Raw milk,
does it really help with Prevention of childhood asthma and allergic disease?
research showsThe grade is C with 56 points. In the European GABRIELA survey of 8,334 schoolchildren, parent-reported raw farm-milk consumption was associated with lower asthma odds after adjustment for other farm exposures, adjusted OR 0.59, 95% CI 0.46 to 0.74. In the prospective PASTURE cohort, among 934 children with milk data, unprocessed farm-milk consumption at age four was associated with asthma at age six, adjusted OR 0.26, 95% CI 0.10 to 0.67. Milk was not randomized, and parents reported both exposure and physician-diagnosed asthma, so prevention is not established.
ads claimMeasured protein, fat, and microbial differences between raw and heated milk are real composition facts. They do not prove that raw milk safely prevents asthma in children outside farm settings. Verdict 2060 is D with 28 points and concerns lactose-intolerance symptoms, a different endpoint.
Useful facts when choosing a product
- In 800 household samples, raw farm milk had more detectable viable bacteria and higher concentrations of some heat-sensitive whey proteins than heated farm or shop milk.
- Boiled farm milk was not associated with lower asthma odds, adjusted OR 1.11, 95% CI 0.86 to 1.44.
- PASTURE classified exposure by the usual milk type reported yearly, not by a measured gram dose.
- Verdict 2060 is D with 28 points and addresses lactose intolerance rather than asthma or allergy prevention.

What the research actually shows
GABRIELA surveyed parents of 8,334 schoolchildren in rural Germany, Austria, and Switzerland, measured specific IgE in 7,606, and analyzed household milk samples from 800 homes. Associations with asthma, atopy, and hay fever persisted after adjustment for other farm exposures, but the analysis was cross-sectional. PASTURE enrolled 1,133 rural children from birth and analyzed annual milk-consumption data in 934; parents reported physician-diagnosed asthma at age six. Because the studies differed in design and timing, they were not counted as direct replication of one estimate. European public funding was verified.
Why this is classified as C (56)
Large associations with human asthma events appeared in two European data sets, but nonrandom exposure, parent reporting, and residual farm-environment confounding limit the evidence to C with 56 points.
Counterpoint. The heated-milk comparison and prospective follow-up make the signal credible enough not to dismiss, but infection risk prevents raw milk from becoming a recommended preventive intervention.
Rejudgment record. Cross-check applied — The raw-versus-heated farm-milk comparison, adjustment for farm exposures, repeated PASTURE exposure assessment, age-six asthma outcome, and analysis counts were checked against the original reports
| Endpoint | H | Hard endpoint - actual events such as death |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
Stored derived and displayed grades match; this is not a current recalculation or validity check (C).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Raw milk consumption and lower childhood asthma | C | A cross-sectional survey and birth cohort found inverse associations without a causal trial. |
| Raw milk consumption and lower atopy or hay fever | C | Adjusted GABRIELA associations were positive but reporting and residual confounding remain. |
