Is vegetable oil good for you?
Despite some health benefits, many doctors long have warned that vegetable oils - such as soy, corn and canola oils - are a source of calories and that Americans may be consuming too much of them. However, new research from the University of Missouri and the University of Illinois confirms the beneficial properties of vegetable oils, specifically that the linoleic acid in the oil is associated with lower risk of heart disease. The research, the scientists said, showed no link between vegetable oil consumption and circulation inflammation, which is associated with heart disease, cancer, asthma and arthritis.
In a study of more than 500 adults, the researchers investigated the health properties of vegetable oil and, more specifically, linoleic acid. Earlier research with animals had suggested a link between linoleic acid and inflammation that can lead to chronic diseases. But this study did not find such a connection with humans.
Linoleic acid is an essential nutrient and an omega-6 fatty acid, which has supports heart health. Americans, on average, consume about three tablespoons of vegetable oil a day, in line with the American Heart Association and Institute of Medicine recommendations.
