Safety Status: Consume in Moderation
Regular sugar-sweetened soda should be consumed in moderation during pregnancy. While it is not contaminated with pathogens that cause immediate foodborne illness, its nutritional profile consists almost entirely of refined sugars, artificial colorings, and empty calories.
Health organizations, including the World Health Organization (WHO) and the American College of Obstetricians and Gynecologists (ACOG), advise pregnant individuals to minimize their intake of sugar-sweetened beverages. Regular consumption of high-fructose corn syrup or sucrose can lead to rapid weight gain, poor metabolic health, and dental decay.
Gestational Diabetes and Metabolic Risks
The main concern with regular soda during pregnancy is the high volume of simple sugars. A single 12-ounce can of regular soda contains roughly 39 grams of sugar, which is equivalent to about 10 teaspoons of sugar.
When you drink liquid sugar, your body absorbs it almost immediately because there is no fiber, fat, or protein to slow down digestion. This triggers a sharp increase in blood glucose levels, prompting your pancreas to secrete a large amount of insulin.
During pregnancy, placenta-produced hormones naturally cause a degree of insulin resistance to ensure the fetus receives sufficient glucose. Consuming high-sugar drinks frequently can overwhelm this delicate metabolic balance, increasing the risk of:
- Gestational Diabetes Mellitus (GDM): A condition characterized by high blood sugar during pregnancy, which can lead to complications like preeclampsia, cesarean delivery, and neonatal hypoglycemia (low blood sugar in the baby after birth).
- Fetal Macrosomia: Excess glucose in the mother’s blood crosses the placenta, causing the baby’s pancreas to produce extra insulin and store the excess energy as fat. This can lead to an abnormally large baby, increasing birth risks.
- Gestational Hypertension: Excess sugar intake has been linked to increased inflammation and blood pressure spikes.
Caffeine and Chemical Additives
Aside from sugar, regular sodas often contain other compounds that require monitoring:
- Caffeine Tracking: Many popular regular sodas (especially colas and mountain-themed sodas) contain caffeine. A 12-ounce can contains between 35 and 55 mg of caffeine. While this is well below the 200 mg daily limit recommended by ACOG, drinking multiple cans of soda alongside coffee or tea can push you over the safe threshold.
- Phosphoric Acid: Frequently added to dark sodas for flavor, phosphoric acid can interfere with the absorption of calcium in the digestive tract. Since calcium is critical for your baby’s developing bones, excessive soda intake can compromise maternal bone health.
Healthy Alternatives
To satisfy the craving for bubbles and sweetness safely:
- Seltzer with Juice: Combine carbonated water with a splash of 100% pasteurized cranberry, pomegranate, or orange juice. This provides carbonation and flavor with minimal sugar and extra vitamins.
- Fruit-Infused Sparkling Water: Infuse plain sparkling water with fresh strawberries, raspberries, or mint leaves.
- Caffeine-Free Sodas: If you must drink soda, choose caffeine-free varieties and limit consumption to occasional treats.
Safe Alternatives
Seltzer water with a splash of 100% pasteurized fruit juice, naturally flavored sparkling water, or iced herbal teas.
OB-GYN Clinical Tip
Regular soda is high in refined sugar and empty calories, which can increase the risk of gestational diabetes. If drinking colas, remember to track the caffeine content toward your daily limit.
