Women with polycystic ovary syndrome (PCOS) are often instructed to eat certain foods to keep their weight down and their hormone levels in check. The truth is, there are no food groups that are entirely off-limits for most women with PCOS. It's just a matter of making the healthiest choices and moderating your intake.

This article helps clear up some of the misconceptions about PCOS and food, and offers guidance about healthy eating for PCOS.

Fruit Is Allowed

Carbohydrates in general get a bad rap, but most fruits (which are carbs) don't deserve it.

Fruits provide important vitamins, minerals, antioxidants, and fiber that offer numerous benefits to women with PCOS.

These benefits include:

  • Improved cholesterol levels: Up to 70% of women with PCOS have high cholesterol.
  • Lower blood pressure: Women with PCOS are 53% more likely to have high blood pressure than women without the condition.
  • Reduced insulin resistance: Insulin resistance is a diminished ability to utilize the hormone insulin to control blood sugar. This problem is common in women with PCOS.
  • Cancer prevention: Women with PCOS are at an increased risk of breast cancer, endometrial cancer, and ovarian cancer.

A study published in the Hormone and Metabolic Research Journal showed that women with PCOS who ate a diet rich in fruits and vegetables lost more abdominal fat, had significant improvements in their responsiveness to insulin (the hormone that helps regulate blood sugar), and had a reduction in inflammatory markers.

Choose fruits with the skin on them (such as apples, blueberries, and strawberries). These tend to have a lower glycemic index (GI) than fruits eaten without the skin, such as pineapple and watermelon. The lower the GI of fruit, the less it will raise blood sugar levels. That being said, you are still better off eating any fruit than a dessert such as a pastry or other refined carbohydrates.

Fruit consumption should be spread out evenly throughout the day. Pair fruit with a protein source (for example, an apple with peanut butter) to help stabilize glucose and insulin levels.

On the other hand, you need to avoid fruit juice because it will quickly spike blood sugar levels.

You Don't Have to Go Gluten-Free

Gluten is a protein found in cereal grains like wheat, rye, and barley. While most women with PCOS can eat gluten without problem, a small percentage may have gluten sensitivity or celiac disease. These are immune-related disorders in which the body responds abnormally to gluten, causing digestive symptoms like diarrhea, bloating, and nausea.

For these women, removing gluten from the diet will reduce digestive symptoms and help them feel better. However, cutting gluten from your diet is not necessary if you don't have gluten intolerance or celiac disease.

Many women with PCOS think that eating gluten-free will help them lose weight. However, there is no scientific evidence to support this. While some women may lose weight by going gluten-free, it's more likely due to eating fewer calories overall.

Focus on eating sensible portions of gluten-containing foods, such as whole-grain bread, along with protein-rich foods that help normalize blood sugar and aid with weight management.

For weight management and to prevent high blood sugars, focus on eating whole rather than refined grains.

Dairy Is Not Off-Limits

Milk is a rich source of calcium, vitamin D, and protein. It is also considered a carbohydrate due to its high lactose content.

An article in the Journal of the Academy of Nutrition and Dietetics showed a link between dairy consumption and acne. It also found that milk, nonfat in particular, can contribute to increased androgen and insulin levels.

Acne can be a problem for people with PCOS, and it is believed to be related to high androgen levels. For these reasons, it may be advisable for some women with PCOS to limit their intake of dairy products,.

Consider consuming just a few servings per week, unless you have a milk allergy or are lactose intolerant, in which case you may need to avoid it altogether.

Dairy offers bone-strengthening benefits, so if you plan to eliminate dairy from your diet, make sure to eat other foods that offer bone-strengthening benefits.

You Can Indulge Your Sweet Tooth

While desserts and other sugary foods aren’t great for PCOS and should be limited, they can be part of a healthy PCOS diet if enjoyed in moderation.

A square or two of dark chocolate (70% cocoa or more) can satisfy a sugar craving. It also contains compounds called antioxidants that help fight free radicals (a type of unstable molecule) that damage cells and tissues.

Sometimes being too restrictive with sweets can backfire and lead to episodes of binge eating. So go ahead and indulge your sweet tooth from time to time, but focus on whole foods with sensible portions as the main component of your diet.

Summary

If you have been diagnosed with polycystic ovary syndrome (PCOS), you will be advised to adjust your diet to better control your insulin and hormone levels. Dietary strategies may also help manage some of the symptoms of this common hormonal disorder.

Overly restrictive diets can cause more harm than good by robbing you of essential nutrients and increasing the risk of binge eating. Sensible eating with moderate portions is key.

This includes eating fruits like apples and blueberries that have a low glycemic index. You don't necessarily need to avoid dairy and gluten; simply limit your intake and choose healthy options (such as low-fat milk and whole-grain bread). An occasional sweet is OK to curb a sugar craving.
