The risk of heart disease and diabetes may be lowered by a diet higher in a lipid found in grapeseed and other oils, but not olive oil, a recent study suggests.
Researchers at The Ohio State University found that men and women with higher linoleic acid levels tended to have less heart- threatening fat nestled between their vital organs, more lean body mass and less inflammation. And higher linoleic acid levels also meant a lower likelihood of insulin resistance, a precursor to diabetes.
This finding could have obvious implications in preventing heart disease and diabetes, but also could be important for older adults because higher lean body mass can contribute to a longer life with more independence, said Ohio State’s Martha Belury, a professor of human nutrition who led the research.
But there’s a catch. Low-cost cooking oils rich in linoleic acid have been disappearing from grocery shelves, fueled by industry’s push for plants that have been modified to produce oils higher in oleic acid.
