An egg a day is not a health risk.
Now it shows a large international studio.
– It does not affect blood fats, cardiovascular disease or death, says Annika Rosengren, professor of medicine.

In a worldwide study, researchers examined whether an egg a day increases the risk of high blood fats, high blood pressure, heart attack, stroke, or death.
Now the study is complete, with gratifying results for all egg lovers.
– You don’t have to be afraid of eggs, but you can eat one egg a day. We can see that there is no increased risk, says Annika Rosengren, a professor of medicine at the University of Gothenburg, who led the Swedish part of the study.
The result applies not only to healthy people, but also to those who are at risk for cardiovascular disease and those who already have it.
– Those who have had some form of cardiovascular disease have a higher risk of getting sick again, compared to healthy ones, but eggs do not affect that risk.
Eggs contain cholesterol. The cholesterol we get from eggs is only a very small part of the LDL cholesterol in the blood (the “bad” cholesterol).
However, we do not get most of our cholesterol through our diet – it is produced in the body.
– Preferably from saturated fat, says Annika Rosengren.
The foods that contribute to the production of cholesterol are saturated fats in red meats, cold cuts and fatty dairy products, such as butter.
The body needs cholesterol for cell structure and the brain. However, we don’t need a lot, and the body can make the cholesterol we need.
– Therefore, the need for cholesterol through the diet is very low.

Therefore, the dietary advice for lowering LDL cholesterol is to reduce your intake of foods that contain saturated fat. And instead, increase your intake of greens, greens, fatty fish, such as salmon, mackerel, herring, as well as vegetable oils and fats, such as olives and rapeseed, but not coconut oil.
– This is not a novelty, but we would like to eat a diet that contains a lot of proteins and fats of plant origin and limit the intake of red meat and fatty dairy products, says Rosengren.
Whether eggs are dangerous to health or not has been debated and researched for decades. Advice has varied over the decades, from banning eggs to eating eggs safely.
Conflicting research results can lead us not to know what to believe.
Why should we trust these particular research results?
– Yes, that’s a good question.
– It is a very large study carried out on many people in different countries and consists of three sub-studies that show the same thing. The larger the studies, the lower the risk of random findings, says Annika Rosengren.
The study had 177,000 participants in 50 countries. 4,000 people participated in the Swedish part of the PURE study. They were between the ages of 35 and 70 when the study began in 2005. It was published in The American Journal of Clinical Nutrition in April 2020.
Eggs are in fact a little food bomb, packed with high-quality minerals, vitamins, and protein.
– By the time you are over 80 years old, your appetite may not be as good and you may have a hard time getting a sufficient nutritious diet.
– Then eggs are very good food, says Annika Rosengren.
The Heart-Lung Foundation has supported the study with research grants.
– That research shows that in the fall of life you can eat eggs with a clear conscience every day is good news, especially for everyone who has to think about their cholesterol levels and their nutritional intake, says Kristina Sparreljung, secretary general.
