Is orange juice good during pregnancy?

Pasteurized orange juice in ordinary amounts looks neutral in pregnancy, and the one firm rule is about juice that was never pasteurized. We found no randomized trial of orange juice on any pregnancy outcome. For gestational diabetes, a 2023 meta-analysis of 4 prospective cohorts with 23,177 women, 1,598 of whom developed it, found no link with fruit juice intake (RR 0.97, 95% CI 0.91 to 1.04). These cohorts measured fruit juice in general, not orange juice alone.

Unsettled. The answer stays open because single cohorts point in opposite directions and none of them can show cause. A Chinese study of 2,987 women linked more fruit juice in weeks 13 to 28 to more gestational diabetes. A Malaysian cohort of 452 women linked more juice before pregnancy and in the first trimester to less. The pooled cohorts and a 2025 systematic review of 3 studies both came out neutral.

Fruit juice in pregnancy, on a risk scale

Observational data

All four rows are observational and cannot show cause. The first two are risk ratios from a meta-analysis, the last two are odds ratios from single cohorts, and none of the studies report absolute risks for juice drinkers in what we read. Sources: cards ev-ojp-02, ev-ojp-11 and ev-ojp-08 below.

What the trials found

The only trial evidence that touches orange juice in pregnancy is about fetal heart checks. A Cochrane review of 2 randomized trials with 708 pregnant women tested giving the mother sugar before antenatal cardiotocography. According to the review's description, one of the trials used reconstituted orange juice with 20 g of carbohydrate. Maternal glucose did not decrease the number of non-reactive tests.

A later randomized trial of 360 pregnant women having a non-stress test reached a different result. Women given cake and juice 30 minutes before the test had more fetal movements and more accelerations than women given nothing (p below 0.001). There was no placebo and no blinding, and the abstract names neither the juice nor the amount of carbohydrate.

Unsettled. Whether a glass of juice before a fetal heart check changes the result is a real disagreement. The Cochrane pool of 2 trials found no effect on non-reactive tests. One unblinded trial of 360 women found more movement with cake and juice, measured against doing nothing at all.

Another trial tested whether juice reaches the blood. In 190 pregnant women at an antenatal clinic in a deprived area, vouchers exchangeable for fruit juice raised juice intake. Serum beta-carotene rose from 106.2 to 141.8 in the voucher group (P = 0.003) and fell from 120.0 to 99.8 in controls (P = 0.005). The abstract labels these values micromol per liter, a unit we could not check against the full text, so we read them only as a direction of change. That is a blood marker. The trial did not report any pregnancy outcome, and the abstract does not say which juice.

What the cohorts say about the children

Studies that followed children born to juice-drinking mothers mostly found nothing. In the US Project Viva cohort of 1,234 mother-child pairs, juice in pregnancy was not associated with the child's cognition scores. In a Spanish cohort of 252 mother-child pairs, total and natural fruit juice showed no association with overweight at age 4. Commercial fruit juice was associated with higher odds of it (OR 2.48, 95% CI 1.06 to 5.78), and the authors call the finding exploratory.

A Finnish birth cohort of 2,441 children linked high maternal intake of fruit and berry juices in pregnancy to allergic rhinitis by age 5 (adjusted OR 1.40, 95% CI 1.03 to 1.90), with no link to asthma. It is one cohort that tested many foods, and the juices were not only orange.

Who should be careful

Not for everyone. Pregnant women should avoid untreated, unpasteurized juice. The FDA warns that children, older adults, pregnant women and people with weakened immune systems risk serious illness or even death from drinking untreated juices. The agency gives no infection rates. Most juice sold in the United States is pasteurized to kill harmful bacteria. The warning is about juice that has not been treated.

On birth defects, one large cohort found no signal for juice. In a Norwegian study of 88,514 pregnancies, fruit juices showed no association with congenital heart defects. It is observational, and a single study.

What expert bodies say

The only expert statement in our material is the FDA's, and it is about pasteurization. We did not find a position from a public health or obstetric body on how much orange juice to drink in pregnancy.

How we searched

Searched: a local copy of PubMed for orange, citrus, fruit and 100% juice with pregnancy, gestational, maternal, prenatal and offspring terms (90 records, most about juice given to children). Narrower searches crossed juice with gestational diabetes, birth weight, preterm birth, asthma and cognition (27 records), and with meta-analyses on gestational diabetes (1 record). We also searched the web, Europe PMC, the FDA site, ClinicalTrials.gov and Retraction Watch, on 7 October 2026.

Included: one Cochrane review, two randomized trials, one meta-analysis and one systematic review of cohorts, six single cohorts and one FDA consumer page.

Excluded: a Project Viva analysis of asthma whose abstract does not separate juice, a maternal diet score where juice could not be separated, studies of juice given to children rather than drunk in pregnancy, and orange juice trials in adults who were not pregnant.

What we read: the full text of the 2023 meta-analysis, abstracts for everything else, and the FDA page itself.

What we could not get: the full text of the Cochrane review and of the 2025 systematic review, so the pooled numbers behind the word neutral are missing. We also could not find the original orange juice trial cited inside the Cochrane review, or the text of the US labeling rule for unpasteurized juice.

What would change this answer

A randomized trial of 100% orange juice against whole fruit or water in pregnancy, measuring blood sugar and birth outcomes. None was registered on ClinicalTrials.gov when we checked.
A larger, blinded trial of juice before fetal heart testing, which would settle the disagreement between the Cochrane review and the cake and juice trial.
A cohort that repeats the Spanish finding on commercial juice and child weight with more than 252 families. One exploratory result is a reason to look again. On its own it says little about what to drink.
