A review published on March 27, 2026, in Nutrition Research analyzed 22 controlled trials and observational studies involving thousands of participants across Europe, Canada, and the United States. The findings indicated no association between naturally occurring trans fats found in dairy products and an increased risk of heart disease or type 2 diabetes.
Why it matters
Researchers sought to clarify the nutritional distinctions between natural dairy trans fats and industrial trans fats, which are created through the partial hydrogenation of vegetable oils. Distinguishing these sources is essential for understanding how specific dietary components influence chronic disease risk.
The meta-analysis included 10 controlled dietary trials and 12 cohort studies, with some participants followed for over two decades. Researchers evaluated daily trans fat intakes ranging from 1.3 to 13.2 grams and observed no meaningful differences in blood lipid profiles.
The players
Nutrition Research
This is a peer-reviewed academic journal that publishes scientific findings related to human nutrition and dietary health.
The details
The study compared participants with enhanced dairy intake against those with regular dairy consumption to assess biomarker levels in the blood. Unlike industrial trans fats, which are well-documented health hazards, the naturally occurring versions found in milk, butter, yogurt, and cheese showed no negative health correlations.

The Big Picture
This study refines the nuance of the FDA 2015 ban on partially hydrogenated oils by demonstrating that not all trans fats carry the same cardiovascular risk profile.
This research suggests that dairy consumers do not need to avoid natural trans fats due to cardiovascular concerns. Readers can continue their existing dietary habits involving milk, yogurt, and cheese without the fear of increased heart disease or diabetes risk linked to these fats.
The takeaway
Distinguishing between natural and industrial fats is critical for building a heart-healthy diet. Readers should prioritize limiting processed, hydrogenated oils while feeling confident in the safety of natural dairy-derived fats.
