-free diet is recommended not only for people with celiac disease but also for those with other autoimmune conditions or non-celiac gluten sensitivity. While a gluten-free diet may be challenging and expensive, it can provide significant relief from symptoms and improve overall health for many individuals.

Gluten-containing foods are not especially nutrient-dense

Gluten-containing grains tend to be less nutrient-dense than other food options. For example, whole grains like wheat and rye are a source of fibre and some B vitamins, but they are not a good source of essential nutrients like vitamins A, C, and E, or minerals like calcium and iron. In contrast, replacing gluten-containing grains with vegetables, nuts, meat, fish, and fruits can increase the variety of vitamins and minerals in your diet.

Additionally, gluten-free diets can be beneficial for people with certain medical conditions. For instance, individuals with celiac disease must avoid gluten completely, as it triggers an autoimmune response that attacks the small intestine, leading to inflammation and nutrient deficiencies. A gluten-free diet is the primary treatment for celiac disease and can help manage symptoms and prevent further damage.

It is important to note that gluten-free diets are not inherently healthier. Gluten-free processed foods, such as cookies, crackers, and bread, are often made with refined grains and additives, resulting in a less nutritious option. Therefore, it is crucial to focus on whole, unprocessed foods, whether gluten-free or not, to ensure a nutritious diet.

Furthermore, while gluten-containing foods are not necessary for a healthy diet, they may provide some benefits for those who can tolerate them. Whole grains, including gluten-containing ones, have been linked to improved health outcomes. Research suggests that consuming 2-3 servings of whole grains daily can lower the risk of heart disease, type 2 diabetes, and stroke. Additionally, gluten may act as a prebiotic, feeding the good bacteria in the gut and promoting a healthy digestive system.

In conclusion, while gluten-containing foods may provide some nutritional benefits for those who can tolerate them, they are not essential to a healthy diet. For those with medical conditions like celiac disease, a gluten-free diet is necessary and can bring significant health improvements. Replacing gluten-containing grains with more nutrient-dense options can enhance the overall nutritional quality of your diet.
