Replacing Animal Fats With Vegetable Oils May Not be as Heart Smart as Originally Believed

A team of American and Australian researchers have found that advising patients with coronary heart disease to replace saturated fats with polyunsaturated fats may actually increase the risk of death from all causes, coronary heart disease, and cardiovascular disease. This new finding seems to fly in the face of dietary recommendations from many health organizations including the American Heart Association.

The linch pin in this surprising development is the discovery of the missing data from the Sydney Diet Heart Study, a randomized controlled clinical trial conducted from 1966 to 1973. When the research team performed an analysis of the information gathered from 458 male study participants aged 30-59 years who had recently had a coronary event, they used current statistical methods to compare death rates from all causes, cardiovascular, and coronary heart disease.

The study participants were broken down into two groups:

  • Intervention group – 221 participants who were instructed to replace saturated fats from animal fats, margarines, and shortenings with omega 6 linoleic acid from safflower oil and safflower oil polyunsaturated margarine
  • Control group – 237  participants who were not given and dietary instructions

Here’s what the researchers found:

  • The intervention group had a 17.6 percent risk of death from all causes, a 17.2 percent risk of death from cardiovascular disease, and a 16.3 percent risk of death from coronary heart disease.
  • The control group had an 11.8 percent risk of death from all causes, an 11 percent risk of death from cardiovascular disease, and a 10.1 percent risk of death from coronary heart disease.
