Cauliflower is a vegetable, and the figures here describe frozen cauliflower boiled in unsalted water. It provides small amounts of carbohydrate and protein, along with vitamins and minerals. Per 100g, it contains 2g of carbohydrate, 2g of protein, 31mg of vitamin C and 210mg of potassium.

Vitamin C supports normal immune function and helps the body absorb iron from plant foods. Potassium contributes to normal muscle and nerve function. This preparation contains little salt or saturated fat, which may be relevant to people monitoring their intake. Adding salt, butter or sauces changes the nutritional content of the finished dish.

About these figures

Values are per 100g of the food as described (10 samples, 10 brands; boiled 4-9 minutes). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.

These figures come from an older part of the dataset that is no longer updated. Original source: LGC, Frozen vegetable survey, 1985.
