Does a gluten-free diet help control blood sugar levels? Explaining the effects on diabetes
What is gluten?
The nature of gluten and foods that contain it
Gluten is a type of protein found in wheat, barley, rye, etc. Gluten is a sticky substance that is formed when water is added to flour and kneaded. This property gives foods such as bread and pasta their chewy texture and shape . Typical foods that contain a lot of gluten include the following:
- bread
- Pasta
- Pizza
- Cake
- Cookies
- ramen
- Udon
- Gyoza wrappers
- Hamburger buns
- Sauces (soy sauce, Worcestershire sauce, dressing, etc.)
As you can see, gluten is found in many foods that are an essential part of our diet, but for some people, gluten can cause health problems .
Gluten intolerance and its symptoms
Gluten intolerance is a condition in which consuming gluten causes a variety of symptoms in the body. Also known as celiac disease, it is a type of autoimmune disease that is different from wheat allergy. When a person with gluten intolerance ingests gluten, the mucous membrane of the small intestine is damaged, inhibiting nutrient absorption. As a result, a wide range of symptoms can appear, including:
| Symptom types | Specific symptoms |
|---|---|
| digestive system | Diarrhea, constipation, abdominal pain, abdominal distension, vomiting, etc. |
| skin | Eczema, rash, itching, etc. |
| Mental and nervous system | Headaches, depression, irritability, difficulty concentrating, etc. |
| whole body | Fatigue, weight loss, anemia, osteoporosis, etc. |
It is said that approximately 1% of the world's population suffers from gluten intolerance. Symptoms vary from person to person, but the only treatment is a diet that avoids gluten , and it is important to avoid wheat products. If you suspect that gluten is causing health problems, we recommend consulting a doctor for a proper diagnosis.
The relationship between gluten and blood sugar levels
The effect of gluten intake on blood sugar levels
Consuming foods that are high in gluten can affect blood sugar levels . This is thought to be because gluten causes an inflammatory response and increases insulin resistance. Gluten may also disrupt the intestinal environment, adversely affecting blood sugar control. Below, we will look at each of these mechanisms in more detail.
Gluten-induced inflammation and insulin resistance
Gluten is a substance that can cause an inflammatory response in the body. Chronic inflammation can lead to insulin resistance, which weakens the action of insulin. Insulin is a hormone that lowers blood sugar levels, but when its effect is weakened, hyperglycemia tends to persist . It is believed that gluten intake is involved in raising blood sugar levels through this mechanism.
Disturbances in the intestinal environment and blood sugar control
Gluten can also affect the intestinal environment. Ingesting gluten can disrupt the balance of the intestinal flora, leading to an increase in harmful bacteria . An imbalance in the intestinal environment can lead to a decrease in digestive and absorptive function and increased inflammation. As a result, insulin may become less effective, making blood sugar control more difficult . In this way, it has been pointed out that gluten may be directly or indirectly involved in regulating blood sugar levels.
Gluten-free diet improves blood sugar
Considering the effects of gluten on blood sugar levels as described above, a gluten-free diet that avoids gluten may be effective in blood sugar management . In fact, several studies have suggested the usefulness of a gluten-free diet. However, it is important to note that there are individual differences, so it may not be effective for everyone.
Research shows the effectiveness of gluten-free diets
A study published in 2018 examined the effects of a gluten-free diet in patients with type 2 diabetes. The results showed that the group that followed a gluten-free diet for 12 weeks showed a significant improvement in HbA1c, an indicator of blood sugar control . Another study also reported a positive correlation between gluten intake and the risk of type 2 diabetes. These findings suggest that a gluten-free diet may contribute to blood sugar control.
There are individual differences and it may not be effective for everyone
However, it's important to remember that the effects of a gluten-free diet vary from person to person . People with a high sensitivity to gluten, such as those with gluten intolerance or celiac disease, may be able to expect greater improvement. On the other hand, people who are not susceptible to gluten to begin with are likely to see limited changes in blood sugar levels as a result of going gluten-free. Also, some gluten-free foods contain high amounts of carbohydrates and fats , so care must be taken when choosing. It's important not only to avoid gluten, but also to strive for a balanced diet overall.
The relationship between gluten-free diets and diabetes
Much research has been conducted in recent years on the relationship between gluten and diabetes. In particular, attention has been focused on the effects of gluten on type 1 and type 2 diabetes, as well as the effectiveness of a gluten-free diet. Here, we will take a closer look at the relationship between diabetes and gluten, by type .
The link between type 1 diabetes and gluten
Type 1 diabetes is an autoimmune disease that develops when insulin-producing cells in the pancreas are destroyed . Interestingly, it is known that patients with type 1 diabetes often have celiac disease, a digestive disorder caused by an autoimmune response to gluten. The reasons for the co-occurrence of type 1 diabetes and celiac disease are not fully understood, but it is thought that a common autoimmune mechanism is involved in both diseases .
It has also been pointed out that gluten may increase the risk of developing type 1 diabetes. One study suggested a positive correlation between gluten intake during childhood and the onset of type 1 diabetes. This shows that there is a close relationship between type 1 diabetes and gluten . It is important to pay attention to the effects of gluten on type 1 diabetes patients.
Effect of gluten-free diet on type 2 diabetes patients
Type 2 diabetes develops primarily due to insulin resistance, which reduces the effectiveness of insulin. As mentioned above, gluten can increase insulin resistance, so a gluten-free diet is expected to be effective in managing type 2 diabetes . In fact, studies on type 2 diabetes patients have reported that a gluten-free diet improves blood sugar control.
One study found that following a gluten-free diet for 12 weeks resulted in a significant decrease in HbA1c levels . A gluten-free diet may also be effective for weight management. Because gluten-rich foods are often high in calories, avoiding them can reduce energy intake . Weight loss is known to lead to improved insulin resistance. Thus, a gluten-free diet appears to be a useful option for patients with type 2 diabetes. However, it cannot be recommended to all patients, and decisions must be made based on each individual's situation.
Gluten control as a preventative measure against diabetes
Both genetic and environmental factors are involved in the development of diabetes. Gluten intake, as one of the environmental factors , may also play an important role in diabetes prevention . As mentioned above, gluten can increase the risk of developing type 1 diabetes and worsen insulin resistance in type 2 diabetes. Therefore, properly controlling gluten intake may lead to primary prevention of diabetes .
It is especially recommended that high-risk groups, such as those with a family history of diabetes or those prone to obesity, pay careful attention to their gluten intake. However, restricting gluten too much can actually disrupt nutritional balance. The important thing is to moderately control gluten intake and practice an overall healthy diet . It is essential to find a way to deal with gluten that suits you while monitoring your blood sugar regularly.
How to go gluten-free
In order to practice a gluten-free diet, it is essential to choose your daily meals well and be creative when eating out. Here we will explain in detail the key points to living a gluten-free diet . Please use this as a reference when preparing your daily meals and eating out.
How to Choose Gluten-Free Foods
To create a gluten-free diet, you first need to be able to distinguish between foods that contain gluten and those that do not . Below is a checklist of foods that are high in gluten and gluten-free alternatives.
Gluten-rich foods checklist
Some of the most common foods that are high in gluten are:
- Flour (bread, pasta, pizza, cakes, cookies, etc.)
- Barley (beer, barley tea, barley shochu, etc.)
- Rye (rye bread, rye whiskey, etc.)
- Buckwheat (only those made with buckwheat flour)
- Some processed foods (sauces, dressings, soup bases, etc.)
When purchasing processed foods, it is important to carefully check the ingredient label . If the label contains words such as "wheat," "barley," or "rye," it is likely that the food contains gluten, so be careful.
Use of gluten-free alternatives
To avoid gluten, it is effective to use gluten-free alternatives . The following foods can help you create a gluten-free diet:
- Rice flour, multigrain flour (substitute for bread and pasta)
- Almond flour, coconut flour (substitute for wheat flour)
- Quinoa, amaranth (grain substitutes)
- Cornstarch, potato starch (alternative thickener)
Using these foods, you can make bread and sweets without using wheat flour, and thicken dishes . Recently, there are many gluten-free foods on the market, so we recommend making use of them.
Tips for eating out
If you're on a gluten-free diet, you may have some trouble when eating out. However, with some advance preparation and ingenuity, you can still enjoy eating out even if you're gluten-free . Here are two points to keep in mind when eating out.
Check the gluten-free menu
When eating out, it's a good idea to check the restaurant's menu in advance. Recently, an increasing number of restaurants have started offering gluten-free menus . Check the restaurant's website or gourmet site to see if they offer gluten-free options. You can also get more detailed information by calling the restaurant. Doing your research beforehand is essential to enjoying gluten-free meals safely and smoothly .
Ask the staff to remove gluten
Even if there are no gluten-free options on the menu, there's no need to give up. You can ask the staff to remove gluten and they may be able to accommodate . For example, you can make the following request:
- "I'm allergic to gluten, so could you please make it without wheat flour?"
- "Can I have the sauce served separately?"
- "Do you have gluten-free menu items?"
Some restaurant staff may not be familiar with the details of gluten-free options. In such cases, it is effective to specifically state that you would like no wheat, barley, or rye . By taking these measures, you should be able to enjoy a fulfilling dining experience even if you are gluten-free. However, since it is difficult to guarantee 100% safety, caution is essential for those with severe allergies.
