Eggs Are Good Before and After Getting Diabetes

People with diabetes can benefit from eating two eggs a day without worsening cholesterol levels. And if you have pre-diabetes, eating eggs can help you avoid getting the disease.

Two new studies in a professional journal separately came to these conclusions. The American Journal of Clinical Nutrition, one of the world’s leading nutrition and dietetics medical journals, published them this month. The pre-diabetes study, published online on April 1 ahead of print at “Egg consumption and risk of incident type 2 diabetes in men,” comes from researchers in Finland. The diabetes study, published in the April issue of the journal at “The effect of a high-egg diet on cardiovascular risk factors in people with type 2 diabetes,” comes from researchers in Australia.

Eggs are healthful

For years, eggs have had a bad rap because egg yolks are the highest in cholesterol of any food. But the medical profession has generally come around to the conclusion reached by Berkeley Wellness that dietary cholesterol has relatively little effect on blood cholesterol in most people and that recent research has largely exonerated eggs, suggesting that they provide heart benefits.

Whole eggs are in fact one of nature’s most nutritious foods. A medium egg has almost 6 grams of protein, less than 1 gram of carbohydrate, and about 4 grams of fat, most of which is monounsaturated or polyunsaturated, according to the USDA’s National Nutrient Database. The protein in eggs is complete, with all of the essential amino acids in the proper proportions, according to NutritionData.

Pre-diabetes study results

“Eggs and especially egg yolks are a rich source of many nutrients that could have a beneficial impact on health,” according to the full-text of the new study that shows eggs can reduce the risk of getting pre-diabetes. While only the abstract of this study is free online, Jyrki Virtanen, a certified clinical nutritionist and an adjunct professor of nutritional epidemiology at the University of Eastern Finland, kindly sent me the full-text. “In addition to high-quality protein, PUFAs, vitamins, and minerals, these nutrients include several bioactive compounds that have been found to have anti-inflammatory properties.”

Professor Virtanen and his colleagues studied the eating and lifestyle habits of 2,682 men who took part in the Kuopio Ischaemic Heart Disease Risk Factor Study between 1984 and 1989. Two decades later, 432 of them had type 2 diabetes. The study found that eating more eggs was associated with a lower risk of type 2 diabetes as well as with lower blood glucose levels. Those who ate about four eggs a week had a 37 per cent lower risk of type 2 diabetes than the men who ate only about one egg a week.

Diabetes study results

The Australian egg study is a randomized, controlled trial of 140 people who either ate two eggs a day or two eggs a week. After three month, the study found no difference between the groups in total cholesterol, low-density lipoprotein cholesterol (the so-called bad cholesterol), triglycerides, or glycemic control. The study concluded that “a high-egg diet can be included safely as part of the dietary management of type 2 diabetes, and it may provide greater satiety.”

    Great! I would be interested in what you think about. I believe it is very recent.

      Thanks for your message, Kathy. This is actually not a recent article, but came out 5 years ago. It is not even a study. It is the outdated opinion of some people. In the meantime, even the mainstream medical establishment has stopped worrying about cholesterol, which is what the article is based on.

    I have a lot of respect for you. I thought you might have interest in these.

      Thank you for your comment, Kathy. I appreciate it and am sure that you realize that studies over the years have shown everything to be both good and bad. I report on what I think are the best ones.

    Interesting article; I personally talked to people who eat eggs almost every morning and have low cholesterol and wondered how that could be possible.
