It is not recommended to drink cola during menstruation. First of all, many colas are cold drinks, and if frozen food is drunk during menstruation, it leads to abnormal contraction of the uterus, and menstrual pain and abnormal menstrual flow. Secondly, cola is a carbonated beverage, containing more gas, which can cause gastric distension or stimulate gastric acid secretion after drinking, resulting in stomach pain and discomfort, affecting menstrual appetite and not conducive to the absorption of nutrients. Finally, cola contains a phosphoric acid substance, which affects the absorption of iron, thus affecting the production of blood. Women lose some blood during their periods, which can easily cause anemia, and if they drink a lot of cola during their periods, it will further aggravate the symptoms of anemia. Regardless of whether it is menstruation or usual, it is not recommended to drink Coke, Sprite and other carbonated beverages, and do not eat spicy and stimulating, cold and cold food, which can easily cause adverse effects on the body.
