A study conducted by University of Pennsylvania researchers said that eating one avocado a day can reduce levels of bad cholesterol. LDL cholesterol (low-density lipoprotein) that can accumulate in the walls of blood vessels can cause a stroke or heart attack.
In a study published in the journal Nutrition, the researchers recruited 45 adults who are obese. During the first two weeks, the study participants ate the same foods, imitating the average diet of Americans, allowing all participants to depart on the same nutritional footing.
The participants were then randomly separated into three groups. Each group followed a low-fat diet, a moderate-fat diet, as well as a moderate-fat diet plus eating avocados every day.
Five weeks later, participants who ate avocados every day had oxidized LDL cholesterol levels that were significantly lower than before. In addition, after the diet coupled with eating avocados, participants also had higher levels of lutein and antioxidants.
In other words, research shows that avocados can reduce oxidized LDL, where oxidation can negatively impact the human body.
“All LDLs are bad; Dense LDL is very bad. An important finding is that people who are on an avocado diet have fewer oxidized LDL particles. They also have more lutein, which bioactively protects LDL from oxidation,” said leading nutrition professor, Penny Kris Etherton in a statement reported by Fox News on Wednesday (30/10).
“We know that when LDL particles are oxidized it can start chain reactions. which can trigger atherosclerosis which is a buildup of plaque on the artery walls. Oxidation is not good, so if you can protect the body with the food you eat, it can be very beneficial,” explained Etherton.
However, Etherton did not provide notes that further research is needed to find out the health benefits of avocados. So far, avocados are known to be full of essential nutrients, such as vitamin K, potassium, to antioxidants.
“Avocados are nutrient-dense packages and I think we are just learning about how avocados can improve health,” he said.
