Drinking coke might not be hazardous to health if you stick to consuming the recommended amount of caffeine. Also, the drink does not have any nutrition, and the caffeine present in coke becomes difficult to be digested by the fetus. Therefore, excess consumption of coke might lead to side effects.

Read the post to learn about the safety of consuming coke during pregnancy, the permitted dosage of caffeine for pregnant women, and the side effects of drinking excess coke.

What Is Coke And How Is It Made?

Wikipedia defines Cola as a beverage that has been carbonated and flavored. Traditionally, the Cola constituted of caffeine from Kola Nut, cocaine from Cola leaves, and vanilla as the flavoring agent. However, now cocaine usage has been stopped, and even flavoring extends beyond the vanilla flavor. And that’s the reason you now see all varieties of drinks available in the market.

Preparation of Coke is pretty simple, the machines fill the clean bottle with water, and then sugar is added. The machine then mixes the sugar water with a secret formula [whose recipe, ingredients, and the proportion are known to very few companies] and is topped with some caramel coloring. Finally, carbon dioxide is added to the mixture, to make the drink fizzy and then bottled up (1).

Is drinking coke during pregnancy Safe?

To answer it in one line, yes it is safe if you restrict the consumption of caffeine up to 300mg per day. But limiting does not guarantee that its side effects are now nil. Mostly caffeine, takes a bit longer in getting digested, and as pregnancy progresses, even the breaking down of caffeine slows down, exposing the fetus to ill effects of caffeine.

Drinking coke during pregnancy might not be a good option as it does not offer any nutritional value, and the calories which you keep on sipping are considered to be empty calories. And we all know, how important it for a pregnant woman to take a balanced and nutritious diet. So limiting the dose is crucial.

The Side Effects Of Exceeding The Permissible Limit Of Coke

Caffeine present in the coke, which is present in a woman’s body in the indigestible form, reaches through the placenta, and and the baby absorbs it completely. Studies have shown that the body of a pregnant woman, caffeine is present up to 11 hours. But the fetus can retain it until 100 hours, for the simple reason that they are developing babies and don’t have necessary enzymes to detoxify and break down caffeine.

For the pregnant woman, if she is exceeding the daily measure of coke, it could result in:

  • Dilated pupils
  • Opening of bronchial tubes
  • Increase in heart rate
  • Higher blood pressure

What Are The Sweeteners And Preservatives Added To Coke?

Don’t be fooled by Zero sugar or diet coke labels which give the impression that they don’t have sugar. Most of the aerated soft drinks comes soft drinks come with artificial sugars. And studies have shown that these sweeteners, flavoring agents, preservatives are not advisable for a pregnant woman.

Some of the commonly used sweeteners are:

  • Aspartame (NutraSweet) – It is a safe sweetener, but you should consume it in a moderate quantity. In fact, studies have shown that a pregnant woman should avoid this sweetener as it could also cause depression or chronic pain.
  • Sucralose (Splenda) – This is just a modified version of table sugar and pretty much safe during pregnancy (1).
  • Saccharin (Sweet and Low) – This sweetener can cross the placenta and is considered to be safe for the baby but again you should be taking it in a moderate quantity.

Do You Wish To Get Away With Coke Cravings?

Pregnancy makes a woman crave many things, but she needs to know which things are safe to indulge in. It is not easy to kick the habit! But you need to remember you need to cut it down for the sake of your baby. So look out for these options as an alternative, and if you still feel the urge, sip it and keep it within safe limits. Drink it occasionally and not regularly.

  • Cut the caffeine slowly. Don’t just hash it.
  • Look for options which have no caffeine like Decaf Coffee.
  • Exercise, to fight against the withdrawal symptoms and keep yourself refreshed.
  • Drink lots of water and healthy fluids.

Food Items To Try Out:

  • Fresh fruit juice
  • Lime water
