Why Is Gluten Bad For You? Analyzing The Harm Behind This Food

Gluten is one of the most controversial food contents. As a result, it has sparked numerous debates on whether it is good or bad for you. Depending on your argument, you stand on one side or the other. However, when it comes to science, only one side can win this debate. Most food experts classify gluten as bad for your health. But why is gluten bad for you? This is the main focus of this read.


What Is Gluten?

Before we detail why you need to stay away from gluten, let’s clarify what it is. Medical News Today defines gluten as a class of proteins found in spelt, rye, wheat, and barley (6).

It is prevalent in wheat. Gluten is made up of two proteins, namely gliadin and glutenin. The two bind to each other to form a network that supports dough. The network allows bread to become light and fluffy.

Although the two bind to each other, gliadin happens to be the primary culprit of the most adverse health effects associated with gluten (6).

Foods That Have Gluten

Gluten is found in foods and drinks that have barley, wheat, rye, or triticale grains (7). We also include durum, Kamut, emmer, spelt, and einkorn when we talk of wheat. There are so many foods that are prepared with these grains. The gluten foods to avoid include (7):

  • Flour tortillas
  • Pizza
  • Noodles and pasta
  • Pastries and baked goods
  • Many desserts
  • Processed meats
  • Self-basting meat
  • Brown rice syrup
  • Some soy sauce types
  • Bread
  • Sauces and gravies
  • Beer
  • Malt derivatives like malt vinegar, malt-based beer, malt loaf, malted milk and milkshakes, and brewer’s yeast.
  • Breadcrumb and breading mixes

Some foods are said to be gluten-free, yet they are not. This is why you are advised to double-check the labels and nutrition facts. Some of the products you have to double-check include (7):

  • Tortilla chips
  • Potato chips
  • Candy
  • Some soups
  • Lunch meats
  • Some salad dressings, marinades, condiments, and sauces
  • Granola bars
  • Restaurant eggs because some use pancake batter to thicken, especially scrambled eggs.
  • Meat alternatives

  • Cosmetics like lip balm, lip gloss, and lipstick
  • Some vitamins and nutritional supplements
  • Toy dough
  • Dental products

Why Is Gluten Bad For You?

As seen above, gluten is found in some of the most common foods. These foods, for example, pizza and pasta, happen to be food favorites to some people. So, the thought of giving them up may not settle well among these people.

The only way such individuals can give up these foods is if there are solid reasons that gluten is bad for you. So here are some concrete reasons why gluten is bad for you:

  • It Triggers Celiac Disease

Celiac disease refers to an autoimmune condition that can damage your small intestine. It is sometimes known as celiac sprue or gluten-sensitive enteropathy (1). If you have celiac sprue, you are advised to avoid gluten foods.

These foods trigger an immune response in your small intestine. Down the line, the reaction damages the lining in your small intestine and hinders the absorption of some nutrients (1). We all know that a lack of nutrients may lead to nutritional deficiencies or malnutrition.

The intestinal damage causes several side effects, which also happens to be the signs of symptoms of celiac disease. These include diarrhea, nausea, abdominal pain, constipation, mouth ulcers, joint pain, bloating and gas, anemia, fatigue, and weight loss (1).

However, note that the signs and symptoms may differ in children and adults. Most children report more digestive problems than adults (7). Again, it is worth mentioning that celiac disease may lead to other severe complications if not managed. Some of these complications include:

  • Anemia
  • Nutritional deficiencies
  • Weight loss
  • Osteoporosis
  • Neurological conditions
  • Multiple sclerosis (MS)
  • Infertility

  • It Causes Gluten Sensitivity

Gluten sensitivity is also known as gluten intolerance. It occurs when some eat gluten foods. This condition highly resembles celiac disease, but without the small intestine damage (7). You can tell if you have gluten intolerance by looking out for various symptoms.

Note that these symptoms do not relate to the digestive system. They include limb numbness, joint pain, headaches, and having a cloudy mind (7). The best approach to know if you have this condition is visiting a health facility and being assessed.

  • It Causes Wheat Allergy

Eating food with gluten can also be harmful because it causes you to develop a wheat allergy. Note that wheat allergies are different from gluten intolerance and celiac disease. When you have a wheat allergy, you are allergic to all wheat proteins.

It so happens that most wheat proteins contain gluten. Most wheat allergy symptoms are digestive, but some are not. The most common symptoms include:

  • Itching, irritation, or swelling around your throat and mouth
  • Congestion
  • Difficulties breathing
  • Itching and swelling of your skin

Talk to your doctor if you report any of these symptoms. If you happen to have a wheat allergy, the chances are that you will be required to follow a wheat-free gluten-free diet.

  • It Causes Dermatitis Herpetiformis

The other reason why experts say gluten is bad for you is that it causes dermatitis herpetiformis. Dermatitis herpetiformis refers to an itchy, irritating, and blistering skin disease (1). You can get this if you have a wheat allergy or gluten sensitivity.

The irritation and blistering forms a rash on your knees, elbows, scalp, butt, and torso (1). Experts have linked this condition to the changes in the lining of your small intestine, similar to those caused by celiac disease (1).

However, the difference is that, unlike celiac disease, there are no digestive problems with dermatitis herpetiformis. Therefore, to control the rash, most doctors recommend a gluten-free diet or some medication.

  • It Provides No Essential Nutrients

Food experts have stated that gluten is bad for your health because they have not linked it to any nutritional benefit. According to Health Harvard, gluten has no nutritional benefits, meaning it denies you the health benefits associated with various nutrients (2).

These are some of the reasons why most people have chosen to embrace a gluten-free diet. However, before you buy into the gluten-free diet, you must know that this too has its pros and cons.

Yes, it saves you from celiac disease, dermatitis herpetiformis, gluten intolerance, and wheat allergies. However, it also has its fair share of downsides.

Is A Gluten-Free Diet The Solution?

You may think that this is the way forward. However, even if it is, experts ask you to be very conscious with a gluten-free diet. Although people argue that it is rich in nutrients, the opposite is true.

Health Harvard acknowledges that most gluten-free foods tend to lack essential nutrients. They are primarily foods less fortified with iron, folic acid, and other nutrients (7). Likewise, food experts have discovered that individuals who avoid gluten without gluten-related diseases like celiac disease have adverse effects (4). 

A gluten-free diet is more expensive to maintain than a gluten-containing diet. This may make it hard to follow for the long haul, affecting its sustainability (4). But, again, food experts also reveal that there are powerful pleasurable and communal aspects of food.

These aspects are deeply rooted in society, and the perceptions an individual has on food. Therefore, a gluten-free diet may require persistent dedication to the already restrictive diet and even require lifestyle changes.

Although it has good intentions, this may not sit well with most people. So, the diet may not be fully embraced and may lead to negative psychosocial impacts and maintenance difficulties (4). In addition, a gluten-free diet has also been found to lack fiber (5).

According to Medical News Today, most gluten-containing foods are high in fiber. So, when you cut them out, you limit your sources of fiber. It is for this reason that you are urged to take other foods rich in fiber.

These include foods like beans, nuts, seeds, lentils, and other gluten-free whole grains. If not, consuming a gluten-free low-fiber diet can increase your risk of heart disease (5).
