Trans Fats Update

I just updated the Trans Fats section of The Fatty Acids page on It’s nothing earth-shattering, but reflects the results of a review of the evidence regarding trans fats and heart disease. Here is the update:

A 2008 review of trans fats and cardiovascular health found:

* Five meta-analyses of controlled dietary interventions have examined the relationship between trans fatty acids intake and blood lipid levels and consistently report a worsening of blood lipid profiles with increasing trans fatty acid intakes, with a dose-response relationship evident.

* Four cohort studies report on the association between trans fatty acid intake and incidence of cardiovascular disease. They consistently found that larger amounts of trans fats (about 4 to 6 grams per day) increased heart disease rates by about 25% in comparison with the lowest amounts (about 1 to 2 grams per day).

* Vegetable based trans fats were found to be more harmful than animal-based (those found naturally in ruminent animal products).

    The most interesting point for me regarding the trans fat discussions has been that they shy away from an honest comparison to the risks of saturated fats? I believe that trans fats can be slightly worse than saturated fats – but only slightly.
