Diet is a major part of dermatographia. What you eat can have an effect on how your body responds. Cutting out certain foods from my diet helped me eliminate symptoms. And I believe they can help others too.

Here is the bottom line. Consuming alcohol, sugars, grains, caffeine, and dairy can enhance or even cause inflammation. Focusing on eating fruits, vegetables, and fish make living with autoimmune conditions easier.

Noticeable changes show quickly when you shift your diet. Avoiding trigger foods and maintaining a well-balanced diet can stop symptoms within days. Eating right can also prevent redness, swelling, and welts to appear.

The first step to taking control of dermatographia is by taking control of your diet. Eating foods that cause a bad reaction means letting food control your body, not the other way around. Incorporate healthy, immune-boosting foods into your diet and take that control back.

Some foods make dermatographia worse. Here are a few that should be limited in your diet:


Grains are the seeds from the Poaceae family and commonly called cereal grains. This includes wheat, barley, rye, corn, millet, oats, rice, spelt, and others. Cereals, breads, oatmeals, and most processed foods have some type of grain in them. Many easy-to-make, grab-and-go snacks and foods contain these grains, too.

So if grains are in almost all foods, why are they not good? Like most food, people have different reactions to different foods. Some people can digest the grains and not show any reactions to them. But if you have an autoimmune problem, then grains are your enemy.

Grains have lectin, plant proteins that bind to carbohydrates and can cause inflammation in our bodies. Grains are not easily broken down which causes a strain in the digestive system. Undigested and partially digested food leads to bacterial overgrowth and can contribute to leaky gut.


The standard diet most Americans live by tend to be high in sugar. Those with autoimmune conditions, like dermatographia, are susceptible to the negative effects. According to The American Journal of Clinical Nutrition, sugars in all forms—glucose, fructose, and sucrose—can impair immune system function.

Sugar is not a friend to your gut. Blood sugar imbalances inflame the digestive system which in turn triggers a negative reaction for your autoimmune system. Sugar also causes inflammation and compromises the ability of your white blood cells to destroy toxins. This starts within 30 minutes of eating sugar and lasts up to 5 hours.

The best thing for your immune system and digestive system is to eliminate sugar from your diet. Sugar consumption should be at a minimal and kept at around 5% of your diet if you can’t cut it out completely. Eating a breakfast of high protein and healthy fats helps to kick sugar habits to the curb.


Many sources out there say that alcohol is terrible for you, while others say a glass of red wine a day is good for you. With all this conflicting noise out there, how do you know which is right for you? Looking closely at your own diet and history will help you know which side to lean toward.

Dermatographia is an autoimmune disorder that needs to be taken into account when researching about healthy foods to eat. Alcohol consumption amplifies the impact of negative stress on the body. This can reduce your immune system’s ability and your overall health. Alcohol suppresses inflammatory mediators that help fight infection. Too much alcohol can lead to altered immune function and chronic inflammation, both of which are signs of autoimmune disease.

But some sources out there say alcohol is good for some autoimmune diseases like Hashimoto’s. For me, limiting my alcohol consumption drastically lowered my dermatographia symptoms. If you are consuming alcohol, look at the labels. Finding alcohol with low sugar content is important as sugar is not good for your gut health.

Closely monitor your diet to see what affects you. Remember, this is a process and will take time and be patient with yourself. Some foods and drinks will cause more symptoms of dermatographia than others. The best course to take is trial and error.

I started by cutting out sugar, grains, caffeine, alcohol, dairy, and red meats from my diet. After detoxing for a week, I slowly added each item into my diet day by day. I immediately saw my dermatographia come back almost immediately after consuming sugars and grains, but not so much for red meats. Everyone will react differently, so see what foods affect you more than others.
