PCOS and Food

If you have Polycystic Ovarian Syndrome (PCOS), you may think nothing can be done to treat your condition. After all, there’s not even a definitive test to diagnose it! Most treatment plans focus on treating specific symptoms with many doctors recommending lifestyle changes or, in some cases, hormonal birth control. But did you know that changing your diet can help manage some of the long term symptoms of PCOS? No crash diets or crazy medication needed - just some slight changes to your diet is sometimes all that’s required to relieve some of the worst symptoms.

In this post, we will tell you all about PCOS, the best nutrition tips for managing PCOS, foods to eat and foods to avoid.

What is PCOS?

First of all, what is PCOS? Most women discover they have PCOS because they struggle with irregular periods or no periods at all. Women with PCOS usually have cysts on their ovaries which are caused by too much of a hormone called androgens. Unfortunately, there is no specific test to diagnose PCOS, so doctors typically start with a discussion of medical history including your menstrual periods and any weight changes. Weight is important because research shows that between 33 and 83% of women with PCOS are also overweight or obese. That said, women with a healthy weight can also have PCOS so it is not the only indicator.

What are the symptoms of PCOS?

In addition to weight changes or weight challenges, women with PCOS may also struggle with excess hair growth (or in some cases, hair loss or thinning hair) insulin resistance, oily skin and acne. Women with PCOS may struggle to get pregnant, and they are also at a greater risk of developing heart disease, endometrial cancer, diabetes and high blood pressure. If you’ve recently received a diagnosis for PCOS, it can be a bit scary, but don’t worry. We’ve got your back and there are ways to manage your symptoms without medication or radical lifestyle changes.

Guud Woman founder Morgane struggled with PCOS. After she stopped taking the pill, her periods were irregular and she also had severe mood swings and hormonal acne.

“It didn't feel right, so I went to the doctor,” she said. “He told me I had PCOS. When I asked what I could do about it, he said there was nothing. And there I was. Not even thirty, and already 'something was wrong' with me: I had health problems and had reduced fertility.”

Morgane learned that you can improve PCOS symptoms with nutrition and lifestyle changes. If you want to know more about her experience, you can read about it here.

What causes PCOS?

Unfortunately, the exact cause is not known. Some research indicates that genetics play a role, but other factors include higher levels of androgens, a male hormone which prevent the ovary from releasing eggs. This is what disrupts your menstrual cycle and causes irregular periods (or for some women, no period at all!)

Lifestyle choices can also play a role in PCOS. What you eat, how active you are and your levels of stress all impact your menstrual cycle. While it’s difficult to pinpoint any one cause, it’s important to know that all aspects can impact your cycle and make PCOS symptoms worse.

How does your diet impact PCOS?

One common thing in women with PCOS is that they often have high levels of insulin, a hormone produced in your pancreas. Ordinary levels help turn sugar into energy, but if you have too high levels of insulin, it can result in something called insulin resistance. This means that you can’t use the insulin you produce effectively. This can cause your ovaries to produce more androgens, a male hormone like testosterone. Insulin resistance may also be caused by having a higher body mass index (BMI) and it can make it harder to lose weight which is why so many women with PCOS struggle with their weight.

So the short answer is that diet contributes significantly to insulin resistance so if your body is already struggling, you can give it a bit of a leg up by limiting certain foods. According to research, diet plays a really important role in managing symptoms of PCOS. When women altered their diets, it helped eliminate negative symptoms of the condition.

Can food relieve symptoms of PCOS?

Yes! It definitely can! So if you’re part of the PCOS club, we’re glad you’re here because if you start making some changes to your diet, we’re confident you’ll see some results.

As we mentioned, PCOS can cause insulin resistance so it’s important to add some foods that combat this condition. Foods high in fiber are the key - they help slow down digestion and reduce the effect of sugar on the blood.

Here’s some examples of some high fiber foods to try:

  • Veggies like cauliflower and broccoli
  • Leafy greens like kale, spinach and other dark leafy goodness
  • Beans and lentils
  • Berries
  • Sweet potatoes
  • Green and red peppers
  • Nuts like almonds, pine nuts and walnuts
  • Pumpkin and sweet potato

A healthy PCOS diet can also include:

  • Lots of natural, unprocessed foods
  • Fatty fish like salmon and tune
  • Healthy fats like olive oil, avocados and coconuts
  • Dark chocolate (in moderation! And make sure it’s at least 75% cacao)

Why Breakfast is the Most Important Meal if you PCOS

Breakfast is important for everyone, but if you have PCOS, it really is the most important meal of the day. By the time you wake up, your body hasn’t had food for at least 8 hours so it is primed to burn fat for energy instead of its own tissues. Breakfast is the first opportunity in the day to fill your body with nutrients that will keep you powered-up for the day and as a result, you’re more likely to be able to avoid unhealthy snacks or sugar which is especially bad if you have PCOS. Eating in the morning also helps improve insulin sensitivity and maintain steady energy levels over the course of the day.

Foods to avoid if you have PCOS

In general, the guidance here is to avoid foods that most people would consider unhealthy. Things like:

  • Refined carbs like pastries and white bread
  • Fried foods
  • Soda and energy drinks full of sugar
  • Processed meat like hot dogs, sausages and lunch meat
  • Red meat
  • Alcohol in excess
  • Coffee. Sorry ladies. Research shows that women who drink more than two cups of coffee per day have higher levels of estrogen during the follicular phase of their cycle. This is especially challenging if you have PCOS because you’ll already have trouble balancing your hormones during this phase.

Of course, indulge in that croissant or BBQ’d steak from time-to-time (we’re not monsters!), but moderation is key, especially if your PCOS symptoms are severe.

Is dairy bad for PCOS?

You may have heard that dairy is bad for women with PCOS and there is some truth here. Dairy products contain a hormone called insulin-life growth factor (IGF-I) which increases androgen production in women when we eat things like milk or ice cream. Many dairy products are also super high in sugar which is also something women with PCOS should avoid because sugary foods cause insulin levels to spike and then drop. This causes a cycle of highs and lows that women with PCOS are more likely to experience because their bodies can’t easily regulate blood glucose levels and this can lead to inflammation.

Best supplements for PCOS

Changing your diet is a great way to help combat PCOS symptoms, but it is hard to get all the nutrients you need through food alone. That’s where supplements come in. Try a multivitamin like Guud Flow. It is specially formulated to help regulate your hormones, promote a healthy cycle and support your fertility. Combine this with Guud Inside and Guud Vibes. 

  • Guud Inside contains sustainable omega-3 made from algae. Studies have shown in omega-3 fatty acids,  can help increase the quality of your eggs and your ovarian reserve which is important for ovulation.
  • Guud Vibes contains high-quality magnesium and vitamin B6. These ingredients helps regulate your hormonal activity and support your cortisol levels.
