You should eat cooked cauliflower rather than raw: uncooked cauliflower contains a substance which, when ingested raw, could slow down the function of the thyroid. It is therefore inadvisable to it raw, especially for those suffering from hypothyroidism.
Cauliflower is rich in vitamin C, iron, phosphorus, folic acid and potassium. It therefore has the following potential properties: anti-cancer, antioxidant, anti-inflammatory and so on. So, let's get more cauliflower in our winter diet!
