Whether poached, hard-boiled or fried, you probably still serve your eggs with a dollop of doubt. Are they a healthy option? What about cholesterol levels? How many is too many?<\/p>\n
From the positive \u201cGo to work on an egg\u201d campaign of the 1950s and 1960s, to the salmonella scare and then the dire cholesterol warnings of the 1980s and beyond, eggs have certainly had a chequered history.\u00a0\u00a0<\/p>\n
\u201cIn the 20 years that I\u2019ve been a dietitian, I\u2019ve seen recommendations around eggs change many times,\u201d says Victoria Taylor, senior dietitian at the\u00a0British Heart Foundation (BHF)<\/a>.<\/p>\n \u201cIt\u2019s not surprising that the most common question I\u2019m asked by a confused public is whether it\u2019s safe to eat them if you have cardiovascular disease. The answer is a reassuring yes.\u201d\u00a0\u00a0<\/p>\n What\u2019s the link between eggs and cholesterol?<\/p>\n Older studies stated that the high cholesterol in yolks (177mg in a medium egg) raised our own levels of cholesterol, and therefore increased the risk of heart disease.\u00a0\u00a0<\/p>\n But it is now known that, for most people, dietary cholesterol does not significantly raise blood cholesterol. In fact, only a third of our cholesterol comes from our diet (our liver makes the rest).\u00a0\u00a0<\/p>\n \u201cPrevious studies have been observational, so only show an association rather than cause and effect,\u201d says Taylor. \u201cIt was difficult to pull out whether it was eggs or the rest of the diet that was increasing the risk.<\/p>\n “Saturated fats found in meat and dairy are now known to have a much more harmful effect on your levels of \u2018bad\u2019 cholesterol than dietary cholesterol. Eggs are low in saturated fat.\u201d\u00a0\u00a0<\/p>\n A study<\/a> of 177,000 people in 50 countries published in The American Journal of Clinical Nutrition in 2020 backed this, finding no significant association between the consumption of eggs and raised blood lipids or cardiovascular disease. <\/p>\n And an eight-year Chinese study published in 2022 went further, finding that eating three to six eggs a week was associated with a lower risk of mortality than eating none.<\/p>\n Is there a limit to how many eggs I should eat?<\/p>\n Health bodies used to advise eating no more than four eggs a week. But in 2000, the then Department of Health and the BHF both changed their advice, and there is now no upper limit for healthy adults.\u00a0\u00a0<\/p>\n Most recently, analysis of the diet of 8,000 older people (mostly in Australia) published in 2025 found that those who ate 1-6 eggs a week had the lowest risk of death during the study<\/a>, which is ongoing.\u00a0<\/p>\n The news is even good for people at risk of heart disease. Original National Institute for Clinical Excellence (NICE)<\/a> guidelines from 2014 advised those at risk to eat less than 300mg a day of dietary cholesterol, but that guidance was removed in 2023.\u00a0\u00a0<\/p>\n There is an exception to the rule, says Taylor. \u201cPeople who have familial hypercholesterolemia [an inherited condition where you have exceptionally high levels of cholesterol] are still advised by NICE to eat less than 300mg of dietary cholesterol a day, as they need to take more care than the general population.\u201d\u00a0<\/p>\n Which is healthier \u2013 yolk or white?<\/p>\n Eggs are like a supplement in natural packaging, and the yolk is the most nutrient-dense part,\u201d says Laura Southern, a nutritionist from London Food Therapy<\/a>.<\/p>\n \u201cEgg white is just 90% water and 10% protein. When advising older clients on ways to protect their bones and brains, I always recommend eggs because they are an easy, inexpensive way to pack in a lot of protein and vitamins.\u201d\u00a0\u00a0<\/p>\n Protein<\/a> is especially important for the over-60s, agrees Dr Sue Reeves, a nutritionist at the University of Roehampton<\/a>. \u201cIt helps maintain muscle mass and delay frailty,\u201d she says.<\/p>\n \u201cBecause eggs work well in breakfast, lunch or dinner, they encourage a more even distribution of protein throughout the day, which has been shown to better stimulate muscle growth than skewing all protein consumption to the evening meal.\u201d\u00a0\u00a0<\/p>\n Protein also helps you feel fuller for longer, which might explain why people who eat at least five eggs a week are slimmer than those eating none, according to a Spanish study<\/a>\u00a0published in Clinical Nutrition in 2022.\u00a0\u00a0<\/p>\n Eggs are good for eye and brain health<\/p>\n Not only are eggs a good source of vitamin B12 (essential for cognition and energy), vitamin A (eye health) and vitamin D (bone health, immunity), they are abundant in two lesser-known nutrients: lutein and choline.<\/p>\n \u201cLutein is a polyphenol antioxidant found in yellow and orange foods, and eggs are one of the most concentrated sources of it,\u201d says Southern. \u201cSupportive of the retina, it can prevent cataracts and macular degeneration.\u201d\u00a0\u00a0<\/p>\n Choline is an essential nutrient for brain health, yet 90% of the US population is deficient in it, according to figures (similar data does not exist for the UK). <\/p>\n \u201cBecause it helps with focus and memory, it\u2019s often used in supplement form for children with ADHD, but it\u2019s just as beneficial for older adults,\u201d says Southern. <\/p>\n
