New Eggs and Diabetes Link? You May Be Surprised

New studies have shown a new relationship between the consumption of eggs and Diabetes.

Previously, studies have shown that eating eggs is not harmful to those with Pre-Diabetes and Diabetes, in terms of heart disease risk.

However, these newer ones were different.

They set out to establish if there was a link between eating eggs before diagnosis, and the risk of developing Type 2 Diabetes. In addition, the investigators wanted to determine why and how eggs affected the risk.

When it comes to eggs, it seems there are constantly differing views and even contraindicating studies.

Would this most recent study fly in the face of the last one? Does eating eggs have any implication on your risk of developing Type 2 Diabetes and Pre-Diabetes?

Here are the details of the latest studies and what the researchers found to be a link between eggs and Diabetes.

The Latest Eggs and Diabetes Studies

Researchers at the University of Eastern Finland studied 239 men to determine if egg consumption increased the risk of developing Type 2 Diabetes (1). They divided the men into groups based on their egg intake, and their development of Diabetes (or not).

What they found was that consumption of about one egg per day on average correlated with the lowest risk of developing Diabetes. This was the “high egg intake” group.

The next study aimed to figure out why.

What was it about the eggs that could reduce the risk of Diabetes?

They found a link.

The blood plasma samples of the “high egg group” contained a metabolite that’s associated with those with a lower risk of Diabetes. They also found a few compounds in blood samples that were positively associated with developing Type 2 Diabetes.

Although they could not establish a cause-effect relationship, they felt further investigation between this egg and diabetes link is warranted, and identifying protective metabolites is helpful.

Previous Eggs and Diabetes Studies

Previously, studies have shown that egg consumption does not increase the risk of heart disease in those with Diabetes and Pre-Diabetes. One study followed subjects for 12 months, in 3 different phases. They included:

  • For the first three months, the subjects either high-egg diet (including 12 eggs per week) or a low-egg diet (including two eggs per week). During this time, no difference in cardiovascular risk was found. The subjects also aimed to maintain their current weight.
  • For three more months, the subjects maintained the same egg consumption while following a weight loss diet.
  • For six additional months, the subjects continued the same egg consumption and were followed up by researchers. This added up to 12 months in total.

At the end of the study, the researchers found that there were no adverse changes in cardiovascular risk markers regarding eggs and diabetes, both in the high- and low-egg groups.

Benefits of Eggs

In recent years, more and more doctors and experts have been leaning towards eggs-as-healthy.

In fact, many have cited a 2012 study in the journal Current Opinion in Clinical Nutrition and Metabolic Care found that people who ate moderate amounts of eggs did not show increases in cholesterol when compared to those who cut eggs out of their diets completely (2).

Other studies have found that antioxidants in eggs reduced the risk of cardiovascular disease and cancer. They may even help lower blood pressure (3).

Moreover, eggs can promote:

  • Improved HDL cholesterol levels, by up to a 10% increase with 2 eggs per day (45)
  • Adequate choline, lutein, and zeaxanthin intake. Choline builds cell membranes and plays a role in brain function and memory (6). Lutein and zeaxanthin are powerful antioxidants that promote eye health in the retina (7).
  • Improved triglycerides by as much as 16-18% decrease when eating pasture-raised high omega-3 eggs (8).
  • Good protein intake which can improve satiety and weight loss especially compared to eating carbohydrates.

While egg used to be looked at as little more than protein mixed with cholesterol, we now know their nutrients and metabolites are important to human health.

These new study may contribute to the conclusion of more benefits: Eggs may reduce the risk of Diabetes.

Bottom Line

Eggs have a lot to offer nutritionally, and another study has been added to show their benefits. When it comes to an eggs and diabetes link, these new studies build off of previous ones. Not only do eggs not increase heart disease, but they are also now implicated in lowering the risk of Diabetes.

    Oh, dear, Dr. Colbert. Don’t scare me like that! Eggs are a staple of my diet. I was so glad to read the bottom line because I love eggs! They really help to keep my weight in check. The incredible, edible egg! 😉

  2. Fertilized chicken eggs have higher lecithin and lower cholesterol than un
    Fertilized eggs! (Dictionary of nutrition )
    One of my customer was a heart patient, whose Doctor would not allow any grocery eggs (unfertilized)
    But on the farm with a rooster, the hen eggs were good to be eaten.

  3. That’s good to know I eat usually 2 eggs a day

    Thank You for all of your effort to study and to keep us informed

    I found this very interesting as I am not eating a lot of eggs right now. So, I should increase my intake and see if my blood pressure does better! Thank You!

      You can certainly add some eggs and monitor your results. They are a healthy protein source for most people. Thank you!
