New Look at Old Study Casts Doubt on Value of Vegetable Fats for Heart Health

A new analysis of data missing from a study that ended more than 40 years ago casts doubt on current dietary advice about vegetable fats and heart health.

The clinical trial published in the British Journal of Medicine shows that replacing saturated animal fats with omega-6 polyunsaturated vegetable fats (PUFAs) is linked to an increased risk of death among patients with heart disease.

Nutrition epidemiologist and study co-author, Daisy Zamora, PhD, is postdoctoral researcher in the Program on Integrative Medicine in the Department of Physical Medicine & Rehabilitation at the University of North Carolina School of Medicine.

She said, “These findings highlight the need to re-evaluate worldwide dietary advice to substitute omega 6 PUFAs for saturated fats.”
