| Why It Matters for PCOS | |
| Steel-cut and rolled oats deliver beta-glucan, a soluble fiber that slows digestion, improves insulin sensitivity, and steadies blood sugar in PCOS. The cautions are portion size and avoiding instant or sugary flavored oats, which spike glucose faster. Pairing oats with protein and fat keeps the blood sugar response gentle. | White sugar is pure fast-absorbing carbohydrate with no fiber or nutrients, so it spikes blood sugar and insulin immediately, directly worsening the insulin resistance at the core of PCOS. Frequent sugar also fuels inflammation and androgen-driven symptoms. Cutting added sugar is one of the highest-impact PCOS changes you can make. |

If you enjoy White Sugar, consider having it occasionally in small portions paired with protein and fibre to minimise its impact on blood sugar and hormones. But for regular consumption, Oats is the way to go.
