What the research found
Study (review of trials and cohorts). Constance Gayet-Boyer, D. Ian Givens, and colleagues report in Nutrition Research (2026; 150:33; DOI 10.1016/j.nutres.2026.03.009). They separated trans fats that occur in milk, butter, yogurt, and cheese from industrial trans fats made by partial hydrogenation. Ten feeding trials, with dairy trans fat intakes of about 1.3 to 13.2 grams a day, found no meaningful blood-lipid difference versus ordinary dairy. Twelve cohort studies, some longer than 20 years, in Europe, Canada, and the United States, did not link higher blood levels of dairy trans fats to heart disease, stroke, cardiovascular death, or type 2 diabetes. The paper does not say industrial trans fats are safe, and it does not claim dairy prevents disease. Not medical advice.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
