Pregnant Woman Drinking Coke

Most women may be apprehensive about drinking coke during pregnancy because they are unsure of its safety. Coke is a carbonated drink with caffeine and sugar. It does not have much nutritional value.

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 and elevate the risk of health issues like diabetes and heartburn.

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?

Coke is prepared by mixing water, sugar, caffeine, and carbon dioxide

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.

protip_icon Did You Know?
The name Coca-Cola comes from the original recipe created in the 19th century by pharmacist John Pemberton (8).

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 soft drink fizzy and then bottled up (1).

Nutritional Value Of Coke

So Coke mainly consists of

  • Sugar
  • Carbon Dioxide – making it acidic in nature
  • Caffeine
  • Artificial Sweeteners
  • Preservatives

Let’s look at the sugar and caffeine value of some of the common drinks (2):

Drink NameSugar Content [g/100ml]Caffeine Content [mg]
Coca-Cola [Classic]11.134.0
Pepsi [Classic]11.437.5
Sprite10.30.0
Mountain Dew12.055.0

Is Drinking Coke During Pregnancy Safe?

Drinking coke during pregnancy is safe if you limit caffeine consumption

To answer it in one line, yes, it is safe if you restrict caffeine intake to 300mg daily. 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 unborn baby to the 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 is for a pregnant woman to take a balanced and nutritious diet. So limiting soda consumption is crucial.

The Side Effects Of Exceeding The Permissible Limit Of Coke

Excess coke can result in miscarriage and insomnia

Caffeine present in the coke, which is present in a woman’s body in the indigestible form, reaches through the placenta, and the baby absorbs it completely. Studies have shown that in the body of a pregnant woman, caffeine is present for 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
  • Discharge of insulin into the blood stream from the liver
  • Tightened muscles
  • Higher metabolism
  • Could result in Miscarriage
  • Reduced Fertility
  • Diuretic in nature and makes our body lose water.
  • Insomnia

Also, for the fetus it has an adverse effect as it could lead to:

  • Birth Defects
  • Pre-Term Delivery
  • Low Birth Weight

What Are The Sweeteners And Preservatives Added To Coke?

Most soft drinks come with artificial sugars

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 come with artificial sugars. Studies have shown that sweeteners, flavoring agents, and preservatives are not advisable for pregnant women. Moreover, consuming excessive amounts of sugar in pregnancy might increase your risk of developing gestational diabetes.

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 is 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.

A research study suggests that consuming artificial sweeteners during pregnancy may increase the risk of obesity in the unborn child. The study also says that these sweeteners can alter gut bacteria, which could contribute to the risk of obesity (9).

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 to cut down on caffeinated drinks to ensure proper fetal growth and development. 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 to avoid the adverse effects of cold drinks during pregnancy.

  • 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
  • Lassi [sweet and salted]
  • Aam pana or raw mango water
  • Coconut water
  • Homemade smoothies

Marie, a mother, wardrobe stylist, and actor, shares her take on soda during pregnancy. She says, “I have completely cut out diet pop, which was very hard for me but I did it and my guts thank me, but sometimes I will have a Coke as a treat. That’s all I drink for caffeine. But I mostly drink water with lemon (i).”

Frequently Asked Questions
