An avocado a day may lower "bad" cholesterol
A new study published in the Journal of the American Heart Association suggests that consuming one avocado a day as part of a moderate-fat diet could help lower bad cholesterol in people who are overweight or obese.
For their study, the researchers recruited 45 healthy participants aged 21 to 70 who were either obese or overweight. Every participant was required to follow each of three cholesterol-lowering diets for five weeks. The diets consisted of a low-fat diet without avocado, a moderate-fat diet without avocado or a moderate-fat diet with one Hass avocado a day.
At the conclusion of the study, the researchers found that participants’ levels of low-density lipoprotein (LDL) were an average of 8.3 milligrams per deciliter (mg/dL) lower after following the lower-fat diet without an avocado and 7.4 mg/dL lower after following the moderate-fat diet without an avocado, compared with their baseline average. However, after participants followed the moderate-fat diet with one avocado a day, their LDL levels were found to be an average of 13.5 mg/dL lower than their baseline average. Other blood measurements also improved – including triglyceride levels, total cholesterol, and small dense LDL.
The research team did acknowledge that this was a controlled feeding study, as opposed to a real-world situation, but encouraged people to consider replacing saturated fatty acids in their diet with healthier fats from avocados and other sources.
