The researchers compared HDL cholesterol in people who ate almonds nearly every day to those who ate a muffin daily. The researchers found that HDL cholesterol function was better in those who ate almonds than those who ate muffins.
Professor of nutrition, Penny Kris-Etherton, explained, “There’s a lot of research out there that shows a diet that includes almonds lowers low-density lipoprotein, or LDL cholesterol, which is a major risk factor for heart disease. But not as much was known about how almonds affect HDL cholesterol, which is considered good cholesterol and helps lower your risk of heart disease.”
The researchers not only wanted to determine if almonds could improve cholesterol levels but also if HDL function could improve too. Kris-Etherton added, “HDL is very small when it gets released into circulation. It’s like a garbage bag that slowly gets bigger and more spherical as it gathers cholesterol from cells and tissues before depositing them in the liver to be broken down.”
The study included 48 men and women who were put on controlled diets over the course of six weeks. The meals in both groups were near identical except for what they enjoyed for snacks—either almonds or a muffin.
At the end of the six weeks, the researchers measured levels and functionality of HDL cholesterol. These results were then compared to the baseline findings.
The almond diet was found to improve cholesterol levels along with functionality compared to those who ate a muffin as a snack.
Kris-Etherton concluded, “We were able to show that there were larger particles in response to consuming the almonds compared to not consuming almonds. That would translate into the smaller particles doing what they’re supposed to be doing. They’re going to tissues and pulling out cholesterol, getting bigger, and taking that cholesterol to the liver for removal from the body.”
Increasing subpopulations of HDL cholesterol is beneficial because it has been found to further reduce the overall risk of cardiovascular disease.
Although almonds are beneficial to heart health, it’s important you eat them in moderation because they are high in fat and calories. Stick to about a handful a day for optimal benefits.
