Adding one avocado to the daily diet may reduce heart disease risk in adults living with obesity, according to research led by the Penn State University Department of Nutritional Sciences and published in the Journal of Clinical Lipidology.
The team found that regular consumption was associated with a lower concentration of low-density lipoprotein (LDL) particles – the protein particles that transport cholesterol around the body – in the blood.
That reduction corresponded to an approximate 4% decrease in risk.
What distinguishes the finding is its modesty.
Rather than testing a wholesale dietary overhaul, the researchers examined what happens when people make one addition and otherwise carry on as normal.
A Penn State study found adults living with obesity who ate one avocado daily cut LDL particle levels by 49 nmol/L – around a 4% lower heart disease risk. (154 characters)
