Rosacea Triggers: The Diet Connection

what causes rosacea diet

Rosacea is a long-term inflammatory skin condition that causes a reddened or discoloured rash, typically on the cheeks or nose. While there is no cure for rosacea, certain foods may help reduce flare-ups, while others may trigger them. Some common trigger foods include spicy foods, hot drinks, dairy, cinnamon, and alcohol. On the other hand, foods rich in antioxidants and omega-3 fatty acids may help to reduce inflammation and improve rosacea symptoms. Additionally, dietary changes that support a healthy gut microbiome, such as increasing fibre intake and consuming prebiotics and probiotics, may also play a role in managing rosacea.

Dairy products

Additionally, hormones in milk may promote inflammation and acne, which could be a contributing factor to rosacea flares. Some individuals with rosacea experience outbreaks after consuming dairy, and it is recommended to limit or eliminate these products from the diet to determine if dairy is a trigger. This can be done by testing each dairy item individually and waiting to see if symptoms improve.

It is worth noting that not all foods have the same effect, and some people may be able to tolerate certain dairy products while others may not. Trial and error are often necessary to identify specific triggers. Additionally, keeping a food diary can help individuals with rosacea identify and avoid their triggers.

While dairy may be a trigger for some, a Chinese population study found no association between rosacea and the consumption of sweets, which may include dairy-based desserts. This highlights the need for further research to understand the complex relationship between diet and rosacea.

Spicy foods

Spicy ingredients that often lead to rosacea flare-ups include hot sauce, cayenne pepper, chilli powder, and red pepper. In a survey of more than 500 rosacea patients, 61% of those affected by spicy foods listed hot peppers as a trigger, followed by 52% for Mexican-style foods, 47% for chilli, and 46% for salsa. Other spicy foods that can trigger rosacea include hot peppers, horseradish, hot sausage, Cajun-style foods, and barbecue sauce.

While spicy foods can aggravate rosacea symptoms, they do not cause the condition itself. The underlying cause of rosacea is unknown, but current research suggests that genetic and environmental factors interact to trigger its onset.

If you have rosacea and want to continue eating spicy foods, you can try substituting certain spices with others that may not trigger flare-ups. For example, red pepper or chilli powder can be replaced with a mix of cumin and oregano. Traditional salsa can be substituted with a fruit-based version.

Alcohol

A survey by the National Rosacea Society found that certain alcoholic beverages could be affecting rosacea more than others. Of the respondents who were affected by alcohol, around two-thirds experienced a rosacea reaction after a single drink. Additionally, two-thirds of those affected by alcohol found that it only took one drink to cause a reaction.

The reason why alcohol may increase the risk of rosacea is not yet known. Alcohol consumption can cause flushing due to the release of histamine as a result of acetone and acetaldehyde metabolism.

It is important to note that not everyone experiences rosacea flare-ups due to alcohol consumption. In a survey of more than 700 rosacea patients, 10% rarely or never drank alcohol, and another 10% reported that consuming alcoholic beverages had no impact on their condition.

If you have rosacea, keeping a diary of your triggers can help you identify and avoid them in the future. This can include noting the type and amount of alcohol consumed, as well as the intensity of your rosacea symptoms. By understanding your triggers, you can make informed choices to manage your symptoms effectively.

Fatty foods

While the exact cause of rosacea is unknown, it is believed to be linked to ongoing inflammation in the body, which is caused by an abnormal immune response. This inflammation can also be caused by oxidative stress, which is a state where the body experiences high levels of oxidants, called free radicals, that can lead to cell damage.

Diet can have a significant impact on rosacea symptoms, and certain compounds in specific foods can either improve or worsen the condition. Fatty foods, in particular, have been associated with rosacea due to their role in chronic inflammation. A large study in China found that individuals with rosacea who frequently consumed fatty foods, such as fatty meat, fried foods, and lard, experienced worse symptoms. This may be due to an imbalance in the skin caused by a fatty diet, compromising the skin barrier and leading to symptoms like pain, burning, and stinging.

Additionally, fatty diets have been linked to a relative shortage of very-low-chain fatty acids in the skin, which can further contribute to skin issues. High-fat diets were significantly associated with specific subtypes of rosacea, including erythematotelangiectatic and phymatous rosacea. These subtypes are more susceptible to triggers and can result in symptoms such as facial flushing, redness, and skin discomfort.

It is important to note that triggers vary among individuals, and not all fatty foods will affect everyone with rosacea. However, due to the potential link between fatty foods and inflammation, it may be beneficial to limit or avoid these foods to manage rosacea symptoms.

If you suspect that fatty foods are triggering your rosacea, it is recommended to consult a doctor or dietitian to determine the best dietary approach for your specific needs. They can provide guidance on how to make gradual dietary changes and suggest alternative food options to ensure you maintain a balanced and nutritious diet.

Gut health

Rosacea is a chronic inflammatory skin condition characterised by recurrent episodes of erythema, telangiectasia, papules, and pustules, primarily affecting the central face and periocular regions. The cause of rosacea is unknown, but it is thought to be a response to ongoing inflammation in the body, which may involve gut microbiome imbalances.

Gut Microbiome

The gut microbiome refers to the collection of bacteria that live in your gut. There will be a combination of good and bad bacteria making up your microbiome. The ratio of good to bad, as well as the level of growth and activity of these bacteria, determines the "health" of your microbiome. People with rosacea are often found to have more bad bacteria and less good bacteria in their gut.

Prebiotics and Probiotics

Prebiotics are a type of dietary fibre that promotes the activity and regulates the growth of beneficial bacteria in the stomach. Prebiotics are considered food for the bacteria living in the gut. They help promote bacterial growth and activity, which contribute to a healthy gut microbiome. Fibre-rich foods are considered prebiotics, so consider increasing the uptake of barley, green peas, lentils, dried dates, pasta, pistachios, and others.

Probiotics are foods that contain live "good" bacteria, which can contribute to a healthy gut microbiome. Certain types of good bacteria found in a healthy gut microbiome have been found to reduce inflammation in the skin of patients with rosacea. Sources of probiotics include fermented foods and supplements.

Synbiotics

Synbiotics are a combination of prebiotics and probiotics, substances that support a healthy gut microbiome.

Antioxidants

Antioxidants work to balance out the oxidants—a cause of inflammation—in the body, reducing the negative effects of oxidative stress and potentially impacting the underlying mechanisms of rosacea.

Trigger Foods

It is important to identify and avoid trigger foods, which can vary from person to person. Common trigger foods include hot foods, alcohol, chocolate, and compounds in certain fruits, vegetables, spicy foods, and meats.
