Aside from being a well-written and mostly well-researched article, there are a couple things that just aren't sitting right with me.
For starters, the study from Iowa State University looks to be sponsored or at the very least promoted by the "Egg Nutrition Center," (see end of article) so I'd argue more than a slight conflict of interet there.
The study concerning postmenopausal women and TMAO levels is the same, stating "the project described was supported by the Egg Nutrition Council," and making these findings incredibly biased.
Since being taken to the supreme court in 1977 for 'false advertizing and misleading health claims", the egg industry has spent hundreds of millions of dollars in attempts to get the research, and the general public, on its side.
What's more is that the caveat you use at the end really bothers me. You conclude that it's safe to "eat as many eggs as you want per day, as long as the overall diet is relatively low in saturated fats and red meat."
Well... does that really means eggs are healthy and safe to eat if there's a laundry list of conditions in order to make them so?
Broccoli and oatmeal, for example, aren't only healthy when eaten with a low meat diet... they're foods that are healthy no matter what! Are eggs really the kind of food you want to be promoting as healthful?
I'm being a bit tongue in cheek here, but they can kill you if you don't cook them properly for god's sake! Plus they result from the culling of day-old chicks, plus they shouldn't really be eaten with a diet high in saturated fats and/or red meats.
That's a whole lot of pluses and ones, I'd argue, that outweigh any potential health benefit. I hope you don't mind my comment, it's clear you're a superb writer!
