How each berry fits the four PCOS subtypes
Strawberries
Strawberries are about as uncomplicated as fruit gets for PCOS: a glycemic index near 40, a glycemic load of roughly three per cup, three grams of fiber, and a generous dose of vitamin C and anthocyanins. They fit every subtype comfortably, and are as good eaten by the handful as they are on yogurt.

- Post-Pill PCOS: Good fit
- Inflammatory PCOS: Good fit
- Lean PCOS: Good fit

Blueberries
Blueberries are one of the more straightforward good-news foods here — a low glycemic index, a modest load per cup, real fiber, and the anthocyanin polyphenols that give them their color. They suit all four PCOS subtypes, and frozen berries carry the same profile as fresh at a fraction of the price.

- Post-Pill PCOS: Good fit
- Inflammatory PCOS: Good fit
- Lean PCOS: Good fit

Blackberries
Blackberries are one of the most fibre-dense fruits available — a cup carries more fibre than available carbohydrate. That structural fact, not a vague 'berries are good' claim, is why they sit at the gentle end of the fruit spectrum for PCOS. They've never been formally GI-tested, so no GI or GL number exists for them.
- Insulin-Resistant PCOS: Good fit
- Post-Pill PCOS: Good fit
- Inflammatory PCOS: Good fit
- Lean PCOS: Depends

Raspberries
Fresh raspberries have never been glycemic-index tested — any GI number you see online for them isn't real. What's verified is the ratio: a 125g cup carries about 6.4g available carbohydrate against 4.6g fiber, so most of that carbohydrate is fiber your body doesn't absorb as sugar. That ratio, not a made-up GI number, is the real story here.

Reading these numbers
Glycemic index (GI) ranks how quickly a food's carbohydrate raises blood glucose compared with pure glucose. Glycemic load (GL) multiplies that by the carbohydrate in a real serving, so it is usually the more useful number for an actual plate. Foods with little carbohydrate have no GI assigned at all. Servings differ between foods, and cooking method, portion size and what you eat alongside all change the real-world effect.
This page compares Peach's individual food guides side by side. It isn't medical advice, and a clinician or registered dietitian can help you fit these foods to your own plan.
Portion size changes glycemic load. Estimate the glycemic load of your own serving, or check any other food in the PCOS glycemic index table.
