A new study found that olive oil improved the hearts of rats with heart failure. More research is needed, but the findings could have implications for humans as well.

The study, published in the journal Circulation, removed hearts from rats with heart failure to study the effects of fat on the hearts. The scientists kept the rat hearts beating, treating some of the hearts with oleate, a substance found in olive oil and canola oil, and some with palmitate, a substance found in palm oil, animal fat, and dairy products.
