The good thing about cauliflower is that moderate consumption can provide the body with protein, vitamins, minerals and other nutrients; the bad thing is that if you eat fresh cauliflower may cause toxic reactions. Cauliflower is rich in protein (19.4g/100g) and can be a good source of protein. Cauliflower is also rich in vitamins and minerals, such as thiamin 0.05mg per 100g of cauliflower, riboflavin 0.21mg, 3.10mg of niacin, 301mg of calcium, 216mg of phosphorus, 610mg of potassium, 85mg of magnesium, 8.1mg of iron, 3.99mg of zinc, 4.20μg of selenium. Moderate consumption of yellow cauliflower can supplement the body with the above mentioned substances, which has a certain nutritional value. However, it should be noted that fresh cauliflower contains colchicine, which can cause gastrointestinal toxicity, must be processed and dried, eat first with boiling water, and then soaked in cool water, so as not to cause harm to the human body.
