Is Soda Safe During Pregnancy? (Updated 2026 Guide)
Updated April 13, 2026
The Answer
Soda can be an occasional pregnancy choice, but formulations vary widely. Of the 2,809 sodas we reviewed, only 318 received an A grade, while most received grades from C through D.
The main considerations are caffeine, added sweeteners, preservatives, artificial colors, and artificial sweeteners. Caffeine intake above 200 mg daily is linked to increased miscarriage risk and low birth weight, while several other common soda ingredients carry caution ratings based largely on animal studies or limited human evidence.
Pregnancy Safe is 100% independent and research driven. No companies pay to promote or sponsor products.

✓ What's Safe
- • Caffeine free options, especially if you also consume coffee, tea, chocolate, or other caffeine sources
- • Unsweetened or lower sugar formulations without high fructose corn syrup
- • Short, straightforward ingredient lists with fewer preservatives, dyes, and artificial sweeteners
- • Plain or lightly flavored sparkling water when you mainly want carbonation
- • Clearly labeled serving sizes so you can track caffeine and sweetener intake across the day
✗ What to Avoid
- • Frequent or large servings of soda containing high fructose corn syrup
- • Sodas that push your total daily caffeine intake above 200 mg
- • Formulas containing aspartame when a simpler alternative is available
- • Brightly colored sodas containing red 40, yellow 5, or blue 1
- • Products containing sodium benzoate or potassium benzoate, particularly when you can choose a preservative free option

Ingredients to Watch Out For in Soda
These are the most common flagged ingredients across 2,809 soda products we analyzed.
high fructose corn syrup
CAUTION
High fructose corn syrup is a sweetener derived from corn starch and widely used in processed foods and beverages. Has been associated with placental insufficiency, fetal growth restriction, and metabolic programming of offspring in animal studies, and with gestational diabetes and preeclampsia in epidemiological studies of humans.
Found in 1584 of 2,809 products (56%)
sodium benzoate
CAUTION
Sodium benzoate is a food preservative in beverages and processed foods. Has shown birth defects in animal studies at high doses and may form benzene when combined with vitamin C.
Found in 1067 of 2,809 products (38%)
caffeine
CAUTION
Caffeine is a stimulant found in coffee and tea. Is linked to increased miscarriage risk and low birth weight above 200 mg daily.
Found in 885 of 2,809 products (32%)
red 40
CAUTION
Red 40 is a synthetic red food coloring. May affect neurobehavioral development based on animal studies at high doses.
Found in 779 of 2,809 products (28%)
potassium benzoate
CAUTION
Potassium benzoate is a food preservative in beverages and processed foods. Has shown birth defects in animal studies at high doses and may form benzene when combined with vitamin C.
Found in 773 of 2,809 products (28%)
yellow 5
CAUTION
Yellow 5 is a synthetic yellow food coloring. Has shown embryotoxic effects in recent animal studies at high doses.
Found in 364 of 2,809 products (13%)
blue 1
CAUTION
Blue 1 is a synthetic blue food coloring. Has limited human pregnancy data with possible neurobehavioral effects in animal studies.
Found in 361 of 2,809 products (13%)
aspartame
CAUTION
Aspartame is an artificial sweetener commonly found in diet sodas, sugar free foods, and tabletop sweeteners. Has been linked in animal studies to placental dysfunction, reduced birth weight, and oxidative stress, with limited human data suggesting possible developmental concerns.
Found in 338 of 2,809 products (12%)

Your Questions Answered
Can I drink soda during pregnancy?
An occasional soda may fit into your diet, but the ingredients and serving size matter. Check for caffeine, high fructose corn syrup, artificial sweeteners, preservatives, and synthetic dyes. Because only 318 of the 2,809 sodas we reviewed earned an A grade, do not assume every soda is equally suitable.
How much caffeine from soda is too much during pregnancy?
Caffeine is linked to increased miscarriage risk and low birth weight above 200 mg daily. Count caffeine from soda together with coffee, tea, chocolate, and other sources. A caffeine free label can simplify your choice, but you should still review the remaining ingredients.
Is sugar free or diet soda a better choice during pregnancy?
Sugar free soda removes or reduces sugar, but it may replace it with artificial sweeteners such as aspartame. Aspartame carries a caution rating because animal studies suggest possible placental, birth weight, and oxidative stress concerns, while human developmental data remain limited. Compare the full ingredient list rather than relying on a “diet” or “zero sugar” claim.
Is caffeine free soda automatically a safer option?
Not necessarily. Caffeine free soda may still contain high fructose corn syrup, benzoate preservatives, artificial colors, or aspartame. Treat caffeine free labeling as one useful feature, not a complete safety assessment.
Is ginger ale safe during pregnancy?
Evaluate ginger ale like any other soda rather than assuming its flavor makes it beneficial. Check whether it contains caffeine, high fructose corn syrup, benzoate preservatives, artificial sweeteners, or synthetic dyes. The product’s complete formulation and your serving frequency matter more than the words “ginger ale.”
What can I drink instead of soda during pregnancy?
Plain water or unsweetened sparkling water can provide hydration, while sparkling water also supplies carbonation without the typical soda additives. Lightly flavored carbonated water may work if its ingredient list is simple. Check labels because products marketed as sparkling beverages can still contain caffeine, sweeteners, preservatives, or dyes.
How Do We Score Products for Pregnancy Safety?
We analyze each product's ingredients and category to flag known risks and provide cautionary notices for general category safety concerns.
A - Safe
Excellent choice! All ingredients are considered safe during pregnancy.
What to do: Use with confidence.
B - Likely Safe
Pretty much safe with very minimal risk. Some ingredients may have limited pregnancy studies, but no significant safety concerns have been identified.
What to do: Use with confidence.
C - Limit
Contains ingredients with some pregnancy considerations. Research shows these ingredients may have limited safety data, potential for minor hormonal effects, or require caution based on animal studies.
What to do: Use sparingly and consider safer alternatives when available.
D - Caution
Similar to C grade but contains multiple cautionary ingredients. The combination increases overall concern.
What to do: Try to avoid if that makes you feel better. If you've already used it, no need to panic.
F - Avoid
Contains ingredients with established risks during pregnancy. Research shows these can cause birth defects, developmental harm, or serious maternal complications.
What to do: Do not use during pregnancy. If you've already used it, don't worry - contact your OBGYN if concerned.
