Looking at more than 1,000 overweight or obese participants, the researchers conducted a six-month experiment.
Half of these subjects were told to eat avocado daily while the others followed their usual diet and limited consumption of the fruit.
The research team found that avocados were able to lower total cholesterol by 2.9 milligrams per decilitre (mg/dL) and LDL cholesterol by 2.5 mg/dL.
Now, the researchers plan to continue analysing the data, possibly pinning down an effective way to include avocados in a diet.
