It’s critical to avoid high sugar foods in PCOS. Eating less sugar can help lower blood glucose levels. This decreases insulin levels, and reduces male hormone levels. Most women with PCOS crave sugary foods, even after eating meals. This is due to increases in insulin. To best manage insulin levels, cut down the amount of simple carbs in your diet by cutting down packaged foods with added sugars, cold drinks, packed juices, refined cereals etc.
