You may be thoughtfully caring for your skin each day but inadvertently overlooking one food proven to increase your risk of acne, dermatitis, canker sores, and several other skin conditions. Eliminate this protein, and you may experience healthier skin.
Story at a Glance
- While you may take great care with the outside of your skin each day, the foods you’re eating may be doing greater damage.
- Close to 6 percent of people in the United States are gluten-sensitive, which affects blood glucose and insulin resistance and triggers skin damage.
- Some grain products can act like wheat, increasing gut permeability and overall inflammation in your body.
Your skin is the largest organ in your body, responsible for temperature control, protection, and excreting toxins, to name just a few. Far from just being an inactive covering for your internal organs, your skin is an intricate system of nerves, glands, and cell layers that plays a fundamental role in your overall health and wellness.
If you want to protect your skin, age gracefully, and reduce problem breakouts, it is time to care for your skin in the same way you care for your heart, control your weight, and lift your mood. In other words, pay attention to the foods you eat every day.
Number of People With Gluten Sensitivity Rising
The extreme form of gluten sensitivity, celiac disease, affects people differently. Over 200 symptoms have been attributed to the condition. Approximately one in 133 people in the United States suffer from celiac disease,1 and close to 6 percent suffer from gluten sensitivity.2 Dr. Alessio Fasano is the director of celiac research and the chief of pediatric gastroenterology and nutrition at Massachusetts General Hospital. In a Celiac Disease Foundation blog, Dr. Fasano said:3“We also know that prevalence is rising and we’re in the midst of an epidemic. Based on our study it seems that prevalence has doubled every 15 years in North America.
“Why? I think it goes back to the microbiome. There are antibiotics, our diet has changed, we travel more. There have been so many changes in the past 50 years … We don’t digest gluten completely, which is unlike any other protein. The immune system seems to see the gluten as a component of bacteria and deploys weapons to attack it, and creates some collateral damage we call inflammation.”
5 Skin Conditions Triggered by Grains
There are several different skin conditions associated with the changes that happen in your body when you eat wheat and other gluten-containing foods. Whether you have celiac disease or a gluten sensitivity, you are at higher risk for suffering these skin conditions when you eat gluten:- Acne: This skin condition affects nearly 80 percent of all people between ages 11 and 30 in Western cultures.5 In contrast, the condition is virtually nonexistent in primitive societies. Hunter-gatherer communities in Paraguay were observed for three years, during which no acne on individuals was found.6 The type of symptoms from gluten sensitivity are different from celiac disease, but both include an increase in adult-onset acne.7
- Atopic dermatitis: Researchers have found that atopic dermatitis is three times more likely in people with celiac disease and two times more likely in families who have members with celiac disease.9
- Psoriasis and eczema: Psoriasis is uncomfortable and sometimes disfiguring, while eczema is a term applied to a wide range of different rashes that are itchy, red, and dry. One-third of the U.S. population will experience eczema at some point in their lives. Prevalence at least doubled between 1995 and 2008. Eczema is driven in part by an allergic response and often linked to other allergic reactions, such as asthma, allergic rhinitis, and acid reflux.10 Psoriasis often affects large areas of skin and is an immune reaction linked to grain proteins, namely gliadin. In one study, participants who tested positive for antibodies to gliadin improved when they were placed on a gluten-free diet.11 The National Psoriasis Foundation also recommends those with celiac disease or gluten sensitivity adhere to a gluten-free diet to reduce or eliminate their symptoms.12
- Recurrent aphthous stomatitis (RAS): Although they appear similar on the surface, these mouth ulcers or canker sores are not related to cold sores caused by the herpes virus. They can be a minor annoyance or become so painful they inhibit eating and speaking. In a paper published in BMC Gastroenterology,13 the authors propose that RAS may be the only visual symptom of gluten sensitivity and recommend patients presenting with RAS be evaluated also for celiac disease.
- Vitiligo: In this skin condition, the pigment is lost, causing white patches to appear. Although not dangerous, it can have a profound effect on an individual’s life. A case report of a 22-year-old young woman with vitiligo was published in Case Reports in Dermatology.14 After previously undergoing medical therapy without success, she was placed on a gluten-free diet. Partial but rapid repigmentation occurred in the first month and stabilized after four months of remaining gluten-free. The authors suggest that diet modifications, including a gluten-free diet, should be considered for the treatment of vitiligo.
Wheat Proteins Cause Problems
“There’s no human requirement for grains. That’s the problem with the USDA recommendations. They think we’re hardwired as a species to eat grains. You can get by just fine and meet every single nutrient requirement that humans have without eating grains. And grains are absolutely poor sources of vitamins and minerals compared to fruits and vegetables and meat and fish.”
- Gliadin: Gliadin is the primary immunotoxic protein found in wheat gluten and is among the most damaging to your health. Gliadin gives wheat bread its doughy texture and is capable of increasing the production of the intestinal protein zonulin, which in turn opens up gaps in the normally tight junctures between intestinal cells (enterocytes).
- If you suffer from celiac disease, your body will make antibodies to gliadin, resulting in damage to the delicate, absorptive surfaces of your intestines. Many people who have gluten sensitivities also experience adverse effects of the gliadin protein. This may explain why research is clearly demonstrating an increase in intestinal permeability after exposure to gliadin in those with and without celiac disease.
- Lectins: Lectins are a key mechanism plants use to protect themselves and perpetuate the plant species. They are found in highest concentration in their seed form. When animals eat foods with lectin, they may experience digestive irritation, the degree of which depends upon how many generations the animal has been eating the particular plant food.
Other Grains Act Like Wheat
If you suffer from celiac disease or have a gluten sensitivity you may want to avoid all types of gluten to reduce your potential for skin problems. There are other non-wheat grains, and even some vegetables, that have similar properties to wheat. The following foods contain chitin-binding lectins similar in nature to wheat lectin (WGA) described above. Chitin-binding lectins and wheat lectins are functionally identical and may cause similar responses in your body. These foods are:- Barley.
- Potato.
- Rice.
- Rye.
- Tomato.
Gut Permeability Releases Toxins
Gluten increases the permeability of your intestinal tract, also called leaky gut. Gaps develop between the cells that make up the lining of your intestines, allowing undigested food, bacteria, and metabolic waste products to leak into your bloodstream. Hence, the name leaky gut syndrome. These foreign substances challenge your immune system and increase inflammation in your body.16Blood Sugar and Insulin Spikes Affect Your Skin
Wheat affects both your blood sugar levels and your release of insulin. Wheat is a carbohydrate and, once metabolized, increases your blood glucose levels and triggers the release of insulin and an insulin-like growth factor called IGF-1. This growth factor may increase the secretion of male hormones, such as testosterone.The release of male hormones is not enough to trigger the growth of secondary sex characteristics, such as hair or muscle growth, but may be enough to increase the secretion of sebum. This is a greasy substance on your skin that traps acne-promoting bacteria. IGF-1 may also cause skin cells known as keratinocytes to multiply, a process associated with acne.
However, it isn’t only wheat that spikes your blood sugar and insulin release. I strongly recommend you consider focusing on eating a diet high in whole foods, with little to no processed foods.
The Paleolithic Option
Controlling acne requires a whole-body approach. Removing wheat and gluten from your diet is highly recommended to reduce inflammation and your potential for further skin damage.Thousands of years ago, during the Paleolithic period, people were hunter-gatherers and ate primarily the meat they could hunt and plants from their environment. Missing from this ancestral diet were refined sugars, high-fructose corn syrup, and refined wheat products—ingredients we now know are strongly associated with insulin resistance and poor health.
“Normalizing your system is the true strength of the so-called caveman diet. By eating foods that are concordant with your genetic ancestry, you can avoid many of the diseases associated with our modern diet. ...
“This genetic discordance ultimately manifests itself as various chronic illnesses, which have been dubbed ‘diseases of civilization.’ By severely reducing or eliminating these foods and replacing them with a more healthful cuisine, possessing nutrient qualities more in line with the foods our ancestors consumed, it is possible to improve health and reduce the risk of chronic disease.”Originally published Feb. 6, 2024, on Mercola.com
