Cola is not recommended in early pregnancy. Most cola-type beverages contain caffeine, which can easily enter the fetus through the absorption of the placenta. After caffeine enters the bloodstream, it can be passed on to the fetus through the placenta. Excessive caffeine intake can pose certain risks to the health of the fetus, jeopardizing the fetus’s brain, heart, and other vital organs, and causing the fetus to be malformed or suffer from congenital dementia. It has been reported that if the intake of caffeine exceeds 300-450mg a day, it may cause underweight of the fetus. Moreover, cola-type drinks are high in sugar, and the World Health Organization recommends that adults and children should reduce their daily intake of free sugars to less than 10 percent of their total energy intake, preferably to less than 5 percent. The sugar used in cola is a common free sugar, and drinking more of it will increase your sugar intake, so you should reduce your cola intake.
