Skin rashes from eating certain foods are worrisome.  The itchy, red, bumpy rash appears on your face, neck, or around your mouth soon after you eat. A skin rash can pop up on your hands or arms when you touch certain foods. You may wonder if you should eliminate certain foods from your diet. So, what foods make skin rashes worse? What foods will help calm this type of breakout?

Your diet might be the cause of your skin rash!

There’s a growing awareness that the food you eat affects every part of your health. If you have a food allergy, you may be prone to skin rashes. Research studies found that your diet can set off eczema. Eczema is a word used to describe a group of skin conditions that cause inflammation, itchiness, red, dry, or bumpiness of your skin.

Most of the time, eczema refers to a condition called atopic dermatitis. If you eat food you’re allergic to your body goes into overdrive. Your immune system’s overreaction releases mast cell chemicals that cause a hypersensitive reaction like histamines.

A reaction can happen minutes or hours after eating the food. Some delayed reactions occur as long as a couple of days later.

Gut and skin connection

A recent study found that scratching your itchy skin irritated by eating foods triggers your immune cells in your small intestine. The scratching sets off a gut reaction. This situation is why there may be varied reactions in people with food allergies. Your food allergy can set off atopic dermatitis or stomach problems or both. You may get a skin rash from foods without a stomach reaction, but some researchers suggest that if you have one result, you are prone to the other response. So, what are common food allergy symptoms? Here is a list you may encounter if you’re allergic to certain foods:

  • Hives
  • Itchiness or eczema (atopic dermatitis)
  • Tingling around or inside your mouth
  • Red skin
  • Swelling of your face, lips, tongue or throat-see your doctor right away
  • Wheezing, trouble breathing-see your doctor right away
  • Dizziness, lightheadedness
  • Vomiting
  • Diarrhea
  • Watery eyes
  • Abdominal cramping

Ten foods that worsen your skin rash

There’s an increasing number of food allergies, especially in developed countries.  If you think you have a food allergy, contact your doctor or allergist. They will ask for your medical information, a  blood test, and a skin prick. It takes all of this information to figure out if you’re allergic to food. Blood tests alone aren’t as practical. Certain foods are the most common ones to cause allergies. Here are the top ten foods that can give you a skin rash due to an allergic reaction.

1. Peanuts

Peanut allergies are widespread. Sometimes peanut allergies are life-threatening, causing anaphylaxis or trouble breathing. Even a small bite can cause an allergic reaction for some people.



A peanut allergy is your immune system mistaking the peanut proteins as dangerous. Your immune system releases mast cell chemicals such as histamines into your bloodstream, giving you an allergic reaction. An allergic reaction may occur minutes after you’re exposed to peanuts. Skin rash symptoms to peanuts include stuffy nose, skin reactions like hives, swelling, or redness over a large area.

2. Tree nuts

Tree nut allergies are increasing, and the reactions can be acute. Part of the reason for the growing number of tree nut allergies is that they’re being used more and more in baked goods and processed foods. Studies found that nine tree nuts cause the most allergic reactions. These include:

Tree nut reactions can be life-threatening. The same study reported that 70% to 90% of all food-related anaphylactic deaths are from tree nuts. They can also cause severe atopic dermatitis.



3. Cow’s milk

Cow’s milk is another common allergy that causes skin rashes. If you’re allergic to cow’s milk, your immune system will overreact to the protein in milk from the cow. Further, if both parents have atopic dermatitis from a milk allergy, the chances of a child having this allergy increase 40% to 60%.

4. Eggs

Egg allergies are more common in kids than adults. But there are cases of adult-outbreak egg allergies. A reaction may happen within minutes of eating an egg. Symptoms include skin rashes, hives, congestion, or digestive problems. These can range from mild to more severe reactions such as hives-red welts on your body.
