We've all heard the old saying, "One apple a day keeps the doctor away." However, according to a new study, the same may be the case with avocados – at least when it comes to lowering "bad" cholesterol levels.
A study conducted by researchers at Penn State University and published in the Journal of Nutrition suggests that consuming an avocado per day may lower levels of low-density lipoprotein (LDL), a type of cholesterol considered "bad." "High LDL levels can build up in the walls of blood vessels, sometimes causing a stroke or heart attack, at the Mayo Clinic.

Incl. on the other hand, high density lipoprotein or HDL is often considered to be "good" cholesterol.
For the study, researchers recruited 45 adults who were either overweight or obese. For the first two weeks, participants ate a diet that "mimicked the average American diet," which allowed everyone involved to "start a study on a similar diet," according to a news release.
The participants were later divided into random groups into three groups. Each group either followed a low fat diet, a moderate fat diet, or a moderate fat diet that also included eating avocados every day.
Five weeks later, those who ate avocados daily had "significantly lower levels of oxidized LDL cholesterol than before the study began or after the low and moderate diets were completed. fat "news release. "Participants also had higher levels of lutein, an antioxidant, after the avocado diet."
In other words, researchers have determined that avocados may be able to reduce oxidized LDL particles. Oxidation can adversely affect the human body.
"When you think of bad cholesterol, it comes packed in LDL particles that vary in size. All LDLs are bad, but small, solid LDLs are particularly bad. The key finding was that people on the avocado diet had less oxidized LDL particles. They also had more lutein, which may be bioactive, which protects LDL from oxidation, "said nutrition professor Penny Chris-Etherton in a statement.
"Many studies indicate that oxidation is at the heart of conditions such as cancer and heart disease," added Chris-Etherton. " We know that when LDL particles oxidize, it starts a chain reaction that can promote atherosclerosis, which is an accumulation. of the plaque in the wall of the artery. Oxidation is not good, so if you can help protect the body through the foods you eat, it could be very helpful. "

"They are such a nutrient dense package and I think it is only now we are starting to learn about how they can improve health, "she added.
