According to Hernández-Díaz et al., a small 2014 pilot found spicy-food intake associated with spontaneous preterm labor or membrane rupture within 24 hours in a selected group. The study did not test typical meal amounts or report a trimester-specific effect. Its case-crossover design cannot show that spicy food caused the events, and the authors discuss recall and early-symptom bias. The NHS says reducing spicy foods can ease pregnancy indigestion and heartburn. Ask your provider about your situation.

Chaudhry et al. surveyed 201 postpartum women; 10.9% reported eating spicy food while trying to start labor, but the survey did not test whether it worked. The NHS says there is no evidence that home methods start labor or that certain foods or drinks trigger it. That guidance addresses home labor induction and does not settle the separate 2014 pilot signal for preterm labor or membrane rupture. NHS guidance also says reducing spicy foods can ease pregnancy indigestion and heartburn. Ask your provider about your situation.

Spicy Food — Breastfeeding
Research strength: 2 / 5
According to LactMed, two breastfed infants developed temporary dermatitis after their mothers ate red-pepper-spiced food; Cooper and Cooper reported the same two cases. LactMed says maternal milk and infant blood levels were not available, so these reports cannot show how common a reaction may be. The report does not establish a general restriction for all spicy foods. LactMed separately cautions against topical capsaicin cream on the breast or places an infant can touch, which is a different exposure. Ask your provider about your situation.

Pregnancy
Hernández-Díaz et al. (2014) conducted a pilot case-crossover study with 50 women with spontaneous preterm labor, 50 with preterm premature rupture of membranes (PPROM), and 158 matched controls. Among the case participants, reported spicy-food intake in the prior 24 hours was associated with PTL/PPROM (OR 7.0, 95% CI 1.6 to 30.8). This was a selected case group, the exposure was self-reported, and the paper did not report a standard serving or establish a trimester-specific effect. The authors discuss possible reverse causation from early symptoms and recall bias, and state that larger studies are needed. Chaudhry et al. (2011) surveyed 201 postpartum women; 10.9% reported trying spicy food to induce labor. The survey recorded attempts, not whether the food worked. A 2026 quasi-experimental study of 60 primigravidae at 28 to 36 weeks reported an association between spicy-food intake and heartburn severity in the class group. That study did not test spicy food as an intervention or measure labor outcomes. The NHS independently says reducing rich, spicy, or fatty foods can ease pregnancy indigestion and heartburn.
Breastfeeding
Cooper and Cooper (1996) reported transient red dermatitis in two breastfed infants after their mothers ate food flavored with red pepper. LactMed describes the cases as probably related to maternal red-pepper intake. LactMed reports that relevant maternal milk and infant blood levels were not found as of its 2021 revision, so the reports do not estimate how often a reaction occurs. They do not establish a general restriction for all spicy food. LactMed's caution about topical capsaicin cream concerns skin contact with the infant, not ordinary food intake.
Cayenne peppers (Capsicum species) contain capsaicin and related compounds that give them a hot, spicy flavor, according to LactMed. This entry covers ordinary culinary food, not concentrated capsaicin supplements or topical capsaicin products.
What was tested
The 2014 pilot interviewed women about exposures in the 72 hours before spontaneous preterm labor or PPROM and compared the 0 to 24 hour window with the 48 to 72 hour window; it did not randomize food or standardize a serving. The 2011 postpartum survey asked what methods women had tried to induce labor, not whether the methods were effective. The 2026 study tested an antenatal class, while spicy-food intake was an associated factor for heartburn severity rather than an assigned exposure. The 1996 breastfeeding report described two infants after maternal red-pepper meals; no milk or infant blood concentration data were available in LactMed.
Does spicy food start labor or relate to preterm labor?
- Source A says
- The NHS says there is no evidence that home methods start labor or that certain foods or drinks trigger it. (NHS: Inducing labour)
- Source B says
- Hernández-Díaz et al. reported an association between spicy-food intake and spontaneous preterm labor or PPROM within 24 hours in a small pilot case-crossover study. (Hernández-Díaz et al., 2014: Triggers of spontaneous preterm delivery)
- Why they differ
- The NHS statement concerns home methods intended to start labor, usually at term. The pilot measured a short-term association before preterm labor or PPROM in a selected case group. Its authors discuss early symptoms and recall as possible sources of bias, so the findings are not a direct test of term induction or ordinary meal amounts.
- What the evidence shows overall
- The evidence does not establish that spicy food induces labor at term or that ordinary portions cause preterm labor. One small pilot reported a short-term association in selected cases, but it cannot establish cause or the risk for typical meals.
- The NHS says cutting down on foods that are rich, spicy, or fatty can ease indigestion and heartburn symptoms during pregnancy. (NHS)
- The NHS says there is no evidence that home methods start labor or that certain foods or drinks trigger labor. (NHS)
- LactMed cautions against applying capsaicin cream to the breast or other parts of the body that an infant may contact; this is a topical exposure, not ordinary food intake. (LactMed)
