| Why It Matters for PCOS | |
| Most breakfast cereals are refined grains plus added sugar, so they spike blood sugar and insulin early in the day and leave you craving more carbs, which is counterproductive with PCOS insulin resistance. The exception is a genuinely high-fiber, low-sugar cereal like plain oats or unsweetened bran. Always top it with protein and fat to steady blood sugar. | 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. |
