Eggs have been a dietary staple for centuries, celebrated for their versatility and nutritional profile. They’re a breakfast favourite and a key ingredient in countless baked goods, playing a crucial role in binding ingredients and providing structure. However, despite their popularity, eggs have also been at the center of numerous health debates, from cholesterol concerns to misconceptions about storage and preparation.One common myth is that egg yolks are detrimental to heart health due to their high cholesterol content. According to Healthline, a large egg contains around 212 milligrams of cholesterol. Yet, research suggests that dietary cholesterol has less impact on blood cholesterol levels than previously believed. Harvard Health Publishing highlights that the liver produces the majority of bodily cholesterol based on saturated and trans fat intake rather than dietary cholesterol. Tony Castillo, an elite sports dietitian, affirms that eggs can be safely included in a heart-healthy diet for most individuals, referencing a Harvard study that found no link between egg consumption and heart disease risk.Another prevalent misconception is that brown eggs are more nutritious than white eggs. According to the U.S. Department of Agriculture (USDA), egg color is determined solely by the breed of the hen. Nutritionally, white and brown eggs are nearly identical unless specified as nutritionally enhanced through fortified feed. Castillo further explains that the hen’s earlobe colour can indicate the egg color — white earlobes typically produce white eggs, while red or brown earlobes produce brown eggs.Cage-free, free-range, and pasture-raised labels can also be misleading. While cage-free hens are not confined to small cages, they are usually kept indoors, with varying space and enrichment conditions. Free-range and organic labels, regulated by the USDA, require outdoor access for hens. However, pasture-raised eggs offer the most outdoor space, though these standards are not strictly regulated, urging consumers to research farm practices.The myth that raw eggs are superior for protein intake gained traction in the 1970s and 1980s, thanks to movies like "Rocky." However, cooking eggs actually enhances protein absorption. A 2022 study published in the Journal of Nutrition found that protein levels were consistent regardless of whether eggs were consumed raw or cooked. Additionally, raw eggs pose a higher risk of salmonella infection.Despite being considered a good source of iron, eggs are not particularly effective in boosting iron levels. Only 3.7% of the iron in eggs is absorbed by the body, and compounds in egg yolks can inhibit iron absorption. Experts recommend consuming eggs with vitamin C-rich foods to enhance iron bioavailability.Many people also believe that floating eggs are unsafe to eat. While the float test can indicate an egg’s age, it is not a reliable indicator of bacterial contamination. Dr. Don Schaffner, a food safety expert, advises checking for spoilage through appearance and smell rather than relying solely on the float test.Finally, misconceptions about egg storage and pregnancy persist. While store-bought eggs in the U.S. require refrigeration due to washing that removes the protective cuticle, unwashed eggs from local farms may be safely kept at room temperature for up to two weeks. Pregnant individuals can safely consume thoroughly cooked or pasteurized eggs, which are rich in essential nutrients like choline and vitamin B12, crucial for fetal brain development.
