Are butter fats safer than margarine fats?
Effects of ruminant trans fatty acids on cardiovascular disease and cancer: a comprehensive review of epidemiological, clinical, and mechanistic studies.

Some studies suggest that trans fats from processed oils (like margarine) might hurt your heart, but trans fats from cows (like butter) might not. Scientists aren't sure yet because the studies on butter fats were small or used too much fat. No one has studied if either kind causes cancer in people.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Evidence Score
Based on clinical experience or non-systematic literature reviews. The lowest level of evidence as they are most susceptible to bias and personal perspective.

Industrial hydrogenation of vegetable oils generates trans fatty acids, which are causally linked to increased risk of cardiovascular disease and metabolic dysfunction.
Small experiments on ruminant trans fats and heart health markers haven't given clear answers — maybe because they used too few people or too much fat that you can't actually eat in real life.
We don’t know if natural trans fats from meat and dairy affect cancer risk — no solid human studies have looked at this yet.
Some studies suggest that the natural trans fats found in milk and meat might not raise heart disease risk the same way that artificial trans fats in fried and baked foods do.
