Polenta is not an easy large keto side using the stored estimate of 70.6g net carbs per 100 g. A 10 g allowance of that concentrated reference contributes about 7.1g within a 20–25 g daily budget. The preparation basis is underspecified, so this is an arithmetic illustration, not a verified serving of cooked soft polenta.

WHY IT'S NOT KETO-FRIENDLY
- Separate dry polenta meal from ready-cooked polenta sold in a tube. Their water content and labeled serving basis differ, and this generic record should not be assigned to either without checking the package.
- For homemade soft polenta, record the dry ingredient, liquid and added cheese before cooking. Divide the finished batch rather than applying a dry-style value directly to a spoonful of cooked porridge.
- Grilled polenta slices and soft polenta in a bowl are different prepared portions. Count any oil, sauce or coating in addition to the original recipe ingredients.
PREPARATION SUGGESTIONS
USE A DIFFERENT SAVORY BASE
For a sauce-bearing side, choose a prepared vegetable base and count the sauce independently. The texture will change; do not assume cornmeal simmering times apply to a vegetable substitute.
Better keto swaps
- Cauliflower Rice — 3g net carbs per 100 g (reference). For a savory bowl, use cauliflower as a vegetable base under the sauce. It will not reproduce a smooth corn porridge.
- Yellow Squash — 2.9g net carbs per 100 g (reference). A cooked squash side can carry the same savory topping when a soft vegetable texture suits the dish; use its own reference and preparation.
