People who suffer from inflammation caused by lactose, gluten, or soy will find advantages to following dairy-free, gluten-free, or soy-free PCOS diets. However, in regards to a PCOS diet, no scientific data currently exists to support restricting or avoiding entire food groups or specific items to improve symptoms.
PCOS and Inflammatory Conditions
The theory goes like this: PCOS is associated with low-grade inflammation. So, to help alleviate PCOS symptoms, focus on treating the inflammatory conditions directly. The CCRM Fertility Center recommends eating antioxidant rich foods to relieve minor inflammation. While we believe that this is supportive of overall health, antioxidant foods cannot "cure" PCOS. Instead, dairy-free diets can directly treat lactose-related allergies and sensitivities, while gluten-free diets can benefit those people with Celiac Disease.
Does Dairy Matter?
Various studies have investigated a potential link between diary consumption and fertility disorders. This comprehensive scientific review did not find a significant connection between dairy consumption (mostly, milk) and PCOS. The scientific reviews and number crunching are mixed at best.
Truthfully, scientists have been trying to nail down the cause of PCOS for a long time, with little success. Some studies suggest an indirect link between dairy consumption, obesity, and PCOS. However, there is no clear connection between these topics.
You may have read about the link between dairy and acne, which is a common PCOS symptom. The two conditions are often observed together because some type of acne are caused by androgen, a natural chemical that that is released from eating dairy products. Reducing dairy may alleviate acne, but there is no proven link between restricting dairy and improving your PCOS.
As you may expect, research linked to infertility is a popular topic, ranging from these diet-based investigations to chemicals and pesticides.
Fertility and Dairy
Yep, scientists have studied this relationship as well. A study by Chavarro et al. suggested that high-fat dairy products can promote fertility. If you are trying to get pregnant, you may want to discuss this aspect of your diet with your doctor or dietitian. Many people associate dairy with calcium. For people who limit dairy in their diets, due to allergies or acne-related side effects, there are numerous non-dairy Calcium sources. The PCOS Nutrition Center lists kale, broccoli, bok choy, salmon, seeds, and quinoa as excellent sources of calcium.
If dairy does not contribute to PCOS, what can I do?
We know that to improve PCOS symptoms, it helps to lose 5-10% of your body weight and and exercise regularly. Your dietitian will be able to work with you to determine a specific PCOS diet to optimize your health. The combination of improving your food choices, being more active, and working with a dietitian and your doctor can be the jump-start you need!
