So you’re a foodie and the words elimination diet bring fear into your heart. Believe me, I felt the same way and never thought I would take the route of drastically changing my diet. But there was a straw that finally broke the camel’s back for me, and it was the side effects from long-term use of a prescription topical medication. It’s the day I found out that the azelaic acid cream called Finecea had depigmented my skin.
This information isn’t easy to find and nobody told me until I refilled the prescription for Fineaca around the fourth time. I decided at that point that I would just wean myself off and use it once a day instead of twice a day. I kept using Finecea because I believed it was keeping the rosacea from completely flaring so I accepted that smaller red patches. But I should have discontinued immediately because the fact that the red patches still existed meant that it was no longer effective. Maybe using it became an addiction and maybe it was just desperation.
In any case, the fact that my skin became worse made me give up hope in all medications and focus on food as healing instead.
What is an Elimination Diet?
An elimination diet is a short-term eating plan that involves removing specific foods that are known to cause inflammation, digestive distress, or immune responses in some people. The goal is to remove one or more food items from your diet for several weeks and see if you experience any improvement. Then slowly reintroduce each food group one at a time to see if any symptoms return.
When done properly, an elimination diet can help you:
-
Pinpoint which foods are triggering your rosacea
-
Reduce chronic inflammation
-
Support gut health and digestion
-
Improve overall health
An elimination diet isn’t necessarily about never eating your favorite foods again. It’s more about taking a break from possible irritants to see how your body responds when they’re out of the picture. Below is a picture of me when I first started the gluten-free, dairy-free diet.
How Long Do You Have to Remove Items For?
The timeline for removing food items from your system through an elimination diet can vary, but here’s a general breakdown:
Physical clearance from digestive system:
- Most food physically passes through your digestive tract within 24-72 hours
- However, food particles and their metabolites can linger longer in some people, especially with slower digestion
Reduction of inflammatory responses:
- Initial improvement in acute symptoms (like bloating or digestive discomfort) can occur within 3-7 days of removing trigger foods
- More significant reduction in inflammation markers typically takes 2-4 weeks
- For conditions like rosacea or eczema, you might start seeing skin improvements after 6 weeks or more
Standard elimination diet protocol:
- Most practitioners recommend eliminating suspected foods for 4-6 weeks minimum
- This allows enough time for inflammatory responses to calm down and for your gut lining to begin healing
- Some protocols extend to 8-12 weeks for more complex cases or severe symptoms
Factors that affect timing:
- Your individual metabolism and digestive health
- How damaged your gut lining is (leaky gut can slow the process)
- Which foods you’re eliminating (some are more inflammatory than others like dairy and gluten)
- Your overall health status and stress levels
- Whether you’re taking supportive supplements or following other healing protocols
Keep in mind that if you have significant gut damage or autoimmune conditions, it may take several months of consistent dietary changes to see substantial improvements.
Why Remove Gluten and Dairy First?
Removal of gluten and dairy was phase one of my elimination diet. While there are many potential food triggers, gluten and dairy are two of the most common offenders, especially for people with rosacea, leaky gut, or inflammatory skin conditions.
Here’s why they’re often the first to go:
1. Gluten and Gut Permeability (aka “Leaky Gut”)
Gluten is a protein found in wheat, barley, and rye. In people with celiac disease, gluten causes a full-blown immune reaction. But even in those without celiac, gluten may still increase intestinal permeability, a condition known as leaky gut.
Leaky gut occurs when the lining of the small intestine becomes damaged, allowing undigested food particles, bacteria, and toxins to leak into the bloodstream. This can trigger an immune response, leading to chronic inflammation throughout the body, including the skin.
Since rosacea is an inflammatory skin condition, cutting gluten is often a logical first step to reduce systemic inflammation and give your gut lining a chance to heal.
2. Is Dairy Bad For Rosacea?
Dairy, especially cow’s milk products, can also contribute to rosacea flare-ups for some people. It contains:
-
Casein and whey, which some immune systems flag as foreign
-
Hormones that may aggravate skin
-
Natural sugars (lactose) that can cause bloating or digestive stress
Some people with rosacea have reported clearer skin, fewer bumps, and less flushing after removing dairy for a few weeks.
I recommend removing gluten and dairy from your diet for a couple of months at least. From personal experience, I think it takes even longer to see results because serious inflammation needs much more time to heal.
Read Labels Closely
Gluten and dairy can sneak into a lot of unexpected places, including:
-
Salad dressings
-
Protein bars
-
Soups and broths
-
Coffee creamers
-
Processed snacks
-
Seasonings and spice mixes
Make it a habit to read ingredient labels carefully and avoid anything that lists wheat, milk, cheese, casein, whey, or malt.
Tips to Make the Elimination Diet Easier
Here are a few ways to make some of your food reductions easier for you:
1. Meal Prep
You may feel hungrier initially. Make soups, stews, or roasted veggies so you always have something on hand. Have cut up fruits and veggies in the fridge, but don’t overdo the vegetables too much at first. Take your time to up your fiber or your stomach will feel very bloated.
2. Find Swaps
Try swapping dairy milk for almond milk and bread for quinoa (soak it first) and rice. Gluten-free breads contain starches which are just turn into sugar. I also don’t find them to be particularly tasty. Yes, its a major adjustment and some of the enjoyment you get from eating food will decline. It will take time to figure out which substitutes can satisfy the cravings.
3. Track Symptoms
Use a simple journal or notes app to track what you eat, how your skin looks, and how you feel. Hopefully in a month or two you will see your inflammation reduce.
4. Be Patient
Skin often takes a few weeks to catch up with what’s happening internally. Don’t get discouraged if changes aren’t immediate.
5. Work With a Nutritionist or Naturopath
If you’re unsure what to eat and really struggling, a practitioner can provide personalized support. Of course AI can help make you a full meal plan based on what you like as well.
My Dairy-Free Gluten-Free Experience
I stopped eating dairy and completely cut out gluten. When I first started the diet, I felt extremely tired. I was surprised to feel this way when I didn’t eat a lot of either food group regularly. I had a splash of milk in my coffee once a day and sometimes a spoon of plain yogurt. I mostly ate one slice of bread on the weekends or had pancakes which contained some wheat. The desserts I ate would be gluten or dairy, but I didn’t eat them every day. Even removing that much made a big difference on my body. I didn’t feel better until at least a month later.
Elimination Diet Mistakes I Made
The one mistake I made was ramping up the vegetables intake too quickly. I was constantly bloated and even thought I had a UTI from the way I was feeling. I realized later that I increased my fiber consumption took quickly.
So did I notice any difference in my rosacea? No, I didn’t. But here’s how I screwed up. Three months later I dropped the diet while on vacation and started eating dairy and gluten again without a slow reintroduction. This resulted in huge consequences for me and my inflammation went out of control.
A few weeks after this I returned to the dairy-free and gluten-free diet, but made some additional changes. My rosacea had gotten so bad that I knew I had to ramp things up. This time I removed sugar as well. The real torture began!
