Harmful Effects of Soft Drinks During Pregnancy?

Fizzy drinks or carbonated drinks are loaded with excess sugar and very few nutrients, which means you must keep their consumption at a minimum. You should also be aware of why taking such drinks on a regular basis is harmful to you.

1. Presence of caffeine

One of the sole reasons why you should avoid drinking soft drinks during pregnancy is that it contains caffeine. Studies conducted by the American Pregnancy Association reveal that pregnant females who consume over 200mg of caffeine a day, are twice as likely to experience a miscarriage. Moreover, caffeine may also cause high blood pressure, birth defects, preterm labor, premature delivery, reduced fertility, and low birth weight, and other reproductive problems as well (1). Hence, it is essential that you limit the intake. Moreover, caffeine can also deprive you of sleep and deplete the calcium levels in your body (2). Caffeine also has a diuretic effect on the body, meaning they may increase urine production and contribute to dehydration if consumed in excess. Hence, it is essential to limit your daily caffeine consumption within the recommended levels.

Every 350ml (12 oz) of carbonated drinks may contain 30 to 55mg caffeine (7).

 2. Added colors and artificial sweeteners

Though a small percentage of artificial ingredients would not harm your baby’s health, studies reveal that huge amounts of soft drinks that have artificial flavors or colors are not advisable. Also, the presence of saccharin in some soft drinks may be harmful to the fetus owing to its carcinogenic properties (3).

A few studies indicate that aspartame or sucralose is not harmful if consumed in small amounts by pregnant mothers. In addition, regular or excess consumption of soft drinks during pregnancy can raise an expecting woman’s risk of developing gestational diabetes. This risk increases multi-folds if the mother already has type-1 or type-2 diabetes.

So, make sure to read the label of the soft drinks that you buy to make sure that there are no harmful ingredients that are not good for your baby.

3. Zero nutrition and unhealthy calories

Soft drinks offer very little or no nutrition, which means that they add no value to the well-being of a pregnant mother (4). But these drinks can hike your body’s calorie levels. In short, these carbonated drinks would not offer any vitamins or minerals, which are much needed for the fetal growth and development. If you are obsessed with fizzy stuff, a sip or two of your favorite soda occasionally would not do any harm.

Drinking carbonated drinks during pregnancy can cause heartburn or make it worse if you already have it, especially during the third trimester (5). If you experience a burning sensation across the chest region or just below your throat after a few minutes of consuming any aerated drink, refrain from drinking it.

Frequently Asked Questions

1. Is it okay to drink coke while pregnant?

You may drink clear water and other healthy liquids than the drinks packed with extra sugars, caffeine, and artificial flavors and colors. It is not a healthy choice for pregnant women to drink artificially sweetened beverages. According to a study, people who consume diet sodas gain excess weight (6). In addition, some studies found that artificially sweetened drinks are associated with maternal obesity, resulting in increased fetal weight or heavy babies. Hence, limiting your total sugar intake from different foods and beverages, including soft drinks, is beneficial.

2. How often can you have soft drinks while pregnant?

Occasional intake of sweetened soda or lemonade is not a concern, especially for mothers who follow a healthy balanced diet and regular exercise. You may drink liquids without added sugars to avoid getting empty calories. Also, keep an eye on the caffeine content and other added flavors (6).

3. Which cool drink is good for pregnant women?

Pregnant women need to stay hydrated, and cool drinks such as cold water, coconut water, iced teas, and cold fruit juices can be a refreshing way to do so.

4. Can pregnant people drink Coke Zero (diet soda)?

Research shows that if expecting mothers consume excessive artificial sweeteners-laden diet soda, they may deliver heavier babies (9). The artificial sweeteners used in Coke Zero are aspartame and acesulfame potassium (10). When consumed in moderation, the FDA considers these sweeteners to be safe during pregnancy (11).

5. Why does my baby move when I drink cold water or drink?

Babies in the womb may respond to stimuli in their environment, such as changes in temperature and sound (12). Therefore, you may feel your baby moving in the womb when drinking cold water or drinks. However, this response may or may not occur in all babies.

Having occasional cold drinks will not harm you or your baby. However, ensure that you don’t drink them frequently as cold drinks are high in unhealthy ingredients, such as sugar and caffeine, and may contain additives that can adversely affect you and your unborn baby. Thus, making yourself a fresh lemonade or chilled fruit smoothie is ideal if you crave a cold drink. Consuming these healthy alternatives to cold drinks will refresh you, provide several nutrients, and keep you away from the ill effects of cold drinks during pregnancy.
