Eggs have always been a hot topic in the world of nutrition.
Some experts say they’re bad for your heart and cholesterol, while others say they’re packed with nutrients.
Now, a new study offers fresh insight—especially for healthy young adults.
Most past studies looked at people who already had health problems or were at risk for conditions like heart disease or diabetes.
But those results don’t always tell us how eggs affect healthy people. That’s why researcher Catherine J. Andersen and her team wanted to take a broader look.
In this study, participants were divided into three groups. One group didn’t eat eggs, another ate three egg whites a day, and the last group ate three whole eggs a day. They were allowed to cook the eggs any way they liked. The researchers checked several health markers, including cholesterol, blood sugar, and inflammation levels.
Here’s what they found:
People who ate whole eggs had more choline in their bodies. Choline is a key nutrient found in egg yolks and helps with brain and cell health. Normally, higher choline might raise something called TMAO, which is linked to heart problems. But in this study, TMAO levels stayed the same, even with more choline.
There were no harmful changes in cholesterol or inflammation levels for people who ate whole eggs. In fact, those who ate whole eggs had better blood sugar markers compared to those who ate just egg whites.
People in the whole egg group also had more nutrient-dense diets and higher red blood cell counts (measured by hematocrit), both signs of good health.
There were some differences based on gender. Some women in the study were taking birth control pills, and others were not. Women not on the pill saw a bigger rise in the total-to-HDL cholesterol ratio, which can be a heart risk. They also had more monocytes, a type of immune cell. These immune changes were linked to changes in “good” cholesterol (HDL) markers.
This study is just the beginning. Andersen’s team plans to dig deeper into how eggs affect the immune system and “good” cholesterol. They also want to study how age, gender, genes, and gut bacteria play a role.
So, what’s the takeaway? For healthy young adults, eating whole eggs doesn’t seem to hurt and might even help. As always, more research is needed, but this study points to a future where nutrition advice can be more personal and tailored to your body.
