The egg white mostly consists of protein. Raw eggs are nutrient-dense and packed with protein, good fats, vitamins, minerals, and antioxidants that protect your eyes, brain, and heart. The yolks contain most of the nutrients. Eggs are one of the best sources of animal protein out there.
In fact, they contain all 9 essential amino acids. However, according to one very small, much older study, eating the eggs raw may decrease your absorption of these quality proteins.
This issue with absorption is something to consider if eggs are your main source of protein, but the size and date of the study make it impossible to draw any real conclusions. Biotin is a water-soluble B vitamin, also known as vitamin B7. While egg yolks provide a good dietary source of biotin, raw egg whites contain a protein called avidin. Avidin binds to biotin in the small intestine, preventing its absorption. Because heat destroys avidin, this is not an issue when the egg has been cooked 7 , 8.
For that to happen, you would need to consume raw eggs in large amounts every day 9. Raw egg whites contain the protein avidin, which may block the absorption of biotin, a water-soluble B vitamin. Raw and undercooked eggs may contain Salmonella , a type of harmful bacteria Indirect contamination can happen during the production process, during handling, or during food preparation Symptoms of Salmonella food poisoning include stomach cramps, diarrhea, vomiting, and fever.
These symptoms usually appear 6 hours to 6 days after contracting an infection and may last 4 to 7 days after eating the food contaminated with the bacteria 1. In , it was estimated that Salmonella caused around 1 million instances of illnesses in the United States 11 , Pasteurization is one method that is often employed to prevent the possibility of Salmonella contamination.
This process uses a heating treatment to reduce the number of bacteria and other microorganisms in foods The U. Department of Agriculture USDA considers it safe to use in-shell raw eggs if they are pasteurized Raw eggs may contain a type of pathogenic bacteria called Salmonella , which can cause food poisoning.
So infants, children, pregnant women and elderly people can now safely eat raw or lightly cooked hen eggs, or foods containing them. Make sure that the eggs you buy have a British Lion stamp mark.
They should have these eggs cooked through until the white and yolk are solid. This is because these groups are more vulnerable to infection and likely to have more serious symptoms of food poisoning.
People who have a severely weakened immune system and who are on a medically supervised diet prescribed by health professionals should cook all eggs thoroughly. If you're concerned about raw egg when eating out or buying food, ask the person serving you if it contains raw egg and if so, if the eggs have the British Lion stamp. There can be bacteria on the shell as well as inside the egg, which can spread very easily to other foods, as well as to hands, utensils and worktops.
