What is rosacea?
Rosacea, a skin condition that causes redness of the skin similar to blushing, is common in many adults. While there is no one specific rosacea diet, some food may help combat rosacea. Similarly, avoiding triggering foods can also help decrease inflammation associated with rosacea.
Ultimately, finding foods that are good for rosacea requires some trial and error. However, there are common inflammatory foods to avoid and anti-inflammatory foods to try.
Symptoms of rosacea
Rosacea is a common, chronic inflammatory skin disease that often occurs on the face. Symptoms of rosacea include:
- Flushing or the appearance of blushing
- Dilated blood vessels
- Swelling of the nose
Rosacea can affect anyone of any age, but it most commonly occurs in fair-skinned women who are middle-aged and have blonde hair and blue eyes. While it is less prevalent in men, the symptoms tend to be more severe for men who develop rosacea.
Causes of rosacea
Researchers have not yet pinpointed the cause of rosacea. However, some possible contributors include:
- Immune function
- Mites on the skin, like demodex
- Helicobacter pylori (H. pylori) bacteria
- Issues with cathelicidin, a protein on the skin
While the exact cause of rosacea remains unknown, it is known to be an inflammatory condition. Inflammation associated with rosacea can be triggered by many factors, including:
- Stress or anxiety
- Changes in the weather, such a strong wind or humidity
- Sun exposure and sun-damage
- Alcohol consumption
- Smoking cigarettes
Food is both a common trigger and remedy for rosacea. Understanding what triggers your rosacea is an important part of managing symptoms.
Foods that help rosacea
Research suggests that diet can have a significant impact on a variety of dermatological conditions, including rosacea.
Some foods high in healthy fats are:
- Fish high in omega-3, like salmon, herring, sardines, mackerel, and lake trout
- Certain nuts and seeds, including walnuts, hemp seeds, flaxseeds, and chia seeds
- Peanut butter
- Olive oil
Probiotic and prebiotic-rich foods
Studies show a link between inflammation and diseases of the gut and rosacea. Many people experience rosacea together with irritable bowel syndrome (IBS) and other gastrointestinal conditions. This connection suggests both a link between inflammation of the gut and the skin and that the digestive system may be an effective avenue for treatment of rosacea.
Research suggests that probiotics and prebiotics may be effective for managing rosacea, especially in chronic patients. Probiotics may help soothe inflammation and minimize rosacea symptoms and flare-ups. Probiotic foods to try include:
- Certain cheeses
Prebiotic foods include fibrous foods such as:
- Whole grains
- Onions and leeks
While these foods may help manage rosacea, there are a wide range of triggers for inflammation. Keep in mind that it is possible that foods that soothe your symptoms may trigger someone else’s and vice versa.
Foods that trigger rosacea
The impact of dietary habits on rosacea is well-documented. There are many foods that trigger inflammation related to rosacea. Some common triggers include:
- Sour cream
- Certain cheeses
- Chocolate and vanilla
- Soy sauce
- Yeast extract
- Lima beans
- Some citrus fruits
- Spicy foods
- Foods hot in temperature
- Foods high in histamine
Once you determine your triggers through daily food tracking, you should avoid triggers moving forward.
Risks and outlook for rosacea
Ultimately, there are many foods that fight inflammation, but triggers for rosacea vary widely from person to person. While there are common triggers and anti-inflammatory foods, the right diet for you may depend on the type of rosacea you are experiencing and other genetic factors.
As such, determining which diet is right for your rosacea may require trial and error. Always consult with your physician before changing your diet.
