Eczema, also known as atopic dermatitis, is a chronic skin condition that affects millions of individuals worldwide. Characterised by itchy, inflamed, and irritated skin, eczema can significantly impact one’s quality of life. While environmental factors and genetics play crucial roles in its development, diet is another element that may influence flare-ups. Many dermatologists in Singapore emphasise that understanding potential dietary triggers is key to managing eczema effectively. If you’re consulting a skin clinic in Singapore, these insights may come in handy for developing a tailored approach to your skin health.
Though eczema is primarily driven by a combination of genetic, environmental, and immune system factors, diet may act as a trigger for some individuals. Certain foods can provoke immune responses, leading to inflammation that manifests as eczema symptoms1. In fact, food allergies are recognised as a comorbidity of atopic dermatitis (AD), alongside asthma and hay fever. Research indicates that up to 60% of children with severe AD also experience food allergies2. Common food allergens in patients with severe atopic dermatitis include milk, egg, soy, wheat, peanut, tree nuts, fish and shellfish.
Still, the relationship between eczema and food allergies remains complex. A Danish population study has established that most children experience eczema prior to developing food allergies, indicating that food allergies are not the primary cause of eczema3. The research suggests that eczema may lead to skin inflammation and compromise the skin’s barrier function. When inflamed skin comes into contact with certain foods, it triggers an abnormal immune response, which can result in the development of food allergies.
1. Dairy products
For some people, milk, cheese, yogurt, and other dairy products can act as eczema triggers. This is particularly true in individuals with milk allergy. Dairy is a common allergen that can lead to skin inflammation in sensitive individuals.
Dermatologists at leading Singapore dermatologist clinics often recommend alternatives such as almond milk, soy milk, or oat milk for those with dairy sensitivities.
2. Eggs
Eggs are another potential culprit, especially in young children. Proteins in eggs can trigger an allergic reaction that leads to eczema flares in susceptible individuals. If you suspect eggs are a problem, it’s important to discuss this with your dermatologist or an allergist.
3. Seafood and shellfish
Seafood is a staple in Singaporean cuisine, but it can be a double-edged sword for eczema sufferers. Shellfish such as prawns, crabs, and lobsters are known allergens that might exacerbate eczema symptoms. Some dermatologists in Singapore advise patients to monitor their skin’s reaction after consuming seafood and to opt for alternative protein sources if necessary.
4. Nuts
Tree nuts, including almonds, cashews, and walnuts, are common allergens that may trigger eczema in sensitive individuals. If nuts are a staple in your diet, consider alternatives like seeds (e.g., sunflower seeds or chia seeds) that are less likely to cause issues.
5. Processed foods
Consumption of ultra-processed foods (UPFs), sugar-sweetened beverages, high carbohydrate UPFs and monosodium glutamate in childhood has been associated with development of allergic disorders including atopic dermatitis, food allergies, asthma and allergic rhinitis. This is based on a very recent study by the European Academy of Allergy and Clinical Immunology (EAACI).4 It is possible that these ingredients contribute to inflammation and exacerbate eczema symptoms.5
6. Spicy foods
Singaporean dishes are known for their bold flavors, but spicy foods can sometimes lead to skin irritation or flushing, which might aggravate eczema symptoms. Reducing the level of spice in your meals could help manage your symptoms.
7. Soy products
Soy is a common ingredient in Asian cuisine, from tofu to soy sauce. While soy allergies are less common than other food allergies, they can still be a trigger for some individuals with eczema. Observing your skin’s response to soy-based foods can help identify whether it’s an issue for you.
Managing eczema involves more than just identifying potential dietary triggers. Here are some expert-recommended strategies to help you stay on top of your eczema while enjoying a balanced diet:
1. Keep a food diary
Tracking what you eat and correlating it with flare-ups can be incredibly insightful. Dermatologists in Singapore often recommend keeping a detailed food journal to pinpoint potential triggers.
2. Consult a specialist
Whether you’re visiting a skin clinic in Singapore or working with an allergist, professional guidance is invaluable. A dermatologist can perform allergy testing to identify specific food sensitivities that may be contributing to your eczema, as well as provide tips on good skin care.
3. Follow an elimination diet
Under the supervision of a healthcare professional, an elimination diet can help identify problematic foods. This involves removing potential triggers from your diet and gradually reintroducing them to observe your skin’s reaction.
4. Focus on anti-inflammatory foods
Incorporating anti-inflammatory foods into your diet can help manage eczema symptoms. These include:
5. Stay hydrated
Dehydrated skin is more prone to irritation. Drinking plenty of water and consuming water-rich foods like cucumber and watermelon can support skin health.
If you’re struggling to manage eczema symptoms despite dietary adjustments, it’s time to seek professional help. Many skin clinics in Singapore offer comprehensive eczema management plans that include dietary counseling, prescription treatments, and advanced therapies. Dermatologists in Singapore are well-versed in the latest research and treatment options for eczema, ensuring you receive personalised care.
While food is just one piece of the eczema puzzle, understanding and managing potential dietary triggers can make a significant difference. With the guidance of a trusted dermatologist in Singapore and a proactive approach to your diet, you can take meaningful steps toward clearer, healthier skin. Remember, eczema management is a journey, and every small adjustment brings you closer to better skin health.
