In the study, researchers recorded the number of eggs eaten and packs of cigarettes smoked as recalled by each adult (average age 62). Everyone in the study had been referred to a vascular prevention clinic at a Canadian hospital, meaning their heart health (and the habits that led them there) was already in question. The researchers found that, as expected, plaque build-up in their subjects' carotid artery thickened with age, and even correlated with smoking and egg-eating habits.
Publications like The Daily Mail and Fox News have reported blindly on the matter, but thankfully there are others out there suspiciously raising eyebrows.
The UK's National Health Service points out some of the study's limitations, including:
- The accuracy of the participants' recollections of egg yolk consumption.
- A lack of details regarding how the eggs were cooked (or not).
- Disregard for other factors of heart disease advancement, including but not limited to exercise, alcohol consumption, antidepressant use (antidepressants have been shown to cause arteries to thicken 400% faster than aging,) and other important dietary factors.
- The harmful effects of the chemicals and hormones found in non-organic eggs.
- The effects on the human body from eating eggs from chicken given GMO feed.
- The living condition of the chickens.
Organic eggs from healthy chickens on GMO-free feed have actually shown in many studies to prevent heart disease. They contain healthful amounts of protein, vitamin B, omega-3 fatty acids, and many nutrients like lutein and zeaxanthin, which reduce risk for age-related macular degeneration (AMD), a major cause of blindness.
The key? Moderation, as with most things, and buying organic eggs from local farmers who can raise their chickens in truly cage-free conditions. Happy, healthy chickens produce more healthful eggs.
