Rash from Food Allergy

Food allergies are common among many people, and even infants and children. A food allergy mainly implies a negative bodily reaction upon the consumption of a particular food. Among the various symptoms of food allergies, a food allergy skin rash is the most common. Though the sensitivity of each individual (depending on age and general bodily reactions) to different foods varies, there are some common allergens that trigger a rash from food allergy. Here we try to understand the types of foods that can cause an allergic reaction in the form of a rash, certain symptoms that may help you identify the allergen, and the treatment procedure for the same.

Symptoms

Now a skin rash can occur for a variety of reasons. You will have to keep a check on the time the skin rash appears. Is it after eating any kind of food? It may then be classified as a rash from a food allergy. Such a rash may lead to the symptoms of eczema or dermatitis. Some signs of such a rash are:

• Inflamed skin
• Skin Redness
• Itchiness, that causes the skin to thicken after scratching
• Red Bumps on different parts of the body
• Dry skin patches
• Swollen hands and feet
• Puffed up eyelids, and swelling under eyes too
• Swollen Tongue
• Hives

Many people experience such symptoms around the mouth, namely, dry and itchy skin. This may be because, sometimes, when you are eating a particular food, its contact with your mouth can cause an immediate reaction and lead to such symptoms such as flaking skin and dry patches around the mouth.

Possible Foods Causing the Rash

You may find it difficult to pinpoint the food that causes the rash, because the most common allergens are foods that youmay be consuming on a daily basis.

• Peanut Butter
• Nuts
• Wheat (Allergy from Gluten)
• Milk
• Other Dairy Products
• Soy
• Shellfish
• Pork
• Yeast (in bread and other baked goods)
• Coconut
• Chocolate
• Mustard
• Sugar
• Tomatoes
• Berries
• Citrus Fruits
• Peas
• Cinnamon and other spices

Sometimes exotic fruits such as kiwi, and gourmet food such as caviar may also cause a rash due to an allergy.

Rashes in Children and Babies

The most common food allergens may cause rashes in babies too. However, seven particular foods have been identified as the most common culprits for this problem in them.

• Dairy Products
• Soy
• Shellfish
• Wheat
• Tree Nuts
• Peanuts
• Egg Whites

Another interesting finding is that, sometimes the allergens may pass on to babies through breastfeeding. In such a case, the mother should start avoiding certain foods, to be able to zero in on the food causing the allergic reaction in babies. In some cases, the introduction of solid foods may result in the outbreak of skin rashes. Therefore, it is essential that you wait for up to 6 months before introducing solid foods to them. Also, introduce these foods to them one by one, so you can identify the cause of the allergy. Doing so at the right age may actually help you prevent these allergies. Children may outgrow these allergies over time. However, if these occur in adults these allergies may be permanent unless identified and treated.

Facts about Rash From Food Allergy

There are certain facts that will help you in identifying food allergens and choose a suitable treatment for the same.

• A rash may not always show up immediately after consuming the allergen.It may take a day, or three to four days for a rash to manifest.
• If you are allergic to a particular food from a food group, chances are you are likely to develop a food allergy skin rash from eating other foods in the same food group. For instance, if you are allergic to milk, you are also likely to be allergic to cheese.
• As mentioned earlier, the sensitivity of each body to different foods varies. While in some cases the reaction may be a mild skin rash, in others it may be a more severe outbreak of red bumps and itchiness all over the body.
• Among children and babies, it is important to note that if a child is allergic to one particular food, the same nutrition should be provided by other different types of foods. The food allergens should not interfere with a child's nutritional requirements.
• Sometimes, the amount of the allergic food you consume may determine the severity of the reaction. A minimal amount of milk may cause a different reaction than a whole glass of milk.

Treatment

Because the food allergens are among food groups that we consume so often, it may be difficult to identify the culprit causing the allergy. However, there are still some ways of doing so, along with some tests to understand the cause of the rash.

• Maintain a food diary. If you notice that you are suffering from a rash more often than not, maintain the diary for a week, and the symptoms associated with the food you have consumed that day. This way you will be able to understand when the symptoms were mild and when they were at their peak, depending on the amount of food you have consumed.
• Eliminate one food from your diet at a time. For instance, don't eat bread for four days, and see if the symptoms reduce. Then avoid milk and see if the effect is the same. This way you will be able to zero in on the food allergen. Reintroduce the suspected foods after some time and see the effect it has on the body.
• Several skin and blood tests are conducted to pinpoint the source of the rash. However, these are rarely accurate. You should opt for these tests when the elimination procedure does not work for you.

In rare cases, a rash from a food allergy may be very severe. In such a case, consult your doctor immediately and do not waste time over the elimination of suspected foods or food diaries. Also, if a particular healthy food is keeping you away from your necessary nutritional requirement, ensure you find a similar healthy substitute, after consulting a nutritionist.
