Sausages should not be eaten more. However, if we can eat more fresh vegetables such as bean sprouts, Chinese cabbage, green peppers, cucumbers, garlic bolts, etc. while eating sausages, or eat fresh fruits such as oranges, fresh dates, tomatoes, grapes and pears after eating sausages, we can eliminate the harm of carcinogens to human body. This is because in vegetables and fruits, the content of vitamin C is extremely rich. Vitamin C can block the combination of sodium nitrite and amine, thus avoiding the formation of strong carcinogens in the digestive tract.
