PCOS Basics and Nutrition

PCOS Effects on the Body

Polycystic ovary syndrome (PCOS) disrupts hormones and impacts various body systems. Insulin resistance, a common issue with PCOS, hinders glucose processing and raises androgen levels, which can affect fertility and metabolism.

Around 70% to 80% of women with PCOS face fertility challenges [6]. Additionally, more than 70% experience excessive hair growth on the face and body [6]. PCOS can also prevent regular egg release, leading to irregular menstrual cycles.

"Health optimization in people with PCOS is sensitive to a lot of things - especially the things we eat and drink, our sleep-wake cycle, and physical activity." [2]

This makes nutrition a key factor in managing PCOS effectively.

Key Diet Targets for PCOS

Diet plays a major role in addressing the hormonal imbalances caused by PCOS. Over 50% of women with PCOS develop diabetes or prediabetes before the age of 40 [1][4], and up to 70% show signs of abnormal cholesterol levels [7].

The Mediterranean diet is often recommended for managing PCOS. Amanda Stathos, M.S., R.D., L.D.N., notes:

"Research shows that people with PCOS show evidence of all-over inflammation, which is associated with heart disease and other illness. The Mediterranean diet eliminates saturated fats, processed meats and refined sugar, which makes it a powerful tool to address inflammation." [3]

By tailoring your diet, you can address these issues and improve your overall health.

Here are some key dietary strategies:

Target Area Goal Primary Approach
Blood Sugar Control Stabilize insulin levels Pair carbohydrates with protein and fiber
Inflammation Reduction Minimize inflammation Focus on whole, unprocessed foods
Hormone Balance Support hormone health Include healthy fats and lean proteins

Timing meals around physical activity can also help regulate blood sugar levels [2].

Best Foods for PCOS

Protein Sources

Boosting your protein intake from 15% to 30% of daily calories can help manage PCOS symptoms and promote fat loss over time [8]. Protein-rich foods are great for stabilizing blood sugar and supporting hormone health.

Protein Type Examples Benefits
Lean Animal Proteins Chicken breast, turkey, fish Full amino acid profile, low in saturated fat
Seafood Shrimp, tuna, salmon High in omega-3s, aids hormone balance
Plant-Based Tofu, lentils, quinoa Fiber-rich, helps regulate blood sugar
Dairy Alternatives Greek yogurt, cottage cheese Packed with calcium, supports weight control

High-Fiber and Low-GI Foods

With 50% to 75% of people with PCOS experiencing insulin resistance [3], focusing on high-fiber, low-glycemic foods is key. These foods help keep blood sugar steady and assist in flushing out excess hormones [9].

"Insulin is like a key that opens cells and lets glucose in... in people with insulin resistance, the insulin does not convey glucose into the cells properly." - Amanda Stathos, M.S., R.D., L.D.N. [3]

Add these high-fiber options to your meals:

  • Whole grains like brown rice, quinoa, and barley
  • Legumes such as lentils, beans, and peas
  • Vegetables like leafy greens, broccoli, and cauliflower
  • Fruits like apples, berries, and citrus

Healthy Fats for Hormones

Monounsaturated and polyunsaturated fats are essential for hormone balance [4]. Include these in your diet:

  • Avocados: Packed with heart-healthy fats
  • Olive Oil: Use as your go-to cooking oil for its anti-inflammatory properties
  • Nuts and Seeds: Almonds, walnuts, and pumpkin seeds are great choices
  • Fatty Fish: Salmon and mackerel are recommended twice a week for their omega-3s

These fats not only support hormones but also contribute to overall health.

Foods That Help Reduce Inflammation

Chronic inflammation is a common concern with PCOS and can lead to other health issues. Incorporate these anti-inflammatory foods into your diet:

  • Berries: Loaded with antioxidants
  • Green Tea: Contains polyphenols that combat inflammation
  • Leafy Greens: Full of essential vitamins and minerals
  • Turmeric: Known for its active anti-inflammatory compounds
  • Omega-3 Rich Fish: Helps regulate menstrual cycles [4]

Foods to Limit with PCOS

Sugar and Simple Carbs

Keeping blood sugar levels stable is a priority for managing PCOS due to high insulin resistance [3]. Research published in Fertility and Sterility found that women on a low-glycemic load diet for 12 weeks saw a 20% boost in insulin sensitivity and a 35% improvement in menstrual cycle regularity, compared to those on standard diets.

Hereā€™s a quick guide to what to avoid and what to choose instead:

Food Category Avoid These Choose These Instead
Breakfast Foods White bread, pastries, sugary cereals Whole grain toast, steel-cut oats
Beverages Sodas, fruit juices, sweetened coffee drinks Water, unsweetened tea, coffee
Snacks Candy, cookies, crackers Fresh fruit, nuts, seeds
Grains White rice, white pasta, instant noodles Brown rice, quinoa, whole wheat pasta

Processed foods can make things worse, too, so itā€™s worth keeping an eye on those.

Processed and Fried Foods

Foods that are processed or fried can aggravate PCOS symptoms by increasing inflammation and introducing harmful trans fats [3][5]. Common culprits include:

  • Pre-packaged meals and snacks
  • Fast food items
  • Deep-fried foods
  • Processed meats like hot dogs, bacon, and deli meats

Cutting down on these can help reduce inflammation and improve overall symptoms.

Full-Fat Dairy Products

Dairyā€™s role in PCOS management can be tricky. According to the Nurses Health Study II, adding one serving of whole milk daily reduced ovulatory infertility by over 50% [10]. However, some women with PCOS may react poorly to dairy, depending on the type of casein protein it contains. A1 casein, found in most commercial dairy, may trigger inflammation, while A2 casein (from Jersey cows, goats, or sheep) could be easier to tolerate [11].

Here are some better dairy options to consider:

Dairy Type Why It Helps Examples
Fermented Easier to digest, lower in lactose Greek yogurt, kefir
A2 Dairy Less likely to cause inflammation Milk from Jersey cows, goats, or sheep
Plant-Based Free of common allergens Soy milk, pea milk

Inflammatory Triggers to Avoid

Inflammation can disrupt insulin sensitivity and ovulation [11]. Dr. Lara Briden, ND, emphasizes:

"After 18 years of treating PCOS, I am convinced that inflammation is the major underlying cause for many types of PCOS" [11].

To minimize inflammation, steer clear of:

  • Gluten-containing foods (if sensitive)
  • Pesticide residues from non-organic produce

Making thoughtful food choices can go a long way in managing PCOS symptoms effectively.

Restaurant Ordering Guide

Eating out doesn't have to derail your PCOS plan. With a few adjustments, you can make restaurant meals work for you. Here's some expert insight:

"Women with PCOS can enjoy alcohol, especially red wine which may help improve many aspects of the condition, however, cocktails tend to be full of juices and other sugary components which can quickly spike up glucose and insulin levels." [12]

Smart Ordering Strategies:

  • Check menus online in advance to find suitable options
  • Opt for grilled or steamed dishes instead of fried foods
  • Request vegetables without butter or heavy seasoning
  • If drinking, choose red wine over sugary cocktails

Menu Navigation Tips:

  • Look for terms like "grilled", "steamed", "roasted", or "broiled"
  • Avoid dishes labeled "crispy", "breaded", or "creamy"
  • Substitute refined carbs with extra vegetables
  • Ask for sauces and dressings to be served on the side
