In fact, more recent evidence suggests that "an egg a day" may keep the doctor away about as reliable as the proverbial "apple" of which Alex taught you that it'll keep the doc away.
In contrast to average Joes and Janes, though, individuals with type II diabetes (T2DM) whose metabolic state is characterized by impaired glucose metabolism, atherogenic dyslipidemia, and chronic low-grade inflammation, could be at a disadvantage of which some scientists still speculate that it was not compatible with a high(er) cholesterol diet.
To test whether that's correct and diabetics should better stay away from eggs, researchers from the Centro de Investigacion y Desarrollo in Mexico compared two breakfasts with perceived differences in effects on heart disease risk, eggs and oatmeal, by conducting a randomized, crossover clinical trial in subjects with T2DM.
We evaluated the effects of consuming one egg per day for a relatively extended period (five weeks) versus 1/2 cup (40 g) of oatmeal per day on plasma glucose and inflammatory markers, our primary endpoints. Our secondary endpoints included plasma lipids, markers of oxidative stress, and parameters of glucose metabolism, such as glycosylated hemoglobin (HbA1c). We hypothesized that eating one egg per day would not adversely affect primary or secondary endpoints when compared to an oatmeal breakfast.

We further hypothesized that eggs would reduce inflammatory markers in this population, likely due to the presence of highly bioavailable carotenoids" (Ballesteros. 2015).Twenty-nine subjects, 35–65 years with glycosylated hemoglobin (HbA1c) values <9% (this means they were diabetic, but not really "sick") were recruited and randomly allocated to consume isocaloric breakfasts containing either one egg/day or 40 g of oatmeal with 472 mL of lactose-free milk/day for five weeks.
|The cholesterol efflux which improved in response to egg consumption in another study was unfortunately not assessed in the study at hand.|

However, after adjusting for gender, age and body mass index, aspartate amino-transferase (AST) (p < 0.05) and tumor necrosis factor (TNF)-α (p < 0.01), one of our primary endpoints were significantly reduced during the egg period.
