Quick Summary
• Most people do not need to remove gluten and dairy when trying to conceive unless they have a specific sensitivity or condition.
• Removing these foods without guidance can make diets more restrictive and lead to more processed food choices.
• A balanced, whole food fertility diet that supports hormones, blood sugar, and inflammation is usually far more beneficial.
Introduction
One of the most common questions I get from clients is: Should you cut gluten and dairy when trying to conceive?
Social media often suggests that removing these foods will improve fertility. Many women therefore cut them out straight away. However, the science is more nuanced. For some people it may help. For many others it is unnecessary and can make eating much harder. Understanding when gluten and dairy matter for fertility, and when they do not, is key.
Why Diet Matters When Trying to Conceive: Should you cut gluten and dairy when trying to conceive?
Nutrition plays an important role in reproductive health. The foods you eat influence hormone balance, egg quality, inflammation, and metabolic health. A nutrient rich fertility diet helps support ovulation and early pregnancy. For example, key nutrients such as folate, omega 3 fats, zinc, iodine, selenium, and vitamin D all play a role in reproductive health. Blood sugar balance is also important. Stable blood sugar levels support hormone regulation and ovulation. However, improving fertility through diet is usually about adding nourishing foods, rather than removing multiple food groups.
Should You Cut Gluten When Trying to Conceive?
For many people, gluten does not negatively affect fertility. Gluten is a protein found in wheat, barley, and rye. It is commonly present in foods such as bread, pasta, cereals, and baked goods.
In fact, whole grains can support fertility. They provide fibre, B vitamins, and important minerals. These nutrients help regulate blood sugar levels and support hormone balance. However, there are situations where reducing gluten may help.
When gluten may be worth reducing
Some women experience digestive symptoms or inflammation when eating gluten.
Reducing gluten may be helpful if you have:
• Coeliac disease
• Non coeliac gluten sensitivity
• Persistent digestive symptoms
• Autoimmune conditions
• Endometriosis / Adenomyosis
Some women with inflammatory conditions such as endometriosis may feel better with lower gluten intake.
That said, this is very individual. Gluten does not need to be removed automatically.
What About Dairy and Fertility?
Dairy is another food group often blamed for fertility issues. Yet research does not show that dairy universally harms fertility. Dairy foods provide valuable nutrients for reproductive health. These include calcium, iodine, protein, vitamin B12, and vitamin D. Some studies even suggest that full fat dairy may support ovulation in certain women. Fermented dairy foods such as yoghurt and kefir can also support gut health. A healthy gut plays an important role in immune balance and inflammation.
However, dairy is not suitable for everyone.
When dairy may not suit you
Some women notice symptoms after consuming dairy.
This may happen with:
• Lactose intolerance
• Certain inflammatory conditions
• Positive thyroid antibodies
• Some autoimmune conditions
In these situations, reducing dairy temporarily may be helpful. However, it is important to ensure those nutrients are replaced elsewhere in the diet.
What I Often See In Clinic
This week alone I have seen several clients who had removed both gluten and dairy while trying to conceive. They told me they found the diet really challenging. Many were unsure what to eat and felt quite restricted. As a result, they ended up relying heavily on gluten free breads, crackers, and snack foods.
The issue is that many gluten free alternatives are highly processed. They are often made with refined starches and additives and contain very little nutritional value. When these foods become the main replacement, the overall diet quality can actually decline.
Eating a lot of processed foods can contribute to inflammation, blood sugar imbalance, and nutrient deficiencies. These are the opposite of what we want from a fertility diet. A study has just been published this week looking at the impact of UPFs consumption in both men and women and the impact on fertility outcomes (https://pubmed.ncbi.nlm.nih.gov/41871947/). Consumption of UPFs in men increased the time taken to fall pregnant, and in women was associated with poor implantation and embryo development.
If you are going to remove food groups, it is important to understand why it matters for you specifically.
It is also essential to replace those foods with whole food alternatives that still meet your nutritional needs. For example, meals can include foods such as quinoa, lentils, buckwheat, vegetables, fish, eggs, nuts, and seeds instead of relying on processed substitutes. The goal is always to create a nourishing fertility diet, not simply swap foods for processed alternatives.
The Problem With Cutting Too Many Foods
When women remove gluten, dairy, sugar, soy, and other foods all at once, their diet can become very restrictive.
This can reduce intake of important nutrients needed for fertility and also lead to a disordered relationship with food, which in my experience can last for many years.
For example, dairy is a major source of iodine in many diets. Iodine is essential for thyroid health and early pregnancy development. Similarly, removing whole grains without replacing them properly can reduce fibre intake. Fibre supports gut health and hormone metabolism. Over restriction can also increase stress around food. Feeling anxious about what you can and cannot eat is not helpful during the fertility journey. For this reason, fertility nutrition should focus on building a supportive diet rather than creating unnecessary restrictions.
What a Fertility Supporting Diet Should Focus On
Instead of asking only “Should you cut gluten and dairy when trying to conceive?”, a more helpful question is:
What foods should we prioritise for fertility?
A balanced fertility diet usually includes:
• Plenty of vegetables and fruit
• High quality protein such as fish, eggs, poultry, beans, and lentils
• Healthy fats from olive oil, nuts, seeds, and omega 3 rich fish
• Whole grains including oats, quinoa, and brown rice
• Fermented foods that support gut health
Protein intake is particularly important. Protein supports egg development and hormone production.
Anti inflammatory foods can also support reproductive health. These include leafy greens, berries, omega 3 fats, and colourful vegetables. Often, improving overall diet quality has a greater impact than removing specific foods.
Conclusion
So, should you cut gluten and dairy when trying to conceive? For many women, the answer is no. These foods can be part of a healthy fertility diet and provide important nutrients. However, individual responses vary. Some women with digestive symptoms, inflammation, or specific conditions may benefit from reducing them.
The key is a personalised approach. Fertility nutrition works best when it supports your body, your symptoms, and your nutritional needs.
There is no single fertility diet that works for everyone. While gluten and dairy can cause problems for some people, they are perfectly suitable for many others. If you are trying to conceive, focus first on building a nutrient rich, balanced diet. This supports egg quality, hormone balance, and overall health.
If symptoms suggest a food sensitivity, working with a practitioner such as myself can help identify the right dietary approach. Often the most powerful changes are simple, sustainable improvements to overall diet quality.
