Ketogenic diet needs to pay special attention to the balance of vitamin and mineral intake. In the choice of vegetables, a big basic principle is "eat more vegetables that grow on the ground and eat less vegetables that grow underground". Vegetables on the ground should be selected with high nutritional value and low carbohydrate, such as spinach and cruciferous vegetables (cauliflower). Underground dishes are not completely inedible, such as white radish and onion. Adding them to the soup pot is also a good choice.
