Protein, cholesterol, energy… Here’s what really happens to your body when you eat eggs every day

An egg contains around 6 g of complete protein, rich in all essential amino acids. Sports enthusiasts love them: eating eggs every day promotes muscle recovery and satiety. It's also an interesting alternative to meat, cheaper and easier to cook.

Eating an egg a day means filling up on nutrients: vitamins A, D, E and B12, as well as iron, zinc and selenium. Eggs even contain choline, an essential nutrient for brain function and memory.

One egg provides around 200 mg of cholesterol. For a long time, people were advised to limit their consumption. But recent studies show that dietary cholesterol has much less impact on blood cholesterol than previously thought. For most healthy people, one egg a day poses no problem (source: Inserm). However, people suffering from hypercholesterolemia should seek advice from their doctor.

Eggs contain lutein and zeaxanthin, two antioxidants that protect the retina and reduce the risk of age-related macular degeneration. Its vitamins A and E also contribute to the beauty of skin and hair.

As always, it's the excess that's the problem. Three to seven eggs a week are enough to enjoy their benefits without excess saturated fat. Cooking methods also count: a hard-boiled or soft-boiled egg is much healthier than one fried in butter.
