Foods that trigger eczema
Managing eczema can be a challenging journey for many patients. The condition affects not only the skin but also the overall quality of life, leading to significant discomfort and distress. In this article, we will explore foods to avoid and offer insights for medicine to avoid when undergoing a TCM treatment for eczema.
Understanding Eczema and Its Triggers
Eczema is a chronic inflammatory skin condition characterized by symptoms such as redness, itching, and dryness. Flare-ups can be caused by various factors, including stress, environmental irritants, and dietary choices. Certain foods and substances may exacerbate eczema symptoms by increasing inflammation, internal heat, or dampness in the body. By identifying and avoiding these triggers, individuals can effectively manage their condition.
Foods and Substances to Avoid for Eczema
1. Immunosuppressive Medications and Therapies
Patients undergoing treatment for eczema should be cautious about certain immunosuppressive medications and therapies. While these may be prescribed for severe cases, they come with risks of side effects and long-term complications:
- 皮质类固醇（激素）Steroids
- 放射疗法（UVB, PUVA）Ultraviolet Radiation Therapy
- 氨甲蝶呤（MTX, Methotrexate）
- 硫唑嘌呤（Azathioprine）
- 霉酚酸酯（MMF, Mycophenolate Mofetil）
- 羟基脲（Hydroxyurea）
- 硫鸟嘌呤（Thioguanine）
- 环磷酰胺（Cyclophosphamide）
- 苯丁酸氮芥（Chlorambucil）
- 阿霉素（Doxorubicin）
- 蓓萨罗丁（Bexarotene）
- 环孢霉素（Cyclosporine）
- Tacrolimus （FK506）
- 吡美莫司（Pimecrolimus, ASM981）
- 西罗莫司（Sirolimus）
- 来氟米特 (Leflunomide)
Although these medicines may provide temporary relief from the discomfort of eczema, but they can suppress immune function, impairing the skin’s ability to heal and potentially causing adverse reactions. Patients looking for a more natural healing approach are encouraged to consult TCM practitioners for safer alternatives.
2. Herbs and Natural Substances
Some natural herbs and substances, while beneficial for general health, may trigger eczema flare-ups or interfere with healing in sensitive individuals. Examples include:
- 甘草 (Glycyrrhiza glabra, Licorice) and derivatives (Glycyrrhizic Acid, Glycyrrhetinic Acid, Licochalcone): Known for their anti-inflammatory properties but may increase cortisol levels and worsen eczema symptoms in some cases.
- 金银花 (Lonicera, Honeysuckle)
- 夏枯草 (Prunella vulgaris, Selfheal)
- 土茯苓 (Smilax glabra, Glabrous Greenbrier)
- 白鲜皮 (Dictamnus, Dittany Bark)
- 蝉蜕 (Cryptotympana pustulata, Cicada Slough)
- 大黄 (Rheum, Rhubarb)
- 雷公藤 (Triperygium wilfordii, Threewingnut)
- 苦参 (Sophora flavescens, Light Yellow Sophora Root)
- 柴胡 (Bupleurum, Thorowax)
- 虎杖 (Polygonum cuspidatum, Japanese Knotweed)
- 决明子 (Semen Cassiae, Cassia Seed)
- 豨莶草 (Herba Siegesbeckiae, Siegesbeckia Herb)
- Cortex Lycii Radices (Chinese Wolfberry Root Bark)
- Radix Gentianae Macrophyllae (Largeleaf Gentian)
- 冬虫夏草 (Cordyceps sinensis, Caterpillar Fungus)
Certain chinese medicine for eczema, such as turmeric, may be commonly recommended for their anti-inflammatory benefits due to curcumin. However, it can be an inflammatory food for individuals with eczema. Turmeric can provoke adverse reactions, leading to skin irritation, redness, and increased itching, all of which can exacerbate eczema symptoms.
While licorice is recognized for its soothing properties, it can also trigger eczema symptoms because of its glycyrrhizin content. Consuming licorice may increase cortisol levels, disrupting the body’s hormonal balance and worsening inflammatory conditions such as eczema.
A research paper on an immunosuppressant derived from Glycyrrhiza uralensis (Licorice, Gan Cao) revealed that glycyrol exhibits immunosuppressive activity, likely due to its inhibitory effect on calcineurin (CN) activity. This suppression reduces IL-2 production and regulates T lymphocytes. As a result, glycyrol shows potential as a promising candidate for the development of a new immunomodulatory drug.
3. Animal Proteins
Certain foods may trigger eczema flare-ups for some individuals. Among these, animal proteins can be particularly problematic. For instance, while chicken meat is a lean source of protein, it may provoke inflammatory responses in individuals sensitive to certain proteins or if the chicken is not organic or free-range.
Notably, a dramatic increase in broiler growth rates was recoded between 1957 and 2005, marking an increase of over 400% . Due to commercial genetic selection, this rapid growth, which achieved through intensive breeding practices, had led to significant changes in the chickens’ biology. These included alterations in muscle composition, fat distribution, and immune responses. These unintended consequences may affect the protein structure or overall quality of the meat, making it more likely to trigger inflammatory reactions in sensitive individuals.
Similarly, fish oil, although often praised for its omega-3 fatty acids, can cause inflammation in those with eczema. The effects may be worse if they have seafood allergies or if the oil is contaminated with toxins.
4. Sugary Foods
The effects of eczema can intensify with the consumption of high-sugar foods, such as sweets and desserts. Excessive sugar intake tends to disrupt the body’s natural balance and results in more severe skin reactions. To manage your symptoms effectively, it’s recommended to limit sugary snacks and choose whole fruits instead.
To investigate whether the sweetener sucralose affects the immune system, scientists conducted laboratory tests exposing immune T cells from mice and humans to the sweetener. The results, published in Nature on 15 March, revealed that sucralose impaired the T cells’ ability to replicate and specialise, thus suppressing immune responses. This finding is particularly relevant for individuals with eczema, as consuming sugary foods or artificial sweeteners may exacerbate symptoms. Impaired immune function can lead to increased inflammation, potentially triggering or worsening eczema flare-ups, highlighting the importance of avoiding sugary or sweetened foods to manage the condition.
5. Processed Foods
Packaged snacks and ready meals are another type of food to avoid for eczema. Artificial ingredients, preservatives, and chemical additives found in processed foods can throw off the body’s natural equilibrium and cause skin irritation. Furthermore, these often contain high levels of sugar and sodium, which can worsen skin conditions.
Research from the International Study of Asthma and Allergies in Childhood highlights the impact of diet on the development and persistence of Atopic Dermatitis (eczema). Adolescents who frequently consume fast food are at a 20% increased risk of developing AD, with the risk of severe AD jumping to 70%. While the specific dietary factors responsible were not conclusively identified, high sodium intake—a common feature of fast food—has been implicated. Therefore, focusing on whole, unprocessed foods to adopt a TCM eczema diet is vital for reducing triggers.
Embracing a TCM dietary choices
In Traditional Chinese Medicine (TCM), dietary choices are viewed as a key element to maintain balance within the body. Making dietary changes for eczema management by incorporating nutrient-rich, anti-inflammatory options helps to nurture your skin’s health. Foods such as leafy greens, whole grains, and lean proteins can provide the nutrients necessary for healing and overall well-being.
Taking control of your diet can contribute to significant improvements in your eczema symptoms. Remember, small changes like avoiding foods that trigger eczema can make a big difference on your path to healing.
